curlpp's Issues

There is no configure file

I was trying to build this library on linux (CentOs) but unable to find configure file.

make failed after cmake ..

I am trying to build curlpp locally on machine, using cmake version 3.2 in following steps.

git clone [email protected]:jpbarrette/curlpp.git
cd curlpp && mkdir build && cd build && cmake ..
make
and it fails here, Please find the build log

And any possible solution to this.

WriteSteam Typo

curlpp/examples/example01.cpp

Line 85 in 5fa2ea6

// we would use the WriteStrem option like this:

WriteStream was written, WriteStrem
I know... super not important

Examples and guide say we should use Cleanup class but we shouldn't

Examples and guide use Cleanup class, but Cleanup class comments say it is deprecated and not to use it. This causes confusion on how to use this library.

/**
* \depreciated This is an obsolete class. DO NOT use it. 
*
* The only reason it's still here,
* is to be sure that it is backward compatible. This class was taking care of 
* initialization and cleaning up curlpp (also libcURL) (it was calling 
* curlpp:terminate() in his destructor). However, from now on, you do not need
* this class. Note that the removal of this class was done because it was 
* raising some threading issues.

sftp support ?

according to libcurl website , they suppoert sftp , and they actually do , i coded a simple sftp client , do you suppoert a wrapper for this protocol ?

example18.cpp HAVE_BOOST

After ./autogen.sh and ./configure and make project can't be built under Ubuntu 16.06. HAVE_BOOST is not defined when example18.cpp is compiled.

Why this check is even there?

is it possible to perform a GET request to a rest server, doesn't show the response payload on stdout but get the response code?
with ostringstream I can't analyze response code but with perform method it show me response on stdout.

How to add curl library in curlp for build?

When I build a library in a process I have errors like these:

libcurl/7.50.3@lasote/stable: Not found in local cache, looking in remotes... libcurl/7.50.3@lasote/stable: Trying with 'conan-center'... ERROR: Unable to find 'libcurl/7.50.3@lasote/stable' in remotes
How to add libcurl on the build? I make in VS 2015. Thanks.

cannot build in linux: required file './README' not found

In linux, calling ./autogen.sh to create ./configure exit with an error:

configure.ac:9: installing './missing'

After creating an empty README ./autogen.sh works correctly

Send parameters in GET request ?

Is it possible to url parameter in GET request.
Example :

base_url : https://api.example.com/
methods_name : <some_method_name>/<param1>/<param2>/..../<param3>

Different methods will accept different parameters. Instead of hard-coding and modifying base_url with parameters every time. I wish to send url_params separately, and it modify the base_url depending upon parameters.

curlpp configure.ac wipes out CXX optimisation flags

I've noticed that the autotools build system that comes with 0.7.3 deliberately passes CXXFLAGS through a sed filter to remove anything matching -O[0-9]*. Why is this? I was attempting to pass -O3 as part of my configure for a powerpc-linux cross compile and was surprised to see that CFLAGS were preserved but CXX was not.

The following error occurs on linux gnu (Ubuntu 18.04) distro. Am I missing a package? Which undefined resolution is left out?

SMTP support?

Hi,
is SMTP supported by curlpp?
If not, will it be supported in the future? Any plan for that?
if yes, may I have an example sending an email using curlpp?

RuntimeError Exception: No url set on VS 2015!

I am new to the curlpp library and would like to see why my program is dealing with this exception. I take the code from github example00.cpp. Tell me how this exception needs to be processed in order for the program to work correctly?

Make visual Studio Community Project files.

On Windows you do not need a lincense to use Visual Studio Community. With Community you get everything that is in all the other editions of visual Studio for free as well. So, all the more reasons to make one. I could even Pull request some if you would like because I use the latest Update to Visual Studio Community 2015.

Silent GET request

i asked this question in another issue, but the solution doesn't work for me:
Iis it possible to perform a GET request to a rest server, doesn't show the response payload on stdout but get the response code?
with ostringstream I can't analyze response code but with perform method it show me response on stdout.

Connection is broken but not cancelled

curlpp: 0.8.1
curl: 7.59.0
OS: Gentoo Linux

I'm writing a program that makes a very long lasting connection. I noticed that there is no data incoming after a while but perform() is not returning. Would it be possible that curlpp detects if a connection is broken and cancel it?

Here is an example program:

#include <string>
#include <iostream>
#include <functional>
#include <thread>
#include <chrono>
#include <ctime>
#include <curlpp/cURLpp.hpp>
#include <curlpp/Easy.hpp>
#include <curlpp/Options.hpp>
#include <curlpp/Infos.hpp>

using std::string;
using std::cout;
using std::chrono::system_clock;
using namespace std::placeholders;  // _1, _2, _3

const size_t callback(char* data, size_t size, size_t nmemb, string *str)
{
    str->append(data, size * nmemb);
    cout << "Received " << size * nmemb << " Bytes\n";
    return size * nmemb;
};

void get_stream(string &stream)
{
    curlpp::Easy request;

    request.setOpt<curlpp::options::Url>
        ("https://botsin.space/api/v1/streaming/hashtag?tag=test");
    request.setOpt<curlpp::options::WriteFunction>
        (std::bind(&callback, _1, _2, _3, &stream));

    request.perform();
    cout << "Connection lost\n";
}

int main(int argc, char *argv[])
{
    curlpp::initialize();
    
    string stream;
    std::thread thr(get_stream, std::ref(stream));

    while (true)
    {
        std::this_thread::sleep_for(std::chrono::seconds(10));
        std::time_t tt = system_clock::to_time_t(system_clock::now());
        cout << std::ctime(&tt) << stream << std::endl;
        stream.clear();
    }

    thr.join();
    
    curlpp::terminate();
    return 0;
}

And here is the produced log: curlpp.log (The ":thump" are heartbeat comments, sent every ~15s)

Remove unnecessary null pointer checks

An extra null pointer check is not needed in functions like the following.

Warning during compilation

Hi. I'm using your nice wrapper in a C++ project pulling some XML-data from the web. The project is in eclipse (mars). When compiling I would get a warning. The fix was very simple, merely adding a */ to the end of the line.

Wrong RelativePath in curlpp.VC8.vcproj

The files LifetimeLibrary.cpp and PrivateMembers.cpp are both located in .\src\utilspp\ but the project points to .\src\utilspp\singleton

I got the compiler error message that neither could be found.

Solution: I changed the RelativePath in the file properties within VisualStudio, but i think changing the entry in the curlpp.VC8.vcproj file with a text editor will do the trick too.

Centos7: Cmake 2.8 support

Hi,
I was trying to build the lib on Centos7. This OS ships with cmake 2.8.12
I KNOW this is an old version and is missing many nice features, but Centos7 is the newest free edition of the probably most widely used GNU/Linux distribution in an enterprise environment. So: How about keeping compatibility with Centos7? (Centos7 ships with libcurl 35, dated, but again: probably most widely used, gcc is 4.8.5 with about 95% completeness of C++11 support)
I can try to create a CMakeList.txt for cmake 2.8, but wonder about your plans to keep support for this edition? Redhat plans to provide production support for RHEL7 until 2024.

Documentation link is dead

From Readme, Documentation section:
The programming guide for the 0.5.x and newer versions is here., with here leading to https://github.com/jpbarrette/curlpp/blob/master/guide.pdf which is 404.

server is not exist block error

when server is not exist,or The server did not respond.
curlpp::Easy request will block for very very long time.
when i use request.setOpt(new Timeout(1));
it has little work.

Any HTTPS examples?

Or is there no extra configuration needed to make HTTPS requests?

[Bug] vanilla POST request halt bug report

I found a bug to report...

I'm using curlpp 0.8.1 on Ubuntu 16 x86-64.

When I requested vanilla POST with no body,
the perform() halts with no error.
This is when I use curlpp::options::Post(true)

When I tried changing Post(true) to PostFields("") and PostFieldSize(0), it worked just fine.
I found a libcurl example(https://curl.haxx.se/libcurl/c/CURLOPT_POST.html), although I didn't tried running this code, documentation suggests that it should work.

Please review this bug.

Here is a snippet of code

Thank you.

// snippet 1
stringstream ss;
Easy request;

request.setOpt(new Url("some url"));
request.setOpt(new Post(true));

// halts here
ss << request;

// snippet 2
stringstream ss;
Easy request;

request.setOpt(new Url("some url"));
request.setOpt(new PostFields(""));
request.setOpt(new PostFieldSize(0));

// this works just fine
ss << request;

can support Streamed requests?

I want to use streams in a program I am writing， like java okhttp3， can you support?

Incorrect char buffer in WriteFunctionFunctor call back

When receiving large JSON data set as multiple chunks via WriteFunctionFunctor callback, I notice incorrect/unprocessed char* ptr being returned whose size is much more than size X nmemb. The callback signature for WriteFunctionFunctor is as below.
typedef utilspp::Functor<
size_t,
TYPE_LIST_3(char*, size_t, size_t)> WriteFunctionFunctor
I am attaching the original JSON file and the file written as received via multiple WriteFunctionFunctor callbacks.

Please compare the attached files and you could notice an unprocessed or incorrect JSON formation inbetween.

Also you could see a '0' character at last in the receivedJSON which shows the HTTP Chunk Encoding is not properly processed(not being removed which marks the end of data/HTTP response) before being returned to the callback function.

istream reads may never finish

While writing a simple file upload routine, we discovered that the upload would seemingly hang until eventually the connection timed out.

We discovered that the problem was in curlpp's use of readsome. If no data was available for readsome, it returned 0, without ever buffering more data to read. (This may depend on the particular istream subclass and the particular C++ RTL; we're using a std::stringstream in Embarcadero C++Builder 10.) curlpp didn't treat 0 bytes read as an abort, but it also didn't ever buffer more data to read, and it apparently didn't do anything to continue or abort the HTTP transfer.

This answer suggests that readsome is "fairly useless" and "highly implementation-specific," so read seems to be a safer choice.

C2491 31 Times on inl files

Receiving numerous errors when installing from Nuget related to C2491.
Others are recieving the same problem.
Problem can be recreated by Going into VS17 and creating a console app that uses the version of curlpp from nuget.
Try any of the example programs eg example04.
Problem occurs.

Disable auto logs

How can I disable the logs automatically printed by curlpp, I can't find the print code in the code.Thanks!

Release a new version

Hello, could you please make a new release that includes the GCC 6 fixes? This will give me enough time to make sure it goes into the next version of Debian stable. Thanks!

curlpp.pc: doesn't contain version number

The resulting curlpp.pc file doesn't contain a version number after using cmake prior to build curlpp. I suspect that this explains why my package cannot require curlpp for version >= 0.8.1 appropriately. I am using autotools for building. See the following:

configure: error: Package requirements (curlpp >= 0.8.1) were not met:

Requested 'curlpp >= 0.8.1' but version of curlpp is

Consider adjusting the PKG_CONFIG_PATH environment variable if you
installed software in a non-standard prefix.

Alternatively, you may set the environment variables CURLPP_CFLAGS
and CURLPP_LIBS to avoid the need to call pkg-config.
See the pkg-config man page for more details.

Even though you seem to have dropped autotools as build system, I think that other packages using other build system should still be able to require curlpp for a specific subset of versions. This means, you should fix the curlpp.pc file if I'm not mistaken.

Replace auto_ptr with either shared_ptr or unique_ptr

GCC6 has C++14 as default, and auto_ptr was deprecated in C++11. The suggestion is to port auto_ptr over to shared_ptr or unique_ptr as required. More information here: https://gcc.gnu.org/gcc-6/porting_to.html

Since Fedora 24 defaults to GCC6 and errors at the use of auto_ptr, curlpp doesn't currently build there. Bug here: https://bugzilla.redhat.com/show_bug.cgi?id=1307415

curlpp-config doesn't work

Is it possible to build this library for android?

Building in msvc requires makefile, but it's non existant

Win32 Documentation states to use the makefile, however all msvc makefiles that I could see from a few years back and now not included and .gitignore d.

Either documentation out of date or user error. Can't proceed to install using option C in the meantime.

@libdir@ pkg-config template substitution broken

At configure time extras/CMakeLists.txt performs a template substitution of the pkg-config manfiest extras/curlpp.pc.in.

Trying to compile with g++ using the libcurlpp library fails with the following:

../libtool: line 7485: cd: lib/x86_64-linux-gnu: No such file or directory
libtool:   error: cannot determine absolute directory name of 'lib/x86_64-linux-gnu'
Makefile:808: recipe for target 'heliosd' failed

This is because the substitution variable for the library path @libdir@ is missing a leading forward slash:

$ pkg-config --libs curlpp 
-Llib/x86_64-linux-gnu -lcurlpp -Wl,-Bsymbolic-functions -Wl,-z,relro -lcur

This can be fixed by modifying CMakeList.txt's...
set(libdir "${CMAKE_INSTALL_LIBDIR}")

...to...
set(libdir "/${CMAKE_INSTALL_LIBDIR}")

I recommend the template look something like this:

# This is a comment
prefix=@prefix@
exec_prefix=${prefix}
includedir=${prefix}/include
libdir=${exec_prefix}/lib

However i have found one cosmetic issue, that curlpp::infos::XX::get gives different output than InfoGetter. InfoGetter always gives correct results.

Sample code

double download_time, download_speed, download_time2, download_speed2;

curlpp::InfoGetter::get(request,CURLINFO_TOTAL_TIME, download_time);
curlpp::InfoGetter::get(request,CURLINFO_SPEED_DOWNLOAD, download_speed);

curlpp::infos::TotalTime::get(request, download_time2);
curlpp::infos::SpeedDownload::get(request, download_time2);

Strange thing for me was that
curlpp::infos::ResponseCode::get(request) was working as it should and i have found the problem.
This function defined in Info.cpp

template<>
void
InfoTypeConverter<double>::get(const curlpp::Easy & handle, 
				 CURLINFO info,
				 double & value)
{
  curl_off_t tmp;
  InfoGetter::get(handle, info, tmp);
  value = (double)tmp;
}

for some strange reason wants to put double inside a long. What actually this does is, it inserts time which is double into long removing the floating point. After that the conversion to value just randomly inserts floating point back. I haven' t tested it as i end up with using InfoGetter directly, but this should fix the problem.

template<>
void
InfoTypeConverter<double>::get(const curlpp::Easy & handle, 
				 CURLINFO info,
				 double & value)
{
  InfoGetter::get(handle, info, value);
}

How do I download this library

There are a lot of files, and I'm relatively new to C++.
The only thing that the front page tells me is to visit https://github.com/jpbarrette/curlpp/
for how to download. But I am already on this page, and it confuses me.

If someone could give me a hint, that would be hugely appreciated.
Thanks.

double call to CurlHandle destructor

Hi,

I am experiencing a weird crash, which trace looks like:

This comes in the context of using multiple threads, each creating an object with its own curlpp::Easy handles. I've carefully investigated, tried many variants, tried against current master branch, but could not find the cause.

The calling code looks like:

curlpp::Easy request;                                                                                                                                           
curlpp::options::WriteStream ws(&os);  
curlpp::options::CustomRequest pr(http_method);  
request.setOpt(new curlpp::options::Url(url));
request.setOpt(ws);
request.setOpt(pr);
request.perform();
outstr = os.str();                                                                                                          
outcode = curlpp::infos::ResponseCode::get(_request);

This is on Ubuntu 14.04 using the built-in packages (though curlpp master yields the same error).

Any help is greatly appreciated!

Unable to find LIB_CURL

I installed libcurl (v7.51) on Windows via CMake, with out any problems. It is installed in C:/Program Files (x86)/CURL, as expected. However, when I try to generate a project from cmake, it fails to find libcURL.

I'm at a loss to explain why it would fail like this...

Cross Compile Error

Cross Compiled by arm-none-linux-gnueabi-gcc it seems that taking -I/usr/local/include and -L/usr/local/lib in Makefile is quite harmful for cross compile.Hope for improvement.

[question] status of CURLPP project

at this time:

there are 5 openned Issues and 3 PR. the oldest item was openned more than half a year ago.
some planned features (eg CMAKE support) were not fully implemented.
almost all files in master branch dated by 2009.

is this a "dead" project? does somebody really support it?

CMake build requires missing directory

CMake Error at src/utilspp/CMakeLists.txt:4 (add_subdirectory):
add_subdirectory given source "singleton" which is not an existing
directory.

It fails this way for in source and out of source builds.
