Is it possible to use PromiseKit to handle header-only response? about promisekit HOT 18 CLOSED

I'd say, yes, it should handle this and this is a bug. Let me look into it.

from promisekit.

Well, this isn't strictly a header only response. It claims the response length is 1 and the content is JSON. PromiseKit reads that and tries to decode JSON from the 1 byte response and fails, so fails the response.

Not sure what to do here.

from promisekit.

For now you can do:

- (PMKPromise *)myPromise:(id)args {
    id rq = [OMGHTTPURLRQ POST:url:args];
    id q = ;
    return [PMKPromise new:^(PMKPromiseFulfiller fulfill, PMKPromiseRejecter reject){
        [NSURLConnection sendAsynchronousRequest:rq queue:q completionHandler:^(id rsp, id data, NSError *urlError) {
            if (urlError) {
                reject(urlError)
            } else {
                fulfill(nil);
            }
        }];
    }];
}

from promisekit.

thank you for the snippet, will try it out and report :)

from promisekit.

You'll need to #import <OMGHTTPURLRQ.h> too. That will work as PromiseKit depends on it.

Closing as I believe the issue is the web-server’s response is invalid.

from promisekit.

Turns out this is a common Rails work around. So I have hard-coded detection in v0.9.14.3 that will allow it.

Let me know if it works.

from promisekit.

I have tried the OMGHTTPURLRQ approach (the snippet) to get header-only response from rails 4.1.4 (head 200), it worked as expected ('then' is called and 'catch' is not called)

from promisekit.

@mxcl
would like to try out v0.9.14.3, any way to install it using cocoapods?
I tried " pod 'PromiseKit', '0.9.14.3' " but it doesn't install (Error name: Unable to satisfy the following requirement)

from promisekit.

Does it not say what requirement it cannot satisfy?

from promisekit.

the only requirement
" pod 'PromiseKit', '0.9.14.3' "

from promisekit.

What CocoaPods command are you running to generate this error? More information please.

from promisekit.

i used "pod install --no-repo-update", the flag is used because executing "pod install" always remain at the step "analyzing dependency", adding the flag prevents the problem

from promisekit.

Without a repo update you cannot get the new PromiseKit, hence the error.

from promisekit.

ahhh, i get it, you are right. silly me.

from promisekit.

will try to pull version 0.9.14.3 and try it out

from promisekit.

Yes, PromiseKit version 0.9.14.3 worked as expected ( Rails 4.1.4 is used for server btw ), it correctly does the following:

head 200 response -> execute 'then' and then 'finally'
head 500 response -> execute 'catch' and then 'finally'

from promisekit.

For the sake of others' information, I solved the pod install hanging problem by executing the following commands:

pod repo remove master
pod setup
pod install
