Apache HttpClient 5.0 migration guide
Home Page: https://ok2c.github.io/httpclient-migration-guide
Hi Oleg,
thank you very much for the migration guides. I am currently migrating an application using httplient 4.5.x to httpclient5. The code uses EntityUtils#toString(HttpEntity)
to parse the response body to text. During the migration, I discovered that ParseException
was made a checked exception compared to being a RunTimeException
before. This forces me to take of the exception. Was this an intended changed? Do you know why?
Best regards,
Gregor
Hi there.
I noticed that when I send a request with CloseableHttpAsyncClient using Apache HttpClient 5.0, it runs into an exception “No tunnel unless connected” when requesting via HTTPS. However with HTTP, everything works as normal.
Code works perfectly when proxies are not used.
` try{
sslContext = SSLContexts.custom()
.setProvider(Conscrypt.newProvider())
.build();
}catch (Exception e){
e.printStackTrace();
}
final PoolingAsyncClientConnectionManager cm = PoolingAsyncClientConnectionManagerBuilder.create()
.setTlsStrategy(new ConscryptClientTlsStrategy(sslContext))
.build();
BasicCredentialsProvider credentialsProvider = new BasicCredentialsProvider();
if (proxy.isAuth()) {
credentialsProvider.setCredentials(
new AuthScope(proxy.getIp(), Integer.parseInt(proxy.getPort())),
new UsernamePasswordCredentials(proxy.getUsername(), proxy.getPassword().toCharArray()));
}
HttpHost p = new HttpHost(proxy.getIp(), Integer.parseInt(proxy.getPort()), "http");
asyncClient = HttpAsyncClients.custom()
.setVersionPolicy(HttpVersionPolicy.FORCE_HTTP_1)
.setConnectionManager(cm)
.setUserAgent(Utils.USER_AGENT)
.setDefaultCookieStore(cookieStore)
.setDefaultCredentialsProvider(credentialsProvider)
.setProxy(p)
.build();
asyncClient.start();`
thank you!
Hi ok2c;
Because the httpcomponents-core project has no issues entry, I open an issues here.
