hi, folks,
I'm working with httpclient (4.2.1) on suse linux enterprise
server 11(x86_64), and construct the connectionpool manager code as follow:
KeyStore keyStore = getKeyStore(KEY_STORE_CLIENT_PATH, KEY_STORE_CLIENT_PASS);
KeyStore trustStore = getKeyStore(KEY_STORE_TRUST_PATH, KEY_STORE_TRUST_PASS);
socketFactory = new SSLSocketFactory(keyStore, KEY_STORE_CLIENT_PASS,
trustStore);
socketFactory.setHostnameVerifier(SSLSocketFactory.ALLOW_ALL_HOSTNAME_VERIFIER);
connManager = new PoolingClientConnectionManager();
connManager.setMaxTotal(100);
connManager.setDefaultMaxPerRoute(100);
connManager.getSchemeRegistry().register(new Scheme("https", 443,
socketFactory));
params = new BasicHttpParams();
params.setParameter(CoreConnectionPNames.CONNECTION_TIMEOUT,5000);
params.setParameter(CoreConnectionPNames.SO_TIMEOUT, 5000);
httpClient = new DefaultHttpClient(connManager, params);
and do the post request with the following method:
private String doPost(String url, String payload) {
HttpPost httpPost = null;
String result = null;
HttpResponse response = null;
try {
httpPost = new HttpPost(url);
StringEntity postEntity = new StringEntity(payload);
httpPost.setEntity(postEntity);
httpPost.addHeader("Content-Type", "application/json");
httpPost.addHeader("Authorization", "Basic " + this.authString);
response = this.httpClient.execute(httpPost);
result = EntityUtils.toString(response.getEntity());
EntityUtils.consume(response.getEntity());
} catch (Exception e) {
e.printStackTrace();
return null;
}finally {
if(response != null){
if(response.getEntity() != null){
InputStream input;
try {
input = response.getEntity().getContent();
if(input != null){
input.close();
}
} catch (IllegalStateException | IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
}
}
return result;
}
the problem for me is that I want to use the keep-alive ability of
PoolingClientConnectionManager, but the httpclient close the connection after
the single post request. the debug log as follow. Who konws
what's wrong? Is it the bug of the httpclient ? or I have done something
wrong with my code?
