An on-line HTTP interface call does not pass the related resolution procedure

Yesterday, the white system because the call external HTTP interface, timeout does not release, resulting in a slow page response, a long time, reported 502 error.

On the Internet to check the next, 502 error is because the service for the customer's request did not get a timely response, query log, found a lot of HTTP interface exception, the page response is also very slow.

Instantly think of shortening the HTTP client call HTTP interface Timeout time, search this blog http://blog.csdn.net/xinying0424/article/details/36006383 thanks

HttpClient 4: Connection timeout: Connection timeout httpclient.getparams (). Setparameter (coreconnectionpnames.connection_timeout,60000);// or Httpconnectionparams.setconnectiontimeout (params,6000); Read timeout: Httpclient.getparams (). Setparameter ( coreconnectionpnames.so_timeout,60000);//or Httpconnectionparams.setsotimeout (params,60000); HttpClient 3: Connection timeout: Httpclient.gethttpconnectionmanager (). Getparams (). Setconnectiontimeout (60000); Read timeout: Httpclient.gethttpconnectionmanager (). Getparams (). Setsotimeout (60000);

Found that I wrote this in the code, but the time is too long to configure

private static Multithreadedhttpconnectionmanager ConnectionManager = null;    private static int connectiontimeout = 2000;t    private static int sockettimeout = 10000;    private static int maxconnectionperhost =;    private static int maxtotalconnections =;    private static HttpClient client;    static {        ConnectionManager = new Multithreadedhttpconnectionmanager ();        Connectionmanager.getparams (). Setconnectiontimeout (connectiontimeout);        Connectionmanager.getparams (). Setsotimeout (sockettimeout);        Connectionmanager.getparams (). Setdefaultmaxconnectionsperhost (maxconnectionperhost);        Connectionmanager.getparams (). Setmaxtotalconnections (maxtotalconnections);        Client = new HttpClient (ConnectionManager);    }

Then I adjusted the Sockettimeout to 2000, the local want to test, the result ...

Java.lang.IllegalArgumentException:host parameter is null call interface error

Checked the next http://wang371134086.iteye.com/blog/1688458 unexpectedly call HTTP interface did not write HTTP.//, plus this paragraph resolution

Problem solving record, thanks for the blog.
