本文介绍了为什么我会得到Android：目标服务器无法响应？的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
API链接： http://www.familybuds.com/storegrunt-new/api_home/validate_step_one/platform/1
POST参数： store_name =abc代码在GoDaddy服务器上
POST parameter : store_name = "abc" the code is on GoDaddy Server
这个api是工作正常到5月25日，但突然它从Android应用程序从26日早上停止工作。同样的api在iPhone APP上运行正常。
This api was working fine till 25July, but suddenly it stopped working from 26th morning on Android APP. The same api is working fine on iPhone APP.
Android代码：
HttpParams httpParameters = new BasicHttpParams();
HttpConnectionParams.setConnectionTimeout(httpParameters, 10000);
HttpConnectionParams.setSoTimeout(httpParameters, 10000+12000);
DefaultHttpClient client = new DefaultHttpClient(httpParameters);
HttpPost httppost = new HttpPost(url);
HttpResponse response;
httppost.setEntity(new UrlEncodedFormEntity(nameValuePairs));
client.addRequestInterceptor(new HttpRequestInterceptor() {
@Override
public void process(HttpRequest request, HttpContext context)
throws HttpException, IOException {
// TODO Auto-generated method stub
if (!request.containsHeader("Accept-Encoding")) {
request.addHeader("Accept-Encoding", "gzip");
}
}
});
client.addResponseInterceptor(new HttpResponseInterceptor() {
public void process(
final HttpResponse response,
final HttpContext context) throws HttpException, IOException {
HttpEntity entity = response.getEntity();
if (entity != null) {
Header ceheader = entity.getContentEncoding();
if (ceheader != null) {
HeaderElement[] codecs = ceheader.getElements();
for (int i = 0; i < codecs.length; i++) {
if (codecs[i].getName().equalsIgnoreCase("gzip")) {
response.setEntity(
new GzipDecompressingEntity(response.getEntity()));
return;
}
}
}
}
}
});
// Log.d(TAG, "Executing request: "+ methodToString(mMethod) +": "+ mUri.toString());
response = client.execute(httppost);
Android的堆栈跟踪（日志）：

尝试过以下解决方案： Https connectio n Android 但没有运气..
Have tried out solution from : Https connection Android but with no luck..
我尝试在Amazon EC2服务器上放置相同的服务器代码..而且API与Android和iPhone APP配合得很好。
I tried putting the same server code on Amazon EC2 Server.. and API worked fine with android and iPhone APP.
任何人都可以提供帮助，这可能是导致Android应用突然无法与GoDaddy服务器（API）通信的原因
Can anyone help, what may be the reason for sudden non-working of Android app for communicating with server(API) on GoDaddy
推荐答案
HttpParams httpParameters = new BasicHttpParams();
HttpConnectionParams.setConnectionTimeout(httpParameters, 10000);
HttpConnectionParams.setSoTimeout(httpParameters, 10000+12000);
DefaultHttpClient client = new DefaultHttpClient(httpParameters);
HttpPost httppost = new HttpPost(url);
尝试使用此代码替换上面的代码
HttpParams httpParameters = new BasicHttpParams();
HttpConnectionParams.setConnectionTimeout(httpParameters, 10000);
HttpConnectionParams.setSoTimeout(httpParameters, 10000+12000);
DefaultHttpClient client = new DefaultHttpClient();
HttpPost httppost = new HttpPost(url);
httpost.setParams(httpParameters);
此解决方案对我有用....
