Question

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

这个api工作正常到7月25日，但突然间它从26日早上在Android APP上停止工作。同样的api在iPhone APP上工作正常。

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);

从Https connection Android尝试过解决方案，但没有运气..

我尝试在Amazon EC2 Server上安装相同的服务器代码..并且API与Android和iPhone APP配合良好。

任何人都可以提供帮助，这可能是导致Android应用突然无法在GoDaddy上与服务器（API）进行通信的原因

Answer 1

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

替换上述代码

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);

这个解决方案对我有用......

为什么我会得到Android：目标服务器无法响应？
