我正在尝试连接以进行身份验证并连接到安全服务器，但它失败并敬酒到 Throwable t。这是我的http连接代码
// Log.i(getClass().getSimpleName(), "send task - start");
HttpParams httpParams = new BasicHttpParams();
HttpConnectionParams.setConnectionTimeout(httpParams,
15000);
HttpConnectionParams.setSoTimeout(httpParams, 15000);
//
HttpParams p = new BasicHttpParams();
// p.setParameter("name", pvo.getName());
p.setParameter("user", "1");
// Instantiate an HttpClient
HttpClient httpclient = new DefaultHttpClient(p);
UsernamePasswordCredentials credentials = new UsernamePasswordCredentials(":jeunes-caisse-depargne", "HREwFdin3r6Y");
((AbstractHttpClient) httpclient).getCredentialsProvider().setCredentials( new AuthScope(AuthScope.ANY_HOST, AuthScope.ANY_PORT), credentials);
String url = "http://www.1.json";
HttpPost httppost = new HttpPost(url);
// Instantiate a GET HTTP method
try {
Log.i(getClass().getSimpleName(), "send task - start");
//
List<NameValuePair> nameValuePairs = new ArrayList<NameValuePair>(
2);
nameValuePairs.add(new BasicNameValuePair("user", "1"));
httppost.setEntity(new UrlEncodedFormEntity(nameValuePairs));
ResponseHandler<String> responseHandler = new BasicResponseHandler();
String responseBody = httpclient.execute(httppost,
responseHandler);
// Parse
JSONObject json = new JSONObject(responseBody);
JSONArray jArray = json.getJSONArray("posts");
ArrayList<HashMap<String, String>> mylist =
new ArrayList<HashMap<String, String>>();
for (int i = 0; i < jArray.length(); i++) {
HashMap<String, String> map = new HashMap<String, String>();
JSONObject e = jArray.getJSONObject(i);
String s = e.getString("post");
JSONObject jObject = new JSONObject(s);
map.put("UserName", jObject.getString("xxxxx"));
map.put("FullName", jObject.getString("xxxxxx"));
mylist.add(map);
}
Toast.makeText(this, responseBody, Toast.LENGTH_LONG).show();
} catch (ClientProtocolException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
// Log.i(getClass().getSimpleName(), "send task - end");
catch (Throwable t) {
Toast.makeText(this, "Request failed: " + t.toString(),
Toast.LENGTH_LONG).show();
}
更新：从 chintan-khetiya 回答我这样做了，但我收到了日志警告
HttpClient client = new DefaultHttpClient();
HttpConnectionParams.setConnectionTimeout(client.getParams(), 10000); //Timeout Limit
HttpResponse response;
JSONObject json = new JSONObject();
try {
HttpPost post = new HttpPost("depargne.fr....");
json.put("user_name", "xxxx");
json.put("password", "xxx");
StringEntity se = new StringEntity( json.toString());
se.setContentType(new BasicHeader(HTTP.CONTENT_TYPE, "application/json"));
post.setEntity(se);
response = client.execute(post);
/*Checking response */
if(response!=null){
is = response.getEntity().getContent(); //Get the data in the entity
}
try
{
BufferedReader reader = new BufferedReader(new InputStreamReader(is, "iso-8859-1"), 8);
StringBuilder sb = new StringBuilder();
String line = null;
while ((line = reader.readLine()) != null)
{
sb.append(line + "\n");
}
is.close();
result = sb.toString();
System.out.println("Result: "+result);
}
catch (Exception e)
{
Log.e("Loading Runnable Error converting result :", e.toString());
}
} catch(Exception e) {
e.printStackTrace();
//createDialog("Error", "Cannot Estabilish Connection");
}

我换了
HttpParams httpParams = new BasicHttpParams();
HttpConnectionParams.setConnectionTimeout(httpParams,
15000);
HttpConnectionParams.setSoTimeout(httpParams, 15000);
和
DefaultHttpClient client = new DefaultHttpClient();
client.getCredentialsProvider().setCredentials(AuthScope.ANY, new UsernamePasswordCredentials("user1", "user1"));
client.addRequestInterceptor(new HttpRequestInterceptor() {
public void process(HttpRequest request, HttpContext context) throws HttpException, IOException {
AuthState state = (AuthState) context.getAttribute(ClientContext.TARGET_AUTH_STATE);
if (state.getAuthScheme() == null) {
BasicScheme scheme = new BasicScheme();
CredentialsProvider credentialsProvider = (CredentialsProvider) context.getAttribute(ClientContext.CREDS_PROVIDER);
org.apache.http.auth.Credentials credentials = credentialsProvider.getCredentials(AuthScope.ANY);
if (credentials == null) {
throw new HttpException();
}
state.setAuthScope(AuthScope.ANY);
state.setAuthScheme(scheme);
state.setCredentials(credentials);
}
}
}, 0); // 0 = first, and you really want to be first.
但是警告错误仍然发生并且仍然没有响应。
