【问题描述】：

我目前遇到关于 asynchttpclient 发布请求的问题。我能够使用 loopj 的 asynchttpclient 执行获取请求，但我遇到了关于发布请求的问题。

这是我发帖请求的代码。

 AsyncHttpClient client = new AsyncHttpClient();
                RequestParams params = new RequestParams();
                params.put("username", username);
                params.put("password", password);

            client.post("http://localhost/lin/mobile_login/", params, new AsyncHttpResponseHandler() {
                @Override
                public void onSuccess(int statusCode, Header[] headers, byte[] responseBody) {
                    String response = new String(responseBody);
                    Log.d("RAW", String.valueOf(responseBody));
                    Log.d("RESPONSE",response);
                }

                @Override
                public void onFailure(int statusCode, Header[] headers, byte[] responseBody, Throwable error) {
                    String err = new String(responseBody);
                    Log.d("ERROR", err);
                    Log.d("EXCE", String.valueOf(error));
                }
            });

它会抛出

我试图将 2 参数传递给我的发布请求。希望你能帮助我解决我的问题。

【解决方案1】：

问题在于您的网址http://localhost/lin/mobile_login/

Url 中不能包含 localhost。您必须在此处添加 IP 地址，而不是 localhost，例如 http://192.168.42.37/lin/mobile_login/，而 192.168.42.37 将是 IP 地址。您需要先找到 IP 地址。还要确保服务器和手机在同一个网络上。
