今天踩过的大坑........

这是一段使用okhttp进行post请求的代码

 OkHttpClient client = new OkHttpClient();
        RequestBody body = new FormEncodingBuilder()
                .add("key", value)
                .build();
        Request request = new Request.Builder()
                .url(urlstr)
                .post(body)
                .build();
        client.newCall(request).enqueue(new Callback() {
            @Override
            public void onFailure(Request request, IOException e) {

            }
            @Override
            public void onResponse(Response response) throws IOException {
                final String res = response.body().string();
                new Thread(new Runnable() {
                    @Override
                    public void run() {
                        Log.d("response", res);
                    }
                }).start();
            }
        });

运行结果返回的是com.squareup.okhttp.internal.http.RealResponseBody@52858c28这段字符串，一脸懵逼，本来应该是返回一段json字符串的。

解决方法：

Replace

String json = response.body().toString();

with

String json = response.body().string();

改了之后运行一下就出来了：

{"code":1,"msg":"成功","result":"201607121644019558"}
