在Android的OKhttp中通过POST请求发送JSON正文

试试这个

添加Gradle取决于

compile 'com.squareup.okhttp3:okhttp:3.2.0'

public static JSonObject foo(String url, JSonObject json) {        JSonObject jsonObjectResp = null;        try { MediaType JSON = MediaType.parse("application/json; charset=utf-8"); OkHttpClient client = new OkHttpClient(); okhttp3.RequestBody body = RequestBody.create(JSON, json.toString()); okhttp3.Request request = new okhttp3.Request.Builder()         .url(url)         .post(body)         .build(); okhttp3.Response response = client.newCall(request).execute(); String networkResp = response.body().string(); if (!networkResp.isEmpty()) {     jsonObjectResp = parseJSonStringToJSONObject(networkResp); }        } catch (Exception ex) { String err = String.format("{"result":"false","error":"%s"}", ex.getMessage()); jsonObjectResp = parseJSonStringToJSONObject(err);        }        return jsonObjectResp;    }

解析响应

   private static JSonObject parseJSonStringToJSONObject(final String strr) {    JSonObject response = null;    try {        response = new JSonObject(strr);    } catch (Exception ex) {        //  Log.e("Could not parse malformed JSON: "" + json + """);        try { response = new JSonObject(); response.put("result", "failed"); response.put("data", strr); response.put("error", ex.getMessage());        } catch (Exception exx) {        }    }    return response;}
