在Android的OKhttp中通过POST请求发送JSON正文

我已经设置好OkHttpClient并成功将GET请求发送到服务器。而且，我还可以将带有空body标签的POST请求发送到服务器。

现在，我正在尝试将以下JSON对象发送到服务器。

{ "title": "Mr.", "first_name":"Nifras", "last_name": "", "email": "nfil@gmail.com", "contact_number": "75832366", "billing_address": "", "connected_via":"Application" }

为此，我尝试添加OkHttpClient库类，RequestBody但无法将JSON对象作为http

POST请求的主体发送。我尝试通过以下方式构建主体并处理发布请求。

OkHttpClient client = new OkHttpClient();
    RequestBody body = new RequestBody() {
        @Override
        public MediaType contentType() {
            return ApplicationContants.JSON;
        }
        @Override
        public void writeTo(BufferedSink sink) throws IOException {
              // This is the place to add json I thought. But How could i do this
        }
    };
    Request request = new Request.Builder()
            .url(ApplicationContants.BASE_URL + ApplicationContants.CUSTOMER_URL)
            .post(body)
            .build();

通过POST请求将JSON对象发送到服务器的方式是什么。

提前致谢。

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;
}
