Posted 2021-08-16 彭老希

一、请求参数

参数名称	参数值
Content-Type	application/json

二、Body

名称	类型
name	string
age	string

三、实例展示

		//利用Map接收Body参数
   		Map map = new HashMap();
        map.put("name","彭老希");
        map.put("age","19");
        //通过toJSONString转换成JSON
        String jsonPost = JSON.toJSONString(map);
        DishLog.i("postRequestJson",jsonPost);
        MediaType postrequestjsontype = MediaType.parse("application/json; charset=utf-8");
        //项目中可以封装起来，这里用原生的方式，方便大家阅读
        String url = "请求的post链接";
        OkHttpClient client = new OkHttpClient();
        RequestBody body = RequestBody.create(postrequestjsontype,jsonPost);
        Request request = new Request.Builder()
                .url(url)
                .post(body)
                .build();
        Call call = client.newCall(request);
        call.enqueue(new Callback() {
            @Override
            public void onFailure(@NotNull Call call, @NotNull IOException e) {
             	//请求失败返回
            }

            @Override
            public void onResponse(@NotNull Call call, @NotNull Response response) throws IOException {
                if (response.isSuccessful()){
                    Log.i("onResponse",response.body().string());
                }
            }
        });
