一.原生OKHttp的Get和Post请求
1.OKHttp_GET 请求
class="brush:java;gutter:true;">private String get(String url) throws IOException {
        Request request = new Request.Builder()
                .url(url)
                .build();
        Response response = client.newCall(request).execute();
        return response.body().string();
    }
2.OKHttp_POST 请求
private String post(String url, String json) throws IOException {
        RequestBody body = RequestBody.create(JSON, json);
        Request request = new Request.Builder()
                .url(url)
                .post(body)
                .build();
        Response response = client.newCall(request).execute();
        return response.body().string();
    }
二.第三方封装好的OKHttp库-okhttp-utils
