okhttp body raw post android请求

step1:

  implementation 'com.squareup.okhttp3:okhttp:3.8.1'
    implementation 'com.google.code.gson:gson:2.8.0'

step2:

    <uses-permission android:name="android.permission.INTERNET" />

step3:

package com.example.mepositry;


import android.content.Context;
import android.os.Bundle;
import android.os.Handler;
import android.support.v7.app.AppCompatActivity;
import android.util.Log;

import com.google.gson.Gson;

import java.io.IOException;

import okhttp3.Call;
import okhttp3.Callback;
import okhttp3.MediaType;
import okhttp3.OkHttpClient;
import okhttp3.Request;
import okhttp3.RequestBody;
import okhttp3.Response;

public class MainActivity extends AppCompatActivity {
    private String mUrl2 = "http://192.168.0.231:8088/admin/login";

    private Handler mHandler;
    private OkHttpClient mOkHttpClient;
    public static final MediaType JSON
            = MediaType.parse("application/json; charset=utf-8");

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.test);
        mHandler = new Handler();
        mOkHttpClient = new OkHttpClient();
        updateWeatherDataCoordinates();
    }

    public void updateWeatherDataCoordinates() {
        UserSimple userSimple = new UserSimple("admin", "123456");
        Gson gson = new Gson();
        String userJson = gson.toJson(userSimple);
        System.out.println("wrs:" + userJson);
        RequestBody body = RequestBody.create(JSON, userJson);
        Request request = new Request.Builder().url(mUrl2).post(body).build();
        mOkHttpClient.newCall(request).enqueue(new Callback() {
            @Override
            public void onFailure(Call call, IOException e) {
                Log.e("TAG", "onFailure");
            }

            @Override
            public void onResponse(Call call, final Response response) throws IOException {
                final String stringJson = response.body().string();
                Log.e("TAG", "onResponse" + stringJson);
            }
        });
    }
}

step4:

package com.example.mepositry;

public class UserSimple {

    private String username;
    private String password;

    public UserSimple(String username, String password) {
        this.username = username;
        this.password = password;
    }

    public String getUsername() {
        return username;
    }

    public void setUsername(String username) {
        this.username = username;
    }

    public String getPassword() {
        return password;
    }

    public void setPassword(String password) {
        this.password = password;
    }
}
