1、使用okHttp3登录

2、Md5密码加密

3、完整代码

4、项目案例

使用okHttp3登录：

使用okHttp3之前要在build.gradle引入okHttp3的依赖（顺便引入解析数据的gson）

implementation 'com.squareup.okhttp3:okhttp:3.4.1' //okhttp3
    implementation 'com.google.code.gson:gson:2.7' //导入gson

在AndroidManifest.xml中加入网络请求权限

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

我在这里封装好了okHttp3的登录类：

package com.example.login;
    
    import android.util.Log;
    import android.widget.Toast;
    
    import org.json.JSONException;
    import org.json.JSONObject;
    import okhttp3.MediaType;
    import okhttp3.OkHttpClient;
    import okhttp3.Request;
    import okhttp3.RequestBody;
    
    public class OkHttp {
        private static MediaType mediaType;
    
        //登录
        public static void Login(String url,String number,String password,okhttp3.Callback callback){
            try {
                OkHttpClient client = new OkHttpClient();
                JSONObject jsonObject =new JSONObject();
                jsonObject.put("number",number.toString());
                jsonObject.put("password",password.toString());
                mediaType = MediaType.parse("application/json;charset=utf-8");
                RequestBody requestBody = RequestBody.create(mediaType,jsonObject.toString());
                Request request = new Request.Builder().url(url).post(requestBody).build();
                client.newCall(request).enqueue(callback);
            } catch (JSONException e) {
                e.printStackTrace();
            }
        }
    }

然后使用（在线程中使用）：

String number = edt_number.getText().toString(); //获取文本框输入的账号
    String password = edt_number.getText().toString(); //获取文本框输入的密码
    String url = "http://XXX/login"; //获取url，这里加上自己的登录url
    OkHttp.Login(url,number,password, new okhttp3.Callback() {
        @Override
        public void onFailure(Call call, IOException e) {
            Log.d("失败","错误");
        }
    
         @Override
         public void onResponse(Call call, final Response response) throws IOException {
            if(response.code() == 200){
            Gson gson = new Gson();
            String data = response.body().string();
            final Emp emp = gson.fromJson(data,Emp.class); //新加了一个人员类
            Log.d("成功","姓名：" + emp.getName());
            runOnUiThread(new Runnable() {
                   @Override
                   public void run() {
                          btn_login.setText(emp.getName());
                   }
             });
             }else{
                    Log.d("成功","获取失败");
              }
          }
    });

Md5密码加密（两种加密，看个人需求，普通Md5加密、自定义Md5加密）：

Md5加密(代码)：

public String md5Decode(String content) {
            byte[] hash;
            try {
                hash = MessageDigest.getInstance("MD5").digest(content.getBytes("UTF-8"));
            } catch (NoSuchAlgorithmException e) {
                throw new RuntimeException("NoSuchAlgorithmException", e);
            } catch (UnsupportedEncodingException e) {
                throw new RuntimeException("UnsupportedEncodingException", e);
            }
            //对生成的16字节数组进行补零操作
            StringBuilder hex = new StringBuilder(hash.length * 2);
            for (byte b : hash) {
                if ((b & 0xFF) < 0x10) {
                    hex.append("0");
                }
                hex.append(Integer.toHexString(b & 0xFF));
            }
            return hex.toString();
        }

普通加密使用（直接在获取文本框密码中加密）：

String password = md5Decode(edt_password.getText().toString()); //加密 //获取文本框输入的密码

自定义加密使用（在后面加了一段乱码，后台中的加密同时也要加上这段乱码）：

String password = md5Decode(edt_password.getText().toString() +"dabsdafaqj23ou89ZXcj@#$@#$#@KJdjklj;D../dSF.,");

    <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
        xmlns:app="http://schemas.android.com/apk/res-auto"
        xmlns:tools="http://schemas.android.com/tools"

        <Button
            android:id="@+id/btn_login"
            android:layout_width="match_parent"

            android:text="登录"/>
    
    </LinearLayout>

OkHttp封装类代码：

Emp人员类：

package com.example.login;
    
    public class Emp {
        private String number;
        private String name;
        public Emp(String number,String name){
            this.number = number;
            this.name = name;
        }
    
        public String getNumber() {
            return number;
        }
    
        public void setNumber(String number) {
            this.number = number;
        }
    
        public String getName() {
            return name;
        }
    
        public void setName(String name) {
            this.name = name;
        }
    }
