android-实例-网络互交-post get请求（依赖okhttp）
我的实例（仅供参考）
配置
配置1-权限
在AndroidManifest.xml中配置
<uses-permission android:name="android.permission.INTERNET" />
配置2-下载关联相关包插件（记得同步更新操作）
implementation 'com.squareup.okhttp3:okhttp:3.5.0' implementation 'com.squareup.okio:okio:1.11.0' implementation 'com.google.code.gson:gson:2.9.0'
在工程下新建文件夹network（新建类）
HttpClient.java类
import okhttp3.OkHttpClient; public class HttpClient { private OkHttpClient client;//网络请求对象 /** * 私有的构造器 在HttpClient实例化后 创建OkHttpClient对象 * 用于网络的请求 */ private HttpClient(){ client = new OkHttpClient.Builder() .writeTimeout(80, TimeUnit.SECONDS) .connectTimeout(80,TimeUnit.SECONDS) .readTimeout(80,TimeUnit.SECONDS) .build(); } private static class SingleTon{ public static final HttpClient INSTANCE = new HttpClient(); } /** * 获取单例 * @return */ public static HttpClient getInstance(){ return SingleTon.INSTANCE; } /** * 获取OkHttpClient * @return */ public OkHttpClient getClient() { return client; } }HttpCode.java类（实例中几乎没有用，以后备用）
public class HttpCode { public static final String FAILURE = "失败"; public static final String SUCCESS= "成功"; public static final int ERROR = 0;//错误 public static final int HOME = 1;//请求首页的数据 public static final int DETAILS = 2;//请求详情的数据 public static final int SHOP_TYPE = 3;//请求首页推荐分类的数据 public static final int SHOP_LIST = 4;//请求分类商品的数据 public static final int TYPE_NAME = 5;//请求分类列表的数据 public static final int START_PAGE = 1;//起始页数 public static final int RANDOM_PAGE = 3;//随机页数 public static final int PAGE_ROW = 10;//数据条数 public static final String ROW = "row";//请求参数row public static final String PAGE = "page";//请求参数page public static final int DOWN_REFRESH = 101;//刷新 public static final int DOWN_INIT = 102;//初始化界线 public static final int DOWN_MORE = 103;//加载更多 public static final int LOGIN=701; //请求登录 public static final int SYNC_ASMPLE = 1; public static final int SYNC_REGION = 2; public static final int SYNC_ORG = 3; }HttpUtils.java(实用工具类) 本工具就连2方法（post 和get），尽量压缩程序，理解简单。import android.annotation.SuppressLint; import android.content.Context; import android.os.Handler; import android.util.Log; import java.io.IOException; import java.util.Iterator; import java.util.Map; import okhttp3.Call; import okhttp3.Callback; import okhttp3.FormBody; import okhttp3.MediaType; import okhttp3.Request; import okhttp3.RequestBody; import okhttp3.Response; public class HttpUtils { /*POST请求网络数据*/ //=============================================================== /*登录URL: http://101.43.53.57.62248/login2 Content-Type:application/json-patch+json 请求参数（Body JSON） { "username": "fengxian", "password": "123456", "clientId": "Rx-BnCSr2eUHCwR" }*/ public static void HttpPost_LoginAndGetToken(final Handler handler, final int requestCode) { String target = "http://101.43.53.57:62248/login2"; //登录请求 同时获取token码 String username = "fengxian"; String password = "123456"; String clientId = "Rx-BnCSr2eUHCwR"; String jsonBody = String.format("{\"username\":\"%s\",\"password\":\"%s\",\"clientId\":\"%s\"}", username, password, clientId); RequestBody body = RequestBody.create(MediaType.parse("application/json; charset=utf-8"), jsonBody); //获取一个请求对象 Request request = new Request.Builder().url(target).post(body).addHeader("Content-Type", "application/json").build(); HttpClient.getInstance().getClient().newCall(request).enqueue(new Callback() { //请求失败时的回调方法 @Override public void onFailure(Call call, IOException e) { //将错误结果发送给Handler对象，然后由handleMessage()方法处理 Log.e("HttpUtils-HttpPost", "onFailure: 登录-请求Post失败"); handler.obtainMessage(requestCode, e.getMessage()).sendToTarget(); } //请求成功时的回调方法 @Override public void onResponse(Call call, Response response) throws IOException { //将获取的结果发送给Handler对象，然后由handleMessage()方法处理 Log.e("HttpUtils-HttpPost", "onResponse: 登录-请求Post成功"); //Log.e("HttpUtils-HttpPost", "onResponse: "+response.body().string()); handler.obtainMessage(requestCode, response.body().string()).sendToTarget(); } }); } //=============================================================== /** * Get请求网络数据 */ public static void HttpGet_GetItemCurveList(final Handler handler, final int requestCode,final String token ){ /* //拉取曲线数据 登录URL: http://101.43.53.57.62248/ar/curve/mylistall Method：GET 是否鉴权：是（Bearer Token）权限标识：ar:curve:all:list:isused （⽆权限会返回403 并携带 token ="123456789....."; */ String target ="http://101.43.53.57:62248/ar/curve/mylistall"; final Request request = new Request.Builder() .url(target) .addHeader("Authorization", "Bearer " + token) .addHeader("Content-Type", "application/json") .get() .build(); //获取一个请求对象 HttpClient.getInstance().getClient().newCall(request).enqueue(new Callback() { @SuppressLint("LongLogTag") @Override public void onFailure(Call call, IOException e) { //请求失败时的回调方法 //将错误结果发送给Handler对象，然后由handleMessage()方法处理 Log.e("mytest1_HttpUtils-HttpGet", "onFailure: 请求失败"); handler.obtainMessage(HttpCode.ERROR,e.getMessage()).sendToTarget(); } @SuppressLint("LongLogTag") @Override public void onResponse(Call call, Response response) throws IOException { //请求成功时的回调方法 //将获取的结果发送给Handler对象，然后由handleMessage()方法处理 Log.e("mytest1_HttpUtils-HttpGet", "onFailure: 请求成功"); handler.obtainMessage(requestCode,response.body().string()).sendToTarget(); } }); } //=============================================================== }最初需求1-POST（共2个）
程序直接调用HttpUtils类中的HttpPost_LoginAndGetToken方法完成
建议在跳出对话框+线程中使用post请求
HttpUtils.HttpPost_LoginAndGetToken(handler,HANDLER_CODE_HTTP_LOGIN_AND_GETTOKEN); //HANDLER_CODE_HTTP_LOGIN_AND_GETTOKEN 为 handler接收码（自定义）
最终请求的数据在handler中接收处理
private Handler handler = new Handler(new Handler.Callback() { @Override public boolean handleMessage(Message msg) { switch (msg.what){ case HANDLER_CODE_HTTP_LOGIN_AND_GETTOKEN: { //okhttp3登录请求 同时获取token码 ok //接收HttpUtils.HttpPost_LoginAndGetToken()返回的结果 String jsonStr = (String)msg.obj; if( jsonStr.contains("ok") || jsonStr.contains("success")){ Log.e(TAG, "handleMessage: 登录请求 返回结果--成功"); Gson gson = new Gson(); BeanToken beanToken = gson.fromJson(jsonStr,BeanToken.class); token1 = beanToken.getData(); Log.e(TAG, "handleMessage: token1 = " + token1); } else{Log.e(TAG, "handleMessage: 登录请求 返回结果--失败");} break; } //=================================================== default:break; } return false; } });最后获取token码
最初需求2-GET 带token码的请求（共2个）
程序直接调用HttpUtils类中的HttpPost_LoginAndGetToken方法完成
建议在跳出对话框+线程中使用Get请求
HttpUtils.HttpGet_GetItemCurveList(handler, HANDLER_CODE_HTTP_GET_ITEM_CURVE_LIST, token1); //token1参数为需求1-POST所获取//HANDLER_CODE_HTTP_GET_ITEM_CURVE_LIST 为 handler接收码（自定义）最终请求的数据在handler中接收处理，参考最初需求1-POST
