一、在build.gradle文件里添加
implementation 'com.squareup.okhttp3:okhttp:4.9.0'
implementation 'com.squareup.okhttp3:okhttp:3.12.0'
implementation 'com.squareup.okio:okio:1.17.4'
implementation 'com.lzy.net:okgo:3.0.4'
implementation 'com.alibaba:fastjson:1.2.57'
implementation 'com.orhanobut:logger:2.2.0'
com.alibaba:fastjson:用于JSON解析,
com.orhanobut:logger:用于输出日志
二、在AndroidManifest.xml里添加
//支持网络请求
<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
//其他
<uses-permission android:name="android.permission.KILL_BACKGROUND_PROCESSES" /> <uses-permission android:name="android.permission.READ_SMS" /> <uses-permission android:name="android.permission.READ_CONTACTS" /> <uses-permission android:name="android.permission.WRITE_CONTACTS" /> <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" /> <uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" />
<applicationandroid:name=".App"android:allowBackup="true"android:icon="@mipmap/cookie"android:label="手机端测试"android:roundIcon="@mipmap/ic_launcher_round"android:supportsRtl="true"android:theme="@style/Theme.Drysister"android:usesCleartextTraffic="true">
//在App里初始化okgo
android:name=".App"
//不安全请求的限制级别,降低安全级别
//参考:解决:qemu_pipe_open_ns:62: Could not connect to the ‘pipe:qemud:network‘ service: Invalid argument 202_qemu_pipe_open_ns:62: could not connect to the 'pi-CSDN博客
android:usesCleartextTraffic="true"
三、新建App,初始化okgo、Logger
public class App extends Application {private static App mInstance;public static App getInstance(){if(mInstance==null){mInstance=new App();}return mInstance;}@Overridepublic void onCreate(){super.onCreate();mInstance = this; OkGo.getInstance().init(this).setOkHttpClient(new OkHttpClient.Builder().readTimeout(10000L, TimeUnit.MILLISECONDS).writeTimeout(10000L, TimeUnit.MILLISECONDS).connectTimeout(10000L, TimeUnit.MILLISECONDS).build()).setCacheTime(CacheEntity.CACHE_NEVER_EXPIRE) //全局统一缓存时间,默认永不过期,可以不传.setRetryCount(3) //全局统一超时重连次数,默认为三次,// 那么最差的情况会请求4次(一次原始请求,三次重连请求),不需要可以设置为0.setCacheMode(CacheMode.NO_CACHE).setCacheTime(-1L);//日志格式化FormatStrategy formatStrategy = PrettyFormatStrategy.newBuilder().showThreadInfo(false) // 是否显示线程信息 默认显示 上图Thread Infrom的位置.methodCount(1) // 展示方法的行数 默认是2 上图Method的行数.methodOffset(0) // 内部方法调用向上偏移的行数 默认是0//.logStrategy(customLog) // 改变log打印的策略一种是写本地,一种是logcat显示 默认是后者(当然也可以自己定义).tag("DCSYT") // 自定义全局tag 默认:PRETTY_LOGGER.build();//在Application中初始化一下Logger.addLogAdapter(new AndroidLogAdapter(formatStrategy));Logger.addLogAdapter(new DiskLogAdapter(){@Overridepublic boolean isLoggable(int priority, @Nullable String tag) {return BuildConfig.DEBUG;}});// Logger.d("Start APP");}}
四、OkGo
Map<String, String> localMap = new HashMap<>();localMap.put("strdt", "2022-11-03 14:04:02");//strdt=2022-11-03 14:04:02List<String> urlparams=new ArrayList<>();List<File> fileparams=new ArrayList<>();List<HttpParams.FileWrapper> filewrappers=new ArrayList<>();String serveurl="https://stqmf.fzdc.cn/home/getTime";// OkGo.<String>get(serveurl )//get<=>post 请求方式.tag(this) // 请求的tag,主要用于取消对应的请求
// .isMultipart(true) //制使用multipart/form-data表单上传
// .isSpliceUrl(true) //制将params的参数拼接到url后面.retryCount(3) // 超时重连次数
// .cacheKey("caceKey") // 设置当前请求的缓存key
// .cacheTime(5000) // 缓存的过期时间,单位毫秒
// .cacheMode(CacheMode.DEFAULT) // 缓存模式,详细请看第四部分,缓存介绍
// .headers("header1","headervalue1") // 添鞏玗禧弓罩谨加请求头参数.params(localMap) // 添加请求参数
// .addUrlParams("key",urlparams)
// .addFileParams("key",fileparams)
// .addFileWrapperParams("key",filewrappers).execute(new StringCallback() {@Overridepublic void onSuccess(Response<String> response) {Logger.d("OkGo...onSuccess," + response.code() + "-" + response.body());UserDto obj= JSON.parseObject(response.body().toString(),UserDto.class);Logger.d(obj.data);}@Overridepublic void onError(Response<String> response) {Logger.d("OkGo...onError," + response.code() + "-" + response.body());}});
五、OkHttpClient
//1.构建OkHttpClient实例final OkHttpClient okHttpClient = new OkHttpClient.Builder().connectTimeout(200, TimeUnit.SECONDS)//链接超时为2秒,单位为秒.writeTimeout(200, TimeUnit.SECONDS)//写入超时.readTimeout(200, TimeUnit.SECONDS)//读取超时.build();//创建线程,在子线程中运行new Thread(new Runnable() {@Overridepublic void run() {try {//1、异步get...//通过Builder辅助类构建Request对象,链式编程String url="https://stqmf.fzdc.cn/home/getTime";HttpUrl.Builder httpBuilder = HttpUrl.parse(url).newBuilder();httpBuilder.addQueryParameter("strdt","2022-11-04 0:04:02");Request request = new Request.Builder().url(httpBuilder.build()).get().build();//异步okHttpClient.newCall(request).enqueue(new Callback() {@Overridepublic void onFailure(@NotNull Call call, @NotNull IOException e) {e.printStackTrace();Logger.e("get异步响应失败==" + e.toString());}@Overridepublic void onResponse(@NotNull Call call, @NotNull okhttp3.Response response) throws IOException {String result = response.body().string();Logger.e("get异步响应成功==" + result);UserDto obj=JSON.parseObject(result,UserDto.class);Logger.e(obj.data);}});//2、同步GET // Request request = new Request.Builder() // .get()//get请求 // .url("https://stqmf.fzdc.cn/home/getTime")//请求地址 // .build();//构建 // //通过mOkHttpClient调用请求得到Call // final Call call = okHttpClient.newCall(request); // //执行同步请求,获取Response对象 // okhttp3.Response response = call.execute(); // // if (response.isSuccessful()) {//如果请求成功 // String string = response.body().string(); // Logger.e("get同步请求success==" + string); // //响应体的string()对于小文档来说十分方便高效,但是如果响应体太大(超过1M),应避免使用string()方法, // //因为它会把整个文档加载到内存中,对用超多1M的响应body,应该使用流的方式来处理。 // // //response.body().bytes();//字节数组类型 // //response.body().byteStream();//字节流类型 // //response.body().charStream();//字符流类型 // // } else { // Logger.e("get同步请求failure=="); // }//3、同步POST... // //提交键值对需要用到FormBody,FormBody继承自RequestBody // FormBody formBody = new FormBody.Builder() // //添加键值对(通多Key-value的形式添加键值对参数) // .add("key", "value") // .build(); // // final Request request = new Request.Builder() // .post(formBody) // .url("https://stqmf.fzdc.cn/home/getTime")//URL地址 // .build(); // // okhttp3.Response response = okHttpClient.newCall(request).execute(); // if (response.isSuccessful()) { // Logger.e("Post请求String同步响应success==" + response.body().string()); // } else { // Logger.e("Post请求String同步响应failure==" + response.body().string()); // }//4、异步POST... // okHttpClient.newCall(request).enqueue(new Callback() { // @Override // public void onFailure(@NotNull Call call, @NotNull IOException e) { // Logger.e("Post请求(键值对)异步响应failure==" + e.getMessage()); // } // // @Override // public void onResponse(@NotNull Call call, @NotNull okhttp3.Response response) throws IOException { // String result = response.body().string(); // Logger.e("Post请求(键值对)异步响应Success==" + result); // } // });} catch (Exception e) {Logger.e("请求IOException==" + e.toString());}}}).start();
