android okhttp3自动保存cookie（二）

一、在build加入依赖

implementation 'com.squareup.okhttp3:okhttp:3.6.0' implementation 'com.squareup.okio:okio:1.5.0' implementation 'com.github.franmontiel:PersistentCookieJar:v1.0.1'

二、写网络请求工具类

import com.example.mowangtao.MVP.BaseApplication; import com.franmontiel.persistentcookiejar.PersistentCookieJar; import com.franmontiel.persistentcookiejar.cache.SetCookieCache; import com.franmontiel.persistentcookiejar.persistence.SharedPrefsCookiePersistor; import com.google.gson.Gson; import java.io.IOException; import java.io.UnsupportedEncodingException; import java.util.HashMap; import java.util.concurrent.TimeUnit; import okhttp3.Call; import okhttp3.Callback; import okhttp3.MediaType; import okhttp3.OkHttpClient; import okhttp3.Request; import okhttp3.RequestBody; import okhttp3.Response; public class RequestManager { private OkHttpClient mOkHttpClient; private static String BASE_URL = Constant.ServerletUrl; private static RequestManager instance; private Gson gson; public RequestManager() { PersistentCookieJar cookieJar = new PersistentCookieJar(new SetCookieCache(), new SharedPrefsCookiePersistor(BaseApplication.getInstance().getBaseContext())); mOkHttpClient = new OkHttpClient.Builder() .connectTimeout(10000, TimeUnit.MILLISECONDS) .readTimeout(10000, TimeUnit.MILLISECONDS) .cookieJar(cookieJar) .build(); } public static RequestManager getInstance() { if (instance == null) { synchronized (RequestManager.class) { if (instance == null) { instance = new RequestManager(); } } } return instance; } /*** * post请求 */ public void PostRequest(HashMap<String, Object> paramsMap, String url, final ResultCallback callback) throws UnsupportedEncodingException { gson = new Gson(); String params = gson.toJson(paramsMap); RequestBody body = RequestBody.create(MediaType.parse("application/json;charset=UTF-8"), params); String requestUrl = BASE_URL + url; final Request request = new Request.Builder() .url(requestUrl) .post(body) .build(); Call callclient = mOkHttpClient.newCall(request); callclient.enqueue(new Callback() { @Override public void onFailure(Call call, IOException e) { callback.onError("网络请求失败，请稍后重试"); } @Override public void onResponse(Call call, final Response response) throws IOException { if (response.isSuccessful()) { int code = response.code(); if (code == 200) {//请求成功 String result = response.body().string(); callback.onResponse(String.valueOf(code), result); } else callback.onError(response.message()); } else { callback.onError("网络请求失败，请稍后重试"); } } }); } public interface ResultCallback { void onResponse(String code, String response); void onError(String msg); } }

三、在你需要判断是有获取到cookie地方使用

SharedPrefsCookiePersistor sharedPrefsCookiePersistor = new SharedPrefsCookiePersistor(StartActivity.this); List<Cookie> cookies = sharedPrefsCookiePersistor.loadAll();
