Request经常都要携带Cookie，上面说过request创建时可以通过header设置参数，Cookie也是参数之一。就像下面这样：

Request request = new Request.Builder()

.url(url)
.header("Cookie", "xxx")
.build();

然后可以从返回的response里得到新的Cookie，你可能得想办法把Cookie保存起来。
但是OkHttp可以不用我们管理Cookie，自动携带，保存和更新Cookie。
方法是在创建OkHttpClient设置管理Cookie的CookieJar

; "复制代码")

private final HashMap<String, List<Cookie>> cookieStore = new HashMap<>();
OkHttpClient okHttpClient = new OkHttpClient.Builder()

.cookieJar(new CookieJar() {
    @Override public void saveFromResponse(HttpUrl httpUrl, List<Cookie> list) {
        cookieStore.put(httpUrl.host(), list);
    }

    @Override public List<Cookie> loadForRequest(HttpUrl httpUrl) {
        List<Cookie> cookies = cookieStore.get(httpUrl.host()); return cookies != null ? cookies : new ArrayList<Cookie>();
    }
})
.build();

; "复制代码")

这样以后发送Request都不用管Cookie这个参数也不用去response获取新Cookie什么的了。还能通过cookieStore获取当前保存的Cookie。

服务器使用shiro做登录校验及权限验证的时候,app端访问时就要带上cookie，不然请求会提示未登录

private void postAsynHttp() {

    mOkHttpClient=new OkHttpClient.Builder()  
            .cookieJar(new CookieJar() { private final HashMap<HttpUrl, List<Cookie>> cookieStore = new HashMap<>();  

                @Override public void saveFromResponse(HttpUrl url, List<Cookie> cookies) {  
                    cookieStore.put(url, cookies);  
                    cookieStore.put(HttpUrl.parse("http://192.168.31.231:8080/shiro-2"), cookies); for(Cookie cookie:cookies){  
                        System.out.println("cookie Name:"+cookie.name());  
                        System.out.println("cookie Path:"+cookie.path());  
                    }  
                }  

                @Override public List<Cookie> loadForRequest(HttpUrl url) {  
                    List<Cookie> cookies = cookieStore.get(HttpUrl.parse("http://192.168.31.231:8080/shiro-2")); if(cookies==null){  
                        System.out.println("没加载到cookie");  
                    } return cookies != null ? cookies : new ArrayList<Cookie>();  
                }  
            })  
            .build();  
    RequestBody formBody = new FormBody.Builder()  
            .add("username", "admin")  
            .add("password", "admin")  
            .build();  
    final Request request = new Request.Builder()  
            .url("http://192.168.31.231:8080/shiro-2/shiro-login")  
            .post(formBody)  
            .build();  
    Call call = mOkHttpClient.newCall(request);  
    call.enqueue(new Callback() {  
        @Override public void onFailure(Call call, IOException e) {  

        }  

        @Override public void onResponse(Call call, Response response) throws IOException {  
            String str = response.body().string();  
            Log.i("wangshu", str);  

            runOnUiThread(new Runnable() {  
                @Override public void run() {  
                    showProgress(false);  
                    Toast.makeText(getApplicationContext(), "请求成功", Toast.LENGTH_SHORT).show();  
                }  
            });  
        }  

    });  
}
