如何从响应改造中获取cookie，okhttp？

Question

我正在尝试通过API响应从API响应中检索Cookies值，以在后端关闭的情况下通过将cookie值设置为新的API调用来维护后端会话：

[

RetrofitClient.java

public static Retrofit getClient() {

    if (checkClient()) {
        return getRetrofit();
    }

    HttpLoggingInterceptor interceptor = new HttpLoggingInterceptor();
    interceptor.setLevel(HttpLoggingInterceptor.Level.BODY);
    CookieHandler cookieHandler = new CookieManager();

    okhttp3.OkHttpClient client = new okhttp3.OkHttpClient.Builder().addNetworkInterceptor(interceptor)
            .cookieJar(new JavaNetCookieJar(cookieHandler))
            .connectTimeout(10, TimeUnit.SECONDS)
            .writeTimeout(10, TimeUnit.SECONDS)
            .readTimeout(30, TimeUnit.SECONDS)
            .build();

    Gson gson = new GsonBuilder()
            .setLenient()
            .create();

    retrofit = new Retrofit.Builder()
            .baseUrl(BASE_URL)
            .addConverterFactory(GsonConverterFactory.create(gson))
            .client(client)
            .build();
    return retrofit;
}

API调用

private void userLogin(String username, String password) {
    Retrofit retrofit = RetrofitClient.getClient();

    final LoginServices loginServices = retrofit.create(LoginServices.class);
    Call<LoginResponse> call = loginServices.userLogin(username, password);

    call.enqueue(new Callback<LoginResponse>() {
        @Override
        public void onResponse(Call<LoginResponse> call, Response<LoginResponse> response) {
            Log.d("Response code:", "===========" + response.code());

            Log.d("==Cookie==1===", "==="+response.raw().request().headers().get("Cookie"));
            Log.d("==Cookie==2==", "==="+response.headers().get("Cookie"));
            Log.d("==Content-Type====", "==="+response.headers().get("Content-Type"));

        }

        @Override
        public void onFailure(Call<LoginResponse> call, Throwable t) {
            Log.e("TAG", "=======onFailure: " + t.toString());
            t.printStackTrace();
            // Log error here since request failed
        }
    });
}

Logcat：

Response code:: ===========200
==Cookie==1===: ===null
==Cookie==1===: ===null
==Content-Type====: ===application/json

我还尝试了其他不适用于我的其他方法。请帮助！

Answer 1

标题名称是“ Set-Cookie”而不是“ Cookie”]

您采用的方法不正确。如果要保存Cookie，则可以创建一个拦截器并保存Cookie，并在以后随时使用时使用。

Answer 2

List<String> Cookielist = response.headers().values("Set-Cookie");
String jsessionid = (Cookielist .get(0).split(";"))[0];

Answer 3

尝试response.headers().get("Set-Cookie"))
