如何防止改装自动跟随302 [英] How do you prevent Retrofit from automatically following a 302

问题描述

我正在尝试使用Android上的Retrofit进行身份验证.该呼叫将302返回到成功或失败页面.原始的302响应会带回用于维持成功身份验证所需的会话cookie，但是Retrofit会在我有机会使用该cookie之前自动将请求移交给重定向网址.

I have an authentication call that i'm trying to make using Retrofit on Android. The call returns a 302 to either a success or failure page. The original 302 response brings back a session cookie needed to maintain authentication on success, however Retrofit is automatically handing the request off to the redirect url before I get a chance to consume the cookie.

是否有一种方法可以防止遵循重定向?还是有办法在Retrofit上编写一个响应处理程序，该处理程序可以在进行第二次调用之前添加适当的标头?

Is there a way to prevent following the redirect? Or is there a way to write a response handler on Retrofit that can add the appropriate header before making the second call?

推荐答案

为防止重定向，您必须配置客户端，例如，使用OkHttp 2:

to prevent the redirect you have to configure your client, e.g with OkHttp 2:

private sendRequest() {
    OkHttpClient client = new OkHttpClient();
    client.setFollowRedirects(false);

    connectAdapter = new RestAdapter.Builder()
            .setClient(new OkClient(client))
            .setEndpoint("http://yourendpoint")
            .setLogLevel(RestAdapter.LogLevel.FULL)
            .build();

    connectAdapter.create(YourRequest.class).sendMyRequest("login","password");

}

使用OKHTTP 3(您可以从@gropapa阅读此答案):

With OKHTTP 3 (you can read this answer from @gropapa):

OkHttpClient.Builder builder = new OkHttpClient.Builder();
builder.followRedirects(false);
OkHttpClient httpClient = builder.build();
