有选择地将不记名令牌添加到改造中的标头 [英] Add bearer token selectively to header in Retrofit

问题描述

我想知道是否有任何选项可以根据 Retrofit 中的标志或注释启用/禁用标头拦截器.由于我的 API 中很少有不需要令牌的路径，因此我需要跳过向这些 API 调用添加令牌的步骤.

I would like to know if there is any option to enable/disable header Interceptor based on a flag or annotation in Retrofit. Since there are few paths in my API that do not need a token, I need to skip adding token to those API calls.

目前我有一个简单的拦截器，它将向我的应用程序发出的所有请求添加一个标头

Currently I have a simple Interceptor which will add a header to all the requests that are made from my application

//builder is of type OkHttpClient.Builder
builder.addInterceptor(chain -> {
    Request request = chain.request().newBuilder().
    addHeader("authorization", "Bearer foofootoken").build();

    return chain.proceed(request);
});

推荐答案

我前段时间研究过这个问题，我没有找到任何开箱即用的改造提供的解决方案，但您可以轻松地自己实现一个解决方法.

I have researched this some time ago and I didn't find any solution provided by retrofit out of the box, but you can easily implement a workaround by yourself.

只需使用您选择的标头对请求进行注释，例如NoAuth: true"并在拦截器中检查此标头:

Just annotate the request with a header of your choosing, for example "NoAuth: true" and check for this header in the interceptor:

builder.addInterceptor(chain -> {
    String noAuthHeader = chain.request().header("NoAuth");
    Request.Builder request = chain.request().newBuilder();
    if(noAuthHeader == null || !noAuthHeader.equals("true")){
        request.addHeader("authorization", "Bearer foofootoken").build();
    }

    return chain.proceed(request.build());
});
