Retrofit2授权-访问令牌的全局拦截器 [英] Retrofit2 Authorization - Global Interceptor for access token

问题描述

我正在尝试使用Retrofit2， 我想像这样将Token添加到我的Header中:

I'm trying to use Retrofit2, I want to add Token to my Header Like this:

Authorization: Bearer Token 但是下面的code无效:

public interface APIService {
    @Headers({"Authorization", "Bearer "+ token})
    @GET("api/Profiles/GetProfile?id={id}")
    Call<UserProfile> getUser(@Path("id") String id);
}

我的服务器是asp.net webApi.请帮我该怎么办?

推荐答案

您有两种选择-您可以将其添加为调用的参数-

You have two choices -- you can add it as a parameter to your call --

@GET("api/Profiles/GetProfile?id={id}")
Call<UserProfile> getUser(@Path("id") String id, @Header("Authorization") String authHeader);

这可能有点烦人，因为您必须在每次通话时都传入"Bearer" + token.如果您没有太多需要令牌的呼叫，则此方法很合适.

This can be a bit annoying because you will have to pass in the "Bearer" + token on each call. This is suitable if you don't have very many calls that require the token.

如果要将标头添加到所有请求，则可以使用okhttp拦截器-

If you want to add the header to all requests, you can use an okhttp interceptor --

OkHttpClient client = new OkHttpClient.Builder().addInterceptor(new Interceptor() {
      @Override
      public Response intercept(Chain chain) throws IOException {
        Request newRequest  = chain.request().newBuilder()
            .addHeader("Authorization", "Bearer " + token)
            .build();
        return chain.proceed(newRequest);
      }
    }).build();

Retrofit retrofit = new Retrofit.Builder()
    .client(client)
    .baseUrl(/** your url **/)
    .addConverterFactory(GsonConverterFactory.create())
    .build();
