android - 如何在我的请求 header 中添加授权？

Question

我需要在我的请求中添加授权 header ，它必须如下所示:

"Authorization: Basic Zm9vOmJhcg=="

我有用户名和密码的值，如何将其添加到 Retrofit 2 的请求中？这看起来很简单，但我不知道我可以在我的 Fragment 中的什么地方初始化这个 header ？

我的 fragment 类:

public class FeedFragment extends Fragment {
    EditText username;
    EditText password;
    Button btnLogin;

    public List<SignInResult> signInResult;
    String username_value,password_value;
    public static final String ROOT_URL = "https://api.vid.me/";

    public View onCreateView(LayoutInflater inflater, ViewGroup container,
                             Bundle savedInstanceState) {
        View rootView = inflater.inflate(R.layout.fragment_feed, container, false);
        username = (EditText) rootView.findViewById(R.id.user_name_field);
        password = (EditText) rootView.findViewById(R.id.password_field);
        btnLogin = (Button) rootView.findViewById(R.id.button_login);
        btnLogin.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                Authorize();
            }
        });
        return rootView;
    }

    public void Authorize() {
        Retrofit retrofitAdapter = new Retrofit.Builder()
                .addConverterFactory(GsonConverterFactory.create())
                .baseUrl(ROOT_URL)
                .build();
        final VideoApi videoApi = retrofitAdapter.create(VideoApi.class);

         username_value = username.getText().toString();
         password_value = password.getText().toString();

        Call<SignInResults> call = videoApi.insertUser(username_value,password_value);
        call.enqueue(new Callback<SignInResults>() {


            @Override
            public void onResponse(Call<SignInResults> call, Response<SignInResults> response) {
                SignInResults results = response.body();
                Log.d("Response ==>> ", new GsonBuilder().setPrettyPrinting().create().toJson(results));

            }

            @Override
            public void onFailure(Call<SignInResults> call, Throwable t) {

            }
        });
    }
}

我的 API 接口(interface):

public interface VideoApi {

    @GET("/videos/featured")
    Call<Videos> getFeaturedVideo();

    @GET("/videos/new")
    Call<Videos> getNewVideo();

@Headers("Content-Type:application/x-www-form-urlencoded")
    @FormUrlEncoded
    @POST("/auth/create")
   Call<SignInResults>insertUser(@Field("email") String username,
      @Field("password") String password
   );
}

根据用例，您可以采用两种方法。

第一种方式:使用okhttp客户端为你的请求添加拦截器

final String myToken = "Zm9vOmJhcg==";
Interceptor interceptor = new Interceptor() {
  @Override
  public okhttp3.Response intercept(Chain chain) throws IOException {
    Request newRequest = chain.request().newBuilder()
       .addHeader("Authorization", "Basic " + yourtoken).build();
    return chain.proceed(newRequest);
  }
};

OkHttpClient.Builder builder = new OkHttpClient.Builder();
builder.interceptors().add(interceptor);
OkHttpClient client = builder.build();

现在更改您的 retrofit 电话。

Retrofit retrofitAdapter = new Retrofit.Builder()
     .addConverterFactory(GsonConverterFactory.create())
     .baseUrl(ROOT_URL)
     .client(client)
     .build();

第二种方式:将 header 添加到您的 API 调用

Call<SignInResults>insertUser(
      @Header("Authorization") String token,
      @Field("email") String username,
      @Field("password") String password
   );
