Retrofit2.0 添加Header的方法总结

一、使用注解
1. 添加单个header

public interface ApiService {
    @Headers("Content-Type: application/javascript")
    @GET("/data")
    Call<List<AddressBean>> getData();
}

2. 添加多个header

public interface ApiService {
    @Headers({
            "Content-Type: application/javascript",
            "User-Agent: YourAgent"
    })
    @GET("/data/{user_id}")
    Call<List<AddressBean>> getData();
}

3. 动态添加header

public interface ApiService {
    @GET("/data")
    Call<List<AddressBean>> getData(@Header("Content-Range") String contentRange);
}

4. 动态添加多个header

@GET("/search")
Call<ResponseBody> list(@HeaderMap Map<String, String> headers);

1. Post添加单个header

@POST("api/sys/getPermissions")
Observable<ResponseBean<PermissionsBean>> getPermissions(@Query("__token") String token);

2.post添加固定的多个header
 

@POST("api/sys/getPermissions")
 @Headers({"Content-Type:application/x-www-form-urlencoded",
            "Authorization:Basic VmJyZjJNU1FxejhBVlhzMmajhETkJV"})
 Observable<TokenBean> getSsoToken();

二、如果要添加全局header，则需要在代码中添加header
 

   /**
     * 请求拦截器
     */
    private class RequestInterceptor implements Interceptor {
        @Override
        public okhttp3.Response intercept(Chain chain) throws IOException {
 
            Request oldRequest = chain.request();
            Request request = oldRequest.newBuilder()
                    .headers(Headers.of(getHeaders()))//注入头信息
                    .build();
            logRequest(request);
            return logResponse(chain.proceed(request));
        }
    }
 
    /**
     * 获取头信息
     */
    private Map<String, String> getHeaders() {
        HashMap<String, String> headersMap = new HashMap<>();
        headersMap.put("Cookie","jeeplus.session.id");
        return headersMap;
    }
