我试图通过使用拦截器在Android中的Retrofit 2.0-beta3和OkHttpClient添加基于令牌的身份验证.但是当我在OkHttpClient中添加拦截器时,我得到UnsupportedOperationException.这是我的代码:在ApiClient.java中

public static TrequantApiInterface getClient(final String token) {
        if( sTreqantApiInterface == null) {

            Log.v(RETROFIT_LOG, "Creating api client for the first time");
            OkHttpClient okClient = new OkHttpClient();

            okClient.interceptors().add(new Interceptor() {
                @Override
                public Response intercept(Interceptor.Chain chain) throws IOException {
                    Request original = chain.request();

                    // Request customization: add request headers
                    Request.Builder requestBuilder = original.newBuilder()
                            .header("Authorization", token)
                            .method(original.method(), original.body());

                    Request request = requestBuilder.build();
                    return chain.proceed(request);
                }
            });

            Retrofit client = new Retrofit.Builder()
                    .baseUrl(baseUrl)
                    .client(okClient)
                    .addConverterFactory(GsonConverterFactory.create())
                    .build();
            sTreqantApiInterface = client.create(TrequantApiInterface.class);
        }
        return sTreqantApiInterface;
    } …

我正在运行 Django、uwsgi、ngix 服务器。我的服务器适用于较小尺寸的 GET、POST 请求。但是在POST大尺寸的请求时，nginx返回502：nginx error.log是：

2016/03/01 13:52:19 [error] 29837#0: *1482 sendfile() failed (32: Broken pipe) while sending request to upstream, client: 175.110.112.36, server: server-ip, request: "POST /me/amptemp/ HTTP/1.1", upstream: "uwsgi://unix:///tmp/uwsgi.sock:", host: "servername"

因此，为了找到真正的问题所在，我在不同的端口上运行 uwsgi 并检查同一请求是否发生任何错误。但是请求成功了。因此，问题出在 nginx 或 unix 套接字配置上。Ngin-x 配置：

# the upstream component nginx needs to connect to
upstream django {
     server unix:///tmp/uwsgi.sock; # for a file socket
#   server 127.0.0.1:8001; # for a web port socket (we'll use this first)
}

# configuration of the server
