流被重置：PROTOCOL_ERROR，同时在 3G 网络中使用 Retrofit

Question

大家中午好！

我Retrofit在我的应用程序中用于网络调用。该应用程序运行良好，速度非常快。感谢精彩的图书馆。但是，它仅适用于 wi-fi。如果我在 3G 网络中运行该应用程序，则会引发错误。stream was reset: PROTOCOL_ERROR, while using Retrofit in 3G network

我已将此 jar 文件导入到构建路径：

这是完整的堆栈跟踪：

谷歌没有帮助我。如果你能帮我解决这个问题，那就太好了。谢谢。

Answer 1

我通过限制请求使用 HTTP 1 解决了类似的问题，请参阅：

OkHttpClient okHttpClient = new OkHttpClient();
okHttpClient.setProtocols(Arrays.asList(Protocol.HTTP_1_1));

Answer 2

看起来像是 OkHtttp 或您的网络服务器的 SPDY 或 HTTP/2 实现中的错误。升级到 OkHttp/2.1。如果这不能解决问题，请在 OkHttp 的问题跟踪器上打开一个问题，并包含导致您悲伤的服务器的主机名。
