OkHttp Android流已重置：需要HTTP_1_1_

我们正在开发一个Android应用程序，它应该使用Http/2连接到我们的Azure应用程序服务。 在Azure应用程序服务上，我们使用以下博文中的步骤启用了Http/2：

我们的请求由相互SSL保护，因此应用程序必须发送其客户端证书

当我们尝试使用OkHttp执行对我们的应用程序服务的调用时，我们总是会得到以下错误和堆栈跟踪。当我们尝试使用相同的Android代码调用twitter api时，这是可行的

有人知道如何解决这个问题吗

我们使用的是OkHttp版本3.10.0

HTTP/2目前并不真正支持客户端证书，尤其是当此类连接仅应用于服务器上的某些资源时。有，但还没有标准化，而且，至少还没有任何实施支持

在支持此操作之前，请使用HTTP_1_1_所需的错误代码，客户端应使用HTTP/1.1重试

与Azure一样，也要这样做。

在builder中添加此行

.protocols(Util.immutableList(Protocol.HTTP_1_1))

像这样

 private OkHttpClient client = new OkHttpClient.Builder()
            .protocols(Util.immutableList(Protocol.HTTP_1_1))
            .build();

这很奇怪。因为当我使用边缘浏览器通过客户端证书连接到Azure端点时。它正确地返回了一个响应，我看到HTTP/2与网络监视器一起使用。。。这意味着它支持客户端证书。额外信息：客户端证书确实适用于服务器上的每个资源。不仅限于特定的端点。
