OkHttp Android流已重置:HTTP_1_1_REQUIRED

Question

我们正在开发一个Android应用程序，该应用程序应该使用HTTP/2连接到我们的Azure应用程序服务。在Azure App服务上，我们通过使用以下博客文章中的步骤启用了HTTP/2:https://blogs.msdn.microsoft.com/appServiceeam/2018/04/13/uncasting-http2-support-in-azure-app-service/

我们使用的是OKHTTP3.10.0版。

在生成器中添加此行

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

像这样

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