改造网络调用在工作应用程序中突然出现协议异常而失败。该应用程序一直工作到昨天，今天所有的网络调用都失败了。这些调用在 HTTP 上运行良好，但在 HTTPS 上失败。

这是日志，

java.net.ProtocolException: Expected ':status' header not present

经过几个小时的混乱，终于找到了解决方案。将 Retrofit 和 Okhttp3 库更新到最新版本对我有用。

compile 'com.squareup.okhttp3:okhttp:3.9.0'

compile 'com.squareup.retrofit2:retrofit:2.3.0'

我正在使用OkHttp2（2.7.5），我通过强制客户端使用HTTP 1.1协议解决了这个问题

OkHttpClient client = new OkHttpClient();
client.setProtocols(Arrays.asList(Protocol.HTTP_1_1)); // <- add this line

今天遇到了同样的问题。原因是将服务器上的 nginx 更新到最新版本（1.13.6）。如果他们没有更新服务器上的 nginx，请询问您的后端团队。

我用的是okhttp3（okhttp-3.4.1），okhttp3对HTTP_1.1协议不是很兼容，需要手动添加。可以看官方链接

OkHttpClient.Builder builder = new OkHttpClient.Builder();
//protocols
List<Protocol> protocols = new ArrayList<Protocol>();
protocols.add(Protocol.HTTP_1_1);
protocols.add(Protocol.HTTP_2);
builder.protocols(protocols);
