Python 成功部署到云运行后无法命中grpc服务器

类似的情况，但是，在我的案例中描述的解决方案不起作用。我想在google cloud run上运行grpc服务器，并能够调用它。我有一个基本的python grpc服务器，工作正常，在本地主机上使用

docker run

运行

gcr.io

映像时，我的客户端可以调用它。但是，在成功部署到google cloud run之后，服务器在端口8080上侦听（我记录了它），我无法再使用客户端代码访问服务器

我收到以下消息：

grpc._channel._InactiveRpcError: <_InactiveRpcError of RPC that terminated with:
    status = StatusCode.UNAVAILABLE
    details = "DNS resolution failed"
    debug_error_string = "{"created":"@1591245267.073965000","description":"Failed to pick subchannel","file":"src/core/ext/filters/client_channel/client_channel.cc","file_line":3981,"referenced_errors":[{"created":"@1591245267.073946000","description":"Resolver transient failure","file":"src/core/ext/filters/client_channel/resolving_lb_policy.cc","file_line":214,"referenced_errors":[{"created":"@1591245267.073945000","description":"DNS resolution failed","file":"src/core/ext/filters/client_channel/resolver/dns/c_ares/dns_resolver_ares.cc","file_line":357,"grpc_status":14,"referenced_errors":[{"created":"@1591245267.073882000","description":"C-ares status is not ARES_SUCCESS: Domain name not found","file":"src/core/ext/filters/client_channel/resolver/dns/c_ares/grpc_ares_wrapper.cc","file_line":244,"referenced_errors":[{"created":"@1591245267.059636000","description":"C-ares status is not ARES_SUCCESS: Domain name not found","file":"src/core/ext/filters/client_channel/resolver/dns/c_ares/grpc_ares_wrapper.cc","file_line":244}]}]}]}]}"

我的客户端代码，我两个都试过了

channel = grpc.insecure_channel('<the .run.app url on my cloud run service>:8080')
stub = my_service_pb2_grpc.MyServiceStub(channel)
request = my_service_pb2.MyEndpointRequest(
    test='hello'
)
response = stub.MyEndpoint(request)
print(response)

channel=grpc.unsecure_channel（':8080'）
存根=my_service_pb2_grpc.MyServiceStub（频道）
request=my\u service\u pb2.MyEndpointRequest(
测试class='hello'
)
response=stub.MyEndpoint（请求）
打印（答复）

及

使用grpc.secure_通道（':8080'，grpc.ssl_通道_凭据（））作为通道：
存根=my_service_pb2_grpc.MyServiceStub（频道）
request=my\u service\u pb2.MyEndpointRequest(
测试class='hello'
)
response=stub.MyEndpoint（请求）
打印（答复）

这两个都不起作用，给我的错误与我上面写的相同

此外，当我在命令行上执行

ping

时，我会得到

名称或服务未知

任何帮助都将不胜感激

设法解决了这个问题，解决方案是从云运行服务上显示的url中删除

https://

前缀，并使用

443

端口而不是

8080

with grpc.secure_channel(
        '<url without https:// prefix>:443',
        grpc.ssl_channel_credentials(),
) as channel:
    stub = my_service_pb2_grpc.MyServiceStub(channel)
    request = my_service_pb2.MyEndpointRequest(
        test='hello'
    )
    response = stub.MyEndpoint(request)
    print(response)

与grpc.secure\u通道(
':443',
grpc.ssl\u通道\u凭据（），
)作为频道：
存根=my_service_pb2_grpc.MyServiceStub（频道）
request=my\u service\u pb2.MyEndpointRequest(
测试class='hello'
)
response=stub.MyEndpoint（请求）
打印（答复）
