在这段代码中,通过引入与methodConfig同级的retryThrottling配置,之后gRPC客户端会维护一个tokenCount的变量,它的初始值为maxToken,值得范围在0-maxToken波动,之后每一次请求成功时,tokenCount都会递增tokenRatio的值,每次请求失败时,tokenCount都会递减1,之后在重试之前如果发现tokaneCount小于或等于maxToken/2时,gRPC客户...
gRPC的channel在初始化的时候可以指定options参数,我们之前指定了最大发送和最大接收的字节数大小,这里也可以指定自动重试的配置,详情参考:https://github.com/grpc/proposal/blob/master/A6-client-retries.md,默认情况下gRPC会执行透明重试,透明重试会在服务端的应用逻辑并没有接收到请求的时候,gRPC 会进行自动的重试。

"grpc_message":"Established channel does not have a sufficient security level to transfer call credential.","grpc_status":16}" 本例连接异常是因为grpcio版本太高,grpcio==1.45.0 降级后解决 pip uninstall grpcio pip install grpcio==1.19.0
使用gRPC提供的grpc.Status.UNAVAILABLE状态码来判断客户端连接是否断开。 使用线程定时发送心跳包来检测客户端连接状态。 当客户端连接断开时,通过回调函数来处理断开连接事件。 代码示例 importgrpcdefdetect_connection_status(stub):try:response=stub.Ping(grpc.Empty())exceptgrpc.RpcErrorase:ife.code()==grpc.Sta...
1. 在.proto文件使用enum时,遇到0无法字符串序列化的问题,表现为: 返回VALID可以,INVALID没有返回值。修改如下: 2. exception context.set_code(grpc.StatusCode.INVALID_ARGUMENT)context.set_details('wrong token')returnauthsvc_pb2.validResponse()
