How to curl a POST endpoint with a protobuf payload
问题
我有一个Java服务中的POST端点，它期望一个Protobuf 3负载。其他服务使用这个服务发送Protobuf负载。我想要做一些调试，并通过curl命令发送一个Protobuf负载到该服务，然而，我不知道如何构造这样的负载，因为它是一个二进制协议。
英文:
I have a POST endpoint in my Java service that expects a protobuf 3 payload. This service is used by other services which send the protobuf payload. I would like to do some debugging and send a protobuf payload to the service via a curl command, however, I have no idea how to construct such a payload, given it's a binary protocol.

你可以使用 protoCURL 来实现这个目的。它是一个命令行工具，用于发送和接收 Protobuf HTTP REST 请求，同时将它们编写成 Protobuf Text 或 JSON 格式。
一个请求可能看起来像这样：
protocurl -I path/to/protos -i ..MyRequest -o ..MyResponse \
-u http://host/path/o/endpoint -d 'someField: "some-string", someIntField: 42'
响应可能如下所示：
=========================== Request Text =========================== >>>
someField: "my-string"
someIntField: 42
=========================== Response Text =========================== <<<
someResponseField: "The answer for everything!"
someOtherResonseMessage: {
fooEnum: BAR
}
你可以在 repository 中找到更多使用示例。

And the response may look like this:
=========================== Request Text =========================== >>>
someField: "my-string"
someIntField: 42
=========================== Response Text =========================== <<<
someResponseField: "The answer for everything!"
someOtherResonseMessage: {
fooEnum: BAR
}
You can find more examples for how to use it in the repository.
