将Postman与GRPC一起使用

发布于 2025-02-09 06:28:34 字数 1320 浏览 2 评论 0原文

我有以下“ Hello World” GRPC Serivice在AC＃中工作，vs 2022 Console Client致电HTTP和HTTPS端点；但是，当使用邮递员用于Windows（VER 9.21.3）时，我会遇到错误。

原始：

service Greeter {
  // Sends a greeting
  rpc SayHello (HelloRequest) returns (HelloReply);
}

// The request message containing the user's name.
message HelloRequest {
  string name = 1;
}

// The response message containing the greetings.
message HelloReply {
  string message = 1;
}

post http：// localhost：5046/enterer/sayhello

＆gt; RAW＆GT; {“名称”：“测试GRPC HTTP”}

Postman响应 - ＆GT; “解析错误：服务器返回了错误的响应”

Postman控制台 - ＆GT; “错误：解析错误：预期HTTP/” C＃GRPC服务器控制台 - ＆GT;无

帖子https：// localhost：7046/enterer/sayhello

＆gt; RAW＆GT; {“名称”：“测试GRPC HTTPS”} Postman响应 - ＆GT; “错误：套接字挂起”

C＃GRPC服务器控制台 - ＆GT; “ TLS上的HTTP/2没有在HTTP/2仅端点上协商。”

有人在C＃/VS2022/Postman堆栈中取得成功吗？

更新

我现在通过@laurentgabiot发布的链接创建我的请求： https://blog.postman.com/postman-now-now-now-now-supports-grpc/ < /a>

现在，我的两个http/https端点都会遇到相同的错误：

“错误：无效协议：https”

在其示例中，他们的端点是：“ Grpcb.in：9000”这意味着。不确定如何在VS2022/C＃中执行此操作。

注意：我要留下我的原始错误（上图），以防其他人以与我相同的方式创建他们的请求。

原文

I've got the following "hello world" gRPC serivice working in a c#, VS 2022 console client calling both http and https endpoints; but I get errors when using Postman for Windows (ver 9.21.3) calling the same endpoints.

proto:

service Greeter {
  // Sends a greeting
  rpc SayHello (HelloRequest) returns (HelloReply);
}

// The request message containing the user's name.
message HelloRequest {
  string name = 1;
}

// The response message containing the greetings.
message HelloReply {
  string message = 1;
}

post http://localhost:5046/Greeter/SayHello

body > raw > {"Name" : "testing grpc http"}

postman response -> "Parse Error: The server returned a malformed response"

postman console -> "Error: Parse Error: Expected HTTP/" c# grpc server console -> none

post https://localhost:7046/Greeter/SayHello

body > raw > {"Name" : "testing grpc HTTPS"} postman response -> "Error: socket hang up"

c# grpc server console -> "HTTP/2 over TLS was not negotiated on an HTTP/2-only endpoint."

Anyone having success with the c#/VS2022/Postman stack?

UPDATE

I'm now creating my request via the link posted by @LaurentGabiot here:
https://blog.postman.com/postman-now-supports-grpc/

and am now getting the same error for both of my http/https endpoints:

"Error: Invalid protocol: https"
