[SOLVED] Turn Golang http.Request struct to cURL command

Issue

In my debugging process of a microservice, I want to know how my client service request finally looks like, to make sure is the problem from client service or the target service.

For this purpose, I need a tool (or pkg) to turn http.Request struct to a cURL command

example of http.Request struct:

{
    Method:POST
    URL:https://some-fake-url.com
    Proto:HTTP/1.1
    ProtoMajor:1
    ProtoMinor:1
    Accept-Encoding:[gzip, deflate, br]
    Accept-Language:[en-US,en;q=0.9]
    Authorization:[Bearer gkasgjagsljkg]
    Connection:[keep-alive]
    Content-Length:[0]
    Content-Type:[application/json]
    ...
}

The client service use this request with http.DefaultClient.Do(),

I don't want to manually turn this into a cURL because that may not be valid.

Solution

You can turn your Golang requests to cURL command with http2curl pkg like below:

import (
    "http"
    "moul.io/http2curl"
)

data := bytes.NewBufferString(`{"hello":"world","answer":42}`)
req, _ := http.NewRequest("PUT", "http://www.example.com/abc/def.ghi?jlk=mno&pqr=stu", data)
req.Header.Set("Content-Type", "application/json")

command, _ := http2curl.GetCurlCommand(req)
fmt.Println(command)
// Output: curl -X PUT -d "{\"hello\":\"world\",\"answer\":42}" -H "Content-Type: application/json" http://www.example.com/abc/def.ghi?jlk=mno&pqr=stu
