http2curl

📐 Convert Golang's http.Request to CURL command line

To do the reverse operation, check out mholt/curl-to-go.

Example

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

func GetCurlCommand

func GetCurlCommand(req *http.Request) (*CurlCommand, error)

GetCurlCommand returns a CurlCommand corresponding to an http.Request

Example

form := url.Values{}
form.Add("age", "10")
form.Add("name", "Hudson")
body := form.Encode()

req, _ := http.NewRequest(http.MethodPost, "http://foo.com/cats", ioutil.NopCloser(bytes.NewBufferString(body)))
req.Header.Set("API_KEY", "123")

command, _ := GetCurlCommand(req)
fmt.Println(command)

Output:
curl -X 'POST' -d 'age=10&name=Hudson' -H 'Api_key: 123' 'http://foo.com/cats'

Example (EmptyStringBody)

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

command, _ := GetCurlCommand(req)
fmt.Println(command)

Output:
curl -X 'PUT' -H 'Content-Type: application/json' 'http://www.example.com/abc/def.ghi?jlk=mno&pqr=stu'

Example (Https)

uri := "https://www.example.com/abc/def.ghi?jlk=mno&pqr=stu"
payload := new(bytes.Buffer)
payload.Write([]byte(`{"hello":"world","answer":42}`))
req, err := http.NewRequest("PUT", uri, payload)
if err != nil {
	panic(err)
}
req.Header.Set("X-Auth-Token", "private-token")
req.Header.Set("Content-Type", "application/json")

command, err := GetCurlCommand(req)
if err != nil {
	panic(err)
}
fmt.Println(command)

Output:
curl -k -X 'PUT' -d '{"hello":"world","answer":42}' -H 'Content-Type: application/json' -H 'X-Auth-Token: private-token' 'https://www.example.com/abc/def.ghi?jlk=mno&pqr=stu'

Example (Json)

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

command, _ := 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'

Example (NewlineInBody)

req, _ := http.NewRequest("POST", "http://www.example.com/abc/def.ghi?jlk=mno&pqr=stu", bytes.NewBufferString("hello\nworld"))
req.Header.Set("Content-Type", "application/json")

command, _ := GetCurlCommand(req)
fmt.Println(command)

Output:
curl -X 'POST' -d 'hello
world' -H 'Content-Type: application/json' 'http://www.example.com/abc/def.ghi?jlk=mno&pqr=stu'

Example (NoBody)

req, _ := http.NewRequest("PUT", "http://www.example.com/abc/def.ghi?jlk=mno&pqr=stu", nil)
req.Header.Set("Content-Type", "application/json")

command, _ := GetCurlCommand(req)
fmt.Println(command)

Output:
curl -X 'PUT' -H 'Content-Type: application/json' 'http://www.example.com/abc/def.ghi?jlk=mno&pqr=stu'

Example (Other)

uri := "http://www.example.com/abc/def.ghi?jlk=mno&pqr=stu"
payload := new(bytes.Buffer)
payload.Write([]byte(`{"hello":"world","answer":42}`))
req, err := http.NewRequest("PUT", uri, payload)
if err != nil {
	panic(err)
}
req.Header.Set("X-Auth-Token", "private-token")
req.Header.Set("Content-Type", "application/json")

command, err := GetCurlCommand(req)
if err != nil {
	panic(err)
}
fmt.Println(command)

Output:
curl -X 'PUT' -d '{"hello":"world","answer":42}' -H 'Content-Type: application/json' -H 'X-Auth-Token: private-token' 'http://www.example.com/abc/def.ghi?jlk=mno&pqr=stu'

Example (Slice)

// See https://github.com/moul/http2curl/issues/12
req, _ := http.NewRequest("PUT", "http://www.example.com/abc/def.ghi?jlk=mno&pqr=stu", bytes.NewBufferString(`{"hello":"world","answer":42}`))
req.Header.Set("Content-Type", "application/json")

command, _ := GetCurlCommand(req)
fmt.Println(strings.Join(*command, " \\\n  "))

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'

Example (SpecialCharsInBody)

req, _ := http.NewRequest("POST", "http://www.example.com/abc/def.ghi?jlk=mno&pqr=stu", bytes.NewBufferString(`Hello $123 o'neill -"-`))
req.Header.Set("Content-Type", "application/json")

command, _ := GetCurlCommand(req)
fmt.Println(command)

Output:
curl -X 'POST' -d 'Hello $123 o'\''neill -"-' -H 'Content-Type: application/json' 'http://www.example.com/abc/def.ghi?jlk=mno&pqr=stu'
