8024 :: httpclient request with host different from url

• IzidoroBaltazar (orginal) [2021-05-24T13:40:10+02:00] view original

  How can I route http request through different host?

  With python requests I can do following:

  Run

  In nim when I try to do similar.

  client.headers = newHttpHeaders({"Content-Type": "application/json", "Host": "other-url.com"})
  let response = client.request(url, httpMethod = HttpPost, body = $body)
  Run

  I'm getting error on the server.

  
  Found multiple Host: headers
  Run

  How can I override host when using httpclient library?

  Hmmm, I get only one Host header locally with netcat:

  
  POST / HTTP/1.1
  Connection: Keep-Alive
  content-length: 20
  content-type: application/json
  host: other-url.com
  user-agent: Nim httpclient/1.4.4
  
  {"data":"some text"}
  Run

  Code:

  import httpclient, json
  
  let client = newHttpClient()
  client.headers = newHttpHeaders({"Content-Type": "application/json",
      "Host": "other-url.com"})
  let body = %*{
      "data": "some text"
  }
  let response = client.request("http://localhost:1234", httpMethod = HttpPost, body = $body)
  echo response.status
  Run

  Maybe something is wrong with header casing? Try with titleCase = true:

  client.headers = newHttpHeaders({"Content-Type": "application/json", "Host": "other-url.com"},  titleCase = true)
  Run

  Thank you for the answer. It seems this problem was related to the old nim version 1.0.6 official for Ubuntu 20.04. I upgraded through snap to 1.4.6 and request works.
