2621 :: Httpclient Extra Headers Error

• alfrednewman (orginal) [2016-11-14T17:51:22+01:00] view original

  Greetings,

  I'm trying to consume an JSON API, but I need to pass some Headers along my GET call.

  My code is the following:

  import httpclient, json
  
  let client = newHttpClient()
  client.headers = newHttpHeaders({ "Content-Type": "application/json" })
  
  let body = %*{
      "data": "some text"
  }
  
  var xheaders = ""
  xheaders = xheaders & "x-mashape-proxy-secret:" & "asdfgqwert" & "\c\L"
  xheaders = xheaders & "x-mashape-User:" & "poiuylkjhg" & "\c\L"
  
  client.request("http://127.0.0.1:5000/region?country=xx&area-code=17", httpMethod = HttpGet, extraHeaders = xheaders, body = $body)
  Run

  However, I'm getting the error: myhttpclient.nim(20, 12) Error: type mismatch: got (HttpClient, string, httpMethod: HttpMethod, extraHeaders: string, body: string)

  Something is wrong over here, but I'm stucked...

  Thanks for any help.

  Cheers

  You're mixing old and new API here. request proc from old API (the one that doesn't use HttpClient) does indeed have extraHeaders parameter. It is, however, deprecated. The new API tends to pass headers in a client. There is, however, an option to pass per-request headers to new request proc in current devel branch: https://github.com/nim-lang/Nim/blob/52f20abf22b589bafdf93da024753f71b0e2495b/lib/pure/httpclient.nim#L1003-L1005

  @pdv, thank you for your support. Can you pls kindly help me to fix my code ? I tried to rewrite it following the description of the provided branch, but I got no success. I think I'm missing some key concept. All the best, AN

  Here is a working example:

  import httpclient, json
  
  let client = newHttpClient()
  client.headers = newHttpHeaders({ "Content-Type": "application/json",
                                    "x-mashape-proxy-secret": "asdfgqwert",
                                    "x-mashape-User": "asd"})
  
  let body = %*{
      "data": "some text"
  }
  
  var resp = client.request("http://127.0.0.1:5000/region?country=xx&area-code=17", httpMethod = HttpGet, body = $body)
  Run
