TL;DR -- How do I send a JSON string to a REST host with an auth header? I've tried 3 different approaches found one that works with anonymous types. Why can't I use anonymous types? I need to set a variable called "Group-Name", and a hyphen isn't a valid C# identifier.
Background
I need to POST JSON but am unable to get the body and the content type correct
Function #1 - Works with anonymous types
The content type and data is correct, but I don't want to use anonymous types. I want to use a string
static void PostData(string restURLBase, string RESTUrl, string AuthToken, string postBody)
{
HttpClient client = new HttpClient();
client.BaseAddress = new Uri(restURLBase);
client.DefaultRequestHeaders.Add("Auth-Token", AuthToken);
client.DefaultRequestHeaders.Accept.Add(new MediaTypeWithQualityHeaderValue("application/json"));
// StringContent content = new StringContent(postBody);
var test1 = "data1";
var test2 = "data2";
var test3 = "data3";
var response = client.PostAsJsonAsync(RESTUrl, new { test1, test2, test3}).Result; // Blocking call!
if (!response.IsSuccessStatusCode)
{
Console.WriteLine("{0} ({1})", (int)response.StatusCode, response.ReasonPhrase);
return;
}
}
Output #1
Content type and data is correct when using AnonymousTypes + PostAsJsonAsync, but I don't want to use anonymous types.
POST https://api.dynect.net/REST/Zone/ABCqqqqqqqqqqqqYYYYYtes3ss.com HTTP/1.1
Auth-Token: --- REDACTED -----
Accept: application/json
Content-Type: application/json; charset=utf-8
Host: api.dynect.net
Content-Length: 49
Expect: 100-continue
{"test1":"data1","test2":"data2","test3":"data3"}
Function #2 - Doesn't work as expected
Take a string and put it into a StringContent object. This has a side effect of changing the content type.
static void PostData(string restURLBase, string RESTUrl, string AuthToken, string postBody)
{
HttpClient client = new HttpClient();
client.BaseAddress = new Uri(restURLBase);
client.DefaultRequestHeaders.Add("Auth-Token", AuthToken);
client.DefaultRequestHeaders.Accept.Add(new MediaTypeWithQualityHeaderValue("application/json"));
StringContent content = new StringContent(postBody);
var response = client.PostAsync(RESTUrl, content).Result; // Blocking call!
if (!response.IsSuccessStatusCode)
{
Console.WriteLine("{0} ({1})", (int)response.StatusCode, response.ReasonPhrase);
return;
}
}
Output #2
Content type is wrong when using StringContent + PostAsync
POST https://api.dynect.net/REST/Zone/ABCqqqqqqqqqqqqYYYYYtes3ss.com HTTP/1.1
Auth-Token: ---- REDACTED -------
Accept: application/json // CORRECT
Content-Type: text/plain; charset=utf-8 // WRONG!!!
Host: api.dynect.net
Content-Length: 100
Expect: 100-continue
{"rdata" : ["rname" : "dynect.nfp.com", "zone" : "ABCqqqqqqqqqqqqYYYYYtes3ss.com"], "ttl" : "43200"}
// ^^ THIS IS CORRECT
Function #3 - Doesn't work as expected
Since I know PostAsJsonAsync
sets the contentType correctly, lets use that method. (doesn't work)
static void PostData(string restURLBase, string RESTUrl, string AuthToken, string postBody)
{
HttpClient client = new HttpClient();
client.BaseAddress = new Uri(restURLBase);
client.DefaultRequestHeaders.Add("Auth-Token", AuthToken);
client.DefaultRequestHeaders.Accept.Add(new MediaTypeWithQualityHeaderValue("application/json"));
StringContent content = new StringContent(postBody);
var response = client.PostAsJsonAsync(RESTUrl, content).Result; // Blocking call!
if (!response.IsSuccessStatusCode)
{
Console.WriteLine("{0} ({1})", (int)response.StatusCode, response.ReasonPhrase);
return;
}
}
Output #3
Content type is correct, POST body is wrong when using StringContent + PostAsJsonAsync
POST https://api.dynect.net/REST/Zone/ABCqqqqqqqqqqqqYYYYYtes3ss.com HTTP/1.1
Auth-Token: -- REDACTED ---
Accept: application/json
Content-Type: application/json; charset=utf-8
Host: api.dynect.net
Content-Length: 74
Expect: 100-continue
{"Headers":[{"Key":"Content-Type","Value":["text/plain; charset=utf-8"]}]}
Question
All I want to do is send JSON as a string, or dynamic object defined at runtime, to a server, with HTTP content type correct, and with a special 'Auth-Token' header.
Any example, if not using WebAPI, such as servicestack, or anything else is cool.
It's constructor of StringContent. Looks like that you should specify appropriate Encoding and mediaType
