I have a web API and I am calling another API inside of a controller as follows. I wonder if I can convert json string content to form post data type while sending to this API.
// POST: api/Game
//[RequireHttps] For Prod Only
[HttpPost, Route("initiation")]
public async Task<IHttpActionResult> PostInitiate(InitiateRequest initiate)
{
if (!ModelState.IsValid)
{
return BadRequest(ModelState);
}
#region Call Game
var httpClient = new HttpClient();
HttpContent content = new StringContent(
JsonConvert.SerializeObject(initiate),
Encoding.UTF8,
"application/x-www-form-urlencoded"
);
var response =
await httpClient.PostAsync("https://test.com/purchaseinitiation",content);
switch (response.StatusCode)
{
case HttpStatusCode.NotFound:
{
return NotFound();
}
case HttpStatusCode.InternalServerError:
{
return InternalServerError();
}
case HttpStatusCode.OK:
{
//Adding Response into database
context.InitiateResponses.Add(initiateResponse);
await context.SaveChangesAsync();
return Ok(initiateResponse);
}
case HttpStatusCode.BadRequest:
{
return BadRequest(htmlResponse);
}
case HttpStatusCode.Unauthorized:
{
return Unauthorized();
}
case HttpStatusCode.RequestTimeout:
{
return InternalServerError();
}
default:
{
htmlResponse = await response.Content.ReadAsStringAsync();
break;
}
}
return Ok(htmlResponse);
}
Your question and code is confusing. For starters, the code does not compile. Content is not defined. Is there any reason why you can't simply deserialize the JSON into a an object the use basic string concatenation to build the POST data?
StringContent content = new StringContent(JsonConvert.SerializeObject(yourObject), Encoding.UTF8, "application/json");
var response = await httpClient.PostAsync("https://test.com/purchaseinitiation", content));

serialize json string to a form post data

Hi guys,
I have a web API and I am calling another API inside of a controller as follows. I wonder if I can convert json string content to form post data type while sending to this API.
// POST: api/Game //[RequireHttps] For Prod Only [HttpPost, Route("initiation")] public async Task<IHttpActionResult> PostInitiate(InitiateRequest initiate) { if (!ModelState.IsValid) { return BadRequest(ModelState); } #region Call Game var httpClient = new HttpClient(); HttpContent content = new StringContent( JsonConvert.SerializeObject(initiate), Encoding.UTF8, "application/x-www-form-urlencoded" ); var response = await httpClient.PostAsync("https://test.com/purchaseinitiation",content); switch (response.StatusCode) { case HttpStatusCode.NotFound: { return NotFound(); } case HttpStatusCode.InternalServerError: { return InternalServerError(); } case HttpStatusCode.OK: { //Adding Response into database context.InitiateResponses.Add(initiateResponse); await context.SaveChangesAsync(); return Ok(initiateResponse); } case HttpStatusCode.BadRequest: { return BadRequest(htmlResponse); } case HttpStatusCode.Unauthorized: { return Unauthorized(); } case HttpStatusCode.RequestTimeout: { return InternalServerError(); } default: { htmlResponse = await response.Content.ReadAsStringAsync(); break; } } return Ok(htmlResponse); }My sample http content:
{"ApplicationCode"="52e7cf966b724749a7c4efadc3727ed7","productCode":"000000006479","quantity":1,"version":"V1","signature":"7a98eaa454750b9b591ee7a65f13accb","customerID":1}How I would like to send:

If I deserialize it into an object how can I post as follows?
var response = await httpClient.PostAsync("https://test.com/purchaseinitiation",content);Participant

You have to do something like this:

Instead of JSON you would like to send the data as:
You can do it the same way:

I would prefer StringBuilder class here.
