How do I convert the string returned for "PayloadResponse" to a HTTPResponse? I've tried the following but am not able to retrieve the body of the response:
var response = JObject.Parse(await httpResponseMessage.Content.ReadAsStringAsync());
var payloadResponse = response["ProcessCardSwipeOutputs"][0]["PayloadResponse"];
var msg = new HttpResponseMessage
{
Content = new StringContent(payloadResponse.ToString(), Encoding.UTF8, "application/json")
};
This is the content of the PayloadResponse I want to convert to an HttpResponse so that I can parse out the response body in a clean way:

If I understand correctly you just want to "parse out the response body in a clean way".
You are trying to convert this to an HttpResponseMessage because you think that will line everything up for you. This is a distraction, it makes it sound like you want to create a response and forward it on, but all you really want is the payload to be parsed into a usable format.
Correct me if I'm wrong.
To parse out that payload you can split that string on the newline character (/u000a), remove the extraneous & and parse the json.
var splitResponse = payloadResponse.ToString().Split(new char[] { '\u000a' });
string body = splitResponse.Last().Substring(1);
JObject job = JObject.Parse(body);
// example
Console.WriteLine(job["messages"]["message"][0]["text"]);
I did not provide classes that you can deserialize this json into because it is an error message and I assume you won't always be dealing with an error. A success response would probably be a different schema. I can't know how to design classes for this from the information you have provided but maybe working with the JObject is adequate.

Make POST request
I'm trying to post to a web form defined as:
<form name="frmdata" method='post' enctype ='multipart/form-data' action ="http://www.rzp.cz/cgi-bin/aps_cacheWEB.sh">
<input type ="hidden" name ="VSS_SERV" value="ZVWSBJXML">
<input type="file" name="filename">
<input type ='submit' name ='x' value ='ODESLI'>
</form>
There is some additional documentation on the form here:
http://www.rzp.cz/docs/RZP02_XML_28.pdf
My latest try:
using (WebClient client = new WebClient())
{
NameValueCollection vals = new NameValueCollection();
vals.Add("VSS_SERV", "ZVWSBJXML");
string filecontent = #"<?xml version=""1.0"" encoding=""ISO-8859-2""?>";
filecontent = filecontent + #"

filecontent = filecontent + #"

filecontent = filecontent + #"</VerejnyWebDotaz>";
vals.Add("filename", filecontent);
client.Headers["ContentType"] = "multipart/form-data";
byte[] responseArray = client.UploadValues(#"http://www.rzp.cz/cgi-bin/aps_cacheWEB.sh", "POST", vals);
string str = Encoding.ASCII.GetString(responseArray);
}
But I can't get past this error:
<KodChyby>-1</KodChyby> (the xml filename does not contain xml defined by namespace)
How can I send this xml data to the form or rather there is a working form - http://stuff.petrovsky.cz/subdom/stuff/RZP/rzp-test-form.php - how to call and catch xml data? I would like to do the same request and get xml.
Using System.Net.Http I was able to construct the form request as a proof of concept using MultipartFormDataContent
Now initially when I tested it, I received 403 Forbidden response but I guessed that was to be expected given my location and that the endpoint might be region locked.
Raw Fiddler response
HTTP/1.1 403 Forbidden
Date: Sat, 27 Oct 2018 01:37:09 GMT
Server: IIS
Content-Length: 225
Keep-Alive: timeout=5, max=100
Connection: Keep-Alive
Content-Type: text/html; charset=iso-8859-1
<!DOCTYPE HTML PUBLIC "-//IETF//DTD HTML 2.0//EN">

<h1>Forbidden</h1>
<p>You don't have permission to access /cgi-bin/aps_cacheWEB.sh
on this server.</p>
</body></html>
I was wrong and the forbidden appeared to be the default response for bad requests as you commented that you received the same forbidden error from within the region. So back to the drawing board I went.
I then copied the example HTML form locally and then proceeded to compare the requests from the form (which did actually work) and my code. Gradually making changes to match I was finally able to get a 200 OK response, but the body of the response was empty.
Apparently there was an issue with the server interpreting the boundary in the content type header if it is wrapped in quotes boundary="...".
After more adjustments it then started returning a message based on the content dispositions generated.
HTTP/1.1 200 OK
Date: Sat, 27 Oct 2018 19:55:11 GMT
Server: IIS

Multiple definitions of VSS_SERV encountered in input.
If you're trying to do this intentionally (such as with select),
the variable must have a "List" suffix.
So it turns out that the XML API is expecting the request to be in a very specific format. Deviate from that and the request fails.
The MultipartFormDataContent was not generating the request correctly and this caused the server to not behave as expected. Other headers were being placed before the Content-Disposition headers of the parts and the Content-Disposition parameters were also not being enclosed in quotes. So by not including the content-type it in the parts and making sure the content-disposition headers were generated correctly eventually fixed the problem.
It is important to note the order of how the headers are added to the content so that the Content-Disposition header is set first for each part.
Working Code that generates the request in the desired format and gets the XML data.
[Test]
public async Task Post_Form() {
//Arrange
var stream = getXml();
var fileContent = new StreamContent(stream);
fileContent.Headers.ContentDisposition = new ContentDispositionHeaderValue("form-data") {
Name = #"""filename""",
FileName = #"""req-details.xml""",
};
fileContent.Headers.ContentType = new MediaTypeHeaderValue("text/xml");
var stringContent = new ByteArrayContent(Encoding.UTF8.GetBytes("ZVWSBJXML"));
stringContent.Headers.ContentDisposition = new ContentDispositionHeaderValue("form-data") {
Name = #"""VSS_SERV""",
};
//could have let system generate it but wanteed to rule it out as a problem
var boundary = "---------------------------" + DateTime.Now.Ticks.ToString("x", NumberFormatInfo.InvariantInfo);
var form = new MultipartFormDataContent(boundary);
//FIX: boundary quote issue
var contentType = form.Headers.ContentType.Parameters.First(o => o.Name == "boundary");
contentType.Value = contentType.Value.Replace("\"", String.Empty);
form.Add(stringContent);
form.Add(fileContent);
//var data = await form.ReadAsStringAsync(); //FOR TESTING PORPOSES ONLY!!
var client = createHttpClient("http://www.rzp.cz/");
//Act
var response = await client.PostAsync("cgi-bin/aps_cacheWEB.sh", form);
var body = await response.Content.ReadAsStringAsync();
//Assert
response.IsSuccessStatusCode.Should().BeTrue();
body.Should().NotBeEmpty();
var document = XDocument.Parse(body); //should be valid XML
document.Should().NotBeNull();
}
The code above generated the following request, which I extracted using fiddler (Pay close attention to the working format)

From there it should be small work to parse the resulting XML as needed.

var doc = XDocument.Parse(xml);//basically to validate XML
var stream = new MemoryStream();
doc.Save(stream);
stream.Position = 0;
return stream;
}
Was gradually able to whittle down the headers needed for a successful request after find the match that worked. Try removing others gradually to test if more can be removed safely to reduce the amount of unnecessary code needed.
private static HttpClient createHttpClient(string baseAddress) {
var handler = createHandler();
var client = new HttpClient(handler);
client.BaseAddress = new Uri(baseAddress);
client.DefaultRequestHeaders.Accept.Clear();
client.DefaultRequestHeaders.TryAddWithoutValidation("User-Agent", "System.Net.Http.HttpClient");
client.DefaultRequestHeaders.TryAddWithoutValidation("Accept-Language", "en-US,en;q=0.9");
client.DefaultRequestHeaders.TryAddWithoutValidation("Accept", "text/xml,application/xml");
client.DefaultRequestHeaders.ExpectContinue = false;
client.DefaultRequestHeaders.ConnectionClose = false;
client.DefaultRequestHeaders.CacheControl = new CacheControlHeaderValue() {
MaxAge = TimeSpan.FromSeconds(0)
};
return client;
}

var handler = new HttpClientHandler();
// if the framework supports automatic decompression set automatic decompression
if (handler.SupportsAutomaticDecompression) {

}
return handler;
}
While I chose to use the asynchronous API of System.Net.Http, I found a similar question
Reference UploadFile with POST values by WebClient
With an answer that was done using WebClient that could be adapted to your question so that a request can be constructed similar to what was produced above.
I tried testing that one as well but got into the same forbidden error. Now that the correct format is know you should also be able to correctly craft a working request using WebClient/WebRequest
Web api error 500 starting from usermanager
First of all, I would like to apologize for my really bad english, if something is not understandable, then reask please.
When I try POST with /api/account/regapi in Swagger then with too short password it gives error 200, but with correct length it gives error 500, while debugging it shows correct parameters at AuthDTO model, but still shows error 500 with correct data.
Response header returned by false data(incorrect password length):
{
"$id": "1",
"succeeded": false,
"errors": [
{
"$id": "2",
"code": "PasswordTooShort",
"description": "Passwords must be at least 6 characters."
}
]
}

How to call Web API (App Service) remotely
I need to call an API from AppService by uri.
This is my API:
public ApiOutputBase Test_AddStudent(string name, int age, string address)
{
return new ApiOutputBase
{
Result = new Result { Status = true, Message = "OK,Test_AddStudent Done!" },
OuputValues = new List<object>() { name, age, address }
};
}
I use this Function to call it:
public async Task<bool> TestCallApi()
{
var client = new HttpClient { BaseAddress = new Uri("http://localhost/") };
client.DefaultRequestHeaders.Accept.Clear();
client.DefaultRequestHeaders.Accept.Add(new MediaTypeWithQualityHeaderValue("application/json"));
var testJson = "{\r\n \"name\": \"MyName\",\r\n \"age\": 25,\r\n \"address\": \"MyAddress\"\r\n}";
HttpResponseMessage response = await client.PostAsync("api/services/myApp/commonLookup/Test_AddStudent", new StringContent(testJson));
// Call api success
if (response.IsSuccessStatusCode)
{
}
return true;
}
I used Swagger to call Test_AddStudent successfully. The testJson was copied from Swagger when I call Test_AddStudent successfully.
After that, I used Swagger to call TestCallApi without any error, but when I tried to debug the value of HttpResponseMessage, it showed this error:
{
StatusCode: 400,
ReasonPhrase: 'Bad Request',
Version: 1.1,

}
}
Have I missed something?
I finally found the root cause: I passed the wrong input to the api:
Wrong:
var testJson = "{\r\n \"name\": \"MyName\",\r\n \"age\": 25,\r\n \"address\": \"MyAddress\"\r\n}";
HttpResponseMessage response = await client.PostAsync("api/services/myApp/commonLookup/Test_AddStudent", new StringContent(testJson));
Correct:
HttpResponseMessage response = await client.PostAsync("api/services/myApp/commonLookup/Test_AddStudent?name=MyName&age=25&address=MyAdress", "");

ReadAsAsync<T> attempts to deserialize the response to type T. In this case, you're saying you want to deserialize JSON to a string, which doesn't really make sense. Either use a type matching the response (i.e. a custom data structure containing Header, Token, etc.) or use ReadAsStringAsync() if you really want to get a string.
YouTube API Video Upload Parse Error in C#

Anyone have any ideas?
The parse error is due to True being written with a big T. (using the beta library is not an option for me becuase of Unity. .NET 2.0..)
