Hello dear community,
I am currently in the process of programming a WebRequest from AX2012.
The requirement is that I pass the Content-Type as "application/json;charset=UTF-8.
Unfortunately it seems that AX ignores the .set_ContentType.
We wrote a small test service, which as an answer shows me what the original request was.
Here are some code examples.
private void requestService()
{
System.String response = "";
System.Net.HttpWebRequest httpRequest = null;
System.Net.HttpWebResponse httpResponse = null;
System.Net.WebHeaderCollection httpHeader = null;
CLRObject clro = null;
System.IO.Stream stream = null;
System.IO.StreamReader streamReader = null;
System.Byte[] bytes = null;
System.Byte[] byteArray = null;
System.Text.Encoding encoding = null;
boolean ret = true;
str byteStr;
byteStr = strfmt("%1:%2", rampParameter.Username, rampParameter.Password);
try
{
new InteropPermission(InteropKind::ClrInterop).assert();
httpHeader = new System.Net.WebHeaderCollection();
clro = System.Net.WebRequest::Create(this.getRequestUrl());
httpRequest = clro;
httpRequest.set_Method("POST");
httpRequest.set_ContentType(@"application/json;charset=UTF-8");
encoding = System.Text.Encoding::get_UTF8();
byteArray = encoding.GetBytes(byteStr);
byteStr = System.Convert::ToBase64String(byteArray);
httpHeader.Add("Authorization", 'Basic ' + byteStr);
httpRequest.set_Headers(httpHeader);
bytes = encoding.GetBytes(this.buildJsonString());
httpRequest.set_ContentLength(bytes.get_Length());
stream = httpRequest.GetRequestStream();
stream.Write(bytes,0,bytes.get_Length());
stream.Close();
httpResponse = httpRequest.GetResponse();
stream = httpResponse.GetResponseStream();
streamReader = new System.IO.StreamReader(stream);
response = streamReader.ReadToEnd();
CodeAccessPermission::revertAssert();
}
catch(Exception::CLRError)
{
ret = false;
throw error(AifUtil::getClrErrorMessage());
}
}In the example, in line 26, I set the ContentType via the request method.
But that doesn't seem to work.
As a result I get the response:
{"Headers":{"Authorization":["Basic XXXX"],"Connection":["Keep-Alive"],"Content-Length":["65"],"Expect":["100-continue "],"Host":["iis2016-01:4747"]},"Query":{"value":"","hasValue":false},"RouteValues":{"action":"Post", "controller":"Values"},"Body":"{\"gate\":\"10\",\"direction\":\"UNLOAD\",\"start\":\"2022-09 -08T12:14:14Z\"}"}
We tested the service that we programmed, if we send a request via Postman, we get the corresponding content type back.
We then tried, instead of
httpRequest.set_ContentType(@"application/json;charset=UTF-8");
to use the following code and put the type directly in the header:
httpHeader.Add("content-type",@"application/json;charset=UTF-8");
But then we get the following Infolog error message:
"The 'content-type' header must be modified with the appropriate property or method.
Parameter name: name"
Do any of you see the error in the code? We're currently a bit clueless.
Or is that perhaps a mistake by AX?
i'm trying to post a invoice.
