I am trying to read stream data from HttpRequest.Body but I am getting empty string.
The request is send here from .net project



        HttpWebRequest request = null;
Uri uri = new Uri(**Endpoint**);
UTF8Encoding encoding = new UTF8Encoding();
byte bytes = encoding.GetBytes(message);
request = (HttpWebRequest)WebRequest.Create(uri);
request.Method = "POST";
request.ContentType = "application/x-www-form-urlencoded";
request.ContentLength = bytes.Length;
request.UseDefaultCredentials = true;
using (Stream writeStream = request.GetRequestStream()) {
writeStream.Write(bytes, 0, bytes.Length);
}
try {
HttpWebResponse response = (HttpWebResponse)request.GetResponse();
if (response.StatusCode == HttpStatusCode.OK) {
return true;
} else {
return false;
}
} catch {
lock (endpointLock) {
_pushHttpEndpoint = null;
}
return false;
}


The request is send here.This is .net core 2.1 application. I am trying to read the data in request body but that is returning empty



    [HttpPost]
public string Post()
{
var bodyStr = "";
var req = HttpContext.Request;
req.EnableRewind();
using (StreamReader reader
= new StreamReader(req.Body, Encoding.UTF8, true, 1024, true))
{
bodyStr = reader.ReadToEnd();
}

req.Body.Seek(0, SeekOrigin.Begin);
//do other stuff
return bodyStr;
}


Can someone please help me with this.
We are in position where we cannot change the .net solution code. Any changes should be done in .net core solution side. We are trying to fit the new api in place of existing Endpoint. :(

          Your type is "type is application/x-www-form-urlencoded" , so use [FromForm] attribute . Code below is for your reference :



          .Net project :



                  HttpWebRequest request = null;
          Uri uri = new Uri("https://localhost:44365/Home/Post");
          UTF8Encoding encoding = new UTF8Encoding();
          var postData = "thing1=hello";
          postData += "&thing2=world";
          byte bytes = encoding.GetBytes(postData);
          request = (HttpWebRequest)WebRequest.Create(uri);
          request.Method = "POST";
          request.ContentType = "application/x-www-form-urlencoded";
          request.ContentLength = bytes.Length;
          request.UseDefaultCredentials = true;
          using (Stream writeStream = request.GetRequestStream())
          {
          writeStream.Write(bytes, 0, bytes.Length);
          }
          try
          {
          HttpWebResponse response = (HttpWebResponse)request.GetResponse();
          if (response.StatusCode == HttpStatusCode.OK)
          {
          //return true;
          }
          else
          {
          // return false;
          }
          }
          catch(Exception e)
          {

          }


          On your .net Core Project :



              [HttpPost]
          public string Post([FromForm]AcceptValue acceptValue)
          {

          //do other stuff
          return "";
          }

          public class AcceptValue {
          public string thing1 { get; set; }

          public string thing2 { get; set; }
          }

          • Actually we are trying to hack our code. The problem is that the data cannot be sent in this way. var postData = "thing1=hello"; postData += "&thing2=world"; .Net code is the old one and we are in situation not to change that. Data that is sent can be any format and we need that in .net core solution. Any changes should be done in .net core solution side. We are in tricky position. :(

          You should use the [FromBody] attribute.



          It will be this:



          [HttpPost]
          public string Post([FromBody] object body) {
          // do stuff here
          }

            This doesnt help. [FromBody] for "application/x-www-form-urlencoded" request gives 415 unsupported media type error in .net core.

          • @Amrutha , FromBody is used for json type , you should use FromForm if the type is application/x-www-form-urlencoded .See my reply

          Your type is "type is application/x-www-form-urlencoded" , so use [FromForm] attribute . Code below is for your reference :



          .Net project :



                  HttpWebRequest request = null;
          Uri uri = new Uri("https://localhost:44365/Home/Post");
          UTF8Encoding encoding = new UTF8Encoding();
          var postData = "thing1=hello";
          postData += "&thing2=world";
          byte bytes = encoding.GetBytes(postData);
          request = (HttpWebRequest)WebRequest.Create(uri);
          request.Method = "POST";
          request.ContentType = "application/x-www-form-urlencoded";
          request.ContentLength = bytes.Length;
          request.UseDefaultCredentials = true;
          using (Stream writeStream = request.GetRequestStream())
          {
          writeStream.Write(bytes, 0, bytes.Length);
          }
          try
          {
          HttpWebResponse response = (HttpWebResponse)request.GetResponse();
          if (response.StatusCode == HttpStatusCode.OK)
          {
          //return true;
          }
          else
          {
          // return false;
          }
          }
          catch(Exception e)
          {

          }


          On your .net Core Project :



              [HttpPost]
          public string Post([FromForm]AcceptValue acceptValue)
          {

          //do other stuff
          return "";
          }

          public class AcceptValue {
          public string thing1 { get; set; }

          public string thing2 { get; set; }
          }

          • Actually we are trying to hack our code. The problem is that the data cannot be sent in this way. var postData = "thing1=hello"; postData += "&thing2=world"; .Net code is the old one and we are in situation not to change that. Data that is sent can be any format and we need that in .net core solution. Any changes should be done in .net core solution side. We are in tricky position. :(

          You should use the [FromBody] attribute.



          It will be this:



          [HttpPost]
          public string Post([FromBody] object body) {
          // do stuff here
          }

            This doesnt help. [FromBody] for "application/x-www-form-urlencoded" request gives 415 unsupported media type error in .net core.

          • @Amrutha , FromBody is used for json type , you should use FromForm if the type is application/x-www-form-urlencoded .See my reply
