I am defining the Content-Length of an HTTP request but because sometimes it might contain chinese characters when it gets to the response side of things, it gets truncated.

I have been trying to get the right way to set the content-length of a mixed Chinese/Latin String but with no luck. it keeps getting truncated.

headers["Content-Length"] = data.length;   //fails

{ \"query\": \"周杰伦\", \"type\": \"artist\"} //gets truncated


{ \"query\": \"gennaro\", \"type\": \"artist\"} //successful request

Can anyone suggest how to calculate the second string length for the content-length header properly?

NOTE: the body is stringified from JSON before it is sent over.

Thanks

  • And I assume you did `headers["Content-Length"] = data.length; ` AFTER the json_encode – mplungjan Feb 08 '22 at 13:31
  • While I'm not sure what @connexo expects you to do with C# code, your question leaves a bit too much for imagination. How are you sending that data? Are you really expected to set the header yourself? Please provide relevant code portions, preferably an [mre]. – tevemadar Feb 08 '22 at 13:42

The fix this issue , I used TextEncoder which allow me to encode it to utf8 and then count it in the correct way.

let bodyLength = (new TextEncoder().encode(dataBody)).length;
