411 Length Required
The HTTP 411 Length Required
client error response status code indicates that the server refused to accept the request without a defined Content-Length
header.
Note: When sending data in a series of chunks, the Content-Length
header is omitted, and at the beginning of each chunk, the length of the current chunk needs to be included in hexadecimal format.
See Transfer-Encoding
for more details.
Status
http
411 Length Required
Examples
Chunked POST request
The following request is sent chunked, which is the default method of sending data in some cases, such as when writing to streams:
http
POST /translate/de HTTP/1.1
Host: api.example.com
Content-Type: application/json
Transfer-encoding: chunked
2C
{"text": "Hurry up, Ayşe is hungry!"}
0
In this case, the server is expecting a request in one part with a Content-Length
header and returns a 411 response:
http
HTTP/1.1 411 Length Required
Content-Type: application/json
Content-Length: 110
{
"message": "Requests must have a content length header.",

}
