EndeavourOS/Arch x86_64, requests v2.1.3.
When sending a POST with a body, a Content-Length header is not automatically added, even when posting a string (which is not chunked and has a known length).
import std;
import requests;
void main()
{
auto res = postContent("http://httpbin.org/post", "Hello, World!");
writeln(res);
}{
"args": {},
"data": "Hello, World!",
"files": {},
"form": {},
"headers": {
"Accept-Encoding": "gzip,deflate",
"Content-Type": "application/octet-stream",
"Host": "httpbin.org",
"Transfer-Encoding": "chunked",

},

"url": "http://httpbin.org/post"
}This is not a problem with httpbin.org, but some services do require the header. An example is batsign.me, with which you can mail small reports to yourself by sending a quick POST to a custom URL.
import std;
import requests;
void main()
{
auto res = postContent("https://batsign.me/at/user@host.com/asdfasdf", "Warning: server is down");
writeln(res);

It can be worked around by using Request.post instead of postContent and manually adding the header.
import std;
import requests;
void main()
{
enum body_ = "Warning: server is down";
auto rq = Request();
rq.addHeaders([ "Content-Length": body_.length.to!string ]);
auto res = rq.post("https://batsign.me/at/user@host.com/asdfasdf", body_);
writeln(cast(string)res.responseBody);
}Looking through the examples in the readme, it seems like the length is properly calculated and added if you use multi-part forms? (I didn't test and verify)
But it doesn't for simple strings at least. Is this intended behaviour?
