Http Client¶

import "std/net/http-client";

HttpClient struct¶

A blocking HTTP/1.1 client, built on the plain TCP sockets of "std/net/socket".

Every request opens its own connection, announces Connection: close and closes the connection again once the response has been read, so no connection state survives a call. Responses framed by Content-Length, by the chunked transfer coding, or by the connection close of an HTTP/1.0 server are all understood.

There is no TLS underneath, so https URLs are rejected instead of being silently downgraded. Use the libcurl bindings in "std/bindings/libcurl" when a request has to go over https.

Fields¶

1

public p HttpClient.ctor()
