Build Status

HTTP requests library with goals:

  • small memory footprint
  • performance
  • simple, high level API

API docs: Wiki

In simplest scenario you just need to fetch and process document from remote site. In this case you can call getContent

import std.stdio;
import std.algorithm;
import requests;

pragma(lib, "ssl");
pragma(lib, "crypto");

void main() {
    writeln(
        getContent("https://httpbin.org/")
        .splitter('\n')
        .filter!("a.length>0")
        .count
    );
}

getContent returns Buffer, filled with data. Buffer looks like Appender!ubyte (it have method data()), but also support many Range operations.

When you need access to response code, you have to use Request and Response structures:

Request rq = Request();
Response rs = rq.get("https://httpbin.org/");
assert(rs.code==200);

For anything other than default, you can configure Request structure for keep-alive, redirects, headers, or for different io-buffer and maximum sizes of response headers and body.

For example to authorize with Basic authorization use next code:

    rq = Request();
    rq.authenticator = new BasicAuthentication("user", "passwd");
    rs = rq.get("http://httpbin.org/basic-auth/user/passwd");

Here is short descrition of some Request options:

nametypemeaningdefault
keepAliveboolrequest keepalive connectionfalse
maxRedirectsuintmaximum redirect depth10
maxHeadersLengthsize_tmax.acceptable response headers length32KB
maxContentLengthsize_tmax.acceptable content length5MB
timeoutDurationtimeout on connect or data transfer30.seconds
bufferSizesize_tsocket io buffer size16KB
verbosityuintverbosity level (0, 1 or 2)0
proxystringurl of the http proxynull
headersstring[string]additional headersnull

Usage example:

 auto rq = Request();
 auto rs = rq.get("http://httpbin.org/");
 writeln(rs.responseBody.data!string);

 rq.keepAlive = true;
 rs = rq.post("http://httpbin.org/post", `{"a":"b", "c":[1,2,3]}`, "application/json");
 assert(rs.code==200);

 auto f = File("tests/test.txt", "rb");
 rs = rq.post("http://httpbin.org/post", f.byChunk(3), "application/octet-stream");
 assert(rs.code==200);
 auto data = parseJSON(rs.responseBody.data).object["data"].str;
 assert(data=="abcdefgh\n12345678\n");
 f.close();

For Windows users

Requests distributed with binary ssl and crypto libraries. These libararies were downloaded from https://slproweb.com/products/Win32OpenSSL.html (full version) and converted using "implib /system" http://ftp.digitalmars.com/bup.zip. If you know better way to link windows libraries, please, let me know.
