http-parser.D

http-parser.D = joyent/http-parser in D programming language.

Usage

import std.stdio;
import http.parser.core;
...
auto parser = new HttpParser();
parser.onMessageBegin = (parser) {
	writeln("Message has just begun");
};
parser.onMessageComplete = (parser) {
	writeln("Message has been completed");
};
parser.onUrl = (parser, string data) {
	writeln("Url of HTTP message is: ", data);
};
parser.onStatusComplete = (parser) {
	writeln("HTTP status is complete");
    // if parsing request, this is a good spot to query for:
    if(parser.type == HttpParserType.REQUEST) {
        string method = parser.method; // GET
        writeln("Method: ", method);
    }
    auto version = parser.protocolVersion.toString; // 1.1
};
parser.onHeader = (parser, HttpHeader header) {
	writeln("Parser Header '", header.name, "' with value '", header.value, "'");
};
parser.onBody = (parser, HttpBodyChunk chunk) {
    string isFinal = chunk.isFinal ? "final" : "not final" ;
	writeln(std.string.format("A chunk of the HTTP body has been processed: %s (%s) ", chunk.buffer, isFinal));
};
parser.execute("GET / HTTP 1.1\r");
parser.execute("\n");
parser.execute("FirstHeader: ValueOfFirst Header\r\n");
parser.execute("Content-Length: 3\r\n");
parser.execute("\r\n");
ubyte[] bodyChunk = [1u,2u,3u];
parser.execute(bodyChunk);

Output:

Message has just begun
Url of HTTP message is: /
Parser Header 'FirstHeader' with value 'ValueOfFirst Header'
Parser Header 'Content-Length' with value '3'
A chunk of the HTTP bady has been processed: [1, 2, 3] (is final)
Message has been completed

Uri

Uri parsing is provided by the class http.parser.Uri.

import http.parser : Uri;

//...

Uri uri = new Uri("http://user1:password1@google.com:9000/myResource?indent=1#page_2");
string schema = uri.schema; // -> "http"
string credentials = uri.userInfo; // -> "user1:password1"
string host = uri.host; // -> "google.com"
ushort port = uri.port; // -> 9000
string path = uri.path; // -> "/myResource"
string query = uri.query; // -> "ident=1"
string fragment = uri.fragment; // -> "page_2"

Body Transmission Modes

Once the headers were parsed, HttpParser.transmissionMode can be used to determinate how the body of the message will be transmitted. The values are and will be detected in the following order:

• HttpBodyTransmissionMode.Chunked: Transfer-Encoding header was found in the request.
• HttpBodyTransmissionMode.ContentLength: Content-Length > 0 header was found in the request.
• HttpBodyTransmissionModel.None: No entity expected in the incoming HTTP message.

Building

git clone https://github.com/bithavoc/http-parser.d.git
git submodule update --init
make

An archive will be generated in out/http-parser.a containing joyent/http-parser objects and the http-parser.d object itself.

Examples

Use make examples to compile all the examples. Executables will be generated in out/examples.

Test

make test
