Struct `std.net.curl.HTTP`

HTTP client functionality.


						
				struct HTTP
				;

Properties

Name	Type	Description
`authenticationMethod`[set]	`CurlAuth`	Authentication method as specified in `AuthMethod`.
`caInfo`[set]	`const(char)[]`	Set the CA certificate bundle file to use for SSL peer verification
`connectTimeout`[set]	`Duration`	Set timeout for connecting.
`contentLength`[set]	`ulong`	The content length in bytes when using request that has content e.g. POST/PUT and not using chunked transfer. Is set as the "Content-Length" header. Set to ulong.max to reset to chunked transfer.
`dataTimeout`[set]	`Duration`	Set timeout for activity on connection.
`defaultUserAgent`[get]	`string`	The default "User-Agent" value send with a request. It has the form "Phobos-std.net.curl/PHOBOS_VERSION (libcurl/CURL_VERSION)"
`dnsTimeout`[set]	`Duration`	DNS lookup timeout.
`isStopped`[get]	`bool`	True if the instance is stopped. A stopped instance is not usable.
`localPort`[set]	`ushort`	Set the local outgoing port to use.
`localPortRange`[set]	`ushort`	Set the local outgoing port range to use. This can be used together with the localPort property.
`maxRedirects`[set]	`uint`	Set max allowed redirections using the location header. uint.max for infinite.
`method`[get, set]	`HTTP.Method`	HTTP method used.
`netInterface`[set]	`const(char)[]`	The network interface to use in form of the the IP of the interface.
`onProgress`[set]	`int delegate(ulong, ulong, ulong, ulong)`	Register an event handler that gets called to inform of upload/download progress.
`onReceive`[set]	`ulong delegate(ubyte[])`	The event handler that receives incoming data. Be sure to copy the incoming ubyte[] since it is not guaranteed to be valid after the callback returns.
`onReceiveHeader`[set]	`void delegate(const(char[]), const(char[]))`	Set the event handler that receives incoming headers.
`onReceiveStatusLine`[set]	`void delegate(HTTP.StatusLine)`	Callback for each received StatusLine.
`onSend`[set]	`ulong delegate(void[])`	The event handler that gets called when data is needed for sending. The length of the `void[]` specifies the maximum number of bytes that can be sent.
`operationTimeout`[set]	`Duration`	Set maximum time an operation is allowed to take. This includes dns resolution, connecting, data transfer, etc.
`postData`[set]	`const(void)[]`	Specifying data to post when not using the onSend callback.
`postData`[set]	`const(char)[]`	Specifying data to post when not using the onSend callback.
`proxy`[set]	`const(char)[]`	Proxy
`proxyPort`[set]	`ushort`	Proxy port
`proxyType`[set]	`CurlProxy`	Proxy type
`responseHeaders`[get]	`string[string]`	The headers read from a successful response.
`statusLine`[get]	`HTTP.StatusLine`	HTTP status line of last response. One call to perform may result in several requests because of redirection.
`tcpNoDelay`[set]	`bool`	Set the tcp no-delay socket option on or off.
`url`[set]	`const(char)[]`	The URL to specify the location of the resource.
`verbose`[set]	`bool`	Set verbose. This will print request information to stderr.

Methods

Name	Description
`addRequestHeader`	Add a header e.g. "X-CustomField: Something is fishy".
`clearAllCookies`	Clear all cookies.
`clearRequestHeaders`	Clear all outgoing headers.
`clearSessionCookies`	Clear session cookies.
`dup`
`flushCookieJar`	Flush cookie jar to disk.
`getTiming`	Get various timings defined in `CurlInfo`. The value is usable only if the return value is equal to `CurlError.ok`.
`opCall`	Constructor taking the url as parameter.
`opCall`
`perform`	Perform a http request.
`setAuthentication`	Set the user name, password and optionally domain for authentication purposes.
`setCookie`	Set the active cookie string e.g. "name1=value1;name2=value2"
`setCookieJar`	Set a file path to where a cookie jar should be read/stored.
`setPostData`	Specify data to post when not using the onSend callback, with user-specified Content-Type.
`setProxyAuthentication`	Set the user name and password for proxy authentication.
`setTimeCondition`	Set time condition on the request.
`setUserAgent`	Set the value of the user agent request header field.
`shutdown`	Stop and invalidate this instance.

Inner structs

Name	Description
`StatusLine`	HTTP status line ie. the first line returned in an HTTP response.

Enums

Name	Description
`Method`	The standard HTTP methods : RFC2616 Section 5.1.1

Aliases

Name	Description
`AuthMethod`	Authentication method equal to `CurlAuth`
`CurlProxy`	Type of proxy
`requestAbort`	Value to return from onSend delegate in order to abort a request
`requestPause`	Value to return from `onSend`/`onReceive` delegates in order to pause a request
`TimeCond`	Time condition enumeration as an alias of `CurlTimeCond`

Example

Get with custom data receivers:

import std.net.curl, std.stdio;

auto http = HTTP("https://dlang.org");
http.onReceiveHeader =
    (in char[] key, in char[] value) { writeln(key ~ ": " ~ value); };
http.onReceive = (ubyte[] data) { /+ drop +/ return data.length; };
http.perform();

Put with data senders:

import std.net.curl, std.stdio;

auto http = HTTP("https://dlang.org");
auto msg = "Hello world";
http.contentLength = msg.length;
http.onSend = (void[] data)
{
    auto m = cast(void[]) msg;
    size_t len = m.length > data.length ? data.length : m.length;
    if (len == 0) return len;
    data[0 .. len] = m[0 .. len];
    msg = msg[len..$];
    return len;
};
http.perform();

Tracking progress:

import std.net.curl, std.stdio;

auto http = HTTP();
http.method = HTTP.Method.get;
http.url = "http://upload.wikimedia.org/wikipedia/commons/" ~
           "5/53/Wikipedia-logo-en-big.png";
http.onReceive = (ubyte[] data) { return data.length; };
http.onProgress = (size_t dltotal, size_t dlnow,
                   size_t ultotal, size_t ulnow)
{
    writeln("Progress ", dltotal, ", ", dlnow, ", ", ultotal, ", ", ulnow);
    return 0;
};
http.perform();
