HTTP request for a client connection.
To set up a request, set the headers using the headers property provided in this class and write the data to the body of the request. HttpClientRequest is an IOSink. Use the methods from IOSink, such as writeCharCode(), to write the body of the HTTP request. When one of the IOSink methods is used for the first time, the request header is sent. Calling any methods that change the header after it is sent throws an exception.
When writing string data through the IOSink the encoding used is determined from the "charset" parameter of the "Content-Type" header.
HttpClientRequest request = ...
request.headers.contentType
= new ContentType("application", "json", charset: "utf-8");
request.write(...); // Strings written will be UTF-8 encoded.
If no charset is provided the default of ISO-8859-1 (Latin 1) is be used.
HttpClientRequest request = ...
request.headers.add(HttpHeaders.CONTENT_TYPE, "text/plain");
request.write(...); // Strings written will be ISO-8859-1 encoded.
An exception is thrown if you use an unsupported encoding and the
write()
method being used takes a string parameter.
- Implements
Properties
- bufferOutput → bool
-
read / write
Get or set if the HttpClientRequest should buffer output.…
- connectionInfo → HttpConnectionInfo
-
read-only
Get information about the client connection. Returns
null
if the socket is not available. - contentLength → int
-
read / write
Gets and sets the content length of the request. If the size of the request is not known in advance set content length to -1, which is also the default.
-
read-only
Cookies to present to the server (in the 'cookie' header).
- done → Future<HttpClientResponse>
-
read-only
A
HttpClientResponse
future that will complete once the response is available. If an error occurs before the response is available, this future will complete with an error. - encoding → Encoding
-
read / write, inherited
The Encoding used when writing strings. Depending on the underlying consumer this property might be mutable.
- followRedirects → bool
-
read / write
Set this property to
true
if this request should automatically follow redirects. The default istrue

-
read-only
Returns the client request headers.…
- maxRedirects → int
-
read / write
Set this property to the maximum number of redirects to follow when followRedirects is
true
. If this number is exceeded theonError
callback will be called with a RedirectException.… - method → String
-
read-only
The method of the request.
- persistentConnection → bool
-
read / write
Gets and sets the requested persistent connection state.…
- uri → Uri
-
read-only
The uri of the request.
