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.

HttpClientRequest()

Properties

bufferOutput → bool

Get or set if the HttpClientRequest should buffer output.

read / write
connectionInfo → HttpConnectionInfo

Get information about the client connection. Returns null if the socket is not available.

read-only
contentLength → int

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 / write
cookies → List<Cookie>

Cookies to present to the server (in the 'cookie' header).

read-only
done → Future<HttpClientResponse>

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.

read-only
followRedirects → bool

Set this property to true if this request should automatically follow redirects. The default is true.

read / write
headers → HttpHeaders

Returns the client request headers.

read-only
maxRedirects → int

Set this property to the maximum number of redirects to follow when followRedirects is true. If this number is exceeded the onError callback will be called with a RedirectException.

read / write
method → String

The method of the request.

read-only
persistentConnection → bool

Gets and sets the requested persistent connection state.

read / write
uri → Uri

The uri of the request.

read-only
encoding → Encoding

The Encoding used when writing strings. Depending on the underlying consumer this property might be mutable.

read / write, inherited
hashCode → int

The hash code for this object.

read-only, inherited
runtimeType → Type

A representation of the runtime type of the object.

read-only, inherited

Operators

operator ==(other) → bool

The equality operator.

inherited

Methods

close() → Future<HttpClientResponse>

Close the request for input. Returns the value of done.

add(List<int> data) → void

Adds byte data to the target consumer, ignoring encoding.

inherited
addError(error, [ StackTrace stackTrace ]) → void

Passes the error to the target consumer as an error event.

inherited
addStream(Stream<List<int>> stream) → Future

Adds all elements of the given stream to this.

inherited
flush() → Future

Returns a Future that completes once all buffered data is accepted by the underlying StreamConsumer.

inherited
noSuchMethod(Invocation invocation) → dynamic

Invoked when a non-existent method or property is accessed.

inherited
toString() → String

Returns a string representation of this object.

inherited
write(Object obj) → void

Converts obj to a String by invoking Object.toString and adds the encoding of the result to the target consumer.

inherited
writeAll(Iterable objects, [ String separator = "" ]) → void

Iterates over the given objects and writes them in sequence.

inherited
writeCharCode(int charCode) → void

Writes the character of charCode.

inherited
writeln([Object obj = "" ]) → void

Converts obj to a String by invoking Object.toString and writes the result to this, followed by a newline.
