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 = ...
    = 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.



bufferOutput bool
read / write

Get or set if the HttpClientRequest should buffer output.

connectionInfo HttpConnectionInfo

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.

cookies List<Cookie>

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

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.

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 is true.

headers HttpHeaders

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 the onError callback will be called with a RedirectException.

method String

The method of the request.

persistentConnection bool
read / write

Gets and sets the requested persistent connection state.

uri Uri

The uri of the request.




add(List<int> data) → void

Adds data to the target consumer, ignoring encoding.

addError(error, [StackTrace stackTrace]) → void

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

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

Adds all elements of the given stream to this.

close() → Future<HttpClientResponse>

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

flush() → Future

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

write(Object obj) → void

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

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

Iterates over the given objects and writes them in sequence.

writeCharCode(int charCode) → void

Writes the charCode to this.

writeln([Object obj = ""]) → void

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