http_client 1.2.2+2

Platform-independent HTTP client #

A platform-independent HTTP client API supporting browser, console, and curl (for SOCKS proxy). Planned platforms: Fetch API, node_io.

Usage: #

To develop your platform-agnostic library, use only the base import:

import 'package:http_client/http_client.dart' as http;

class MyServiceClient {
  final http.Client httpClient;

For console apps:

import 'package:http_client/console.dart' as http;

main() async {
  final client = http.ConsoleClient();
  // use the client, eg.:
  // new MyServiceClient(client)
  await client.close();

For browser use, only change the first import:

import 'package:http_client/browser.dart' as http;

main() {
  final client = http.BrowserClient();
  // use the client, eg.:
  // new MyServiceClient(client)
  await client.close();

Changelog #

1.2.2+2 #

  • Fix NPE in UpdatingClient.

1.2.2+1 #

  • Fix NPE.

1.2.2 #

  • Simplify timeout code in ConsoleClient and BrowserClient.
  • Separate cleanup with Timer in UpdatingClient.

1.2.1 #

  • Fix timeout handling in ConsoleClient.

1.2.0 #


  • Headers forces keys to be lowercase (part of the HTTP/2 spec).
  • Request validates arguments differently, may not throw exception where previously thrown (e.g. allows Stream<List<int>> as body).

New features:

  • Request constructor now accepts:
    • form (url-encoded body and also sets content-type header)
    • json (json-encoded body and also sets content-type header)
    • cookies (sets cookie header)

1.1.0 #

  • Updated sources: removed new keyword.
  • Request.timeout for limiting the timeout at the lowest level of the network, other framework-related operations do not count against it.

1.0.4 #

  • Request.change to override url, headers or body. addHeader to extend current headers.

1.0.3 #

  • CloseClientFn in UpdatingClient.

1.0.2 #

  • Class-level invalidateOnError and forceCloseOnError for UpdatingClient.
  • TrackingClient.toString() forwards to delegate client.

1.0.1 #

  • Automatic Content-Length header when body is specified (in ConsoleClient).

1.0.0+1 #

  • Fix: cleanup of past clients in UpdatingClient.

1.0.0 #


  • Request.body is used instead of bodyStream and bodyBytes.
  • Stream<List<int>> inputs are no longer supported, use restartable FutureOr<Stream<List<int>>> StreamFn() instead.
  • Single Response constructor, body become an untyped holder (use bodyAsStream if migrating uses).

Other updates

  • Explicit expiration, and optional on-exception expiration in UpdatingClient.
  • Support form-encoded values as request body.
  • Support File with Request.body on ConsoleClient.
  • Support native request types with Request.body and Response.body on BrowserClient.

0.6.0 #

  • Support close({bool force}) on the API (and on console).
  • Support Response.done to indicate when the underlying input stream has been read and completed.
  • TrackingClient to keep track of ongoing and completed request count (with content read support).
  • UpdatingClient to automatically recreate client resources (or rotate proxies) after some use.

0.5.1 #

  • Code update: Dart 2.1(-dev) lints.

0.5.0 #

  • Dart 2

0.4.4+1 #

  • Fix header override bug.

0.4.3 #

  • Record redirect info (when available).
  • Response.requestAddress to have the address where the request was opened at.
  • BREAKING: Response.remoteAddress renamed to responseAddress.

0.4.2 #

  • Better Headers handling.
  • Request properties: persistentConnection, followRedirects, maxRedirects.
  • ConsoleClient properties: idleTimeout, maxConnectionsPerHost, autoUncompress, userAgent.
  • Response.remoteAddress (in ConsoleClient).

0.4.1 #

  • Enabled Dart2 Preview for analysis.

0.4.0 #

  • Fix deprecated API use.
  • Fix header wrapping in requests.
  • Default header values in ConsoleClient.

0.3.1 #

  • Added http proxy option to the console client.

0.3.0 #

  • Removed dependency on http package.

0.2.2 #

  • Add executor support to rate-limit the clients.

0.2.1 #

  • Add curl support.

0.2.0 #

Breaking changes:

  • instead of exporting the http package, http_client provides its own API

    • console and browser clients continue to use the http package
    • preparation to support node_io for apps that want to be packaged as a single binary (e.g. .exe)
    • preparation to support the Fetch API (e.g. in service workers)
  • removed the awkward newHttpClient() methods.

0.1.0 #

  • Exporting classes from the http package (version: ^0.1.13).

0.1.0+1 #

  • Exporting streaming request and response.
