Httplib2：一個全面的 Python HTTP 客戶端

一個全面的HTTP客戶端庫，支持很多其他的HTTP庫所擁有的特性。需要Python2.3或更高版本的運行環境，0.5.0版及其以后包含了對Python3的支持。

詳細特性：

HTTP and HTTPS

HTTPS support is only available if the socket module was compiled with SSL support.

Keep-Alive

Supports HTTP 1.1 Keep-Alive, keeping the socket open and performing multiple requests over the same connection if possible.

Authentication

The following types of HTTP Authentication are supported. These can be used over both HTTP and HTTPS.

• Digest
• Basic
• WSSE
• HMAC Digest
• Google Account Authentication

Caching

The module can optionally operate with a private cache that understands the Cache-Control: header and uses both the ETag and Last-Modified cache validators.

All Methods

The module can handle any HTTP request method, not just GET and POST.

Redirects

Automatically follows 3XX redirects on GETs.

Compression

Handles both 'deflate' and 'gzip' types of compression.

Lost update support

Automatically adds back ETags into PUT requests to resources we have already cached. This implements Section 3.2 of Detecting the Lost Update Problem Using Unreserved Checkout.

Unit Tested

A large and growing set of unit tests.
