Webdis - 一個快速的 Redis HTTP 接口

Webdis是一個簡單的 HTTP 服務器。它將操作命令轉發至Redis，然后按你選擇的格式送發請求返回。它用到了 hiredis, jansson, libevent, 和 http-parser這些第三訪包。支持以下特性：

• 支持GET 和 POST，和PUT用于文件上傳
• 默認返回輸出JSON，optional JSONP parameter (?jsonp=myFunction or ?callback=myFunction).
• Raw Redis 2.0 protocol output with .raw suffix
• MessagePack output with .msg suffix
• HTTP 1.1 pipelining (70,000 http requests per second on a desktop Linux machine.)
• Multi-threaded server, configurable number of worker threads.
• WebSocket support (Currently using the “hixie-76” specification).
• Connects to Redis using a TCP or UNIX socket.
• Restricted commands by IP range (CIDR subnet + mask) or HTTP Basic Auth, returning 403 errors.
• Possible Redis authentication in the config file.
• Pub/Sub using Transfer-Encoding: chunked, works with JSONP as well. Webdis can be used as a Comet server.
• Drop privileges on startup.
• Custom Content-Type using a pre-defined file extension, or with ?type=some/thing.
• URL-encoded parameters for binary data or slashes and question marks. For instance, %2f is decoded as / but not used as a command separator.
• Logs, with a configurable verbosity.
• Cross-origin requests, usable with XMLHttpRequest2 (Cross-Origin Resource Sharing - CORS).
• File upload with PUT.
• With the JSON output, the return value of INFO is parsed and transformed into an object.
• Optional daemonize.
• Default root object: Add "default_root": "/GET/index.html" in webdis.json to substitute the request to / with a Redis request.
• HTTP request limit with http_max_request_size (in bytes, set to 128MB by default).
• Database selection in the URL, using e.g. /7/GET/key to run the command on DB 7.
