Unirest 是一個支持多種開發語言包括：Node、Ruby、Java、PHP、Python、Objective-C、.NET等的輕量級 HTTP 請求客戶端，適用于大部分程序。

• 實現GET, POST, PUT, PATCH, DELETE 請求
• 包括同步和異步（非阻塞）請求
• 支持表單參數，文件上傳和自定義body entities
• 支持gzip
• 支持基本身份驗證本身
• 自定義超時
• 為每個請求定制默認headers（DRY）
• 對JSON響應自動JSON解析成本地對象

以下是Python實現的使用示例

創建請求

使用Unirest使用Python創建請求更簡單：

response = unirest.post("http://httpbin.org/post", headers={ "Accept": "application/json" }, params={ "parameter": 23, "foo": "bar" })

response.code # The HTTP status code
response.headers # The HTTP headers
response.body # The parsed response
response.raw_body # The unparsed response

異步請求

Python也支持異步請求，可以在其中定義一個回調函數，以及傳遞和調用時Unirest接收響應：

def callback_function(response):
  response.code # The HTTP status code
  response.headers # The HTTP headers
  response.body # The parsed response
  response.raw_body # The unparsed response

thread = unirest.post("http://httpbin.org/post", headers={ "Accept": "application/json" }, params={ "parameter": 23, "foo": "bar" }, callback=callback_function)

文件上傳

傳輸文件數據，您需要以可讀r模式打開文件：

response = unirest.post("http://httpbin.org/post", headers={"Accept": "application/json"},
  params={
    "parameter": "value",
    "file": open("/tmp/file", mode="r")
  }
)

自定義Entity Body

import json

response = unirest.post("http://httpbin.org/post", headers={ "Accept": "application/json" },
  params=json.dumps({
    "parameter": "value",
    "foo": "bar"
  })
)

Note: For the sake of semplicity, even with custom entities in the body, the keyword argument is still params (instead of data for example). I'm looking for feedback on this.

基本的身份驗證

Authenticating the request with basic authentication can be done by providing an auth array like:

response = unirest.get("http://httpbin.org/get", auth=('username', 'password'))

請求

unirest.get(url, headers = {}, params = {}, auth = (), callback = None)
unirest.post(url, headers = {}, params = {}, auth = (), callback = None)
unirest.put(url, headers = {}, params = {}, auth = (), callback = None)
unirest.patch(url, headers = {}, params = {}, auth = (), callback = None)    
unirest.delete(url, headers = {}, params = {}, auth = (), callback = None)

• url - Endpoint, address, or URI to be acted upon and requested information from in a string format.
• headers - Request Headers as an associative array
• params - Request Body as an associative array or object
• auth - The Basic Authentication credentials as an array
• callback - Asychronous callback method to be invoked upon result.
