python筆記8：requests模組-Python教學-PHP中文網

簡介：

requests是python的一個http客戶端函式庫，跟urlib、urlib2類似，requests模組是基於urlib模組開發的，程式碼實作更為簡潔。

模組安裝：

pip install requests ，使用requests模組時直接import requests即可。

簡單使用requests：

http協定的接口，請求方式分為get和post，這2種最為常用。請求參數常用的形式有key-value、json、檔案上傳、介面新增cookies、headers等操作。

get請求-url拼接參數：

<span style="color: #0000ff">import</span><span style="color: #000000"> requests
url </span>= <span style="color: #800000">'</span><span style="color: #800000">http://127.0.0.1:5000/gettest?username=abc</span><span style="color: #800000">'</span>
<span style="color: #008000">#</span><span style="color: #008000">返回结果类型是字符串：{"msg": "pass"}</span>
res =<span style="color: #000000"> requests.<span style="color: #ff0000">get</span>(url).text</span><span style="color: #0000ff"><br></span>

也可以使用.json(),傳回結果型別是字典 (註:介面請求的回傳值型別與介面的回傳定義型別有關)
