python3 Mock開發

直接舉例

請求報文：

以上mock涉及MongoDB操做、DES解密（參考以前寫的文章）、表單數據的接收及發送。其中表單接收時須要注意根據編碼類型的不一樣，處理的方式也不同：

application/x-www-form-urlencoded對應request.form

application/xml或text/xml對應request.data

application/json對應request.json

發送表單信息的時候，咱們也能夠設置編碼類型，經過Response的mimetype參數設置：

Response(json.dumps(result, ensure_ascii=False), mimetype='application/json')
