django-關于JSON編碼格式的異常處理

這個是編碼格式的異常，因為在爬蟲元服務的對接中，通過http發送數據的時候，打包下來的數據封裝的格式不對

string={'domain': 'android.myapp.com', 'url': 'https://android.myapp.com/myapp/searchAjax.htm?kw=MM%E5%BA%94%E7%94%A8%E5%95%86%E5%9C%BA&pns=&sid='}

因為JSON中并沒有單引號，僅有雙引號，所以我們需要把單引號替換成雙引號了

json.decoder.JSONDecodeError: Expecting property name enclosed in double quotes

方式有多種，比如用正則

data = re.sub('\'', '\"', string.decode("utf-8"))

還可以同簡單的字符串處理

string.replace('\"', '\'')

以下是系統的異常拋出
