(1) form數(shù)據(jù)是可遍歷的字典,可使用字典屬性;
(2) json數(shù)據(jù)為字典,可使用字典屬性;
(3) files數(shù)據(jù)為可遍歷的字典,可使用字典屬性,通過key判斷是否存在該key,如input這個鍵;
(4) 當使用數(shù)據(jù)中的一種格式時,其他的數(shù)據(jù)為None,不可遍歷,因此直接使用if判斷是否為該類型的數(shù)據(jù),會拋出錯誤TypeError: argument of type 'NoneType' is not iterable,所以通過先判斷數(shù)據(jù)是否為空,然后判斷是否為指定格式,解除錯誤;

(1) 數(shù)據(jù)獲取使用request請求,常用數(shù)據(jù)格式有json,form,file及地址欄的get請求數(shù)據(jù);
(2) form及json數(shù)據(jù)請求方式均有兩種,如request.json.get(),request.json[];
(3) 獲取文件數(shù)據(jù),可通過filename屬性獲取文件名,save屬性進行保存;
(4) 地址欄可直接寫入數(shù)據(jù),需在route的方法內(nèi)使用格式為:<type:args>如<int:id>,<string:name>等;
(5) 通過判斷輸入數(shù)據(jù)的格式,提供不同類型的輸入;
