下面給大家看一下,fiddler抓包的結果(送出的form資訊和請求的頭部資訊):
form.PNG
請求頭:
捕獲2.PNG
接下來小編給大家解釋下form中各個參數的含義:
1 TxtBox1 &TxtBox2 後面的内容是固定不變的(我也不知道後面的值是什麼鬼)
2 ddDay 後面跟的參數是你想要預約的日期(“今日”或“明日”)
3 ddRoom 一共有7位數字(第一位表示校區,即:1----“東區”,“2”----“中區”,3----“西區”;第2-4位表示 預約教室的門牌号;後三位“001”是固定的)是以上圖中“3207001”指代的就是西區圖書館207自習室;
4 txtSeats:是已預約的座位/空閑座位
小編在撸代碼的時候,以為這個網站沒有反爬措施,是我天真了,竟然還有反爬!是以,還是老規矩需要在請求的頭部資訊加上headers,僞裝成浏覽器才行。

對了,這個網站也有驗證碼,而且還極為複雜,表示給使用者帶來了很不好的體驗,用pytesseract識别的時候,成功率幾乎為0.在下感覺這個開發者腦子裡有坑,作為一個人類的我,傾斜過後的0和o,還有g和數字9 都不厘清楚,更不要講機器了。下面是驗證碼的處理:
def get_code():
url = 'http://172.16.47.84/VerifyCode.aspx?'
resp = requests.get(url, headers=headers)
cookies['ASP.NET_SessionId'] = resp.cookies.get('ASP.NET_SessionId')
with open('code.jpg', 'wb') as img:
img.write(resp.content)
def check_show():
checkcode = Image.open("code.jpg")
image = Image.open('code.jpg')
imgry = image.convert('L')
imgry.show()
