一键评教，查询成绩，批量免验证码选课，退课，-云大urp教务系统大作战（3）...
这一小节没有什么好讲的，如果你学会了上一小节的中心思想：
从真实世界看程序世界
那么我们可以触类旁通的继续通过f12控制台对于真实的查询成绩，加课，退课，教学评估的流程进行模拟。
此处注意几个点：
- 注意方法的输入与输出
- 批量加课通过一个list的for循环实现
- 一键教学评估通过for循环实现。
the method to get grade（查询成绩）
#传入token值返回成绩的json
def getGrade(token):URL = 'http://202.203.209.96/v5api/api/Result/'headers={'User-Agent':'Mozilla/5.0 (iPhone; CPU iPhone OS 9_1 like Mac OS X) AppleWebKit/601.1.46 (KHTML, like Gecko) Version/9.0 Mobile/13B143 Safari/601.1','Authorization':'Bearer %s'%token}response = requests.get(URL,headers=headers)# print response.request.headersjsonobj = json.loads(response.text)print jsonobj['TeachClassList']
免验证码加课：免验证码实现及字典表请查看前几节课程
#the method to add class
def addClass(token,classCode_add):URL = 'http://202.203.209.96/v5api/api/xk/addDirect'URL2 = 'http://202.203.209.96/v5api/api/xk/Captcha'headers={'User-Agent':'Mozilla/5.0 (iPhone; CPU iPhone OS 9_1 like Mac OS X) AppleWebKit/601.1.46 (KHTML, like Gecko) Version/9.0 Mobile/13B143 Safari/601.1','Authorization':'Bearer %s'%token}fr = open('../data/dict.txt','r')dic = dict()for line in fr:line = line.strip().split(',')dic[line[0]] = line[1]fr.close()response = requests.get(URL2,headers=headers,json={'ImgGuid':'68f08ba6-8262-4726-a4ea-b1a7b346b50e'})print responseimgguid = response.text[1:-1]print imgguidcaputre = dic[imgguid]response = requests.post(URL,headers=headers,json={'id':'%s'%classCode_add,'captcha':'%s'%caputre})# print response.request.bodyprint response.status_codeprint response.text
退课remove class
def removeClass(token,classCode_remove):URL = 'http://202.203.209.96/v5api/api/xk/remove'headers={'User-Agent':'Mozilla/5.0 (iPhone; CPU iPhone OS 9_1 like Mac OS X) AppleWebKit/601.1.46 (KHTML, like Gecko) Version/9.0 Mobile/13B143 Safari/601.1','Authorization':'Bearer %s'%token}response = requests.post(URL,headers=headers,json={'id':'%s'%classCode_remove})print response.status_codeprint response.text
教学评估Teaching evaluation

此处代码有些过于重复但是为了后期每个方法的独立性而进行了冗余。后期还有改进的空间。
