Title: python爬虫爬取APP并封装成API接口调用，使用flask-restful_app爬虫需要接囗吗?-CSDN博客

#环境python3.6

\# 爬取APP 无忧借条

\# 通过用户账号密码爬取用户个人信息（我这账号密码已打码）

爬虫部分代码

import hashlibimport timeimport urllib3import jsonheaders = {'Accept': ' */*', 'Accept-Encoding': 'gzip, deflate', 'Accept-Language': 'zh-CN,en-US;q=0.8','User-Agent': 'Mozilla/5.0 (Linux; Android 6.0.1; Redmi 3S Build/MMB29M; wv) AppleWebKit/537.36 (KHTML, like Gecko) Version/4.0 Chrome/53.0.2785.49 Mobile MQQBrowser/6.2 TBS/043632 Safari/537.36 jinjiedao'}origin_data = {} result={} http = urllib3.PoolManager() urllib3.disable_warnings() def login(phone,password): login_url='https://www.gushistory.com/jjdApi/user/login' headers['refer'] = 'https://www.gushistory.com/jjdapp/html/register/login.html?telephone=' + phone md5 = hashlib.md5() md52 = hashlib.md5() md5.update(password.encode(encoding='utf-8')) md52.update(md5.hexdigest().encode(encoding='utf-8')) data={'c_telephone': phone, 'c_pwd': md52.hexdigest()} response=excute(login_url,'GET',data) origin_data['login'] = responsereturn response['token']def getAccountInfo(token): account_url='https://www.gushistory.com/jjdApi/user/getHomepageInfo' headers['refer'] = 'https://www.gushistory.com/jjdapp/html/index.html' data = {'token': token} response = excute(account_url, 'GET', data) origin_data['account'] = response user_info = response['userInfo'] result['balance'] = user_info['n_left_amt'] result['wait_repay_amt'] = user_info['n_to_repay_amt'] result['wait_receive'] = user_info['n_to_receive_amt'] result['lender_cnt'] = response['borrowInfo']['n_lender_cnt'] result['phone'] = user_info['c_telephone'] if 'c_name' in user_info: result['name'] = user_info['c_name']else: result['name'] = '未实名'if 'c_id_card_no' in user_info: result['id_card'] = user_info['c_id_card_no']return resultdef excute(url, method, data):if data == None: data = {} data['timestamp'] = int(round(time.time() * 1000)) r = http.request(url=url, method=method, headers=headers, fields=data) response = json.loads(r.data.decode('utf-8'))if response['code'] == 200:return response['object']else: response['error'] = '处理失败'return responseif __name__=="__main__": phone='1516842****' pwd='123456' token = login(phone, pwd) getAccountInfo(token)

运行完结果为json数据


以上是爬虫部分，接下来先把API接口模板写好：

from flask import Flask, gfrom flask_restful import reqparse, Api, Resourcefrom flask_httpauth import HTTPTokenAuthapp = Flask(__name__)api = Api(app)parser_put = reqparse.RequestParser()parser_put.add_argument("user", type=str, required=True, help="need user data")parser_put.add_argument("pwd", type=str, required=True, help="need pwd data")

def to_do(arg1, args2):return "this is info"class TodoList(Resource):def post(self):""" 添加一个新用户: curl http://127.0.0.1:5000/users -X POST -d "name=Brown&age=20" -H "Authorization: token fejiasdfhu" """ args = parser_put.parse_args() user = args['user'] pwd = args['pwd'] info = {"info": to_do(user, pwd)}return info, 201api.add_resource(TodoList, "/users")if __name__ == "__main__": app.run(debug=True)

接下来将爬虫部分镶嵌到到模板里面，完整代码如下：

from flask import Flask, gfrom flask_restful import reqparse, Api, Resourcefrom flask_httpauth import HTTPTokenAuthimport hashlibimport timeimport urllib3import jsonapp = Flask(__name__)api = Api(app)parser_put = reqparse.RequestParser()parser_put.add_argument("user", type=str, required=True, help="need user data")parser_put.add_argument("pwd", type=str, required=True, help="need pwd data")headers = {'Accept': ' */*', 'Accept-Encoding': 'gzip, deflate', 'Accept-Language': 'zh-CN,en-US;q=0.8','User-Agent': 'Mozilla/5.0 (Linux; Android 6.0.1; Redmi 3S Build/MMB29M; wv) AppleWebKit/537.36 (KHTML, like Gecko) Version/4.0 Chrome/53.0.2785.49 Mobile MQQBrowser/6.2 TBS/043632 Safari/537.36 jinjiedao'}origin_data = {} result = {} http = urllib3.PoolManager() urllib3.disable_warnings() def login(phone, password): login_url = 'https://www.gushistory.com/jjdApi/user/login' headers['refer'] = 'https://www.gushistory.com/jjdapp/html/register/login.html?telephone=' + phone md5 = hashlib.md5() md52 = hashlib.md5() md5.update(password.encode(encoding='utf-8')) md52.update(md5.hexdigest().encode(encoding='utf-8')) data = {'c_telephone': phone, 'c_pwd': md52.hexdigest()} response = excute(login_url, 'GET', data) origin_data['login'] = responsereturn response['token']def getAccountInfo(token): account_url = 'https://www.gushistory.com/jjdApi/user/getHomepageInfo' headers['refer'] = 'https://www.gushistory.com/jjdapp/html/index.html' data = {'token': token} response = excute(account_url, 'GET', data) origin_data['account'] = response user_info = response['userInfo'] result['balance'] = user_info['n_left_amt'] result['wait_repay_amt'] = user_info['n_to_repay_amt'] result['wait_receive'] = user_info['n_to_receive_amt'] result['lender_cnt'] = response['borrowInfo']['n_lender_cnt'] result['phone'] = user_info['c_telephone'] if 'c_name' in user_info: result['name'] = user_info['c_name']else: result['name'] = '未实名'if 'c_id_card_no' in user_info: result['id_card'] = user_info['c_id_card_no']return resultdef excute(url, method, data):if data == None: data = {} data['timestamp'] = int(round(time.time() * 1000)) r = http.request(url=url, method=method, headers=headers, fields=data) response = json.loads(r.data.decode('utf-8'))if response['code'] == 200:return response['object']else: response['error'] = '处理失败'return responsedef to_do(phone, password): token = login(phone, password)return getAccountInfo(token)class TodoList(Resource):def post(self):""" 添加一个新用户: curl http://127.0.0.1:5000/users -X POST -d "name=Brown&age=20" -H "Authorization: token fejiasdfhu" """ args = parser_put.parse_args() user = args['user'] pwd = args['pwd'] info = {"info": to_do(user, pwd)}return info, 201api.add_resource(TodoList, "/users")if __name__ == "__main__": app.run(debug=True)

这是用postman测试工具模拟浏览器请求，得出的结果
