怎么在Python中利用Cookies导出用户数据？很多新手对此不是很清楚，为了帮助大家解决这个难题，下面小编将为大家详细讲解，有这方面需求的人可以来学习下，希望你能有所收获。
利用抓包工具或者Google浏览器调试模式拿到请求参数
Cookies参数如下：
cookies = { 'JSESSIONID': 'XXX', 'phone': 'XXX', 'password': 'XXX', 'isAuto': '0', ' loginAccess': 'XXX'}headers请求头信息构造：
headers = { 'Connection': 'keep-alive', 'sec-ch-ua': '"Google Chrome";v="89", "Chromium";v="89", ";Not A Brand";v="99"', 'Accept': 'application/json, text/javascript, */*; q=0.01', 'X-Requested-With': 'XMLHttpRequest', 'sec-ch-ua-mobile': '?0', 'User-Agent': 'Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/89.0.4389.90 Safari/537.36', 'Content-Type': 'application/json', 'Sec-Fetch-Site': 'same-origin', 'Sec-Fetch-Mode': 'cors', 'Sec-Fetch-Dest': 'empty', 'Referer': 'https://xxx.xxx.xxx', 'Accept-Language': 'zh-CN,zh;q=0.9',}请求路径：
params = ( ('method', 'getGoodsList'))请求参数组装：
data = '{"pageSize":1000,"pageNumber":1,"searchText":"","sortOrder":"asc","isAdvancedSearch":false}'pageSize：每页数据数量
pageNumber：页码
searchText：搜索条件
sortOrder：排序
3.利用Requests模拟请求并获取数据
response = requests.post( 'https://xxx.xxx.xxx', headers=headers, params=params, cookies=cookies, data=data)print(response.text.encode('utf8'))res = json.loads(response.text)4.创建Excel表格
t = time.time()randStr = int(round(t * 1000))tSheetName = "a_" + str(randStr) + ".xlsx"workbook = xlsxwriter.Workbook(tSheetName)worksheet = workbook.add_worksheet()5.表头及数据组装
cursor = 0picurl = ''writeExcel(row=cursor)for obj in res["rows"]: cursor += 1 picurl = '' if obj['ImageKID']: picurl = 'https://xxx.xxx.xxx? imageKid='+obj['ImageKID'] writeExcel(row=cursor,Description=obj['Description'], Category=obj['Category'], Series=obj['Series'],BaseUnit=obj['BaseUnit'],Qty=obj['Qty'], CostPrice=obj['CostPrice'],SalePrice=obj['SalePrice'], RetailPrice=obj['RetailPrice'],Barcode=obj['Barcode'], Remark=obj['Remark'], ImageKID=picurl)6.将数据写入Excel表格中
def writeExcel(row=0, Description='', Category='', Series='', BaseUnit='', Qty='', CostPrice='', SalePrice='', RetailPrice='', Barcode='', Remark='',ImageKID=''): if row == 0: worksheet.write(row, 0, '名称') worksheet.write(row, 1, '货号') worksheet.write(row, 2, '规格') worksheet.write(row, 3, '单位') worksheet.write(row, 4, '库存') worksheet.write(row, 5, '成本') worksheet.write(row, 6, '批发价') worksheet.write(row, 7, '零售价') worksheet.write(row, 8, '条码') worksheet.write(row, 9, '备注') worksheet.write(row, 10, '图片') else: if ImageKID!='': image_data = io.BytesIO(urllib.urlopen(ImageKID).read()) worksheet.insert_image(row, 10, ImageKID, {'image_data': image_data}) worksheet.write(row, 0, Description) worksheet.write(row, 1, Category) worksheet.write(row, 2, Series) worksheet.write(row, 3, BaseUnit) worksheet.write(row, 4, Qty) worksheet.write(row, 5, CostPrice) worksheet.write(row, 6, SalePrice) worksheet.write(row, 7, RetailPrice) worksheet.write(row, 8, Barcode) worksheet.write(row, 9, Remark) worksheet.set_column(10, 10, 23) worksheet.set_row(row, 150)注意图片路径不存在的情况，否则会执行异常
write方法：
def write(self, row, col, *args): """ Write data to a worksheet cell by calling the appropriate write_*() method based on the type of data being passed. Args: row: The cell row (zero indexed). col: The cell column (zero indexed). *args: Args to pass to sub functions. Returns: 0: Success. -1: Row or column is out of worksheet bounds. other: Return value of called method. """ return self._write(row, col, *args)通过set_row方法设置表格行高
def set_row(self, row, height=None, cell_format=None, options=None): """ Set the width, and other properties of a row. Args: row: Row number (zero-indexed). height: Row height. (optional). cell_format: Row cell_format. (optional). options: Dict of options such as hidden, level and collapsed. Returns: 0: Success. -1: Row number is out of worksheet bounds....... """通过set_column方法设置图片列宽度：
def set_column(self, first_col, last_col, width=None, cell_format=None, options=None): """ Set the width, and other properties of a single column or a range of columns. Args: first_col: First column (zero-indexed). last_col: Last column (zero-indexed). Can be same as first_col. width: Column width. (optional). cell_format: Column cell_format.

""" # Check insert (row, col) without storing. if self._check_dimensions(row, col, True, True): warn('Cannot insert image at (%d, %d).' % (row, col)) return -1 if options is None: options = {} x_offset = options.get('x_offset', 0) y_offset = options.get('y_offset', 0) x_scale = options.get('x_scale', 1) y_scale = options.get('y_scale', 1) url = options.get('url', None) tip = options.get('tip', None) anchor = options.get('object_position', 2) image_data = options.get('image_data', None) description = options.get('description', None) decorative = options.get('decorative', False) # For backward compatibility with older parameter name. anchor = options.get('positioning', anchor) if not image_data and not os.path.exists(filename): warn("Image file '%s' not found." % force_unicode(filename)) return -1 self.images.append([row, col, filename, x_offset, y_offset, x_scale, y_scale, url, tip, anchor, image_data, description, decorative]) return 0注意insert_image(row, colunmNum, ‘xx.png', {‘url': xxx}）并不能插入网络图片，只是给本地图片一个url路径
7.关闭表格
workbook.close()8.附引入的包
# -*- coding: UTF-8 -*-# 批量获取XX数据import ioimport json import requestsimport sysimport xlsxwriterimport timeimport urllib9.代码跑起来
