应朋友需要，想将某客户的数据从某站里导出，先去某站搞个账号，建几条数据观察一番，心里有底后开搞。
1.Python环境搭建
之前电脑有安装过PyCharm Community 2019.1，具体安装过程就不写了，先跑个HelloWorld，输出正常后正式开整。
2.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 = 0
picurl = ''
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. (optional).
options: Dict of options such as hidden and level.
Returns:
0: Success.
-1: Column number is out of worksheet bounds.
......
"""
通过insert_image插入网络图片：
def insert_image(self, row, col, filename, options=None):
"""
Insert an image with its top-left corner in a worksheet cell.
Args:
row: The cell row (zero indexed).
col: The cell column (zero indexed).
filename: Path and filename for image in PNG, JPG or BMP format.
options: Position, scale, url and data stream of the image.
Returns:
0: Success.
-1: Row or column is out of worksheet bounds.
"""
# 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 io
import json
import requests
import sys
import xlsxwriter
import time
import urllib
9.代码跑起来
