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
在看下Excel表格中导出的信息
