代码解析
1.请求头
构造请求头
urllib3.disable_warnings(urllib3.exceptions.InsecureRequestWarning)
sys.stdout = io.TextIOWrapper(sys.stdout.buffer, encoding='utf-8')
url = "https://ip/ma/web/trade/dailySummary?startDate={pi_startdate}&android;endDate={pi_enddate}"
headers = {
"Accept": "text/html,application/xhtml+xml,application/xml;q=0.9,image/avif,image/webp,image/apng,*/*;q=0.8,applicatiphpon/signed-exchange;v=b3;q=0.7",
"Accept-Language": "zh-CN,zh;q=0.9",
"User-Agent": "Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/119.0.0.0 Safari/537.36 Edg/119.0.0.0",
}
2.数据保存到excel
如果excel已经存在，那么则会将数据追加到excel中
def save_data(data, columns, excel_path, sheet_name):
df = pd.DataFrame(data, columns=columns)
if not os.path.exists(excel_path):
df.to_excel(excel_path, sheet_name=sheet_name, index=False)
else:
with pd.ExcelWriter(excel_path, engine='openpyxl', mode='a') as writer:
df.to_excel(writer, sheet_name=sheet_name, index=False)
解析json数据获取字段名称以及对应的数据list列表
def json2list(response_text):
# 把json数据转化为python用的类型
json_dict = json.loads(response_text)
src_total = json_dict["total"]
print("src_total: {}".format(src_total))
items = json_dict["items"]
excel_columns = ['summaryDate',
'summaryType',
'workday',
'newCustNum',
'haveCustNum',
'newAccountNum',
'haveAccountNum',
'totalShare',
'netCash',
'yield'
]
excel_data = []
# 使用XPath定位元素并打印内容
for item in items:
excel_row_data = []
for column_index in range(len(excel_columns)):
data = str(item[excel_columns[column_index]])
if excel_columns[column_index] == 'workday':
data = str(0 if data == "False" else 1)
excel_row_data.append(data)
excel_data.append(excel_row_data)
trg_total = len(excel_data)
# 稽核
print("trg_total: {}".format(trg_total))
vn_biasval = trg_total - src_total
if vn_biasval != 0:
print("This audit-rule is not passed,diff: {}".format(vn_biasval))
exit(-1)
else:
print("This audit-rule is passed,diff: {}".format(vn_biasval))
return excel_columns, excel_data
3.测试方法入口
if __name__ == '__main__':
测试结果
会生成ylb_dailySummary_20240611_20240613.xlsx文件
