获取网页返回的响应，这是一个嵌套的json数据；
定位到 "data"键下"title"键对应的值，这是PDF文件的标题；
定位到 "data"键下 "attachPath"键对应的值，这是PDF文件URL，前面加上"https://disc.static.szse.cn"，构成一个完整的PDF下载URL；
下载PDF文件，保存到文件夹：F:\AI自媒体内容\AI炒股\REITs
注意：每一步都要输出信息
PDF文件标题中可能包括一些不符合window系统命名规则的特殊符号，在重命名PDF文件前要先进行处理；
每下一个PDF文件，就随机暂停3-6秒；

定义请求载荷
payload = {
"seDate": ["", ""],
"channelCode": ["reits-xxpl"],
"bigCategoryId": ["directions"],
"pageSize": 50,
"pageNum": 1
}
发送POST请求
response = requests.post(url, headers=headers, json=payload)
检查响应状态码
if response.status_code == 200:
print("请求成功，状态码: 200 OK")
else:
print(f"请求失败，状态码: {response.status_code}")
exit()
解析JSON响应
data = response.json()
检查是否有数据
if "data" in data and isinstance(data["data"], list):
for item in data["data"]:
获取PDF标题
pdf_title = item.get("title", "unknown_title")
print(f"PDF标题: {pdf_title}")
获取PDF URL
pdf_url = item.get("attachPath", "")
if pdf_url:
pdf_url = "https://disc.static.szse.cn" + pdf_url
print(f"PDF URL: {pdf_url}")
