麻烦帮忙修改一下python代码
limit超过4500就没有办法爬取      网址https://www.sceea.cn/Information/Sunshine?id=210&nf=2023#  
[Python] 纯文本查看 复制代码import requests
import json
web_url = "https://www.sceea.cn/Information/GetSunshineList"
payload = {
    "Limit": "200000",
    "Page": "1",
    "gslbid": "210",
    "domParam": "",
    "Key": ""
}
headers = {
    "Origin": "https://www.sceea.cn",
    "Referer": "https://wwwsceeacn/Information/Sunshine?id=210&nf=2023",
    "Content-Type": "application/x-www-form-urlencoded; charset=utf-8"
}
response = requests.post(web_url, data=payload, headers=headers)
json_data = response.json()["gsb"]
print(response.text)
ar_data = []
for item in json_data:
    ar_data.append([
        item["GSXM1"],
        item["GSXM2"],
        item["GSXM3"],
        item["GSXM4"],
        item["GSXM5"],
        item["GSXM6"],
        item["GSXM7"],
        item["GSLBID"],
        item["ID"]
    ])
# 将数据写入Excel文件中的Sheet2
import openpyxl
workbook = openpyxl.Workbook()
sheet = workbook.active
for row in range(len(ar_data)):
    for col in range(len(ar_data[row])):
        sheet.cell(row=row+2, column=col+1).value = ar_data[row][col]
workbook.save("output.xlsx")

代码, 没有办法

Limit小一些，加上Page呢，Page不要一直是1

建议方案：
1. 4500是上限的话 ，就用4000，翻页查询
2. 每次请求之间加上延迟，爬太快就会出错

GPT4.0 ：从您的描述中，我了解到您遇到的问题是，当请求的数据量超过4500条时，您无法正常获取到数据。这可能是由于服务器对单次请求返回的数据量有限制。为解决这个问题，我们可以分批次请求数据，每次请求一个较小的数据量，每次请求1000条，，直到达到200000条数据或者没有更多数据为止。然后将所有获取到的数据保存到一个Excel文件中。以下是修改后的代码：

    payload = {

        "Page": page,
        "gslbid": "210",
        "domParam": "",
        "Key": ""
    }
    response = requests.post(web_url, data=payload, headers=headers)
    json_data = response.json()["gsb"]
    return json_data
def save_data_to_excel(ar_data, file_name):
    workbook = openpyxl.Workbook()
    sheet = workbook.active
    for row in range(len(ar_data)):
        for col in range(len(ar_data[row])):
            sheet.cell(row=row+2, column=col+1).value = ar_data[row][col]
    workbook.save(file_name)
limit_per_request = 1000
total_data_limit = 200000
ar_data = []
page = 1
while len(ar_data)

不要一次性获取大量数据，可以按照限制值小一点设置，再增加延迟时间，根据总数量分词读取保存即可。
