python爬虫时Status code是500怎么解

import requests
import json

IEEE_response = requests.post(url=url, data=json.dumps(data),headers=headers, verify=False)
print(IEEE_response.status_code)
response_text = IEEE_response.text

爬取ie xplore的论文时,返回的status_code是500,添加了全部请/求头的信息和参数结果还是一样

    在传递json格式数据时(content-type: application/json),使用json参数

    import requests
    
    headers = {
        "Content-Type": "application/json",
        "Host": "ieeexplore.ieee.org",
        "Origin": "https://ieeexplore.ieee.org",
        "User-Agent": "Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/91.0.4472.164 Safari/537.36"
    }
    
    data = {
        "highlight": "true",
        "matchPubs": "true",
        "pageNumber": "3",
        "queryText": "image processing",
        "ranges": ["2010_2021_Year"],           ## 注意这里是数组,而不是字符串
        "refinements": ["ContentType:Standards"],
        "returnFacets": ["ALL"],
        "returnType": "SEARCH"
    }
    
    url = 'https://ieeexplore.ieee.org/rest/search'
    IEEE_response = requests.post(url=url, json=data, headers=headers)
    print(IEEE_response.text)
