响应显示<200>，但IEEE中没有内容

Question

我正在学习有关网络爬网的知识，我想对IEEE中的所有期刊进行爬网，但是搜索应该是输入关键字

最后，我在此网址中找到了“高级搜索”

  

https://ieeexplore.ieee.org/search/advsearch.jsp?expression-builder

并输入以下命令，我们可以获取期刊论文

  

“出版物标题”：期刊

现在我输入一些要爬网的代码，响应显示<200>，但其中没有任何内容

请求网址是

request_url = 'https://ieeexplore.ieee.org/rest/search'

标题是

headers = {
    'Content-Type': 'application/json',    # here if i don't add this term, the response will show 403
    # and I also change the user-agent like the online teaching, 
      but it's still nothing 
}

有效负载与“请求有效负载”中显示的有效负载

payload = {
            "action":"search",
            "matchBoolean":True,
            "searchField":"Search_All",
            "queryText":"(\"Publication Title\":journal)",
            "newsearch":True,
            "highlight":True,
            "returnFacets":["ALL"],
            "returnType":"SEARCH"
           }

最后我们要求

res = requests.post(url= request_url, data=payload, headers = headers) # response<200>

test = res.text # here the content is empty ?
# here the test result = ''

反正有解决这个问题的方法吗？
