Question

我正在尝试使用Python POST请求以检索特定文件。由于该网址位于具有授权访问权限的服务器后面，因此无法在此处发布网址

但是表单数据包含一个名为base64的字段，该字段很长，我无法弄清它是否是表单数据值或发布请求的base64编码

以下是浏览器参数

Form Data:
fileName: location-downloads.xlsx
contentType: application/vnd.openxmlformats-officedocument.spreadsheetml.sheet
base64: UEsDBAoAAAAAAAh4904AAAAAAAAAAAAAAAAJAAAAZG9jUHJvcHMvUEsDBAoAAAAIAAh490(shortened for simplicity)

Here is what I tried

url='http://example.com'
urllib3.disable_warnings()

headers = {
                    "Content-Type": "application/x-www-form-urlencoded",
                    "User-Agent": "Mozilla/5.0",
                }
with requests.session() as s:
    r=s.get(url,headers={"User-Agent":"Mozilla/5.0"},verify=False)
    data=r.content

    soup=BeautifulSoup(data,'html.parser')
    form_data = {
    "fileName":"location-downloads.xlsx",
    "contentType":"application/vnd.openxmlformats-officedocument.spreadsheetml.sheet"
         }
    r2=s.post('http://exampleapi.com/api/Document/Export',data=json.dumps(form_data,ensure_ascii=True).encode('utf-8'),headers=headers,verify=False)
    print(r2.status_code)

任何想法我应该如何进行。我的状态代码还显示了500个帖子
