Python 通过请求更改 Instagram 个人资料图片

我正在尝试使用 python post 请求更改我的 Instagram 个人资料图片，但它没有改变。我没有收到任何错误，在回复中，它说他们已经更改了它，但是更改为白色 Instagram 人物照片，而不是我选择的照片。

My code:
s.headers.update(headers_above)
img_payload = {
              "file": ("blo.jpg", open("D:\\{path_to_jpg_file}", "rb"), "image/jpeg")
                    }
img_url = "https://www.instagram.com/accounts/web_change_profile_picture/"
 r3 = s.post(img_url, files=img_payload)

1. 通过firefox开发者工具嗅探上传过程后，我复制了 一切request headers to the headersof post request，但它不起作用，然后我删除了Content-Type": "multipart/form-data; boundary=-...XXXXX"繁荣！
2. 我还更新了"Content-Length"价值与os.path.getsize("my_new_pp.jpg")
3. Make sure you refresh the profile pic page with no cache, on FF, hold down the Shift key and left-click the Reload button.

我设法使用以下代码更改了 Instagram 上的个人资料图片：

import os
import requests

p_pic = "my_new_pp.jpg"
p_pic_s = os.path.getsize("my_new_pp.jpg")

headers = {
"Host": "www.instagram.com",
"User-Agent": "Mozilla/5.0 (Windows NT 10.0; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/62.0.3202.9 Safari/537.36",

"X-CSRFToken": "YOUR_X-CSRFToken",
"X-Instagram-AJAX": "YOUR_X-Instagram-AJAX",
"X-Requested-With": "XMLHttpRequest",
"Content-Length": str(p_pic_s), # should also work without this
"DNT": "1",
"Connection": "keep-alive",
"Cookie": "YOUR_COOKIE"
}

url = "https://www.instagram.com/accounts/web_change_profile_picture/"

files = {'profile_pic': open(p_pic,'rb')}
values = {"Content-Disposition": "form-data", "name": "profile_pic", "filename":"profilepic.jpg",
"Content-Type": "image/jpeg"}

r = requests.post(url, files=files, data=values, headers=headers)
print(r.text)

回复：
