为什么我会收到此 JSON 解码错误？

Question

这是我正在做的事情。

我正在向 reddit oembed 端点发送获取请求。我想解析 returned json 并获取原始 html 以将 reddit post 嵌入到我的 django 页面上。我尝试执行此操作时收到的错误是

json.decoder.JSONDecodeError: Expecting value: line 2 column 1 (char 1)

下面是该代码的一个示例。（它在函数内部）

 endpoint = requests.get("https://www.reddit.com/oembed?url=https://www.reddit.com/r/nba/comments/n6l2zu/the_crew_lock_in_their_predictions_and_ernie_has/")

 return endpoint.json()['html']

这里是 html 它应该 return。 我在想也许我必须重新格式化它？有人可以帮我吗？谢谢！

编辑：

这是打印的结果 endpoint.json()

    {
   "provider_url":"https://www.reddit.com/",
   "version":"1.0",
   "title":"The crew lock in their predictions and Ernie has the Jazz going to the Finals",
   "provider_name":"reddit",
   "type":"rich",
   "html":"\n    <blockquote class=\"reddit-card\" >\n      <a href=\"https://www.reddit.com/r/nba/comments/n6l2zu/the_crew_lock_in_their_predictions_and_ernie_has/?ref_source=embed&amp;ref=share\">The crew lock in their predictions and Ernie has the Jazz going to the Finals</a> from\n      <a href=\"https://www.reddit.com/r/nba/\">nba</a>\n    </blockquote>\n    <script async src=\"https://embed.redditmedia.com/widgets/platform.js\" charset=\"UTF-8\"></script>\n",

import requests
import json

def get_response():
    endpoint = requests.get("https://www.reddit.com/oembed?url=https://www.reddit.com/r/nba/comments/n6l2zu/the_crew_lock_in_their_predictions_and_ernie_has/")
    if endpoint.status_code == 200:
        return json.loads(endpoint.text)
        
    return {}
    
print(get_response())

当您发出请求时，reddit 似乎会响应如下错误消息。所以最好先检查响应状态码。

<!doctype html>

      }

我没有发送正确的 header。一直返回 429 错误，因为没有返回 json，我收到 json 解码器错误。

为什么我会收到此 JSON 解码错误？
