这就是我在做的事。

我正在向reddit oembed端点发送get请求。我想解析返回的json并获取原始的html，将reddit文章嵌入到django页面上。当我尝试这样做时，我收到的错误是

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

下面是该代码的一个实际操作示例。(它在一个函数中)

 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']

这是它应该返回的html。，我在想，也许我必须重新格式化它？能帮我一下吗？谢谢!

 '\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'

编辑：

以下是打印endpoint.json()的结果

    {
   "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",
   "author_name":"tanookiben"
}

我没有发一个合适的头球。一直得到一个429错误，因为没有返回json，所以我收到了json解码器错误。

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，它看起来像下面这样的reddit响应错误消息。因此，最好先检查响应状态代码。

<!doctype html>
<html>
  <head>
    <title>Too Many Requests</title>
    <style>
      body {
          font: small verdana, arial, helvetica, sans-serif;
          width: 600px;
          margin: 0 auto;
      }

      h1 {
          height: 40px;
          background: transparent url(//www.redditstatic.com/reddit.com.header.png) no-repeat scroll top right;
      }
    </style>
  </head>
  <body>
    <h1>whoa there, pardner!</h1>
