python - 读取json、解析成data、json.dumps(data)后json无效

Question

考虑python中的以下代码：

    import requests
    import json
    url = 'https://api.pushshift.io/reddit/submission/search?ids=d1de8g'
    raw_data = requests.get(url)
    data = raw_data.json()['data'][0]
    js = json.dumps(data)

js不返回有效的 json。
（这个json可以在这里看到）

任何 web 解析器都会报告 key 的问题selftext。
Elasticsearch 不会接受这个 json。
也就是说，json.loads(js)工作正常并返回正确的对象。

我怀疑问题在于 json.dumps 转义引号，例如在C\'est. 但我不确定如何处理。
理想情况下，我想尽可能多地限制data.

我无法重现您的问题。我刚刚在您的代码末尾添加了这个：

with open('temp.json', 'w') as f:
    f.write(js)

我打开该文件并使用在线 json lint 对其进行测试，它是完全有效的。

这是完整的文件内容：

我可以看到你的粘贴有双重转义，我不知道为什么。也许这与您如何打印变量的内容有关。
