我发现在大多数情况下，当字符串出现问题时会出现这种类型的错误，但是我检查了字符串，而字符23630（在vim中）只显示了一个普通字符。所以我不知道字符串有什么问题。我找到了this one这样的帖子，但它们并没有真正帮助。
答案 0 :(得分：3)
您的JSON无效。您可以尝试this非常有用的资源，它可以向您显示JSON文件中的错误。使用＆＃34;验证JSON＆＃34; ，找到错误应该没有问题。只需复制/粘贴两个"""之间的JSON即可。
答案 1 :(得分：1)
最后有一个糟糕的结束括号：
...f-title":{"ref-titletext":{"sup":"*"}]}}}}}}"""
