相关文章

我的问题和这篇文章很相似，用了同样的方法解决

知乎一篇有关原理的文章

具体问题解说

富文本只是上传文字，能正常修改和保存。
不加图片时候截图
但是加上图片就报上面的错。加上图片后的，注意看绑定的字符串，问题就出在 // 上。后端在解析字符串的时候报错了。
加图片后的截图

我的解决方案：

在配置文件中截图对应位置，配置上防止xss攻击的设置。把enabled设置为true，再在后面写上报错的请求路径就行了。
解决问题具体截图
当然这并不是最优的解决方法，如果有更优的解决方法欢迎留言赐教。
也有的文章说把字符串转一下，请求数据的时候再转回来，我觉得有些麻烦，就没有用这种方法。
