这个错误提示意味着你在尝试读取一个值的属性,但是这个值是null,也就是空的。在这个特定的例子中,错误是"TypeError: Cannot read properties of null (reading 'content')"。根据引用中的例子,可能是因为你尝试读取一个叫做'content'的属性,但是该属性所在的对象是null,所以导致了这个错误。解决这个问题的方法是在读取属性之前,先判断该属性所在的对象是否为null。你可以使用条件语句,比如if语句来进行判断,如果对象不为null,再去读取属性。这样可以避免出现这个错误。<span class="em">1</span><span class="em">2</span><span class="em">3</span>
