问题是当我通过jQuery在javascript中调用/ getUserPath时，它返回404错误，说/ getUserPath不存在，这没有任何意义，因为一切都暴露出来了转到实际网址
www.serverurlhere.com/getUserPath?website = http://otherurlhere.com/
显示有效负载返回且有效负载有效且正确。 Javascript是100％正确的，因为我在工作之间和不是这个文件之间的唯一文件。为什么404会出现？这对我没有任何意义，因为我所做的就是为这个文件添加一个方法并且它破坏了（交换方法）。该网站显示，其他一切工作，但/ getUserPath部分刚刚破解。 cherrypy服务器中的方法数量是否有限制？对于樱桃而言，我非常无知，而且很可能是对樱桃的限制。我用Google搜索，无法找到这样的其他内容......我只是不明白这里会发生什么......
谢谢，

答案 0 :(得分：0)
这个问题的答案是使用从javascript发送的查询字符串参数为方法签名设置相同的参数名称。 CherryPy关心参数名称和接收的参数。
来自对问题的评论。
我明白了！谢谢你的帮助！事实证明这是一个非常愚蠢的错误。一切都运行正常，但我将名称为“input”的变量传递给getUserPath的名称改为名称为“website”，当POST请求发生时，当它收到除了确切变量名之外的其他内容时，它会变成404。 / p>
