推荐答案

来自HTTP规范:

10.4.5 404未找到

服务器未找到任何内容匹配Request-URI.不指示是否条件是暂时的或永久的....此状态码通常是在服务器不希望使用时使用确切说明请求的原因被拒绝，或者没有其他人被拒绝响应是适用的.

The server has not found anything matching the Request-URI. No indication is given of whether the condition is temporary or permanent. ... This status code is commonly used when the server does not wish to reveal exactly why the request has been refused, or when no other response is applicable.

...因此服务器很可能没有(或找不到)您要的文件.

... so it's likely that the server doesn't have (or can't find) the file you're asking it for.

如果您认为该文件应该存在(即，您控制服务器并创建了文件):

If you think that the file should be there (i.e. you control the server, and you created the file):

• 您在URL中指定的路径错误
• 您的URL重新映射代码可能无法正常工作
• 可能有一些配置选项阻止服务器查找文件.
