我试图将文件路径存储在一个变量中，然后将它提供给 readFileSync() 函数，但这给了我在控制台中的错误。
Error: EISDIR, illegal operation on a directory
at Object.fs.readSync (fs.js:487:19)
at Object.fs.readFileSync (fs.js:326:28)
at route (D:\nodejs\file_upload\router.js:7:15)

at Server.emit (events.js:98:17)

但如果我直接在函数中输入路径“D:/nodejs/file_upload/view/index.html”，那么它会在浏览器中显示页面。
我将 index.html 文件存储在 View 文件夹中
最佳答案
EISDIR 尝试打开文件时发生错误，但给出的路径是目录。查看相关问答:Using Node.js I get, "Error: EISDIR, read" .
为了调试这个，我会登录到控制台变量 directpath 并且我会假设它指向一个目录，而不是一个文件。将此变量正确设置为预期路径应该可以解决您的问题。
