node.js - Node JS 错误 : ENOENT

标签 node.js

我正在关注: The Node Beginner Book

使用另一篇 SO 帖子中的代码进行测试后:

var Fs = require('fs');

var dirs = ['tmp'];
var index;
var stats;

for (index = 0; index < dirs.length; ++index)
{
    try
    {
        stats = Fs.lstatSync(dirs[index]);
        console.log(dirs[index] + ": is a directory? " + stats.isDirectory());
    }
    catch (e)
    {
        console.log(dirs[index] + ": " + e);
    }
}

错误仍然存​​在:

Error: ENOENT, no such file or directory 'tmp'

app dir structure

tmp 的权限为 777。

requestHandlers.js

var querystring = require("querystring"),
    fs = require("fs");

function start(response, postData) {
  console.log("Request handler 'start' was called.");

  var body = '<html>'+
    '<head>'+
    '<meta http-equiv="Content-Type" '+
    'content="text/html; charset=UTF-8" />'+
    '<style>input{display: block; margin: 1em 0;}</style>'+
    '</head>'+
    '<body>'+
    '<form action="/upload" method="post">'+
    '<textarea name="text" rows="20" cols="60"></textarea>'+
    '<input type="submit" value="Submit text" />'+
    '</form>'+
    '</body>'+
    '</html>';

    response.writeHead(200, {"Content-Type": "text/html"});
    response.write(body);
    response.end();
}

function upload(response, postData) {
  console.log("Request handler 'upload' was called.");
  response.writeHead(200, {"Content-Type": "text/plain"});
  response.write("You've sent the text: "+
  querystring.parse(postData).text);
  response.end();
}

function show(response, postData) {
  console.log("Request handler 'show' was called.");
  fs.readFile("/tmp/test.jpg", "binary", function(error, file) {
    if(error) {
      response.writeHead(500, {"Content-Type": "text/plain"});
      response.write(error + "\n");
      response.end();
    } else {
      response.writeHead(200, {"Content-Type": "image/jpg"});
      response.write(file, "binary");
      response.end();
    }
  });
}

exports.start = start;
exports.upload = upload;
exports.show = show;

Index.js

var server = require("./server");
var router = require("./router");
var requestHandlers = require("./requestHandlers");

var handle = {}
handle["/"] = requestHandlers.start;
handle["/start"] = requestHandlers.start;
handle["/upload"] = requestHandlers.upload;
handle["/show"] = requestHandlers.show;

server.start(router.route, handle);

有点难过,感谢任何帮助。

最佳答案

"/tmp/test.jpg" 不是正确的路径 - 此路径以 / 开头,即根目录。

在unix中,当前目录的快捷方式是.

试试这个"./tmp/test.jpg"
