我知道有人问过这个问题,但我无法让这个问题发挥作用,这让我大吃一惊。我正在尝试使用以下代码将多个图像上传到我的服务器:
var formidable = require('formidable');
var fs = require('fs');
...
router.post('/add_images/:showcase_id', function(req, res){
if(!admin(req, res)) return;
var form = new formidable.IncomingForm(),
files = [];
form.uploadDir = global.__project_dirname+"/tmp";
form.on('file', function(field, file) {
console.log(file);
file.image_id = global.s4()+global.s4();
file.endPath = "/img/"+file.image_id+"."+file.type.replace("image/","");
files.push({field:field, file:file});
});
form.on('end', function() {
console.log('done');
console.log(files);
db.get("SOME SQL", function(err, image_number){
if(err){
console.log(err);
}
var db_index = 0;
if(image_number) db_index = image_number.image_order;
files.forEach(function(file, index){
try{
//this line opens the image in my computer (testing)
require("sys").exec("display " + file.file.path);
console.log(file.file.path);
fs.renameSync(file.file.path, file.file.endPath);
}catch (e){
console.log(e);
}
db.run( "SOME MORE SQL"')", function(err){
if(index == files.length)
res.redirect("/admin/gallery"+req.params.showcase_id);
});
});
});
});
form.parse(req);
});
通过系统调用打开图像的行工作得很好,但是我继续得到:
Error: ENOENT, no such file or directory '/home/[username]/[project name]/tmp/285ef5276581cb3b8ea950a043c6ed51'
通过 rename 语句。
file.file.path 的值是:
/home/[username]/[project name]/tmp/285ef5276581cb3b8ea950a043c6ed51
我很困惑,什么都试过了。我究竟做错了什么?
