强大的文件路径未定义
Formidable file path undefined
我在尝试重命名要上传到服务器的文件时遇到了问题,我搜索了很多,包括 ,但 none 似乎对我有用。我的代码在另一个项目中工作,所以我复制到这个但是没有成功,都有同样的错误;路径未定义
html:
<form action = "/assignment1/viewImage/upload" enctype="multipart/form-data" method="post">
<input type="text" name="title"><br />
<input type="file" name="upload" multiple="multiple"><br>
<input type = "submit" value="Upload"/>
js(路由器):
handle["/assignment1/viewImage/upload"] = reqHandlers.reqUpload;
js(reqHandler):
function reqUpload(res, path, postData, req){
var form = new formidable.IncomingForm();
form.uploadDir = './tmp';
form.parse(req, function(err, field, file) {
console.log("parsing done\n\n" + file.upload.path + "\n\n" + field);//file.upload.path and field is somehow undefined
fs.rename(file.upload.path, "../images/test.png", function (err) {
if (err) {
fs.unlink("./tmp/test.png");
fs.rename(file.upload.path, "../images/test.png");
}
});
res.writeHead(200,{"Content-Type": "text/html"});
res.write("Received image: <br/>");
res.write("<img src='/assignment1/show' />");
res.end();
});
}
控制台输出:
尝试更新版本 npm i node-formidable/formidable#3.x
然后使用options.filename
代替fs.rename
晚更新;所以我确实正确复制了它除了我错过了将部分放在服务器端(未显示)不应该将编码更改为UTF-8(应该是application/multiform),这导致文件路径无法是被程序读取
截至 2022 年 1 月,迁移问题。
function reqUpload(res, path, postData, req){
const options = {
uploadDir : './tmp'
}
const form = new formidable.IncomingForm(options);
form.parse(req, function(err, field, file) {
console.log("parsing done \n" + file.upload.filepath);
console.log(file.upload.originalFilename, " ", file.upload.newFilename);
res.end();
});
}
