下面是文件上传的html
<div class="form-group" >
<label for="Image">Image</label>
<input type="file" name="image" value="<%=fillData.image%>" id="inpFile" class="form-control"placeholder="drop an image " /><br>
<div class="image-preview" style="text-align: center;">
<img src="" id="imgPreview" alt="imagePreview"/>
</div>
</div>
使用
router.post("/addProduct",(req,res)=>{
const nimage = req.files.image.name
const Price = parseFloat(req.body.price).toFixed(2)
console.log(req.files.image)
const nProduct = new Products({
title:req.body.title,
slug:req.body.slug,
desc :req.body.description,
category:req.body.category,
price:Price,
image:nimage
})
nProduct.save().then((value) => {
mkdirp("public/product_images/"+nProduct._id).then(made=>{
console.log(`file created starting with on id ${made}`)
})
mkdirp("public/product_images/"+nProduct._id+"/gallery").then(made=>{
console.log(`file created starting with id and gallery ${made}`)
})
mkdirp("public/product_images/"+nProduct._id+"/gallery/thumbs").then(made=>{
console.log(`file created starting with and thumbs${made}`)
})
if(nimage!=""){
console.log("hello")
const productImage = req.files.image
const path = "public/product_images/"+nProduct._id+"/"+nimage;
console.log(path)
productImage.mv(path, function(err){
return console.log(err)
})
}
})
}
获取以下错误
[错误:eNoent:没有这样的文件或目录，打开'd:nodeepublicProduct_Images5FF718BEBE310d2F3C34590aNoImage.jpg']{errno:-4058，代码:'eNoent'，系统调用:'open'，路径:'d:nodeepublicProduct_Images5FF718BEBE310d2F3C34590aNoImage.jpg'}
您正在同步地使用mkdirp，而它是一个异步操作。
要么将所有代码移动到
router.post("/addProduct",async (req,res)=>{
const nimage = req.files.image.name
const Price = parseFloat(req.body.price).toFixed(2)
console.log(req.files.image)
const nProduct = new Products({
title:req.body.title,
slug:req.body.slug,
desc :req.body.description,
category:req.body.category,
price:Price,
image:nimage
})
await nProduct.save();
await mkdirp("public/product_images/"+nProduct._id);
await mkdirp("public/product_images/"+nProduct._id+"/gallery");
await mkdirp("public/product_images/"+nProduct._id+"/gallery/thumbs");
if(nimage!=""){
console.log("hello")
const productImage = req.files.image
const path = "public/product_images/"+nProduct._id+"/"+nimage;
console.log(path)
productImage.mv(path, function(err){
return console.log(err)
})
}
}
您需要链接 例如。 或者如果您想在创建所有目录后编写mkdirp(...)
.then(made=>{
// write to directory here
})
Promise.all(mdirp('...'), mdirp('...'), mdirp('...'))
.then(made=>{
// write to directory here
})
