[英]How to Upload Images to Firebase Storage and Get Image's Download URL's When Using Dropzone in React.js
我的反應網站中有一個<Dropzone/>
組件,它允許我的用戶通過單擊或拖放來上傳多個圖像。
當我上傳圖像時,它們被保存在我的 firebase 存儲中,但沒有設置每個單獨圖像的 URL,我收到 firebase 錯誤,內容如下:
"Uncaught (in promise) FirebaseError: Firebase Storage: Object 'propertyImages/Picture1.png+4b80d-6dd0-4b40-cadc-8e7845677bbd' does not exist. (storage/object-not-found)
{
"error": {
"code": 404,
"message": "Not Found."
}
}"
我不知道為什么它沒有為每個圖像設置 url,我相信這是因為它覆蓋了以前的下載 url。 如何使 Dropzone 正常工作?
我究竟做錯了什么?
這是我的代碼:
import Dropzone, {useDropzone} from "react-dropzone"
const [urls,setUrls] = useState([]);
const { getRootProps, getInputProps, isDragActive } = useDropzone({ onDropAccepted: onFilesDrop, maxFiles: 5 });
function onFilesDrop(files) {
files.map((item, index) => {
let uploadTask = storage.ref(`propertyImages/${item.name}+${uuid()}`).put(item);
uploadTask.snapshot.ref.getDownloadURL().then(function (downloadURL) {
setUrls(prevState => {
return [...prevState, downloadURL]
})
})
})
}
return (
<CardTitle className="mb-3 h4">Property Images (MAX IMAGES 5)</CardTitle>
<div className="dropzone" >
<Dropzone
onDrop={acceptedFiles =>
onFilesDrop(acceptedFiles)
}
>
{({ getRootProps, getInputProps }) => (
<div>
<div
className="dz-message needsclick"
{...getRootProps()}
>
<input {...getInputProps()} />
<div className="dz-message needsclick">
<div className="mb-3">
<i className="display-4 text-muted bx bxs-cloud-upload" />
</div>
<h4>Drop files here or click to upload.</h4>
</div>
</div>
</div>
)}
</Dropzone>
)
更新文件刪除 function
function onFilesDrop(files) {
files.map((item, index) => {
let uploadTask = storage.ref(`propertyImages/${item.name}+${uuid()}`).put(item);
console.log(uploadTask);
uploadTask.on(
"state_changed",
snapshot => {
},
error => {
console.log(error);
},
async () => {
await storage
.ref("images")
.child(item.name)
.getDownloadURL()
.then(urls => {
console.log(urls) //log url if you want
setUrls((P) => [...P, urls]);
})
}
)
})
