我正在为应用程序使用firebase存储,以便我可以存储我想要在弹出窗口中显示的图像。现在我可以参考图像,但我无法使用URL
获取图像的getDownloadURL()
。
我已尝试过所有内容,但似乎无法获取网址,只会在控制台中显示错误Error: Reference.push failed: the first argument contains undefined in property 'markers.imageURL.i'", AND " Failed to load resource: the server responded with a status of 404 (HTTP/2.0 404)
任何人都知道为什么?
这是我的代码片段。 imageFURLY是不返回URL的内容。
document.getElementById('infowindowSubmit').addEventListener('click', function (event, imageFURL) {
// This function saves the newly created marker and the infowindow information when
//the 'Submit' button is clicked.
var fileInput = document.getElementById('fileInput');
var file = fileInput.files[0];
//Create storage ref
var storageRef = firebase.storage().ref('markerpics/' + file.name);
var task = storageRef.put(file);
console.log('storageRef ', storageRef)
imageFURL = storageRef;
console.log('imageFURL ', imageFURL);
//Upload file
imageFURLY = imageFURL.getDownloadURL();
console.log('imageFURLY ', imageFURLY);
//Variables that store data inputted in infowindow
var postName = document.getElementById('formName');
var postNameF = postName.value;
var postMessage = document.getElementById('formMessage');
var postMessageF = postMessage.value;
var postImageRef = imageFURLY;
console.log('postImageRef - URL: ', postImageRef);
var latitude = location.lat(location);
var longitude = location.lng(location);
//Closes markers open infowindow
largeInfowindow.close(map, marker);
//Sets markers infowindow to NEW content
console.log('Setting infowindow content!! ');
largeInfowindow.setContent('<div>' + '<div>Name: ' + postNameF + '</div><br>' + '<div>Message: ' + postMessageF + '</div><br>' + '<div>Image: ' + '</div>' + '<img style="height: 100px; width: 100px;" src="' + postImageRef + '" alt="Mountain View">' + '<br>' + '</div>');
console.log('Set infowindow content!! ');
largeInfowindow.open(map, marker);
// Make sure the marker property is cleared if the infowindow is closed.
largeInfowindow.addListener('closeclick', function () {
largeInfowindow.marker = null;
});

我愿意打赌你试图获取一些尚不存在的网址。
document.getElementById('infowindowSubmit').addEventListener('click', function (event, imageFURL) {
// This function saves the newly created marker and the infowindow information when
//the 'Submit' button is clicked.
var fileInput = document.getElementById('fileInput');
var file = fileInput.files[0];
//Create storage ref
var storageRef = firebase.storage().ref('markerpics/' + file.name);
到目前为止一切都很好
var task = storageRef.put(file);
推迟了。 task
是一个承诺。
console.log('storageRef ', storageRef)
imageFURL = storageRef;
console.log('imageFURL ', imageFURL);
//Upload file
imageFURLY = imageFURL.getDownloadURL();
put
尚未执行,但您正在调用getDownloadURL()
。因此,它还不存在!你得到404。
以下是解决问题的方法:
document.getElementById('infowindowSubmit').addEventListener('click', function (event, imageFURL) {
// This function saves the newly created marker and the infowindow information when
//the 'Submit' button is clicked.
var fileInput = document.getElementById('fileInput');
var file = fileInput.files[0];
//Create storage ref
var storageRef = firebase.storage().ref('markerpics/' + file.name);
var task = storageRef.put(file);
task.then(function(snapshot) {
console.log('storageRef ', storageRef)
imageFURL = storageRef;
console.log('imageFURL ', imageFURL);
//Upload file
imageFURLY = imageFURL.getDownloadURL();
// ...
});

let file = await bucket.upload(fromFilePath, {destination: toFilePath});
const trimUrl = file[0].metatata.mediaLink
