javascript - 如何从 Firebase 存储中检索图像 url？

Question

我直接从 Firebase 文档中获得了此代码:

// Create a reference to the file we want to download
  var user = firebase.auth().currentUser.uid;
  var storageRef = firebase.storage();
  var pathReference = storageRef.ref('/' + user + '/profilePicture/' + image.name);

  //var starsRef = storageRef.child('/' + user + '/profilePicture/' + file.name);

  // Get the download URL
  pathReference.getDownloadURL().then(function(url) {
  // Insert url into an <img> tag to "download"
      $scope.imageUrl = url;
      console.log($scope.imageUrl);
  });

但是我不知道要在 html 文件中写什么才能显示图像......有什么帮助吗？

只需将结果放入 Controller 的变量中以及 HTML 上的 ng-src 中即可。

最好是使用服务来获取 URL，而不是直接在 Controller 中获取。

Controller

app.controller('MyController', ['$scope', function($scope) {
    // Create a reference to the file we want to download
    var user = firebase.auth().currentUser.uid;
    var starsRef = storageRef.child('/' + user + '/profilePicture/' + file.name);

    // Get the download URL
    starsRef.getDownloadURL().then(function(url) {
    // Insert url into an <img> tag to "download"
        $scope.imageUrl = url;
    });
}]);

HTML

<img ng-src="{{imageUrl}}"/>
