Question

我想显示上传的图片，但即使我登录也遇到403错误。上传工作很好，downloadURl没问题。我已经通过身份验证（上传成功显示我已经签名）但是我无法显示上传的图片。

storage.child(file_name).put(event_image).then(function(snapshot) {
        console.log('Uploaded a blob or file!');
        var img_src = snapshot.downloadURL;
        $('img#uploaded').attr('src',img_src);
});

使用此链接：https://firebase.google.com/docs/storage/web/download-files#download_data_via_url

storageRef.child('images/stars.jpg').getDownloadURL().then(function(url)     {
    // `url` is the download URL for 'images/stars.jpg'

   // This can be downloaded directly:
   var xhr = new XMLHttpRequest();
    xhr.responseType = 'blob';
    xhr.onload = function(event) {
    var blob = xhr.response;
    };
    xhr.open('GET', url);
    xhr.send();

     // Or inserted into an <img> element:
      var img = document.getElementById('myimg');
       img.src = url;
     }).catch(function(error) {
     // Handle any errors
});

404错误显示来自firebase存储的图像
