在网址上： {{user.Photo}}

在ng-repeat循环中，我有：

<img data-ng-src="data:image/png;base64,{{user.Photo}}" data-err-src="images/png/avatar.png"/>

但结果我看到了：

data-ng-src="data:image/png;base64,http://location.com/files/idididididid"

但为什么？如何显示我的图像数据？

一尘不染

如果映像来自远程服务器，则可以像下面这样在控制器中获取base64内容：

$http.get($scope.user.photo).then(function(response) {
    $scope.user.data = response.data;
});

然后在视图上显示

<img data-ng-src="data:image/png;base64,{{user.data}}" data-err-src="images/png/avatar.png"/>

当图像位于本地磁盘/电话上时，首先您可以从 FileReader

var fileInput = document.getElementById("myfileinput");

// files is a FileList object (similar to NodeList)
var files = fileInput.files;
$scope.imageSrc = files[0].getAsDataURL();

然后将绑定$scope.imageSrc为<img ng-src="imageSrc" >
