显示来自分贝角局部视图二进制图像 [英] display binary image from db to angular partial view
问题描述
我是想用来显示JSON对象从网络API请求返回来内图像。我能够在我的角度部分显示字符串，数字和日期/时间，但无法得到显示图像。
这里是其中包含我演讲的题目中的每个字段我的JSON对象（模型）类
I was trying to display image which is coming within the json object returning from an web api request. I'm able to display string, number and date/time in my angular partial but couldn't get the image displaying. here is my json object which contains each field of my topic (model) class

和这里是我的角度HTML部分：
and here is my angular html partial:
<a data-ng-href="#/message/{{ i.id }}">{{ i.title }}</a>
</div>
<div class="date span2">
{{ i.created | date:"medium" }}
</div>
<div class="contents span12">
{{ i.body }}
</div>
<img ng-alt="" src="{{'data:image'+i.photofile}}" /> </div>
`
既然我能得到其他属性的工作，我的棱角分明的工厂和控制器应工作。是否有什么毛病我在显示图像的角局部视图语法？谢谢
Since i can get other attributes working, my angular factory and controller should be working. Are there anything wrong with my syntax in angular partial view for displaying images? Thanks

您不应该是采用了棱角分明的前pression作为值时，使用
的src属性。使用 NG-SRC 相反，它将保证图像不显示角有机会取代前pression之前。
You shouldn't be using the
srcattribute when using Angular expression as the value. Use ng-src instead, it will ensure the image don't show up before Angular has a chance to replace the expression.如果你已经显示的样本有效载荷完成时，会形成数据URI的方式是不完整的。根据图像的格式，标题应为
If the sample payload you've shown is complete, the way you are forming the data URI is incomplete. Depending on the format of the image, the header should look like
data:image/png;base64,[things in the JSON]您可以阅读更多关于格式 rel=\"nofollow\">
