我工作的谷歌联系人API和我收到的所有数据和发送的字符串JSON(JavaScript)的,但是当我从通讯录中获得的图像,我可以接收图像。 我怎么可以把它送到JSON? 如何发送的图像文件的URL? (我可以用路标?)
if (photoLink.getEtag() != null) {
GDataRequest request = myService.createLinkQueryRequest(photoLink);
request.execute();
// No Authentication header information
InputStream stream = request.getResponseStream();
Image image= ImageIO.read(stream);
}
如果你想发送编码为使用JSON数据的实际图像,你可以发送HTML img
标签与src
包含编码的图像数据,像这样的属性:
<img src="data:image/png;base64,R0lGODlhEAAOALMAAOazToeHh0tLS/7LZv/0jvb29t/f3//Ub/

You should simply use a servlet for sending images and just send some url variable in JSON. (like ?pic_id=034enifuwbf0329
.
You could use inline image, but that would fail miserably on certain IE versions, while the other solution is browser-agnostic.
