android - Worklight - MTOM 附件图像文件

Question

作为我的 worklight 项目的一部分，我们正在调用一个 Web 服务，该服务将图像文件作为 MTOM 附件发送。有没有办法解析图像内容并转换为 JSON 对象？下面是我配置服务调用的适配器中的一段代码:

 var input = {      
 method : 'post',
 returnedContentType : 'plain',   
 path: '/contentaccess-ws/ContentAccessDocument_1',     
 body : {       
  content: retrieveDocumentRequest.toString(),      
  contentType : 'application/soap+xml; charset=utf-8'   
  }
 };

下面是响应:

--MIMEBoundary_89c65bb62e242e7ee812d596799431326111505dc1baf518
Content-Type: application/xop+xml; charset=utf-8;           
type="application/soap+xml"

我尝试将“returnedContentType”作为“JSON”但没有用(服务向我抛出错误)。

感谢任何指点!

适配器不会为您执行此操作。

您需要做的是从适配器获取响应，并使用能够将图像附件解码为真实图像的框架。

通常不使用 MOTM。相反，您将图像用 base64 编码为字符串，然后将字符串解码回图像。
