Question

我使用cordova-plugin-camera要求用户从PHOTOLIBRARY中选择一张图片。我正在使用Android

进行测试

我传递给相机的选项是：

options: {
                sourceType: Camera.PictureSourceType.PHOTOLIBRARY,
                destinationType: Camera.DestinationType.FILE_URI
            }

然后我成功回电我得到以下URI：

content://media/external/images/media/14555

但是当我尝试使用它在html上显示为：

<img src="content://media/external/images/media/14555"/>

它不起作用并显示此消息

无法加载资源：服务器响应状态为404 （未找到）

我已尝试过所有内容，但无法显示图片。还有一件事我不能在相机插件上使用DATA_URL因为我需要访问实际文件。

Answer 1

它作为404响应，因为在应用程序的上下文中uri是无关紧要的，因为webview无法解析uri，你需要使用某个文件API插件导入文件然后才能工作.Hope它会有所帮助。

Answer 2

我使用cordova的File API插件实现了这个，
