在微信浏览器中使用相机

如果你的手机是安卓系统，并且使用的是微信内置的浏览器浏览WeUI生成的网页，你会发现Uploader只能从相册中选择图片上传，无法使用相机拍照上传。

要解决这个问题很简单， 只需将Uploader的Accept属性设置为"image/*"，例如：

Select Case e.Path

    Case "test.htm"
        Dim wb As New weui
        wb.AddForm("","form1","test.htm")
        With wb.AddInputGroup("form1","ipg22","文件上传")
            With .AddUploader("up2","图片",True)
                .Accept = "image/*"   '允许使用相册和相机
            End With
        End With
        With wb.AddButtonGroup("form1","btg1",True)
            .Add("btn1", "确定", "submit")
        End With
        e.WriteString(wb.Build)
End Select

如果希望不能从相册选择，而是直接拍照上传，可以再将Capture属性设置为"camera"，例如：

Select Case e.Path
    Case "test.htm"
        Dim wb As New weui
        wb.AddForm("","form1","test.htm")
        With wb.AddInputGroup("form1","ipg22","文件上传")
            With .AddUploader("up2","图片",True)
                .Accept = "image/*"  
                .Capture = "camera" '只能拍照上传
            End With
        End With
        With wb.AddButtonGroup("form1","btg1",True)
            .Add("btn1", "确定", "submit")
        End With
        e.WriteString(wb.Build)
End Select
