Question

我有使用base64编码的未知数量的图像。它们采用以下格式：

我可以使用以下方法成功解码它们：

    imageToShow = base64.b64decode(image0)
    stream1 = cStringIO.StringIO(imageToShow)
    bmp1 = wx.ImageFromStream(stream1)
    self.image_spot0.SetBitmap(wx.BitmapFromImage(bmp1))

    imageToShow = base64.b64decode(image1)
    stream1 = cStringIO.StringIO(imageToShow)
    bmp1 = wx.ImageFromStream(stream1)
    self.image_spot1.SetBitmap(wx.BitmapFromImage(bmp1))

    imageToShow = base64.b64decode(image2)
    stream1 = cStringIO.StringIO(imageToShow)
    bmp1 = wx.ImageFromStream(stream1)
    self.image_spot2.SetBitmap(wx.BitmapFromImage(bmp1))

由于可能有3个，100个，300个或者为什么不是5000个编码图像，我希望能够使用循环处理解码。

当我尝试使用以下代码时：

    image_group = ['image0', 'image1', 'image2']
    for img in image_group:
        imageToShow = base64.b64decode(img)

我得到填充错误，我假设数据没有传递给base64.b64decode（），只有实际字符串“image0”。任何帮助将不胜感激。

Answer 1

您将变量名称字符串文字与相同的值混合在一起。

解决方案是书面形式：

image_group = ['image0', 'image1', 'image2']

您甚至可以通过组合声明来减少它：

image_group = [
    "iVBORw0KGgoAAAANSUhEUgAAA...",
    "iVBORw0KGgoAAAANSUhEUgAAA...",
    "iVBORw0KGgoAAAANSUhEUgAAA..."
]

使用循环解码base64图像
