需要一个参数，base64编码的字符串，可由步骤一得到。public static InputStream BaseToInputStream(String base64string){ ByteArrayInputStream stream = null; try { BASE64Decoder decoder = new BASE64Decoder(); byte[] bytes1 = decoder.decodeBuffer(base64string); stream = new Byte...
$base64Image = "data:image/png;base64,iVBORw0KG..."; // Base64编码的图像数据 $imageData = base64_decode($base64Image); 2.保存图像到本地文件:现在,我们已经有了图像的二进制数据,我们可以将其写入一个文件。这可以通过使用PHP的内置函数file_put_contents()来实现。 $outputPath = "/path/to/...
