我在AWS Lambda上使用了Sharp,并且效果很好,但是,当我尝试添加水印时,它会给出一个错误。

它在本地但在AWS lambda上运行良好;它给出了这个错误
The input file is missing or of an unsupported image format
水印和lambda函数位于同一存储桶中

我该如何解决
答案 0 :(得分:1)
要添加水印,您可以使用Python 3.6.7 (default, Oct 22 2018, 11:32:17)
[GCC 8.2.0] on linux
Type "help", "copyright", "credits" or "license" for more information.
>>> def f():
... print("Hello")
...
>>> callback = f
>>> callback()
Hello
>>> callback2 = lambda: f
>>> callback2()
<function f at 0x7fafacc10c80>
>>>
。
composite()
然后您可以使用FTP和缓冲区获取水印,然后在 let sharp = require('sharp');
let imageBuffer = null;
await sharp(buffer)
.composite([{ input: './watermark.png', gravity: 'center' }])
.sharpen()
.withMetadata()
.toBuffer()
.then(function(outputBuffer) {
imageBuffer = outputBuffer;
});
return imageBuffer;
中传递缓冲区。
