通过AWS API Gateway发布表单数据和二进制数据 [英] Posting form-data and binary data through AWS API Gateway
问题描述
我正在尝试通过AWS API Gateway将"mutlipart \ form-data"发布到我的EC2实例，但是我找不到解决方法.有一种方法可以使用"application/x-www-form-urlencoded"和Mapping Tamplate发布数据以将其转换为JSON，但是我想仍然缺少像图像文件这样的二进制数据.我有什么想念的吗?
I'm trying to POST "mutlipart\form-data" to my EC2 instance through AWS API Gateway, but I couldn't find a way to this. There is a way to post data using "application/x-www-form-urlencoded" and Mapping Tamplate to convert it to JSON but still posting a binary data like an image file is missing I guess. Is there anything I'm missing ?
我找到了另一种方法:
我将图像转换为base64字符串，然后将其发布为内容类型为"application/x-www-form-urlencoded".通过这种方式，我将整个图像作为字符串发送.收到消息后，我可以将其转换回PHP中的图像.我只能发现，当我将图像转换为base64时，它的大小会变大一些.除此之外，我找不到其他缺点.如果可以，请与我分享?
I convert the image to base64 string then POST it as with content type "application/x-www-form-urlencoded". By this way I'm sending whole image as string. After I got the message I can convert it back to image in PHP. Only down side of this I could find is when I convert image to base64 its size gets a bit bigger. Other than that, I couldnt find any other downside. If there is could you please share with me ?
推荐答案
此处是Api Gateway团队.
Api Gateway team here.
目前不支持二进制数据，但已将其保存在我们的积压中.有几个客户要求这样做.
一些客户在映射模板中成功使用了base64 util，这可能会使它为您工作:
Some customers have had success using the base64 util in the mapping templates which may get it working for you: http://docs.aws.amazon.com/apigateway/latest/developerguide/api-gateway-mapping-template-reference.html#util-template-reference
除此之外，您还必须等待官方支持.
Other than that you'll have to wait for official support.
