It can transform incoming binary files into base64 encoded strings before passing on to a Lambda function, and transform base64 encoded Lambda resutls into binary files. Similarly, although the documentation suggests that multiple content types can be specified in the Accept header for binary responses, it seems that this breaks the conversion.
This makes the current implementation useless for browsers, which by default request complex Accept headers. Claudia API Builder makes it easier to handle binary content by doing several things automatically for you:. To respond with binary content, make sure to set the response success. Claudia API Builder will automatically convert a binary buffer to a base64 string. You can also use the binary support to process incoming binary files.
Claudia API Builder will populate request. For example, we can use the ImageMagick identify tool to get basic information about image files.
This example will save the incoming file, execute identify , clean up, and return the result. No specific API endpoint configuration is needed here. To use this service, make sure to include the Content-Type header into your request. We can combine both techniques to create a service for thumbnails. The endpoint will receive an image, resize it, and return the result. Note that we can directly store request body into a file Claudia API builder will process and convert the incoming body into a binary buffer , and that we can directly return the results of a binary file read Claudia API Builder will convert it into a base64 string.
To see this in action, check out the Binary Content Handling example project. Once a month, high value mailing list, no ads or spam. Check out the past issues. Incoming request are transformed into base64 strings if: It will automatically decode incoming baseencoded bodies into a Buffer object so you can directly save it to a file, for example. It will automatically encode Buffer results into base It allows you to easily set incoming request and response content handling.
Configuring an API Use api. If you plan to use one of those types, you do not need to call setBinaryMediaTypes. Use requestContentHandling in the handler configuration to set the required incoming binary content handling behaviour API Gateway Integration content handling.
