Base64 String in JSONRequest Java

Question

I'm handling a Web Service and need some help. The process is that a pdf will be encoded with base64 and sent to my web service. I will then decode it back into a pdf and place it in the appropriate folder. The issue is that the request needs to contain the actual giant base64 string. First question is is this possible. Second, I am using postman to make the requests and was wondering how to even copy the base64 string into it. It seems there's a string limit. Any help would be greatly appreciated.

Answer 1

I don't know about postman but I can suggest to use JAX-RS and implement a ReaderInterceptor and a WriterInterceptor using Base64.Decoder#wrap respectively Base64.Encoder#wrap .

Otherwise, maybe postman has similar features?

Use streams like these as much as possible to reduce memory usage.

Answer 2

Alright it just seems to be an issue with Postman. When you place a string of that size it will give you errors and only put a certain length per line. It will still receive the entire string. I am able to receive it and decode it. Thank you all for your help!
