Character are omitting while sending request to server(Spring Boot) from client (NodeJS)

Question

I have Spring Boot and NodeJS application. Where Spring boot has set of API which are called from NodeJS application.

Because of business requirement, I am encrypting some value on Spring Boot application and sending it to NodeJS application.

In application flow, I had to send encrypted token from NodeJS application to Spring Boot application where I will be doing decryption for further processing.

Now, when I send encrypted token to Spring Boot application, I see some the character are omitting. For example, + is replaced with (new line or empty string) and due to this I am not able to perform decryption.

To be more explicit, ..1nfppOsSaMxTBIPq1x16K9L68Mo+JaaDNrgiNvkdWVOasyRCeh7rsEJEyd/syxiO.. replaced with ..1nfppOsSaMxTBIPq1x16K9L68Mo JaaDNrgiNvkdWVOasyRCeh7rsEJEyd/syxiO... I think, its something to do with encoding or escaping of character.

I tried to set content-type in request header but no luck. Can someone help me, how to fix this issue?

On NodeJS side, I am using node-rest-client to send POST request. AES algorithm is used for encryption and decryption.

It seems, your token was sent as url param, and the server tries to decode it. Just try to encode token on client side using encodeURIComponent function.
