I asked a similar question here: How do I upload a file with metadata using a REST web service? You basically have three choices: Base64 encode the file, at the expense of increasing the data size by around 33%, and add processing overhead in both the server and the client for encoding/decoding. Send the file … Read more
JSON does not allow real line-breaks. You need to replace all the line breaks with \n. eg: “first line second line” can saved with: “first line\nsecond line” Note: for Python, this should be written as: “first line\\nsecond line” where \\ is for escaping the backslash, otherwise python will treat \n as the control character “new … Read more
NOTE: When I first spent time reading about REST, idempotence was a confusing concept to try to get right. I still didn’t get it quite right in my original answer, as further comments (and Jason Hoetger’s answer) have shown. For a while, I have resisted updating this answer extensively, to avoid effectively plagiarizing Jason, but … Read more

You need to set your content-type to application/json. But -d (or –data) sends the Content-Type application/x-www-form-urlencoded, which is not accepted on Spring’s side. Looking at the curl man page, I think you can use -H (or –header): -H “Content-Type: application/json” Full example: curl –header “Content-Type: application/json” \ –request POST \ –data ‘{“username”:”xyz”,”password”:”xyz”}’ \ http://localhost:3000/api/login (-H … Read more
No. JSON is data-only. If you include a comment, then it must be data too. You could have a designated data element called “_comment” (or something) that should be ignored by apps that use the JSON data. You would probably be better having the comment in the processes that generates/receives the JSON, as they are … Read more
