Http Request does not work when uploading files using multipart/form-data

Can you clarify how is the problem related to IntelliJ IDEA functionality?

Ok, What I mean is, I hope I can ask how to upload files using Http Request. According to the writing in my picture, it does not work correctly.

In addition, my English is not very good, thank you very much for your help.

Please use specific development forums or stackoverflow for the question - you will have better chances for an answer there as this is not IDE-specific problem.

Beter late then never :)   

It's

- form-datA not form-date
- you miss a ";" behind file

Content-Disposition: form-date; name="file" filename="img.gif"

Content-Disposition: form-data; name="file"; filename="img.gif"
