这是我的vb代码。 我当然先正确登录。

Dim oRequest As New WinHttp.WinHttpRequest
Dim file as string = "C:\Users\Guile\Documents\file.txt"

oRequest.Open("POST",jiraURL)
oRequest.SetRequestHeader("X-Atlassian-Token","no-check")
oRequest.SetRequestHeader("Content-Disposition","form-data; name=""file""; filename=""file.txt""")
oRequest.SetRequestHeader("Content-Type","text/plain")
oRequest.Send(file)
