exec.Command Escaping Variables with JSON Payload - json

Question

Thank you in advance as I have spent 2 days on this. Here is a working curl command.
curl -ku login:pass -X POST -H 'Content-Type: application/json'-d'{"type":"page","title":"Testpage","space":{"key":"ITDept"},"body":{"storage":{"value":"<p>Blank Page.</p>","representation":"storage"}}}' https://confluence/rest/api/content
I need to get this to execute with exec.Command.
Given that now in Go I have tried escaping and all sorts of other means to get this to work. The issue is more than likely this ridiculous JSON string that is required. I have the JSON string saved into a var now to try it that way.
jsonPayload := '{"type":"page","title":"Testpage","space":{"key":"ITDept"},"body":{"storage":{"value":"<p>Blank Page.</p>","representation":"storage"}}}'
execCmd := "bash", "-c", "curl -ku login:pass -X POST -H 'Content-Type: application/json' -d" jsonPayload "https://confluence/rest/api/content"
So the jsonPayload is the argument to -d. I have tried this using the Marshal json/encoding and the net/http package and it goes through but something about how that stdlib is sending it causes the API to state it is the wrong format.
I also have tried this with this and the curl copied out of the println works but when actually ran in golang it fails with incorrect format.
env := os.Environ()
curlCmd, err := exec.LookPath("curl")
if err != nil {
fmt.Println("Path not found to binary!")
panic(err)
}
args := []string{"curl", "-ku", "login:pass", "-X", "POST", "-H", "'Content-Type: application/json'", "-d", payloadJson, "https://confluence/rest/api/content"}
execErr := syscall.Exec(curlcmd, args, env)
if execErr != nil {
panic(execErr)
}
fmt.Println(curlCmd)
When the curlCmd from that last line there prints it can be copied and pasted into the terminal and it works however when going through golang it comes with a format not supported. Any help would be greatly appreciated.

Try this:
payload := `{"type":"page","title":"Testpage","space":{"key":"ITDept"},"body":{"storage":{"value":"<p>Blank Page.</p>","representation":"storage"}}}`
cmd := exec.Command("curl", "-ku", "login:pass", "-X", "POST", "-H", "Content-Type: application/json", "-d", payload, "http://localhost:8080/confluence/rest/api/content")
p, err := cmd.CombinedOutput()
if err != nil {
log.Fatal(err)
}
fmt.Printf("%s\n", p)
Important change from code in the question:
Run command directly instead of using bash.
Specify host name in URL.
Properly quote the string.
BTW, you can also an interpreted string literal:
payload := "{\"type\":\"page\",\"title\":\"Testpage\",\"space\":{\"key\":\"ITDept\"},\"body\":{\"storage\":{\"value\":\"<p>Blank Page.</p>\",\"representation\":\"storage\"}}}"
