Hello
I'm absolute new in PureBasic and struggle to get a working http post request.

This is the requirement I got for the http post:

URL: https://enlighten.enphaseenergy.com/log ... =xxxxxxxxx

Header:
"Accept": "application/json",
"content-type": "application/x-www-form-urlencoded",
"Cache-Control": "no-cache"

Json Body:
"user[email]": username,
"user[password]": password

I I tried a few things but nothing worked, like this:

Code: Select all

NewMap Header$()
  Header$("Accept") = "application/json"
  Header$("content-type") = "application/x-www-form-urlencoded"
  Header$("Cache-Control") = "no-cache"
  
NewMap Body$()
 Body$("user[email]") = "my_name@gmail.com"
 Body$("user[password]") = "xxxxxxxxxx" 
  
result = HTTPRequest(#PB_HTTP_Post, "https://enlighten.enphaseenergy.com/login/login.json?serialnumber=1234567890", Body$(), 0, Header$())
    Debug "StatusCode: " + HTTPInfo(result, #PB_HTTP_StatusCode)
    Debug "Response: " + HTTPInfo(result, #PB_HTTP_Response)

I expect to get a kind of session_id back. I guess, I made something wrong with the body, which should be JSON....?

Has anybody some ideas?
Kind regards
Roman

You need to create a json first. You have a map, but HttpRequest wants the body to be a pure string.

Thank you.
I tryied something like this, but have still no success:

Code: Select all

If CreateJSON(0)
    Account = SetJSONObject(JSONValue(0))
    SetJSONString(AddJSONMember(Account, "user[email]"), "my_name@gmail.com")
    SetJSONString(AddJSONMember(Account, "user[password]"), "xxxxxxxx")
    Body$ = ComposeJSON(0, #PB_JSON_PrettyPrint)
EndIf

NewMap Header$()
  Header$("Accept") = "application/json"
  Header$("content-type") = "application/x-www-form-urlencoded"
  Header$("Cache-Control") = "no-cache"
  
  
result = HTTPRequest(#PB_HTTP_Post, "https://enlighten.enphaseenergy.com/login/login.json?serialnumber=1234567890", Body$, 0, Header$())
    Debug "StatusCode: " + HTTPInfo(result, #PB_HTTP_StatusCode)
    Debug "Response: " + HTTPInfo(result, #PB_HTTP_Response)

Code: Select all

username$ = "uname"
password$ = "pword"

Body$ = ~"{\"user[email]}\": \"" + username$ + ~"\","
Body$ + ~"\"user[password]\": \"" + password$ + ~"\"}"

Debug Body$

You forgot FreeJSON()

Maybe you need to encode the body cause of the @

Try UrlEncoder() because this is recommended by your header.

Best is to make a real access in a web browser and open before the developer Tools with F12
Then you can inspect what is sendet, or use wireshark and replace https with http to see the request.

Isn't it this:

That's right which I find for along time !!

Thanks to all.

I know the API documatation - and unfortunately, none of your tips worked.

I used the Postman API Tool https://www.postman.com/home to check the specified values for the header and the body - and it works very well. it even works, when the body format is "form-data" instead of "x-www-form-urlencoded".

Here the same URS, header and body, entered in Postman

I clearly get a success and the expected "session_id".

So there must be indeed something wrong with my PureBasic approach.

Form data isn't json. "say=Hi&to=Mom" that's how form data looks.

I was just about to say, since when is the request a json ? the result is a json!

Thank you very much, but you are speaking a bit too "high level" for me...
In my opening post, I didn't code the body as JSON but rather as a map like the header - but that didn't work either.
How do I have to code the body correctly, I'm clueless...?

BTW, I'm not a programmer, neither professionally nor privately. Yes, I've done a few small things in AutoIt, PowerShell, AVR-C and JavaScript - but I'm not really good or experienced at any of them...

You wrote "Json Body:"

that's why we assumed you wanted json. Anyway, you'd simply stitch together a string.

Something like this

Code: Select all

URLEncoder("user[email]") + "=" + URLEncoder(usermail$) + "&" + URLEncoder("user[password]") + "=" + URLEncoder(password$)

I'm very sorry about that. I apologize.
I definitely got this requierements which mentioned "JSON Body". Of course I see now, this was misleading extremely, but I didn't know better.
Sorry again!

But now it works! It's great when experienced users can solve a problem so quickly (as long as they get correct information

)
Many thanks to all, und you, Daniel.

Kind regards
