Wordpress REST Api Authorization Help

james_sgp · Jul 12, 2023

Hi, I am now working on using the WP REST API to confirm login details of my apps user. I`m using the following code, which is partially working; but I`m not getting the expected response from the API.

The code I`m using is

B4X:

Private Sub B4XPage_Created (Root1 As B4XView)
    Root = Root1
    Root.LoadLayout("MainPage")
    
    Dim SU As StringUtils
    Dim s As String  =  "aaaa:bbbb"
    Dim e As String  = SU.EncodeBase64(s.GetBytes("UTF8"))
    
    Dim j As HttpJob
    j.Initialize("log-in", Me)
    j.PostString("https://www.ZZZZ.com/wp-json/wp/v2/posts", "")
    j.GetRequest.SetHeader("Authorization", "Basic " & e)
    Wait For (j) JobDone(job As HttpJob)
    If j.Success Then
        Log("SUCESS : " & j.GetString)
    Else
        j.Release
        Log("ERROR : " & j.ErrorMessage)
    End If
    
End Sub

But I`m getting the response :

B4X:

ERROR : {"code":"empty_content","message":"Content, title, and excerpt are empty.","data":{"status":400}}

I have tried changing the username & password and I get a message saying incorrect UN/PW (respectively), so would appear things are too far off.

But I am expecting something like this :

B4X:

Please are you following the API Documentation?

Getting post list, single posts, post categories, comments etc does not need any username and password.

[CODE lang="b4x" title="POST Endpoint"]https://example.com/wp-json/wp/v2/posts[/CODE]

The end point in your code is pointing to POSTS. If you are tryting to retrieve users, I think you should be using the USERS ENDPOINT

[CODE lang="b4x" title="Base Users endpoint"]https://example.com/wp-json/wp/v2/users[/CODE]

I`m using the indicated code from the miniOrange API Plugin, which shows I should get the attached response. I tried changing the 'post' to user, but got a no route error in response:

B4X:

ERROR : {"code":"rest_no_route","message":"No route was found matching the URL and request method.","data":{"status":404}}

Fantastic, that works...thanks...
Just for my understanding, your code seems to be waiting for responses more than mine did?

Just for my understanding, your code seems to be waiting for responses more than mine did?

If you call the process more than once, you will see the time decrease.
timeout can be 30 seconds by default, please remark it
