B4J Question How to extract text content from webview page ?

[RushilD]

Hello All,

I am working on a simple test project where I load a login page using webview. This works file.

Currently I do the following:
1. Load a login page using webview
2. After successful login , the page displays the following text in the webview:

{"expires_in":300,"refresh_expires_in":15551999,"refresh_token":"eyJhbGciOiJIUzI1NiIsInR5cCIgOiAiSldUIiwia2lkIiA6ICJjYjY5MzYyYi03NDYwLTQ5NmUtOTNiMS0yZTVjNDk1MDcxY2IifQ.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.j42m5A51NQauY_Z5ju9HbUtrbQa5E7kD2KGFGnzVdwo","token_type":"Bearer","id_token":"eyJhbGciOiJSUzI1NiIsInR5cCIgOiAiSldUIiwia2lkIiA6ICJUb1FBeE5QRFpMM1cxMVJkcGY3d1l2NjJfTUJrbmxKYlZrYTJxRm84RmRRIn0.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.T9T-6gLwzyFzK2LKGLQfhy3M_VmZ5yidhhL6-nNhbRDsb8O5udsJQLIoC2wZY0GyRS_lJc1EBhN1IpAPnrFeVTjiplEF72-aoreLwOhORA-0wtv72swOKR03GwkWm6hO_ONFVkHGg5lfa1aJwvtX8g7hyn-lV8j90YYWr5LpxQ9minKBiFCwUUbXJ_H9jhpuUHVKxEwsdKRMd7k4xu4QoVsP31fs0ckJ_uLBFz5LHqm9RCmDSia5ZXG-RQNZrfGYaLumo1jNX3mG5uEfeh3ET4A2Nx9rBSts-_DGF89fOBOYBYvLEJWc7YkHyd5FPiJ9kJiKHx066jH079qZpgfx6w","not-before-policy":0,"session_state":"94a41337-dc84-4f8e-a6c9-f897d63dbe18","scope":"openid profile","tandc_accepted":true,"partialLogin":false}

Question:
How can I extract the "refresh_token" and save it ?

Use this tool to parse the JSON string you get from the website
https://www.b4x.com/android/forum/threads/jsontree-tool-to-help-with-json-parsing-b4a-b4j.35963/
And you will get the code to obtain all the values.
You can use even this online tool to obtain the same code

Dim parser As JSONParser
parser.Initialize(<text>)
Dim jRoot As Map = parser.NextObject
Dim refresh_token As String = jRoot.Get("refresh_token")
Dim partialLogin As String = jRoot.Get("partialLogin")
Dim refresh_expires_in As Int = jRoot.Get("refresh_expires_in")
Dim not-before-policy As Int = jRoot.Get("not-before-policy")
Dim scope As String = jRoot.Get("scope")
Dim id_token As String = jRoot.Get("id_token")
Dim token_type As String = jRoot.Get("token_type")
Dim session_state As String = jRoot.Get("session_state")
Dim tandc_accepted As String = jRoot.Get("tandc_accepted")
Dim expires_in As Int = jRoot.Get("expires_in")

Thank you for the response but how do I extract the text from here:

I am calling
WebView1.LoadUrl("https://xxxxxxxxxxxxxxxxx/v3/test/login?getHttpLogin=true")

which opens a login page. I then enter the credentials. pressing login show the below text in the webview. Now I need to extract the contents

I am calling
WebView1.LoadUrl("https://xxxxxxxxxxxxxxxxx/v3/test/login?getHttpLogin=true")

You should not use a webview and instead use directly okhttputils2 and make the request with it.
It is easy to get the result with okhttputils.

 

[behnam_tr]

use okhttputils library

Dim j As HttpJob
j.Initialize("", Me)
j.Download("https://www.google.com")
Wait For (j) JobDone(j As HttpJob)
If j.Success Then
   Log(j.GetString)
End If
j.Release
