Android Question (Solved)WebView Post

[iCAB]

Hi Guys

I am looking for an example that shows how to invoke a login page in webview. The page requires POST and passing the user name and password in json format.

Thanks in advance

Why use WebView for this? You should send POST requests with OkHttpUtils2.

Hi Erel,
The requirements are as follows:

• we must load an existing web page in the browser
• pass the user's email address
• the user enters his password and clicks login
• if login is successful, the page returns a security token as a cookie
• we must capture the token for all future communications (which will be using OkHttpUtils)

That's why I was thinking that Webview is the way to go

Thanks

So, just get the cookie from Webview after login.

That's not the issue at all.
The issue is how to invoke the page with POST in webview

Not sure how to do that, can you please clarify.

Also I was checking this:
https://stackoverflow.com/questions/39506246/how-to-post-data-for-webview-android

is there no similar code for B4A webview?

Thanks

WebView will send post requests automatically if the html includes a form. Just like any browser.

Though I'm not using it any more (replaced such requests with okHttpUtils2), here's how I did it in the past:

Private tempPostUrl As String="yourURL"
Private tempPostString As String="yourPostData after encoding URL"
Private bytesOfPOstRequest() As Byte
bytesOfPostRequest=tempPostString.GetBytes("UTF8")
Private jo As JavaObject=yourWebView
jo.RunMethod("postUrl",Array As Object(tempPostUrl,bytesOfPostRequest))

Thanks a lot, sounds good I will give it a try.

One question with regards to the above. The code says "after encoding the URL"

Private tempPostUrl As String="yourURL"
Private tempPostString As String="yourPostData after encoding URL"

I see that POST data being encoded

Private bytesOfPOstRequest() As Byte
bytesOfPostRequest=tempPostString.GetBytes("UTF8")

At what point tempPostUrl is being encoded?

You have to use stringUtils (lib) for this:

Private su As StringUtils
Private tempPostString as string=su.EncodeUrl(originalPostString,"UTF8")
