Hello,

We are upgrading from PB19 --> PB2022.

I understand that we have to rewrite all code that uses Soup Connection to HTTP Client.

 

Can somebody, Please provide some examples.

Regards,

Marina

Hi,

I fixed The 500 issue and moved to Error 400.

Do I understand correctly?:

I need to create an XML string (ls_body) with a reference to updatecustomer function (that inside customersupd  WS).

Also, I need to provide the parameter that updatecustomer function gets.

This is the old code: luo_wsresult = p_customersupd.updatecustomer( auo_customerschema)  

 

But in a new code I have to change parameter auo_customerschema into XML structure?

This is a complicated parameter (auo_customerschema) that includes arrays, strings, numbers.... 

Is there some function that can change it to XML structure?

Do I need to write an XML with complicated structure of parameters for every case that I need to rewrite because of the upgrade?

 

And what about the value that updatecustomer function returns (luo_wsresult)?

 

Thanks,

Marina

Hi Marina

Sadly the answer to your question is no there is no function/tool to convert the complex XML for you. You will have to prepare this XML yourself. Likewise you will need to parse the XML received too. It's a real PIA, pbdom is so clunky to use but dies work.



I feel your pain.



All the best

David

if I write it like this , I get li_statusCode = 500.  what is incorrect?

 

lsp_Cnn = Create HttpClient

lsp_Cnn.SetRequestHeader("Content-Type", "text/xml")

ls_body = '<?xml version="1.0" encoding="utf-8"?>' + &
'<soap:Envelope xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" ' + &
'xmlns:xsd="http://www.w3.org/2001/XMLSchema" ' + &
'xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/">' + &
'<soap:Body>' + &
'<updatecustomer xmlns="http://tempuri.org/">' + &
'</updatecustomer>' + &
'</soap:Body>' + &
'</soap:Envelope>'

li_rc = lsp_Cnn.SendRequest("POST", ls_location, ls_body)
li_statusCode = lsp_Cnn.GetResponseStatusCode()
li_rc = lsp_Cnn.GetResponseBody(ls_response)

If li_statusCode = 200 Then

    MessageBox("Success", ls_response)
Else

    MessageBox("Error", "HTTP Status Code: " + String(li_statusCode))
End If

Hi Marina,

HTTP 500 error is usually an error from the Server side. Refer to: (https://developer.mozilla.org/en-US/docs/Web/HTTP/Status/500)

After getting the HTTP 500 error, what can you see in "ls_response"? You can also use Fiddler to capture this HTTP request and analyze the HTTP response.

There is an HTTP 500 error case mentioned in https://community.appeon.com/index.php/articles-blogs/tutorials-articles/2-powerbuilder/236-call-soap-web-services-using-httpclient-object (Search "For example, we use Postman to verify it here."). It's caused by the wrong Content-Type. You can verify it.

You can use Fiddler to compare the HTTP requests between your original soap case and the new HttpClient case.

Regards, Logan

Question:

For example (old code VS new code)

//SoapConnection lsp_Cnn -- old code
HttpClient lsp_Cnn -- new code

customersupd p_customersupd  -- (customersupd - WS)

//lsp_Cnn = Create SoapConnection -- old code
lsp_Cnn = Create HttpClient -- new code


//lsp_Cnn.SetProxyServerOptions (ls_location) -- old code
li_rc = lsp_Cnn.SendRequest("GET", ls_location) -- new code - connects to the URL location

//ll_Ret = lsp_cnn.CreateInstance( p_customersupd, "customersupd") -- old code
//ll_Ret = lsp_cnn.GetContextService (  "customersupd" , p_customersupd ) -- tried this' but p_customersupd remains NULL -- what is the new code for this?

 

//luo_wsresult = p_customersupd.updatecustomer( auo_customerschema)  -- old code - calls specific function updatecustomer of customersupd - WS

-- what is the new code for this?

 

Thanks in advance

Marina
