Description
Sends the HTTP PATCH request to the server and then gets the content of the server response. It does not parse the HTTP response code and content of the server response.
It is NOT supported to use this method to process large data (20 MB or 100,000 data rows can be considered as large data based on our tests).
Applies to
Syntax
objectname.SendPatchRequest(string urlName, string data, ref string response)
|
Argument |
Description |
|---|---|
|
objectname |
The name of the RESTClient object from which you want to send the request. |
|
urlName |
A string value specifying the URL. |
|
data |
A string value specifying the data to send. If the user sets the encoding charset in the Content-Type request header, this function will encode the data with the specified charset; if charset is not specified, this function will encode the data in UTF-8 by default. |
|
response |
The content of the server response. If RESTClient failed to send request or server provides no response, the response value is an empty string. If the response value is compressed, it will be automatically decompressed. Gzip and Brotli compression formats are supported. If the server specified the Content-Type response header, and in which the encoding charset is specified, this function will encode the data with the specified charset; if charset is not specified, this function will encode the data in UTF-8 by default. |
Return value
Integer. Returns 1 if the function succeeds and a negative value if an error occurs. If any argument's value is null, the method returns null.
Example
The following example submits the new value of the current row in DataWindow to server and then returns the updated value.
RestClient lrc_P023
String ls_P023_Response
Integer li_P023_SendReturn,li_P023_GetTokenReturn
String ls_P023_Token,ls_P023_SendData

If dw_Data.GetRow() > 0 Then

//.....
//Exports the modified row to DataWindow JSON string
ls_P023_SendData = dw_Data.Exportjson( Primary!, dw_Data.GetRow(),dw_Data.GetRow(), True)
//Updates data via the following URL and returns the updated data row
li_P023_SendReturn=lrc_P023.SendPatchRequest("https://demo.appeon.com/PB/webapi_client/api/department/update/modelentry", ls_P023_SendData, ls_P023_Response)
If li_P023_SendReturn <> 1 Or lrc_P023.GetResponseStatusCode() <> 200 Then
//Checks if any error information and checks the responsebody: ls_P023_Response
End If
//Imports the returned data row to DataWindow
dw_Data.ImportRowFromJson(ls_P023_Response,0)
End If
Else
//Checks if any failure message
