Examples
This example requests information in a loop:
Integer i, li_PackCount, li_rc
Blob lblb_photo, lblb_NextData
HttpClient lnv_HttpClient
lnv_HttpClient = Create HttpClient
// Read photo to lblb_photo and calculate li_PackCount
//...
lnv_HttpClient.SetRequestHeader("Content-Type", "multipart/form-data; boundary--------------------------359875084413580694217125")
// Construct a POST request
lnv_HttpClient.SetRequestHeader("Content-Length", string(len(lblb_photo)))
// Start posting data and request information
if lnv_HttpClient.PostDataStart("https://demo.appeon.com/PB/webapi_client/employee/102/photo") = 1 then
for i = 1 to li_PackCount
lblb_NextData = blobmid(lblb_photo, (i - 1) * 1024 + 1, 1024)
li_rc = lnv_HttpClient.PostData(lblb_NextData, 1024)
if li_rc <> 1 then exit
next
end if
if li_rc = 1 then
li_rc = lnv_HttpClient.PostDataEnd()
end if
