HTTP Response Inspection

See more HTTP Examples

Demonstrates how to inspect the HTTP response, including the status code, status text, and response headers, for Chilkat methods that don't use an HttpResponse object. B4X

Dim http As ChilkatHttp
http.Initialize("http")

'  Returns the contents of the response body.
Dim jsonText As String = http.QuickGetStr("https://chilkatsoft.com/helloWorld.json")

'  Examine the response status code.
Log("response status code: " & http.LastStatus)

'  Examine the response status text
Log("response status text: " & http.LastStatusText)

'  Examine the full response header.
Log("response header:")
Log(http.LastResponseHeader)
Log("----")

'  Examine the response content-type
Log("LastContentType = " & http.LastContentType)

'  Examine the response last-mod date
Log("LastModDate = " & http.LastModDate)

'  Load the response header into a Chilkat MIME object to access its fields individually.
Dim mime As ChilkatMime
mime.Initialize
mime.LoadMime(http.LastResponseHeader)

Dim numHeaders As Int = mime.NumHeaderFields
Dim i As Int = 0
Log("---- MIME Headers ----")
Do While i < numHeaders
    Log("name:  " & mime.GetHeaderFieldName(i))
    Log("value: " & mime.GetHeaderFieldValue(i))
    i = i + 1
Loop
Log("----")

'  Get a header field value by name:
Log("ETag: " & mime.GetHeaderField("ETag"))
