Hi,
Unlike many here, I am relatively new to Google APIs, so I beg your
patience.
I am currently tasked with implementing a mapping system which will use
Fusion Tables. I have successfully uploaded tables using the Google UI, and
written my code to display the map and the FusionTables layer. However, I
now need to be able to update the tables programmatically rather than
through the Google UI. Clearly this means being able to get my application
to log in and upload the data, but I am currently not having any success
with the login process.
I am sending a POST request to the Google accounts service using VB as
follows (stripped down to its basics)...
Dim webRequest As WebRequest = webRequest.Create("
https://www.google.com/accounts/ClientLogin";)
webRequest.Method = "POST"
webRequest.ContentType = "application/x-www-form-urlencoded"
Dim requestStream As Stream = webRequest.GetRequestStream()
Dim streamWriter As StreamWriter = New StreamWriter(requestStream)
streamWriter.Write(Server.UrlEncode("
accountType=GOOGLE&Email=<MyEmail>&Passwd=<MyPassword>&service=fusiontables&source=<MyApplicationName>
"))
streamWriter.Flush()
streamWriter.Close()
requestStream.Close()
' Get the response from the remote server...
Dim webResponse As WebResponse = webRequest.GetResponse()
.......
Where <MyEmal> is my Google account email address, <MyPassword> is my Google
account password, and <MyApplicationName> is something I made up to
represent the application.
The GetResponse() is throwing a 403 "Forbidden" *exception* whether I
include the content or not. I did expect from the documentation that I
should get a response with an error message and a "url giving more
information".
My questions are...
1) Am I correct in thinking that I should be authenticating using my Google
account credentials, or are special credentials required for using Fusion
Tables?
2) If special credentials are required, how do I go about obtaining these?
3) If sepecial credentials are not required, can anyone point out any
problems with the above code? I have redirected the url to one of our own
sites and the posted content certainly looks exactly as it should!
Many thanks in advance, David.
