Error while using the HTTP adapter 1

[thisismondweep]

Hi,

I am using the sample map httppost to post a request to a webserver and store its response. The map rule says:-

=GET("HTTP",
"-URL

http://www.google.co.uk/search?hl=en

-METHOD POST -TV","&q="+searchtext: FieldValue+"&meta="
)

However, the trace file says that it could not get the result, as shown below:-

"Server host is '

http://www.google.co.uk'.

WSAHostData: No host data available for '

http://www.google.co.uk'.

(host has no data record).
No connection."

The complete trace file is:-

I would appreciate any help to understand how to connect to the webserver and retrieve information from it.

your server can't resolve

http://www.google.co.uk

try doing a "ping

http://www.google.co.uk"

or "nslookup

http://www.google.co.uk"

to confirm.

Either use an IP address, add an entry to the hosts table or set up your DNS server.

(does your server have a connection to the Internet, or do you go through a proxy server?)

Olly,

Thank you for your response. I could run the sample map httpget.mmc and get a form from an external website. I do have access to the internet and also could connect to google.co.uk.

Yes, I connect to the web using a proxy server.I will try with the ip address though I am not sure of what you requested about setting up a DNS server. Is it something to do in DSTX?

Cheers,
Mondweep.

Olly,

You are correct- I cannot ping google.co.uk! This is strange though. I thinkthis is because-as you have rightly indicated- I access the internet through a proxy. When I do a nslookup on google.co.uk, I am provided the local server(I think the proxy server DNS and the ipaddress).

However, from Internet Explorer, i can access the website google.co.uk. What should be the way that I can access it fromwithin the TX map?

Cheers,
Mondweep.

Hi,

I tried to connect using the ipaddress of google.co.uk. However,this time, I encountered the error:-

WSAConnect: Connection refused.

I understand that the proxy server blocked the attempt to connect to the address. What way can I get around this?

Cheers,
Mondweep.

Specify the proxy server in the adapter string:
-PROXY

http://user:pass@host:port

see the documentation for more details.

Hello,

I used the command as
= GET("HTTP",
"-URL

http://www.google.co.uk/search?hl=en&q=Assam&meta

-METHOD POST -PROXY

http://user:pass@proxy:80

-TV")

It did connect to the internet and the trace showed me that the POST was

http://www.google.co.uk/search?hl=en&q=Assam&meta HTTP/1.1

This string, in Internet Explorer, produces the google search results. However, when I run the same through the map,I get a message from google which says:
Google Error
Not Implemented
The server is unable to process your request.

I am not sure why Google will respond to the same query, in one way, when executed through Internet Explorer and in another way, when performed through the DSTX map. I think I am missing something when executing it from my map; but aint quite sure what it is!

Any comments would be gratefully received.

Cheers,
Mondweep.

Yahoo!

It finally worked

The problem was that I was using -TYPE POST. It worked with -GET as shown below:-

= GET("HTTP",
"-URL

http://www.google.co.uk/search?hl=en&q=Assam&meta

-METHOD POST -PROXY

http://user:pass@proxy:80

-TV")

Olly,

Thank you very much for pointing me in the correct direction!

Cheers,
Mondweep.
