telnet send a http request
I am using telnet to send a http request , like this:
telnet> open 192.168.4.135 8087
Trying 192.168.4.135...
Connected to 192.168.4.135.
Escape character is '^]'.
POST /rpc/ HTTP/1.1
HOST:192.168.4.135:8087
Content-length:18
Content-type:application/x-http-form-urlencoded
action=loadrsctype
HTTP/1.1 200 OK
Date: Thu, 17 May 2012 03:52:53 GMT
Content-Length: 45
Content-Type: text/html; charset=ISO-8859-1
return=fail&error=Configuration doesn't existHTTP/1.1 400 Bad Request
Content-Type: text/html
Connection: close
Date: Thu, 17 May 2012 03:52:53 GMT
Content-Length: 94
<HTML><HEAD>
<TITLE>400 Bad Request</TITLE>
</HEAD><BODY>
<H1>Bad Request</H1>
</BODY></HTML>
Connection closed by foreign host.
the response code is 200 , but why there is a paragraph like this :
HTTP/1.1 400 Bad Request
Content-Type: text/html
Connection: close
Date: Thu, 17 May 2012 03:52:53 GMT
Content-Length: 94
<HTML><HEAD>
<TITLE>400 Bad Request</TITLE>
</HEAD><BODY>
<H1>Bad Request</H1>
</BODY></HTML>
This is the output of the server or telnet itself ? How to avoid to show this ?
--update-- When i change "HTTP/1.1" to "http/1.1", i get the right response. Now i wonder wheather this is requirement of protocol or related with the implementation of the server?
In HTTP 1.1 , all connections are considered persistent unless declared otherwise.
Then... I think the server is receiving some spurious newline char and reply with a Bad Request .
If you use http/1.1 instead of HTTP/1.1 could make fallback the version to the version 1.0 that's not persistent by default and after the 200 OK response it drops the connection.
The code at the URL you are accessing is printing some text:
return=fail&error=Configuration doesn't exist
But then your code continues on to print a HTTP 400 error. Probably you forgot to abort after printing the response, and so your code goes on to print the HTTP 400 as well.
Try replacing & with & .
