Looped HTTP Requests

Hssarth

Before anyone asks, this isn't in the SQL forum because the database calls work just fine.

 $i = 0;
	while ($i < $num){


	$url=mysql_result($result,$i,"userUUID");
	$string=$_POST["name"]."~".$_POST["msg"];

	$r = new HttpRequest($url,HttpRequest::METH_POST);


	$r ->setContentType('text/xml');


	$r ->setRawPostData($string);
print("Num: ".$i);

	$r->send();



	$i++;

}

The loop seems to crash after completing a send. The print statement in there is so I can tell how many iterations it gets though, and never gets through until 28 seconds or so after it sends once. Any ideas?

dagon

do you need to reinitialise HttpRequest on every loop?

Hssarth

Honestly, I'm quite new to PHP. I may not need to. However, it won't even get as far as $i++.

dagon

drop the loop (for now) see if HttpRequest has any error return

Hssarth

I can't get anything out of it. It also can't even complete the first iteration. The problem isn't the loop, but the send() method. If I put a print or echo between it and $i++, it won't execute.

dagon

what's the send() method?

Hssarth

$r->send();

That's what sends the HTTP Request....

dagon

not being psychic, how about the actual function.

Hssarth

That's the problem. I can't get any result out of send(). It crashes the script and prevents anything else from executing after it sends the message.

I haven't used this class myself yet (there are other approaches possible); but from what I can see in the manual you're supposed to check what the server sends back in response to what you sent.

Hssarth

Like I said, I can't get anything out of it. If I were to use...

$result=$r->send();

It can't get far enough to do anything with $result. As soon as it sends the message, the file crashes and sends the above print statement 28 seconds later. Now.. If there's a better way of doing this, I'm all ears. >.>

Weedpacket

28 seconds... what happens when it "seems to crash"? Any error messages? Possibly the server you're posting to is timing out (I'd expect it to throw an exception in that situation)?

A different way of doing this (I wouldn't necessarily say better) is through [man]fopen[/man]: you can use [man]context[/man] options to set the method and headers; the XML goes in the content parameter.

Hssarth

There are no error messages. If anything, it just returns blank. The file in question is -only- triggered via another HTTP Request. If it's throwing an exception, I can't do anything with it. A try/catch statement still won't get past send().

Hssarth

Okay, I switched around to read

 $i = 0;
	while ($i < $num){


	$url=mysql_result($result,$i,"userUUID");
	$string=$_POST["name"]."~".$_POST["msg"];



	$ch = curl_init();
	curl_setopt($ch, CURLOPT_URL, $url);
	curl_setopt($ch,CURLOPT_RETURNTRANSFER,1);
curl_setopt($ch, CURLOPT_POST, 1 );
curl_setopt($ch, CURLOPT_POSTFIELDS,     $string );

print("Num: ".$i);




$result = curl_exec ($ch);
curl_close ($ch);







	$i++;

}

Same issue, unfortunately. If I say print("Result: ".$result); right after it's defined, it won't give me anything as it can't get past the curl_exec line. The function "works" and sends the data once, like the send() call.

dagon

i would be willing to try it on some of my servers if you can provide a test script (hard code the var's)

Hssarth

      <?php



//$num = mysql_numrows($result);
            $num = 5; // Just to see if you can get past the first iteration.
print("Rows: ".$num);

    $i = 0;
while ($i < $num){


	//$url=mysql_result($result,$i,"userUUID");
                            $url="http://foobar.com";

	//$string=$_POST["name"]."~".$_POST["msg"];
                            $string="This is a test.";



	$ch = curl_init();
	curl_setopt($ch, CURLOPT_URL, $url);
	curl_setopt($ch,CURLOPT_RETURNTRANSFER,1);
curl_setopt($ch, CURLOPT_POST, 1 );
curl_setopt($ch, CURLOPT_POSTFIELDS,     $string );

print("Num: ".$i);




$result = curl_exec ($ch);
curl_close ($ch);







	$i++;

}


  ?>

If you can get the looped print statement to show you've successfully entered the second iteration, you've done it.

Hssarth

I should have commented this in.. $url needs to be something able to recieve HTTP responses (HTTPRequest POST). It's about the only way you'll be able to tell what's going on. >.>

Rows: 5
Num: 0
Num: 1
Num: 2
Num: 3
Num: 4

google.com

there are some potential php set up issues, where\how is this installed?

Hssarth

O.o Did you modify any code? I can't get past Num: 0.

This is installed on a server I run locally.

dagon

locally, your machine? configured the firewall?
