New to sockets

[jmace]

I am trying to post a feed file to ebay from our site via a PHP script, but I am new to this stuff. I found some instructions here: http://pics.ebaystatic.com/aw/pics/pdf/us/file_exchange/File_Exchange_Advanced_Instructions.pdf

 

The most important part of that PDF is:

Sample HTTP Post Request

POST /path/to/upload/script HTTP/1.0

Connection: Keep-Alive

User-Agent: My Client App v1.0

Host:

https://bulksell.ebay.com/ws/eBayISAPI.dll?FileExchangeUpload

Content-type: multipart/form-data;

boundary=THIS_STRING_SEPARATES

Content-Length: 256

--THIS_STRING_SEPARATES

Content-Disposition: form-data; name="token"

12345678987654321

--THIS_STRING_SEPARATES

Content-Disposition: form-data; name="file";

filename="listings.csv"

Content-Type: text/csv

... contents of listings.csv ...

--THIS_STRING_SEPARATES

 

 

I tried to implement it using this code:

<?php

// GET THE FEED FILE
$options = array(
    CURLOPT_RETURNTRANSFER => true,
    CURLOPT_HEADER         => false, 
    CURLOPT_FOLLOWLOCATION => true, 
    CURLOPT_ENCODING       => "", 
    CURLOPT_USERAGENT      => "website", 
    CURLOPT_AUTOREFERER    => true,
    CURLOPT_CONNECTTIMEOUT => 120, 
    CURLOPT_TIMEOUT        => 120,
    CURLOPT_MAXREDIRS      => 10, 
    CURLOPT_SSL_VERIFYPEER => false,
);

$ch = curl_init('https://www.mysite.com/pull_feed.php');
curl_setopt_array( $ch, $options );
$contents = curl_exec( $ch );
curl_close( $ch );


//----------------------------------------------------//


//OPEN THE CONNECTION
$conn = fsockopen('https://bulksell.ebay.com/ws/eBayISAPI.dll?FileExchangeProgrammaticDownload', 80);

// START THE REQUEST
fputs($conn, "POST ".$_SERVER['PATH_INFO']." HTTP/1.0");
fputs($conn, "Connection: Keep-Alive");
fputs($conn, "User-Agent: My Client App v1.0");
fputs($conn, "Host:");
fputs($conn, "https://bulksell.ebay.com/ws/eBayISAPI.dll?FileExchangeUpload");
fputs($conn, "Content-type: multipart/form-data;");
fputs($conn, "boundary=THIS_STRING_SEPARATES");
fputs($conn, "Content-Length: ".strlen($contents));
fputs($conn, "--THIS_STRING_SEPARATES");
fputs($conn, "Content-Disposition: form-data; name=\"token\"");
fputs($conn, "MY_KEY_IS_HERE_000000000000000000000000");
fputs($conn, "--THIS_STRING_SEPARATES");
fputs($conn, "Content-Disposition: form-data; name=\"file\";");
fputs($conn, "filename=\"listings.csv\"");
fputs($conn, "Content-Type: text/csv");

// SEND THE FILE
fputs($conn, $contents);

// END THE REQUEST
fputs($conn, "--THIS_STRING_SEPARATES");

// GET THE RESULT
while(!feof($conn)) {
    echo fgets($conn, 128);
}

// CLOSE CONNECTION
fclose($conn);

?>

 

UPDATE: I accidently had error reporting off. Whoops. It is giving me this error:

Warning: fsockopen() [function.fsockopen]: unable to connect to https://bulksell.ebay.com/ws/eBayISAPI.dll?FileExchangeProgrammaticDownload:80 (Unable to find the socket transport "https" - did you forget to enable it when you configured PHP?) in C:\home\imafs\public_html\funad\ebay\send_feed.php on line 27

Followed by more errors resulting from that one.

https is served via port 443 not port 80. Looks like your php install might not be able to use https either.

Also, you open sockets to servers, not URLs.

Also, each request header needs to be followed by a \r\n, with an extra one at the very end of them (ie, between the headers and the request body).

Also, you aren't doing the request body correctly. Learn about multipart/form-data.

Also, considering how incorrect that stuff in the PDF is, I'm suspicious of the Host: header.

 

Learn about HTTP and basic networking before trying to implement anything. Really. Stop working with PHP right now and go read Wikipedia or get a book on it or something.

@Thorpe: Thanks for your reply. If my server can't use https, what alternative is there? Or what should I do?

 

@Requinix: Thanks for the insights and the tips. Where do you suggest I go to learn about all of this? I am on a time crunch and need to get this done as quick as I can, so a suggestion on what tutorials are best would be very helpful.

 

Thank you both again.

Based on your comments and some more poking around on the internet, I changed code to this:

<?php

// GET THE FEED FILE
$options = array(
    CURLOPT_RETURNTRANSFER => true,     // return web page
    CURLOPT_HEADER         => false,    // don't return headers
    CURLOPT_FOLLOWLOCATION => true,     // follow redirects
    CURLOPT_ENCODING       => "",       // handle all encodings
    CURLOPT_USERAGENT      => "website", // who am i
    CURLOPT_AUTOREFERER    => true,     // set referer on redirect
    CURLOPT_CONNECTTIMEOUT => 120,      // timeout on connect
    CURLOPT_TIMEOUT        => 120,      // timeout on response
    CURLOPT_MAXREDIRS      => 10,       // stop after 10 redirects
    CURLOPT_SSL_VERIFYPEER => false,
);

$ch = curl_init('https://www.mysite.com/pull_feed.php');
curl_setopt_array( $ch, $options );
$contents = curl_exec( $ch );
curl_close( $ch );


//----------------------------------------------------//


//OPEN THE CONNECTION
$conn = fsockopen('ssl://bulksell.ebay.com', 443);

// START THE REQUEST
fputs($conn, "POST ".$_SERVER['PHP_SELF']." HTTP/1.0\r\n");
fputs($conn, "Connection: Keep-Alive\r\n");
fputs($conn, "User-Agent: My Client App v1.0\r\n");
fputs($conn, "Host:\r\n");
fputs($conn, "https://bulksell.ebay.com/ws/eBayISAPI.dll?FileExchangeUpload\r\n");
fputs($conn, "Content-type: multipart/form-data;\r\n");
fputs($conn, "boundary=THIS_STRING_SEPARATES\r\n");
fputs($conn, "Content-Length: ".strlen($contents)."\r\n");
fputs($conn, "--THIS_STRING_SEPARATES\r\n");
fputs($conn, "Content-Disposition: form-data; name=\"token\"\r\n");
fputs($conn, "MY_SECRET_TOKEN\r\n");
fputs($conn, "--THIS_STRING_SEPARATES\r\n");
fputs($conn, "Content-Disposition: form-data; name=\"file\";\r\n");
fputs($conn, "filename=\"listings.csv\"\r\n");
fputs($conn, "Content-Type: text/csv\r\n\r\n");

// SEND THE FILE
fputs($conn, $contents."\r\n");

// END THE REQUEST
fputs($conn, "--THIS_STRING_SEPARATES\r\n");

// GET THE RESULT
while(!feof($conn)) {
    echo fgets($conn, 128);
}

// CLOSE CONNECTION
fclose($conn);

?>

 

Which is working a lot better, but now the response I get back is this:

HTTP/1.1 302 Moved Temporarily

Server: Apache-Coyote/1.1

Location: http://pages.ebay.com/messages/page_not_found.html?eBayErrorEventName=p4apjlp%60jk%60jtb9%3Fjf.rdkhvjk357-2010.11.24.10.12.13.161.MST

Date: Wed, 24 Nov 2010 17:12:13 GMT

Connection: close

 

I am guessing it is because I am on the wrong page (ie bulksell.ebay.com instead of https://bulksell.ebay.com/ws/eBayISAPI.dll?FileExchangeProgrammaticDownload)

 

What should I do now?

[jmace]

Well, I've made some progress, but still I still can't make it work.

 

Here is my code:

<?php

$key = "MY_KEY_HERE";

set_time_limit(0);

// GET THE FEED FILE
$options = array(
    CURLOPT_RETURNTRANSFER => true,     // return web page
    CURLOPT_HEADER         => false,    // don't return headers
    CURLOPT_FOLLOWLOCATION => true,     // follow redirects
    CURLOPT_ENCODING       => "",       // handle all encodings
    CURLOPT_USERAGENT      => "my app", // who am i
    CURLOPT_AUTOREFERER    => true,     // set referer on redirect
    CURLOPT_CONNECTTIMEOUT => 120,      // timeout on connect
    CURLOPT_TIMEOUT        => 120,      // timeout on response
    CURLOPT_MAXREDIRS      => 10,       // stop after 10 redirects
    CURLOPT_SSL_VERIFYPEER => false,
);

$ch = curl_init('https://mysite.com/pull_feed.php');
curl_setopt_array( $ch, $options );
$contents = curl_exec( $ch );
curl_close( $ch );

//----------------------------------------------------//

// CREATE THE REQUEST
$request = "POST /ws/eBayISAPI.dll?FileExchangeUpload HTTP/1.1\r\n";
$request .= "Connection: Keep-Alive\r\n";
$request .= "User-Agent: My Client App v1.0\r\n";
$request .= "Host: bulksell.ebay.com\r\n";
$request .= "https://bulksell.ebay.com/ws/eBayISAPI.dll?FileExchangeUpload\r\n";
$request .= "Content-type: multipart/form-data;\r\n";

$request .= $key."\r\n";
$request .= "--THIS_STRING_SEPARATES\r\n";
$request .= "Content-Disposition: form-data; name=\"file\";\r\n";
$request .= "filename=\"listings.csv\"\r\n";
$request .= "Content-Type: text/csv\r\n";
$request .= $contents."\r\n";
$request .= "--THIS_STRING_SEPARATES\r\n";

//OPEN THE CONNECTION
$conn = fsockopen('ssl://bulksell.ebay.com', 443);

// SEND THE REQUEST
fputs($conn, $request);

// GET THE RESULT
while(!feof($conn)) {
    echo fgets($conn, 128);
}

// CLOSE CONNECTION
fclose($conn);

?>

 

Here is the the request being sent:

POST /ws/eBayISAPI.dll?FileExchangeUpload HTTP/1.1
Connection: Keep-Alive
User-Agent: My Client App v1.0
Host: bulksell.ebay.com
https://bulksell.ebay.com/ws/eBayISAPI.dll?FileExchangeUpload

boundary=THIS_STRING_SEPARATES
Content-Length: 4102
--THIS_STRING_SEPARATES
Content-Disposition: form-data; name="token" 
MY_KEY_HERE
--THIS_STRING_SEPARATES
Content-Disposition: form-data; name="file";
filename="listings.csv"
Content-Type: text/csv
. . . THE FILE CONTENTS ARE HERE . . . 

--THIS_STRING_SEPARATES

 

The script take a long time to run, and then it finally gives me the following response from ebay:

ANY help would be appreciated. I'm really having a hard time with this one.
