    Help on cURL POST to remote page with javascript

    in PHP Coding Help

    Posted

    I updated my script but I still couldn't get the script to work. What I mean by this is that -

     

    when I use a browser to open the page and submit a fax, I would receive a confirmation email with a "confirmation link" in it. This is what I expect would happen if the script runs successfully. However, so far I have received no confirmation emails after using the script to submit my fax. Hence, I am still debugging the script to try to get it to work.

     

    Would someone please point me in the right direction please? Many thanks!

    Help on cURL POST to remote page with javascript

    in PHP Coding Help

    Posted

    I updated my script, polished out some useless lines of code, but I still couldn't get it to work. I did a watch on the packets sent by the webpage on normal use and I found that it had the following cookies.

     

    [output from Wireshark]

    Cookie: __utmz=88471047.1280829735.1.1.utmcsr=(direct)|utmccn=(direct)|utmcmd=(none); SSLB=1; SSID=AgB6lCkAAAAAJ-lXTKasAQEn6VdMCgApI2BMAAAAAAAAAAApI2BMAQAJAAAAygAAAAA; SSSC=1.G5501121823586233510.10.9.202; SSRT=KSNgTAE; ASP.NET_SessionId=hjscdafaki3d3m45fngdpmft; ProtusIPSolutions=4211124416.23808.0000; __utma=88471047.1550346862.1280829735.1281355449.1281368864.10; __utmc=88471047; __utmb=88471047.2.10.1281368864

     

    However, only the cookies " ASP.NET_SessionId" and "ProtusIPSolutions" are present when I access the page through cURL:

     

    [headers captured from cURL script, line 41-46 below in PHP script]

    Set-Cookie: ASP.NET_SessionId=lubhg1i52no5gz45pgwh4ly3; path=/; HttpOnly
Set-Cookie: ProtusIPSolutions=4211124416.23808.0000; expires=Mon, 09-Aug-2010 17:56:00 GMT; path=/

     

    I'm not sure if those cookies are the key to the my problem, though.

    Would someone please help me on the code and drop me a hint to point me in the right direction? Many thanks!

    Help on cURL POST to remote page with javascript

    in PHP Coding Help

    Posted

    Hi all,

     

    I am new here and I really thank God that I found this forum! I have read the materials here on working with cURL on javascript-form-submission pages. However, I can't to get my script to work. Can anybody here please help me out or drop me a hint on where to correct my script?

     

    ==Situation==

     

    My company utilizes http://www.myfax.com/free/ to send our company faxes. My task is to write a code that would submit files for faxes electronically.

     

    Note: The site also requires e-mail confirmation but I haven't get to that stage yet. I have run tests on submitting fax requests both by code and manually through the site, and have confirmed that the code doesn't work on the submission level because I managed to receive confirmation e-mails for manual submissions. Also, I tried my script with different staff email addresses because I figured out that it blocks only the same e-mail address from sending more than 2 faxes a day.

     

    <?php

//target page url
$strPage_url = 'www.myfax.com/free/';

//create array of data to be posted
$arrPost_data = array (
    'ctl00$MainSection$tbRecipientName' => 'I am recipient', //max length = 50
    'ctl00$MainSection$tbRecipientCompany' => 'I am recipient company', //max length = 50
    'ctl00$MainSection$tbRecipientFaxNumber' => '+1 (206) 202-8273', //recipient fax
    'ctl00$MainSection$ddlRecipientCountry' => html_entity_decode ('{"c":{"i":"2","n":"United States","t":"1","s":"US"},"m":{"i":"1","v":"+1 (###) ###-####","d":"","f":"","c":"","r":""}}'),
    'ctl00$MainSection$tbSenderName' => 'I am sender', //max length = 50
