javascript – Safari browser truncating POST parameters

Posted by: admin July 12, 2020 Leave a comment


My code works absolutely fine on other browsers than Safari 6.1.2 on Mac OS Lion.

Below is the ajax post that I use –

     type: 'POST',
     dataType: 'text/html',
     data:{"server":"mydomain.com", "user":"vijay", "passd":"[email protected]"},
     error: function(data) {
         alert("Failure - "+data);
     success: function(data) {
         console.log("Success - "+data);

Also for debug purpose, I have entered logs on my PHP server code

header('cache-control: no-cache');

function getRealPOST() {
    $pairs = explode("&", file_get_contents("php://input"));
    $vars = array();
    foreach ($pairs as $pair) {
        $nv = explode("=", $pair);
        $name = urldecode($nv[0]);
        $value = urldecode($nv[1]);
        $vars[$name] = $value;
    return $vars;

echo "-------";         
echo "-------";             


In Safari on console logs it shows something like –

-------array(2) {
  string(5) "vijay"
  string(4) "hig"

serverAdd] => mydomain.com
    [userName] => vijay
    [passwd] => hig

Any guess why only Safari is behaving in such way, even with iPad/iPhone and other OS where Safari is used as browser, I am facing this truncation problem. I have also read post where people are facing such issues, however, in those cases, they were having very large request, mine on other hand is just small request.

Any help?

How to&Answers:

I tested your code and I had an issue with the dataType: 'text/html' parameter of your request. Usually there is no need to specify it, jQuery is smart enough to understand the format the received outcome.

Removing the dataType parameter anyway I received the desired output:

I would also suggest you to use a proxy like Charles https://www.charlesproxy.com to view the real output obtained by the PHP script so you can figure out if you have a problem on javascript or server side.
