如何在jQuery和CasperJS中禁用超时

Question

My CasperJS script calls via jQuery an PHP script . Problem is, that the PHP script takes around 70 sec to excute, but somehow CasperJS or jQuery are canceling the request after around 30 sec and throw the error: Error: NETWORK_ERR: XMLHttpRequest Exception 101 .

Code to call the PHP script:

var result = casper.evaluate(function(){
    $.ajaxSetup({'async':false});
    var result = $.get('http://localhost/full.php', function() {} );
    return result;
});

I tried the following solutions:

// For CasperJS:
pageSettings: {
    timeout: 999999999
}

// For jQuery
$.ajaxSetup({'timeout':999999999});

Also I made sure that the executed PHP script is not the cause for the error (I made a test-script with all used functions, which only takes some seconds to execute. This works fine).

I read that jQuery has no timeout by default and that CasperJS throws an error, when a timeout occurs. But somehow it must be timeout error, because it always occurs after around 30 sec. (btw.. the PHP script uses set_time_limit(0); )

Thanks for any suggestions!

It's maybe the problem. Did you tried when you script when it takes 70 s ? Php has also a maximum execution time setting as said here . By default, it's 30 secs. Try to test in the same scenario.

Jsut for futures references, the default Jquery Ajax Timeout is 0 (technically it's undefined, but behaves as 0). This means no timeout in jQuery itself... You could specify one via $.ajax ({timeout: XXXX }) or $.ajaxSetup ({timeout: XXXX }) . The complete callback contains a string categorizing the status of the request ("success", "notmodified", "error", "timeout", "abort", or "parsererror").

There is also two timeouts in casperJs : timeout and steptimeout . There are also two callback ontimeout and on steptimout that are executed when script/step execution time exceeds these limits.
