[英]Ajax POST is sending empty parameters
更新-我已经解决了问题
我发现了问题,它是php.ini
中post_max_size
的属性,该属性设置为8MB。 将其更改为20MB后,一切正常。 感谢您指出代码中的一些语法问题。
原始帖子
我的代码在页面的body标签中:
<script type = "text/javascript" >
$(document).ready(function() {
var scriptPath = "<?php echo $jobJSPath[0]; ?>";
if (scriptPath != "") {
var hasInput = "<?php echo $hasInput; ?>";
var jobExecIp = "<?php echo $jobtekerIP; ?>";
var sentToExec = "<?php echo $sentToExececution;?>";
var hasOutput = <?php echo json_encode($allOutputVarName);?>;
$.getScript(scriptPath, function(data, textStatus, jqxhr) {
var jobBatchID = "<?php echo $jobsArray[0];?>";
var jobID = "<?php echo $jobsArray[1];?>";
var jobName = "<?php echo $jobsArray[2];?>";
// execute a function inside the script has no input parameter
if (typeof hasInput !== 'undefined' && hasInput === 'no'){
// execute a function inside the script with no input parameter
var returnVar = <?php echo $newJobName; ?>;
}
// execute a function inside the script has input parameter
if (typeof hasInput !== 'undefined' && hasInput === 'yes'){
var vars = [];
// create an array of all the paths of the input variables
var arrayFromPHP = <?php echo json_encode($newAllInputVarPath);?>;
for (var i = 0; i < <?php echo sizeof($newAllInputVarPath);?>; i++) {
vars.push(JSON.parse($.ajax({type: "GET", url: arrayFromPHP[i], async: false, cache: false}).responseText));
}
// execute a function inside the script with multiple input parameter
var returnVar = <?php echo $jobsArray[2]; ?>.apply(this, vars);
}
// get the execution status
var execMessage = textStatus;
// for the jobs without any return parameter
if (hasOutput.length = 1 && hasOutput[0] === "NULL") {
var result = "No parameters are being returned";
$.ajax({
url: 'executedJobs.php',
type: 'POST',
data: {results : result, job_batch_id : jobBatchID, job_id : jobID, job_name : jobName, sentToExec : sentToExec, jobExecIp : jobExecIp, execMessage : execMessage},
cache: false
});
} else { // for the jobs with any return parameter
if (typeof returnVar != 'undefined' ) {
// this parameter is going to be posted to another page
var result = [];
var numOfOutputVar = <?php echo $jobsArray[4]; ?>;
if (Object.prototype.toString.call(returnVar) === '[object Array]') {
var countIndex = 0;
var countValue = 0;
var allValuesNoArray = false;
// check if all the returnVar values are not [object Array]
$.each(returnVar, function(index, value) {
console.log(Object.prototype.toString.call(value));
countIndex = countIndex + 1;
// check if value is not an [object Array] not an '[object String]'
if (Object.prototype.toString.call(value) !== '[object Array]' && Object.prototype.toString.call(value) !== '[object String]'){
countValue = countValue + 1;
}
});
// if all returnVar values are not [object Array] then true
if (countIndex === countValue) {
allValuesNoArray = true;
}
// if at least one returnVar value is an [object Array] then do
if (allValuesNoArray === false ) {
// if the job has more than one return variable
if (numOfOutputVar > 1) {
$.each(returnVar, function(index, value) {
result.push(JSON.stringify(value));
})
} else { // if the job has only one return variable
var allRetVarToOne = [];
$.each(returnVar, function(index, value) {
allRetVarToOne.push(value);
})
result.push(JSON.stringify(allRetVarToOne));
}
} else { // if all returnVar values are not [object Array] then do
console.log(numOfOutputVar);
// if the job has more than one return variable
if (numOfOutputVar > 1) {
$.each(returnVar, function(index, value) {
result.push(JSON.stringify(value));
})
} else { // if the job has only one return variable
result.push(JSON.stringify(returnVar));
}
}
} else {
result.push(JSON.stringify(returnVar));
}
// executes the POST if everything is ok
$.ajax({
url: 'executedJobs.php',
type: 'POST',
data: {results : result, job_batch_id : jobBatchID, job_id : jobID, job_name : jobName, sentToExec : sentToExec, jobExecIp : jobExecIp, execMessage : execMessage},
cache: false
});
} else { // executes this POST if the job execution was not successful, with no reason
var execMessage = "An unknown falure has accourd while executing, will be executed once more"
$.ajax({
type: 'POST',
data: {results : result, job_batch_id : jobBatchID, job_id : jobID, job_name : jobName, sentToExec : sentToExec, jobExecIp : jobExecIp, execMessage : execMessage},
cache: false,
url: 'executedJobs.php'
});
}
}
}).fail(function(jqxhr, settings, exception) { // executes if the getScript(scriptPath, function(data, textStatus, jqxhr) {}) faild
var execMessage = exception.message;
var result = undefined;
var jobBatchID = "<?php echo $jobsArray[0];?>";
var jobID = "<?php echo $jobsArray[1];?>";
var jobName = "<?php echo $jobsArray[2];?>";
var sentToExec = "<?php echo $sentToExececution;?>";
$.ajax({
type: 'POST',
data: {results : result, job_batch_id : jobBatchID, job_id : jobID, job_name : jobName, sentToExec: sentToExec, jobExecIp : jobExecIp, execMessage : execMessage},
cache: false,
url: 'executedJobs.php'
});
});
}
});
</script>
问题是,如果我使用var returnVar = <?php echo $newJobName; ?>
执行的函数,我的注释下的帖子“如果一切正常,则执行POST”将发送空参数var returnVar = <?php echo $newJobName; ?>
var returnVar = <?php echo $newJobName; ?>
或var returnVar = <?php echo $jobsArray[2]; ?>.apply(this, vars);
returnVar = <?php echo $jobsArray[2]; ?>.apply(this, vars);
var maxNum = 500000;
和var arrayMaxSize = 500000;
。 当我看在控制台中的POST的参数窗口下executedJobs.php
,我正确的结果也只是没有的课程,而不是executedJobs.php页面本身的视图窗口上。 这就是var returnVar正在调用的函数
function job1() {
var notSortNumArray = [];
var notSorted1 = [];
var notSorted2 = [];
var maxNum = 500000;
var arrayMaxSize = 500000;
var minNum = 1;
// create an array with arrayMaxSize random nmber between minNum and maxNum
for (var x = 0; x < arrayMaxSize; x++) {
notSortNumArray.push(Math.floor(Math.random() * (maxNum - minNum)) + minNum);
}
// The notSorted1 is from possition 0 untill random between 0 and arrayMaxSize
notSorted1 = notSortNumArray.slice(0, Math.floor(Math.random() * notSortNumArray.length));
// The notSorted2 is from where the notSorted1 ends untill the last number form the notSortNumArray
notSorted2 = notSortNumArray.slice(notSorted1.length, notSortNumArray.length);
// job dependencies
var nextJob = "job2, job3";
var prevJob = "null";
// results
return [ notSortNumArray, arrayMaxSize, notSorted1, notSorted2 ];
}
有趣的是,对于var maxNum = 250000;
和var arrayMaxSize = 250000
一切都运行完美,所有的结果都被发送到executedJobs.php
页了解更多。
再次,我希望有人能帮助我解决这个问题,因为我不知道为什么它不能用于更大数量的var maxNum
和var arrayMaxSize
参数,结果在那里,它们已经被发送到了var arrayMaxSize
页面但是什么都没有结束。
我知道这是很多代码,但是我希望有人可以帮助我解决这个问题,因为我不知道为什么它不起作用。
行中没有分号:
var scriptPath = "<?php echo $jobJSPath[0]; ?>"
var execMessage = "An unknown falure has accourd while executing, will be executed once more"
排队 :
var hasOutput = <?php echo json_encode($allOutputVarName);?>;
您应该将其更改为:
var hasOutput = JSON.parse("<?php echo json_encode($allOutputVarName);?>");
