我試圖使用XmlHttpRequest從JavaScript文件運行php腳本。但由於某些原因，我的代碼只是將字符串作爲字符串返回，而不是實際運行它。從javascript文件調用時，php將無法運行
如果我從全局URL單獨運行它，php運行得很好，但它不會從javascript文件運行，這意味着我的javascript請求出現問題了嗎？
我使用Apache和nodejs在Ubuntu上本地運行所有內容。我早前被引導到這個鏈接：PHP code is not being executed, instead code shows on the page，但是看起來Ubuntu沒有httpd.conf文件，而是使用apache2.conf。我不確定它們之間有什麼區別或如何在不破壞它的情況下如何處理它。另外，上面的鏈接只是暗示它是php的錯？但是當我通過全球網址訪問時，我的php文件運行得非常好。
下面是是應該調用PHP文件的JavaScript代碼片段：
function drawOutput(responseText) {
console.log(responseText);
}
function drawError(status) {
console.log('Error: ' + status);
}
// handles the response, adds the html
function getRequest(url, success, error) {
var req = false;
try{
// most browsers
req = new XMLHttpRequest();
} catch (e){
console.log("XML request failed.");
return false;
}
if (!req) return false;
if (typeof success != 'function') success = function() {};
if (typeof error!= 'function') error = function() {};
req.onreadystatechange = function(){
if(req.readyState == 4) {
return req.status === 200 ? success(req.responseText) : error(req.status);
}
}
req.open("GET", url, true);
req.send(null);
return req;
}
var urlString = '../tests/server_scripts/page_load.php' + encodeURIComponent('game_id') + '=0&' + encodeURIComponent('client_timestamp') + '=10';
//var urlString = "http://rpal.cs.cornell.edu/YH/public/tests/server_scripts/page_load.php?" + encodeURIComponent('game_id') + '=0&' + encodeURIComponent('client_timestamp') + '=10';
//var urlString = 'http://localhost/YH/WebHanabi/public/tests/server_scripts/page_load.php&' + encodeURIComponent('game_id') + '=0&' + encodeURIComponent('client_timestamp') + '=10';
console.log(urlString);
var urlRequest = getRequest(
urlString, // URL for the PHP file
drawOutput, // handle successful request
drawError // handle error
);
編輯： 這是我的HTML：

這裏就是我想從運行PHP文件javascript：
<?php
header('Access-Control-Allow-Origin: *');
include("connection.php");
//specific
if(!isset($_GET["game_id"]) || !isset($_GET["client_timestamp"])){
print(json_encode(array("error_code" => "1", "message" => "missing game_id or client_timestamp")));
return;
}
$game_id = $_GET["game_id"];
$client_timestamp = $_GET["client_timestamp"];
if(!is_numeric($game_id) || !is_numeric($client_timestamp)){
print(json_encode(array("error_code" => "2", "message" => "game_id or client_timestamp malformed, integers only")));
return;
}
// jsonp
$jsonp = false;
if (isset($_GET["callback"])) {
$jsonp = true;
$jsonp_methodname = $_GET["callback"];
}
//insert new id
$user_id = isset($_GET["user_id"]) ? $_GET["user_id"] : generateRandomString(40);
if(!isset($_GET["user_id"])){
$st1 = $mysqli->prepare("INSERT INTO users (user_id, user_info) VALUES (?, ?)");
$user_info = isset($_GET["user_info"]) ? $_GET["user_info"] : "";
$st1->bind_param("ss", $user_id, $user_info);
$st1->execute();
}
$st = $mysqli->prepare("INSERT INTO player_pageload_log (user_id, server_timestamp, game_id, version_id, session_id, client_timestamp, host_domain, referrer_host, referrer_path) VALUES (?, ?, ?, ?, ?, ?, ?, ?, ?)");
$server_timestamp = time();
$version_id = isset($_GET["version_id"]) ? $_GET["version_id"] : 1;
$session_id = isset($_GET["session_id"]) ? $_GET["session_id"] : generateRandomString(36);
$host_domain = $_SERVER["HTTP_HOST"];
$referrer_host = $_SERVER["HTTP_USER_AGENT"];
$referrer_ip = $_SERVER["REMOTE_ADDR"];
$st->bind_param('siiisisss', $user_id, $server_timestamp, $game_id, $version_id, $session_id, $client_timestamp, $host_domain, $referrer_host, $referrer_ip);
$st->execute();
// Return response as either json or jsonp if method wrapper (as GET param 'callback') was specified.
$json_response = json_encode(array("error_code" => "0", "message" => "success", "user_id" => $user_id, "session_id" => $session_id));
if ($jsonp) {
print($jsonp_methodname . '(' . $json_response . ');');
}
else {
print($json_response);
}

您是從文件系統還是從服務器運行腳本，它是像'file：/// var/www/html/index.html'這樣的東西嗎？ –
，如果它不是'file：///'，但確實是'http：// localhost'，那麼看看你的js控制檯。 –
看看你以前的另一個問題http://stackoverflow.com/q/43421794/1415724你說你試過// InsertAbsolutePathHere/tests/my_file.php和file：/// InsertAbsolutePathHere/tests/my_file。 php' - 問題是清楚的，儘管你所有的過去的問題。 –
