php中ajax请求

来源：互联网发布：网络信息安全实施方案编辑：程序博客网时间：2024/05/17 04:06

php中ajax请求的时候，网上一般都是如下这个样子：

<html><head><script>function showHint(str){    if (str.length==0)    {         document.getElementById("txtHint").innerHTML="";        return;    }    if (window.XMLHttpRequest)    {        // IE7+, Firefox, Chrome, Opera, Safari 浏览器执行的代码        xmlhttp=new XMLHttpRequest();    }    else    {            //IE6, IE5 浏览器执行的代码        xmlhttp=new ActiveXObject("Microsoft.XMLHTTP");    }    xmlhttp.onreadystatechange=function()    {        if (xmlhttp.readyState==4 && xmlhttp.status==200)        {            document.getElementById("txtHint").innerHTML=xmlhttp.responseText;        }    }    xmlhttp.open("GET","gethint.php?q="+str,true);    xmlhttp.send();}</script></head><body><p><b>在输入框中输入一个姓名:</b></p><form> 姓名: <input type="text" onkeyup="showHint(this.value)"></form><p>返回值: <span id="txtHint"></span></p></body></html>

服务端：

<?php// 将姓名填充到数组中$a[]="Anna";$a[]="Brittany";$a[]="Cinderella";$a[]="Diana";$a[]="Eva";$a[]="Fiona";$a[]="Gunda";$a[]="Hege";$a[]="Inga";$a[]="Johanna";$a[]="Kitty";$a[]="Linda";$a[]="Nina";$a[]="Ophelia";$a[]="Petunia";$a[]="Amanda";$a[]="Raquel";$a[]="Cindy";$a[]="Doris";$a[]="Eve";$a[]="Evita";$a[]="Sunniva";$a[]="Tove";$a[]="Unni";$a[]="Violet";$a[]="Liza";$a[]="Elizabeth";$a[]="Ellen";$a[]="Wenche";$a[]="Vicky";//从请求URL地址中获取 q 参数$q=$_GET["q"];//查找是否由匹配值， 如果 q>0if (strlen($q) > 0){    $hint="";    for($i=0; $i<count($a); $i++)    {        if (strtolower($q)==strtolower(substr($a[$i],0,strlen($q))))        {            if ($hint=="")            {                $hint=$a[$i];            }            else            {                $hint=$hint." , ".$a[$i];            }        }    }}// 如果没有匹配值设置输出为 "no suggestion" if ($hint == ""){    $response="no suggestion";}else{    $response=$hint;}//输出返回值echo $response;?>

网上都是这样，原生的ajax请求。但是php有自己封装的ajax请求。操作也比较方便。现在我附录一个比较全面的demo：

<?php    $billingUrl = 'http://localhost/smart/billing.html';    $amount = $_REQUEST['amount'];    if($amount != 0){        $result = "";        $email = $_REQUEST['email'];        $company = $_REQUEST['company'];        $date = $_REQUEST['date'];        $billingAddress = $_REQUEST['billingAddress_name'].                        " ".$_REQUEST['billingAddress_address_line1'].                        " ".$_REQUEST['billingAddress_postal_code'].                         " ".$_REQUEST['billingAddress_city'].                        " ".$_REQUEST['billingAddress_country'].                        " ".$_REQUEST['billingAddress_province'];        $shippingAddress = $_REQUEST['shippingAddress_name']." ".                            $_REQUEST['shippingAddress_address_line1']." ".                            $_REQUEST['shippingAddress_postal_code']." ".                            $_REQUEST['shippingAddress_city']." ".                            $_REQUEST['shippingAddress_country']." ".                            $_REQUEST['shippingAddress_province'];        $currency = $_REQUEST['currency'];        $tax = $_REQUEST['tax'];        $itemDescription = $_REQUEST['itemDescription'];        //$comment = $_REQUEST['comment'];                        $code = $_REQUEST['cardInfo_code'];        $cardInfo_name = $_REQUEST['cardInfo_name'];        $billingStr = '{"email":"'. $email .            '","company":"'. $company .            '","date":"'. $date .'","code":"'. $code .            '","transId":"0","billingAddress":"'. $billingAddress .

'","itemDescription":"'. $itemDescription .            '","comment":"","paymentStatus":"false"}';        $insertBillingReturn = json_decode(insertBillingTable('http://localhost:3000/billing',$billingStr));        if($insertBillingReturn -> success == 1){            $id = $insertBillingReturn -> id;            //$paymentStr = '{"payment_method":"token","order_number":"MyOrderId000011223344","amount":"' . $amount .            //            '","token":{"code":"' . $code .             //            '","name":"' . $cardInfo_name . '","complete":true}}';              //$beanstreamReturn = json_decode(beanstreamPayment('https://www.beanstream.com/api/v1/payments', $paymentStr));                                //if($beanstreamReturn -> code != null){            //    echo "<script>alert('".$beanstreamReturn -> message."');location.href='".$billingUrl."';</script>";            //    exit;            //}            //else{            //    $transId = $beanstreamReturn -> id;            //    $str = '{"id":"'. $id .'","transId":"'. $transId .'","paymentStatus":"true"}';            //    $updateBillingReturn = json_decode(updateBillingTable('http://localhost:3000/billing',$str));            //    if($updateBillingReturn -> success == 1){                    echo "<script>alert('success');location.href='".$billingUrl."';</script>";                    exit;            //    }            //    else{            //        echo "<script>alert('".$updateBillingReturn -> error."');location.href='".$billingUrl."';</script>";            //        exit;            //    }            //}        }        else{            echo "<script>alert('".$insertBillingReturn -> error."');location.href='".$billingUrl."';</script>";            exit;        }    }    else{        echo "<script>alert('The amount is 0.');location.href='".$billingUrl."';</script>";        exit;    }    function beanstreamPayment($url, $post_data) {        $options = array(            'http' => array(              'method' => 'POST',              'header' => array(              'Content-type:application/json',              'Authorization:Passcode MzAwMjAwNTc4OjRCYUQ4MkQ5MTk3YjRjYzRiNzBhMjIxOTExZUU5Zjcw'            ),              'content' => $post_data,              'timeout' => 15 * 60           )          );          $context = stream_context_create($options);          $result = file_get_contents($url, false, $context);                  return $result;      }    function insertBillingTable($url, $post_data) {        $options = array(            'http' => array(              'method' => 'POST',              'header' => 'Content-type:application/json',            'content' => $post_data,              'timeout' => 15 * 60           )          );          $context = stream_context_create($options);        $result = file_get_contents($url, false, $context);                  return $result;      }     function updateBillingTable($url, $post_data) {        $options = array(            'http' => array(              'method' => 'POST',              'header' => 'Content-type:application/json',            'content' => $post_data,              'timeout' => 15 * 60           )          );          $context = stream_context_create($options);          $result = file_get_contents($url, false, $context);                  return $result;      }?>

下面是我自己更改出来适用自己的ajax，完整代码如上。

$alipayStr = '{"out_trade_no":"'. $out_trade_no .'","trade_no":"'. $trade_no .'","trade_status":"'. $trade_status .'","subject":"'. $subject .'","total_amount":"'. $total_amount .'","body":"'. $body .'"}';$insertBillingReturn = json_decode(insertAlipayTable('http://localhost:3389/alipayZhifubao',$alipayStr));if($insertBillingReturn -> success == 1) {  }else{}function insertAlipayTable($url, $post_data) {$options = array(  'http' => array(    'method' => 'POST',    'header' => 'Content-type:application/json',  'content' => $post_data,    'timeout' => 15 * 60 )  );  $context = stream_context_create($options);$result = file_get_contents($url, false, $context);  return $result;  }
