PHP如何调用Delphi开发的DataSnap/Restful接口服务

1、通用接口函数调用文件：testRestful.php

<?php

header("Content-Type:text/html;charset=utf-8");

<?php

//数组转换成以'/'分隔的字符串

function http_build_query_delphi($arr)

{

//$arr = array('url'=>'http://www.jb51.net','name'=>'脚本之家','str'=>'PHP教程');

$result = '';

//foreach($arr as $key=>$value){

foreach($arr as $value){

$result .= '/'.$value;

}

if (strlen($result)>0)

$result = substr($result,1); //删除第一个"/"字符

return $result;

}

/**

* [http 调用接口函数]

* @Date 2016-07-11

* @Author GeorgeHao

* @param string $url [接口地址]

* @param array $params [数组]

* @param string $method [GET\POST\DELETE\PUT]

* @param array $header [HTTP头信息]

* @param integer $timeout [超时时间]

* @return [type] [接口返回数据]

function http($func, $params, $method = 'GET', $header = array(), $timeout = 5)

{

define('_SRV','http://localhost:8019/peci/rest/TServerMethods/'); //定义了一个常量，应从配置文件中读取

define('_KEY','91F11212729292F2136DADED3656B6CECECECD3145474855B6'); //应从配置文件中读取

$params["KeyNumber"] = _KEY;//增加一个Key键值和元素

$url = _SRV . $func;

// POST 提交方式的传入 $set_params 必须是字符串形式

$opts = array(

CURLOPT_TIMEOUT => $timeout,

CURLOPT_RETURNTRANSFER => 1,

CURLOPT_SSL_VERIFYPEER => false,

CURLOPT_SSL_VERIFYHOST => false,

CURLOPT_HTTPHEADER => $header

);

/* 根据请求类型设置特定参数 */

switch (strtoupper($method)) {

case 'GET':

//通常$url=http://localhost/netpay/rest/TServerMethod1/GetXQList?xq=1&room=10110105

//$opts[CURLOPT_URL] = $url . '?' . http_build_query($params);

$opts[CURLOPT_URL] = $url . '/' . http_build_query_delphi($params);

//Delphi生成的Restful服务接口函数调用时不是常见?x=值1&y=值2的方式，而是直接/值1/值2的方式，问号？也用/替代了。

//如：$url=http://localhost/netpay/rest/TServerMethod1/GetXQList/1/10110105

break;

case 'POST':

$params = http_build_query($params);

$opts[CURLOPT_URL] = $url;

$opts[CURLOPT_POST] = 1;

$opts[CURLOPT_POSTFIELDS] = $params;

break;

case 'DELETE':

$opts[CURLOPT_URL] = $url;

$opts[CURLOPT_HTTPHEADER] = array("X-HTTP-Method-Override: DELETE");

$opts[CURLOPT_CUSTOMREQUEST] = 'DELETE';

$opts[CURLOPT_POSTFIELDS] = $params;

break;

case 'PUT':

$opts[CURLOPT_URL] = $url;

$opts[CURLOPT_POST] = 0;

$opts[CURLOPT_CUSTOMREQUEST] = 'PUT';

$opts[CURLOPT_POSTFIELDS] = $params;

break;

default:

throw new Exception('不支持的请求方式！');

}

/* 初始化并执行curl请求 */

$ch = curl_init();

//如果网站需要安全验证，那么需要执行下面两条命令，否则就不需要。

curl_setopt($ch, CURLOPT_HTTPAUTH, CURLAUTH_BASIC);

curl_setopt($ch, CURLOPT_USERPWD, 'username:password');

curl_setopt_array($ch, $opts);

$data = curl_exec($ch);

$error = curl_error($ch);

curl_close($ch);

return $data;

}

2、测试文件：test.php

<?php require("testRestful.php") ?>

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Stict//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-

strict.dtd">

<head>

</head>

<body>

<?php

$func = "GetRoomInfo_ByRoom";

echo "调用接口方法：" . $func . "(xiaoqu_id,room,KeyNumber)，结果如下：<hr>";

$params = array("xiaoqu_id" => "1", "room" => "10110105");

$result = http($func,$params);

if ($result === false)

echo "接口方法执行失败！";

else

echo "接口方法执行成功！返回结果为：<p>" . $result;

</body>

</html>

执行结果为：

该接口方法其实查询出了后台数据库中的如下记录：
