说明：php调用.net WebService，解决返回消息格式问题，比如数据库查询结果。本方案将.net DataTable序列化为JSON返回给php，php使用json_decode()解码JSON数据为数组。

一、环境

1. dotNet环境

Win2003EE sp2,IIS 6.0,.NET 3.5 sp1

2.PHP环境

CentOS 6.2, Apache 2.2.21, PHP 5.3.8, APC 3.1.9,mysql 5.5.16
PHP和mysql在同一server上

3.测试工具

Apache ab.exe

二、代码

注：mysql连接都使用持久连接

1.dotNet代码

[WebMethod] public string dsMysql() { DataSet dataset = new DataSet(); MySqlConnection conn = new MySqlConnection("Database=test;User Id=root;Password=ikmbikmb;Data Source=192.168.1.121;Port=3306;Pooling=true;Max Pool Size=10;Min Pool Size=1"); MySqlDataAdapter adapter = new MySqlDataAdapter(); adapter.SelectCommand = new MySqlCommand("SELECT * FROM t1", conn); adapter.Fill(dataset); JSON_Class Object_JSON_Class = new JSON_Class(); string tb = Object_JSON_Class.CreateJsonParameters(dataset.Tables[0]); return tb; }

2.php代码

(1)直接查询mysql代码 <?php $link = mysql_pconnect("192.168.1.121", "root", "ikmbikmb") or die("Could not connect : " . mysql_error()); mysql_select_db("test") or die("Could not select database"); $query = "SELECT * FROM t1"; $result = mysql_query($query) or die("Query failed : " . mysql_error()); print "<table>\n"; while ($line = mysql_fetch_array($result, MYSQL_ASSOC)) { print "\t<tr>\n"; foreach ($line as $col_value) { print "\t\t<td>$col_value</td>\n"; } print "\t</tr>\n"; } print "</table>\n"; mysql_free_result($result); mysql_close($link); ?>
(2)调用WebService代码 <?php $objSoapClient = new SoapClient("http://192.168.1.119/Service1.asmx?WSDL"); $out=$objSoapClient->dsMysql(); $json=$out->dsMysqlResult; $t=json_decode($json, true); $t=$t['Head']; print "<table>\n"; foreach ($t as $line) { print "\t<tr>\n"; foreach ($line as $col_value) { print "\t\t<td>$col_value</td>\n"; } print "\t</tr>\n"; } ?>

三、测试结果

说明：只列出结果关键参数

1.第一组测试10个并发

(1)直接查询
Requests per second: 334.20 [#/sec] (mean)
Time per request: 29.922 [ms] (mean)
Time per request: 2.992 [ms] (mean, across all concurrent requests)
Transfer rate: 133.87 [Kbytes/sec] received

(2)调用WebService
Requests per second: 184.51 [#/sec] (mean)
Time per request: 54.197 [ms] (mean)
Time per request: 5.420 [ms] (mean, across all concurrent requests)
Transfer rate: 72.39 [Kbytes/sec] received

2.第二组测试50个并发

(1)直接查询
Requests per second: 318.36 [#/sec] (mean)
Time per request: 157.053 [ms] (mean)
Time per request: 3.141 [ms] (mean, across all concurrent requests)
Transfer rate: 127.99 [Kbytes/sec] received

(2)调用WebService
Requests per second: 182.86 [#/sec] (mean)
Time per request: 273.427 [ms] (mean)
Time per request: 5.469 [ms] (mean, across all concurrent requests)
Transfer rate: 71.63 [Kbytes/sec] received

四、结果分析

直接查询比调用WebService大概快77%
(((334.20+318.36)/2)/((184.51+182.86)/2)-1)*100%
可能的原因：
1. 调用WebService增加了网络连接成本
2. 调用WebService在.net端和php都增加了对象的序列化计算成本
