在手册中有人提供了一个例子,但是不支持中文, 并且没有告诉在客户端返回结果后怎么处理这个结果. 自己苦搞半天终于搞明白了,其实可以很轻松让他支持中文, 并且几乎不需要做任何额外的工作.
下面是他原来的例子(可以在手册中找到):
/* clienttest.php */
<?php
function do_call($host, $port, $request) {
$fp = fsockopen($host, $port, $errno, $errstr);
$query = "POST /servertest.php HTTP/1.0\nUser_Agent: My Egg Client\nHost: ".$host."\nContent-Type: text/xml\nContent-Length: ".strlen($request)."\n\n".$request."\n";
if (!fputs($fp, $query, strlen($query))) {
$errstr = "Write error";
return 0;
}
$contents = @#@#;
while (!feof($fp)) {
$contents .= fgets($fp);
}
fclose($fp);
return $contents;
}
$host = @#localhost@#;
$port = 80;
$request = xmlrpc_encode_request(@#cycle@#, @#egg@#);
$response = do_call($host, $port, $request);
/* do something with $response, e.g. print it */
?>
/* servertest.php */
<?php
function lifecycle($method, $params) {
/* $method = @#cycle@#, $params = (array of) request parameter(s); $data is also passed from xmlrpc_server_call_method, if we had any data to pass */
switch($params[0]) {
case @#egg@#:
$reply = @#All eggs will be birds one day.@#;
break;
default:
$reply = @#That must have been an otheregg@#;
}
return $reply;
}
$server = xmlrpc_server_create();
/* register the @#external@# name and then the @#internal@# name */
xmlrpc_server_register_method($server, "cycle", "lifecycle");
$request = $HTTP_RAW_POST_DATA; // no you don@#t need @#always on@#, and no $_POST doesn@#t work.
/* the parameters here are @#server, xml-string and user data@#. There@#s supposed to be an optional @#output options@# array too, but I can@#t get it working :( hence header() call */
$response = xmlrpc_server_call_method($server, $request, null);
header(@#Content-Type: text/xml@#);
print $response;
xmlrpc_server_destroy($server);
?>
这个例子中客户端得到$response后没有作任何的处理,这个返回值是这个样子的字符串:
HTTP/1.1 200 OK
Date: Thu, 04 Nov 2004 08:21:43 GMT
Server: Apache/2.0.47 (Win32) PHP/5.0.1
X-Powered-By: PHP/5.0.1
Connection: close
Content-Type: text/xml;charset=GB2312
<?xml version="1.0" encoding="iso-8859-1"?>
<methodResponse>
<params>
<param>
<value>
<string>All eggs will be birds one day.</string>
</value>
</param>
</params>
</methodResponse>
这个字符串包含了两个部分,一个是html的头信息,一个是xml-rpc包文件,对他稍微进行一下处理就可以满足我们的要求了.
下面看看我修改过的例子,主要用了一个xmlrpc_decode函数,网上没有找到说明,自己试了半天,才试出来他的用法:
/* clienttest.php */
<?php
function do_call($host, $port, $request) {
$fp = fsockopen($host, $port, $errno, $errstr);
$query = "POST /servertest.php HTTP/1.0\nUser_Agent: My Egg Client\nHost: ".$host."\nContent-Type: text/xml\nContent-Length: ".strlen($request)."\n\n".$request."\n";
if (!fputs($fp, $query, strlen($query))) {
$errstr = "Write error";
return 0;
}
$contents = @#@#;
while (!feof($fp)) {
$contents .= fgets($fp);
}
fclose($fp);
return $contents;
}
$host = @#localhost@#;
$port = 80;
$request = xmlrpc_encode_request(@#cycle@#, @#egg@#);
$response = do_call($host, $port, $request);
/* do something with $response, e.g. print it */
$pos = strpos($response, @#<?xml@#);
$str = substr($response, $pos);
$tmp = xmlrpc_decode($str);
print_r($tmp);
/* do something with $tmp e.g. print it */
?>
/* servertest.php */
<?php
function lifecycle($method, $params) {
/* $method = @#cycle@#, $params = (array of) request parameter(s); $data is also passed from xmlrpc_server_call_method, if we had any data to pass */
switch($params[0]) {
case @#egg@#:
$reply[] = @#All eggs will be birds one day.我市好人@#;
$reply[] = @#All eggs will be birds one day.我市好人aaaaa@#;
break;
default:
$reply[] = @#That must have been an otheregg我市好人@#;
}
return $reply;
}
$server = xmlrpc_server_create();
/* register the @#external@# name and then the @#internal@# name */
xmlrpc_server_register_method($server, "cycle", "lifecycle");
$request = $HTTP_RAW_POST_DATA; // no you don@#t need @#always on@#, and no $_POST doesn@#t work.
/* the parameters here are @#server, xml-string and user data@#. There@#s supposed to be an optional @#output options@# array too, but I can@#t get it working :( hence header() call */
$response = xmlrpc_server_call_method($server, $request, null);
header(@#Content-Type: text/xml@#);
print ($response);
xmlrpc_server_destroy($server);
?>
运行一下,看看显示的数组的样式,这样处理起来就舒服多了.
明白了这个,别闲着,看看php5自带的"SOAP Functions",使用方法和工作原理,大同小异啊.
