在手冊中有人提供了一個例子,但是不支持中文, 並且沒有告訴在客戶端返回結果後怎麼處理這個結果. 自己苦搞半天終於搞明白了,其實可以很輕松讓他支持中文, 並且幾乎不需要做任何額外的工作.
下面是他原來的例子(可以在手冊中找到):
/* 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);
?>
這個例子中客戶端得到$response後沒有作任何的處理,這個返回值是這個樣子的字符串:
HTTP/1.1 200 OK
Date: Thu, 04 Nov 2004 08:21:43 GMT
Server: apache/2.0.47 (Win32) PHP/5.0.1
X-Powered-By: PHP/5.0.1
Connection: close
Content-Type: text/XML;charset=GB2312
<?XML version="1.0" encoding="iso-8859-1"?>
<methodResponse>
<params>
<param>
<value>
<string>All eggs will be birds one day.</string>
</value>
</param>
</params>
</methodResponse>
這個字符串包含了兩個部分,一個是Html的頭信息,一個是XML-rpc包文件,對他稍微進行一下處理就可以滿足我們的要求了.
下面看看我修改過的例子,主要用了一個XMLrpc_decode函數,網上沒有找到說明,自己試了半天,才試出來他的用法:
/* clIEnttest.PHP */
<?PHP
function do_call($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);
?>
運行一下,看看顯示的數組的樣式,這樣處理起來就舒服多了.
明白了這個,別閒著,看看PHP5自帶的"SOAP Functions",使用方法和工作原理,大同小異啊.
