Zend_XmlRpc_Client會強調在主機

Question

運行與Zend的一個問題，因爲它拋出一個錯誤。我相信這是由於Zend在URL中的下劃線所致。

我有一個Python客戶端，做同樣的基本功能，它按預期工作。

想知道如果有一個PHP

錯誤解決方法：

Fatal error: Uncaught exception 'Zend_Uri_Exception' with message 'Invalid URI supplied' in /usr/share/php/libzend-framework-php/Zend/Uri/Http.php:156 
Stack trace:

PHP：

ini_set("include_path", "/usr/share/php/libzend-framework-php"); 
require_once('Zend/XmlRpc/Client.php'); 

$server = new Zend_XmlRpc_Client('http://local_server_foo/xmlrpc.server.php'); 

// Get the HTTP Client used by the XMLRPC client and Increase the HTTP timeout 
$server->getHttpClient()->setConfig(array('timeout'=>30)); 

$client = $server->getProxy(); 

$request = array(
    array(
     'methodName' => 'system.listMethods', 
     'params'  => array() 
    ) 
); 

try { 
    $response = $client->system->multicall($request); 
    echo print_r($response,true); 
} catch (Zend_XmlRpc_Client_HttpException $e) { 
    echo 'HTTP Exception: '."\n"; 
    echo $e->getCode(); 
    echo $e->getMessage(); 
} catch (Zend_XmlRpc_Client_FaultException $e) { 
    echo 'Fault Exception: '."\n"; 
    echo $e->getCode(); 
    echo $e->getMessage(); 
} 

的Python（這工作）：

#!/usr/bin/python 

import xmlrpclib 

servAddr = "http://local_server_foo/xmlrpc.server.php" 

client = xmlrpclib.ServerProxy(servAddr) 

print 

methods = client.system.listMethods() 
for m in methods: 
    print m + "\tHelp Documentation: " + client.system.methodHelp(m) 
    print

從http://en.wikipedia.org/wiki/Hostname（可鏈接到相關的RFC）：

The Internet standards (Request for Comments) for protocols mandate that component hostname labels may contain only the ASCII letters 'a' through 'z' (in a case-insensitive manner), the digits '0' through '9', and the hyphen ('-'). The original specification of hostnames in RFC 952, mandated that labels could not start with a digit or with a hyphen, and must not end with a hyphen. However, a subsequent specification (RFC 1123) permitted hostname labels to start with digits. No other symbols, punctuation characters, or white space are permitted.

While a hostname may not contain other characters, such as the underscore character (_), other DNS names may contain the underscore.[3] Systems such as DomainKeys and service records use the underscore as a means to assure that their special character is not confused with hostnames. For example, _http._sctp.www.example.com specifies a service pointer for an SCTP capable webserver host (www) in the domain example.com.

具有主機名下劃線是無效的，而Zend框架的驗證工作正常。

我剛剛在版本1.11.9中檢查過沒有人抱怨過;也許我應該最終提交一份錯誤報告。我修改/更新Zend_Validate_Hostname類，以便像下面幾行一樣自己填寫缺失的下劃線。它在isValid()方法，這取決於你的版本在線路621（1.11.2）到655（1.11.9）。

老線：

$regexLocal = '/^(([a-zA-Z0-9\x2d]{1,63}\x2e)*[a-zA-Z0-9\x2d]{1,63}){1,254}$/'; 
$status = @preg_match($regexLocal, $value); 

新線：注意變化x5f

$regexLocal = '/^(([a-zA-Z0-9\x2d\x5f]{1,63}\x2e)*[a-zA-Z0-9\x2d]{1,63}){1,254}$/'; 
$status = @preg_match($regexLocal, $value); 

UDPATE讓我們完善這個：

由於@Just^h指出了他的答案下劃線是不允許的，但仍然被廣泛使用。讓我們指責這是在IBM和後來的Microsoft上使用NetBIOS，但爲什麼在本地主機名稱中使用了「儘管不允許」，儘管不允許。

作爲一名前工程師服務器我在大公司見過很多內部網，他們都慷慨的主機名稱中使用下劃線。 OS/2和Windows管理員不知不覺地在DNS命名方案中使用它們。這就是所有瀏覽器都支持它的原因，所有的Web服務器都支持它。
