关于php调用webservice的问题

Question

能不能说的具体一点怎么传，并且还有一个Content-Length不知道该怎么办。

Answer 1

Content-Length就是报文的串长度.报文报头格式都给你了,套入socket请求即可.
用csdn的webservice当例子.
调用方法的格式说明在这里
http://forum.csdn.net/OpenApi/forumapi.asmx?op=GetUserProfile
$user  = '你的csdn帐号';
$pass  = '帐号密码';
$friend = '你的csdn帐号';//要查询的帐号

$fn = fsockopen('forum.csdn.net',80,$errstr,$errno,1);
if(!$fn)
{
exit($errstr);
}
$post = <<<POST
<?xml version="1.0" encoding="utf-8"?>
<soap:Envelope xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/">
  <soap:Body>
    <GetUserProfile xmlns="http://www.csdn.net/">
      <identity>
        <username>{$user}</username>
        <password>{$pass}</password>
      </identity>
      <username>{$friend}</username>
    </GetUserProfile>
  </soap:Body>
</soap:Envelope>
POST;
fwrite($fn,"POST /OpenApi/forumapi.asmx HTTP/1.1\r\n");
fwrite($fn,"Host: forum.csdn.net\r\n");
fwrite($fn,"Content-Type: text/xml; charset=utf-8\r\n");
fwrite($fn,"Connection:close\r\n");
fwrite($fn,"Content-Length:".strlen($post)."\r\n\r\n");

fwrite($fn,$post);
while(!feof($fn))
{
$return .= fgets($fn,1024);
}
fclose($fn);

echo "<xmp>".$return."</xmp>";//帐户的信息,xml格式

Answer 2

用curl更好,content-length头会自动生成.

Answer 3

谢谢解答，我照着你的代码改了改，结果出错了。
错误原因是：Server was unable to process request. ---&gt; Name cannot begin with the '&lt;' character, hexadecimal value 0x3C. Line 1, position 2.
能不能帮忙看下错在哪，我觉得变量的名字没问题啊代码如下
 $username='wanger';
        $password='123456abc!';
        $ToITPhoneNo='00653218569745';
        
        $fn = fsockopen('www.internettelecom.com.sg',80,$errstr,$errno,1);
        if(!$fn)
        {
            exit($errstr);    
        }
        $post = "<<
<?xml version=\"1.0\" encoding=\"utf-8\"?>
<soap:Envelope xmlns:xsi=\"http://www.w3.org/2001/XMLSchema-instance\" xmlns:xsd=\"http://www.w3.org/2001/XMLSchema\" xmlns:soap=\"http://schemas.xmlsoap.org/soap/envelope/\">
  <soap:Body>
    <GetLogin xmlns=\"http://www.internettelecom.com.sg/IPhoneWS/\">
      <UserName>".$username."</UserName>
      <Password>".$password."</Password>
      <ToITPhoneNo>".$ToITPhoneNo."</ToITPhoneNo>
    </GetLogin>
  </soap:Body>
</soap:Envelope>";        fwrite($fn,"POST /IPhoneWS/IPhoneWebService.asmx HTTP/1.1\r\n");
        fwrite($fn,"Host: www.internettelecom.com.sg\r\n");
        fwrite($fn,"Content-Type: text/xml; charset=utf-8\r\n");
        fwrite($fn,"Connection:close\r\n");
        fwrite($fn,"Content-Length:".strlen($post)."\r\n\r\n");
    
        fwrite($fn,$post);
        while(!feof($fn))
        {
            $return .= fgets($fn,1024);    
        }
        fclose($fn);
        
        echo "<xmp>".$return."</xmp>";

Answer 4

注意细节问题 $username='wanger';
        $password='123456abc!';
        $ToITPhoneNo='00653218569745'; $fn = fsockopen('www.internettelecom.com.sg',80,$errstr,$errno,1);
if(!$fn)
{
exit($errstr);
}
//你的$post = "<<...";明显是有问题的.
$post = <<<POST
<?xml version="1.0" encoding="utf-8"?>
<soap:Envelope xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/">
  <soap:Body>
    <GetLogin xmlns="http://www.internettelecom.com.sg/IPhoneWS/">
      <UserName>{$username}</UserName>
      <Password>{$password}</Password>
      <ToITPhoneNo>{$ToITPhoneNo}</ToITPhoneNo>
    </GetLogin>
  </soap:Body>
</soap:Envelope>
POST;
fwrite($fn,"POST /IPhoneWS/IPhoneWebService.asmx HTTP/1.1\r\n");
fwrite($fn,"Host: www.internettelecom.com.sg\r\n");
fwrite($fn,"Content-Type: text/xml; charset=utf-8\r\n");
fwrite($fn,"Connection:close\r\n");
fwrite($fn,"Content-Length:".strlen($post)."\r\n\r\n");

fwrite($fn,$post);
while(!feof($fn))
{
$return .= fgets($fn,1024);
}
fclose($fn);

echo "<xmp>".$return."</xmp>";
按照以上代码,可以返回GetLoginResponse,接下来是你调用方法的参数问题,自己去查使用手册,或者问webservice的提供商
http response :HTTP/1.1 200 OK

Answer 5

得到的数据应该怎么读取？比如我要读取GetLoginResult的值，是不是用读取xml的方法？我用下面的代码来读取，结果什么也没得到。。
$xml = new DOMDocument();
$xml->load($rs);
$envelope = $xml->getElementsByTagName( "soap:Envelope" );$body = $envelope->getElementsByTagName( "soap:Body" );

$GetLoginResponse = $body->getElementsByTagName( "GetLoginResponse" );$GetLoginResult = $GetLoginResponse->getElementsByTagName( "GetLoginResult" );if( strcmp($GetLoginResult,"err02")==0 ){
echo "00000000000";
}else{
echo "11111111111";
}

Answer 6

上面的$rs="<xmp>".$return."</xmp>";
