请教一个php调用webservice的问题

[aizlcm]

地址 ：http://172.16.33.26/purchase/Service1.asmx?wsdl

$client = new Soap_Client("http://172.16.33.26/purchase/Service1.asmx?wsdl");

我这样调用错误。
由于接口只有内网才能打开，我把代码贴出来

我是个新手，请问现在我应该如何调用？

[aizlcm]

$client = new SoapClient($Url); 不能使用这种方法调用

[aizlcm]

求调用的方法

[xuzuning]

如果使用 soap 扩展 $client = new SoapClient("http://172.16.33.26/purchase/Service1.asmx?wsdl"); 如果使用 nusoap 类库 $client = new Soap_Client("http://172.16.33.26/purchase/Service1.asmx?wsdl"); 关键是你要把 WSDL 文件搞正确了

[aizlcm]

上面发错了

$client = new SoapClient($this->serviceUrl);

错误：SOAP-ERROR: Parsing WSDL: Couldn't load from 'http://172.16.33.26/purchase/Service1.asmx?wsdl' : failed to load external entity "http://172.16.33.26/purchase/Service1.asmx?wsdl"

[xuzuning]

方法
Array
(
    [0] => InvoiceResponse Invoice(Invoice $parameters)
    [1] => InvoiceResponse Invoice(Invoice $parameters)
)
数据结构
Array
(
    [0] => struct Invoice {
 string kprqq;
 string kprqz;
 string SAPNUMBER;
}
    [1] => struct InvoiceResponse {
 string InvoiceResult;
}
)

有什么问题请直说

[xuzuning]

可能是你的 WSDL 有 BOM 头或开始处有空行引起的 我解析你的 WSDL 时就发现开始处有空行，还以为是复制的问题呢

[猪崽儿0o0]

PHP调用webservice就是按照接口类型和需要传递的参数组装好后使用soap协议发送过去后会返回对应的结果给你，然后接收后做处理即可。
