我有一个 WSDL，它有一个需要属性的元素:

<xsd:complexType name="claim">
  <xsd:annotation>
    <xsd:documentation>Claim Element</xsd:documentation>
  </xsd:annotation>
  <xsd:sequence>
    <!-- other elements removed -->
  </xsd:sequence>
  <xsd:attribute name="claimId" type="xsd:nonNegativeInteger" use="required" />
</xsd:complexType>

就生成的 xml 而言，它应该如下所示:

<claims>
    <claim claimId="1">
        <!-- elements removed -->
    </claim>
    <!-- more claims -->
</claims>

在 foreach 循环中，我将一组元素放在一起，并将属性用作键的一部分:

//$claim = array of key/value pairs
$claim = [...];
$claim = new \SoapVar($claim, SOAP_ENC_OBJECT, null, null, 'claim claimId="' . ($key+1) . '"');
$claims['claim claimId="'.($key+1).'"'] = $claim;

在将其传递给 SoapClient 时，元素被删除:

//$client = new \SoapClient($wsdl);
$client->checkClaims($claims);

但我得到的是:

<claims />

如何让我的 soap 客户端在 soap 调用中正确解析 claim 元素？

最佳答案

所以您的代码几乎没有问题。为此，您需要在 WSDL 模式下使用 SoapClient($client = new\SoapClient($wsdl);，您正在这样做)。下面的下一个是错误的

$claim = [...];
$claim = new \SoapVar($claim, SOAP_ENC_OBJECT, null, null, 'claim claimId="' . ($key+1) . '"');
$claims['claim claimId="'.($key+1).'"'] = $claim;

您不使用 'claim claimId="' . ($key+1) . '"' 添加属性。

现在您需要的是使用classmap。下面是我创建的用于显示 WSDL

from flask import Flask

app  = Flask(__name__)

@app.route("/ICalculator",methods=['get', 'post'])
def reply():
    return "<xmldata />"

@app.route("/app.wsdl")

    return """<wsdl:definitions

""".replace(r"\r", "").replace(r"\n", "")


if __name__ == "__main__":
   app.run(debug=True, host='0.0.0.0', port=5000)

然后用同样的方式运行

python3 wsdl.py

然后运行另一个socat来查看流量

socat -v TCP-LISTEN:5001,fork TCP:127.0.0.1:5000

接下来我写了一个示例 PHP 代码来展示 classmap 是如何工作的

<?php
class Claim {
  public function __construct(Array $properties=array()){
      foreach($properties as $key => $value){
        $this->{$key} = $value;
      }
    }
}

$test = new Claim(array('claimId'=>10, 'a'=> 22, 'b'=> 33));

$claim=new SoapVar($test, SOAP_ENC_OBJECT);
$wsdl = "http://localhost:5001/app.wsdl";
$client = new SoapClient($wsdl, array(
    'trace'        => 1,
    'encoding'     => 'UTF-8',
    'soap_version' => SOAP_1_1,
    'classmap'     => array('Claim' => 'Claim')
));
$client->add($claim);

结果 xml 是

<SOAP-ENV:Envelope xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/" xmlns:ns1="http://localhost:5001" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"><SOAP-ENV:Body><parameters claimId="10" xsi:type="ns1:Claim"><ns1:a>22</ns1:a><ns1:b>33</ns1:b></parameters></SOAP-ENV:Body></SOAP-ENV:Envelope>
