Question

我正在尝试将SOAP API添加到APIM 1.10.0。

首先，我将尝试使用以下CURL测试SOAP服务本身。该服务应返回给定城市/国家的天气状况：

curl -X POST -T soap.xml -H "Content-Type: text/xml"  \
      "http://www.webservicex.net/globalweather.asmx"

提供以下soap.xml：

<?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>
    <GetWeather xmlns="http://www.webserviceX.NET">
        <CityName>Eilat</CityName>
        <CountryName>Israel</CountryName>
    </GetWeather>
</soap:Body>
</soap:Envelope>

我得到了明智的回应！

现在我将此服务介绍给APIM，如下所示：

- Add new API
- I have a SOAP endpoint
    - WSDL URL: http://www.webservicex.net/globalweather.asmx?wsdl
    - Start Creating
        - Name: eilat
        - Context: /eilat
        - Version: 1.0.0
        - WSDL: http://www.webservicex.net/globalweather.asmx?wsdl  [tested ok]
        - Production Endpoint: http://www.webservicex.net/globalweather.asmx [valid]
        - Tier Availability: Unlimited

我订阅此API，并尝试以下CURL

curl -H "Authorization: Bearer <my-key>" -X POST -T soap.xml \
     -H "Content-Type: text/xml" http://localhost:8280/eilat/1.0.0

我收到以下回复：

<faultstring>unknown</faultstring>

在SOAP UI中尝试相同的操作，我得到：

<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/">
   <soapenv:Body>
      <soapenv:Fault>
         <faultcode>soapenv:Server</faultcode>
         <faultstring>unknown</faultstring>
         <detail/>
      </soapenv:Fault>
   </soapenv:Body>
</soapenv:Envelope>

        {org.apache.synapse.transport.passthru.ServerWorker}
        java.lang.NullPointerException

再次查看API，我看到WSDL URL已从我提供的URL更改为以下内容：

/registry/resource/_system/governance/apimgt/applicationdata/wsdls/admin--eilat1.0.0.wsdl

我想这是正常行为。

问题是 - 为什么空指针异常？

Answer 1

错误是由于自定义身份验证插件处理程序引起的。从处理程序链中删除此处理程序解决了这个问题。
