WSO2 API 管理器：处理“大”有效负载的错误？

Question

向 WSO2 API (1.6.0) 上的已发布服务发送 SOAP 请求，在本例中为 5 MB XML 文本，服务器无法正确响应。我们期望一个正常的 SOAP 响应。如果我们直接将请求发送到后端服务器，则消息被成功处理。可能有什么问题。

WSO2 AM 的日志文件 wso2carbon.log 显示以下消息：

请求如下：

 <soapenv:Envelope
 xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/">   
 <soapenv:Header/>    <soapenv:Body>
       <leesAanvraag>
          <aanvraagNummer>123</aanvraagNummer>
       </leesAanvraag> ... repeat until size of message is 5M
       <leesAanvraag>
          <aanvraagNummer>123</aanvraagNummer>
       </leesAanvraag>
       <leesAanvraag>
          <aanvraagNummer>123</aanvraagNummer>
       </leesAanvraag>          
  </soapenv:Body> </soapenv:Envelope>

更新：我尝试了一个 32KB 的有效负载，多次发送此有效负载后，出现错误并且 WSO2 API 管理器没有给出正确的响应。

  <?xml version="1.0" encoding="UTF-8"?><soapenv:Envelope 
 xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/"><soapenv:Body><soapenv:Fault><faultcode
 xmlns:axis2ns1="http://schemas.xmlsoap.org/soap/envelope/">axis2ns1:Server</faultcode><faultstring>Error

 Sender</faultstring></soapenv:Fault></soapenv:Body></soapenv:Envelope>

会不会和这个issueor this有关？

Answer 1

请输入/repository/conf/passthru-http.properties 中的超时值

http.socket.timeout=120000（默认值为60000，120000是我们用于负载测试的值）
