如何在SOAP请求中设置字符编码 [英] How to set character encoding in SOAP request

问题描述

我从Java中的Web servlet调用SAP SOAP服务。由于某种原因，SAP每次在我的请求的字段中使用特殊字符（如è或à）时都会给我一个错误。 SOAP服务的WSDL是在UTF-8中定义的，我已经相应地设置了我的字符编码，如下所示。但我不知道这是正确的方式。此外，请注意，如果我使用SOAP UI（具有相同的信封）请求正确工作，因此它必须是Java端的东西。

  URL url = new URL（SOAP_URL）; 
 String authorization = Base64Coder.encodeString（SOAP_USERNAME +：+ SOAP_PASSWORD）; 
 String envelope =< soapenv：Envelope xmlns：soapenv ='http：//schemas.xmlsoap.org/soap/envelope/'xmlns：urn ='urn：sap-com：document：sap：soap：功能：mc-style'>< soapenv：Header />< soapenv：Body>< urn：ZwsMaintainTkt>< item>à< / item>< / urn：ZwsMaintainTkt>< / soapenv：Body> ;< / soapenv：Envelope>; 
 HttpURLConnection con =（HttpURLConnection）url.openConnection（）; 
 con.setReadTimeout（SOAP_TIMEOUT）; 
 con.setRequestMethod（POST）; 
 con.setRequestProperty（Content-type，text / xml; charset = utf-8）; 
 con.setRequestProperty（SOAPAction，SOAP_ACTION_ZWSMANTAINTKT）; 
 con.setRequestProperty（Authorization，Basic+ authorization）; 
 con.setDoOutput（true）; 
 con.setDoInput（true）; 
 OutputStreamWriter outputStreamWriter = new OutputStreamWriter（con.getOutputStream（））; 
 outputStreamWriter.write（envelope）; 
 outputStreamWriter.close（）; 
 InputStream inputStream = con.getInputStream（）; 
  

解决方案

1. soap-request是xml使用xml标头来指定您的请求的编码：

   
   
   

   <？xml version =1.0encoding =UTF-8？>




2. new OutputStreamWriter（con.getOutputStream / code>使用平台默认编码，这很可能是ISO8859的一些风味。 使用 new OutputStreamWriter（con.getOutputStream（），UTF-8）

   I am calling a SAP SOAP Service from a web servlet in Java. For some reason SAP is giving me an error every time I use special characters in the fields of my request such as 'è' or 'à'. The WSDL of the SOAP Service is defined in UTF-8 and I have set my character encoding accordingly as you can see below. However I am not sure this is the correct way. Also, notice that if I use SOAP UI (with the same envelope) the request works correctly so it must be something on Java side.

   URL url = new URL(SOAP_URL);
   String authorization = Base64Coder.encodeString(SOAP_USERNAME + ":" + SOAP_PASSWORD);
   String envelope = "<soapenv:Envelope xmlns:soapenv='http://schemas.xmlsoap.org/soap/envelope/' xmlns:urn='urn:sap-com:document:sap:soap:functions:mc-style'><soapenv:Header/><soapenv:Body><urn:ZwsMaintainTkt><item>à</item></urn:ZwsMaintainTkt></soapenv:Body></soapenv:Envelope>";
   HttpURLConnection con = (HttpURLConnection) url.openConnection();
   con.setReadTimeout(SOAP_TIMEOUT);
   con.setRequestMethod("POST");
   con.setRequestProperty("Content-type", "text/xml; charset=utf-8");
   con.setRequestProperty("SOAPAction", SOAP_ACTION_ZWSMANTAINTKT);
   con.setRequestProperty("Authorization", "Basic " + authorization);
   con.setDoOutput(true);
   con.setDoInput(true);
   OutputStreamWriter outputStreamWriter = new OutputStreamWriter(con.getOutputStream());
   outputStreamWriter.write(envelope);
   outputStreamWriter.close();
   InputStream inputStream = con.getInputStream();
   

   解决方案

   1. Since a soap-request is xml use the xml-header to specify the encoding of your request:

      <?xml version="1.0" encoding="UTF-8"?>

   2. new OutputStreamWriter(con.getOutputStream()) uses the platform-default encoding which most probably is some flavour of ISO8859. Use new OutputStreamWriter(con.getOutputStream(),"UTF-8") instead
