无法从帖子请求中获取字符串数据

Question

我做了一个Servlet，它应该在post请求中接收包含XML数据的字符串，字符串就像这样发送

  <?xml version="1.0" encoding="UTF-8"?>
    <ocsRequest>
   <requestType>2015</requestType>
   <serviceNode>xx</serviceNode>
   <sequenceNo>1463918615065</sequenceNo>
   <callingParty>9656500000</callingParty>
   <serviceType>P-aRX2zvEwMY2</serviceType>
   <serviceId>S-NgY2zvxxxx</serviceId>
   <bearerId>SMS</bearerId>
   <chargeAmount>60.0</chargeAmount>
   <planId>Fit_DuSxxxx</planId>
   <asyncFlag>N</asyncFlag>
   <renewalFlag>-1</renewalFlag>
   <bundleType>N</bundleType>
   <serviceUsage>-1</serviceUsage>
   <promoId>-1</promoId>
   <subscriptionFlag>S</subscriptionFlag>
   <optionalParameter1>msgText#Follow this link, or try from PC. http://localhost:8084/Notification/contents/ddd.mp3</optionalParameter1>
   <optionalParameter2>reqSource#1319</optionalParameter2>
   <optionalParameter3>languageId#en</optionalParameter3>
   <optionalParameter4>-1</optionalParameter4>
   <optionalParameter5>-1</optionalParameter5>
</ocsRequest>

但是当我尝试像这样接收它时

String xmlContent = request.getParameter("xmlContent");
out.write(xmlContent);

它给了我

<ocsRequest>
    <requestType>2015</requestType>
    <serviceNode>FITxxx</serviceNode>
    <sequenceNo>1463918615065</sequenceNo>
    <callingParty>96565682860</callingParty>
    <serviceType>P-aRX2zvEwMY2</serviceType>
    <serviceId>S-NgY2zvEwMY2Du</serviceId>
    <bearerId>SMS</bearerId>
    <chargeAmount>60.0</chargeAmount>
    <planId>Fit_DuSudai_60</planId>
    <asyncFlag>N</asyncFlag>
    <renewalFlag>-1</renewalFlag>
    <bundleType>N</bundleType>
    <serviceUsage>-1</serviceUsage>
    <promoId>-1</promoId>
    <subscriptionFlag>S</subscriptionFlag>
    <optionalParameter1>msgText

字符串未完成，它在msgText

之后缺少某些部分

我也尝试在get请求中发送字符串，但遇到同样的问题
