求助啊，用eureka restAPI注册服务的时候一直给我报400cannot parse request body

[学步]

我用eureka restAPI注册服务，就是官方给的这个接口POST /eureka/v2/apps/appID ；
xml如下：
<?xml version="1.0" encoding="utf-8"?>
<instance>
<hostName>LAPTOP-2GAODBTS</hostName>
<app>testservice</app>
<ipAddr>169.254.206.162</ipAddr>
<vipAddress>testservice</vipAddress>
<secureVipAddress>str1234</secureVipAddress>
<status>UP</status>
<port>8080</port>
<securePort>443</securePort>
<homePageUrl>http://LAPTOP-2GAODBTS:8080/</homePageUrl>
<statusPageUrl>http://LAPTOP-2GAODBTS:8080/Status</statusPageUrl>
<dataCenterInfo>
<name>MyOwn</name>
</dataCenterInfo>
<leaseInfo>

一直返回：
<error>
<message>cannot parse request body</message>
</error>

求哪位大神指点一下

<evictionDurationInSecs>745</evictionDurationInSecs>
</leaseInfo>
<metadata/>
</instance>
