force.com流接口

Question

我正在尝试Force.com Streaming API demo，但得到以下错误：

<?xml version="1.0" encoding="UTF-8"?>
<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" xmlns:sf="urn:fault.partner.soap.sforce.com" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
    <soapenv:Body><soapenv:Fault>
        <faultcode>UNKNOWN_EXCEPTION</faultcode>
        <faultstring>UNKNOWN_EXCEPTION: Element type &quot;soapenv:Envelope&quot; must be followed by either attribute specifications, &quot;&gt;&quot; or &quot;/&gt;&quot;.   </faultstring>
        <detail>
            <sf:UnexpectedErrorFault xsi:type="sf:UnexpectedErrorFault">   
                <sf:exceptionCode>UNKNOWN_EXCEPTION</sf:exceptionCode>
                <sf:exceptionMessage>Element type &quot;soapenv:Envelope&quot; must be followed by either attribute specifications, &quot;&gt;&quot; or &quot;/&gt;&quot;.</sf:exceptionMessage>
            </sf:UnexpectedErrorFault>  
        </detail> 
    </soapenv:Fault></soapenv:Body>
</soapenv:Envelope>

第22行有一个放错位置的double quote，编译器没有捕获它。

替换此代码：

private static final String ENV_START =
"
"<soapenv:Envelope xmlns:soapenv='http://schemas.xmlsoap.org/soap/envelope/'
         + "xmlns:xsi='http://www.w3.org/2001/XMLSchema-instance' " +
         "xmlns:urn='urn:partner.soap.sforce.com'><soapenv:Body>";

使用以下代码：

private static final String ENV_START =
    "<soapenv:Envelope xmlns:soapenv='http://schemas.xmlsoap.org/soap/envelope/'"
    + "xmlns:xsi='http://www.w3.org/2001/XMLSchema-instance' " +
         "xmlns:urn='urn:partner.soap.sforce.com'><soapenv:Body>";
