Jquery XML POST未正确设置请求

Question

我有休息服务，我试图通过jquery客户端调用它。当我通过CURL发送如下响应时，后端休息服务可以找到。

curl -H "Accept: text/plain" -X POST -d 'host=<type:hostDescription xmlns:type="http://schemas.airavata.apache.org/gfac/type"><type:hostName>testHost5</type:hostName><type:hostAddress>aaaa</type:hostAddress></type:hostDescription>' http://localhost:6060/airavata-registry-rest-services/registry/api/hostdescriptor/save

此请求如下所示。

POST /airavata-registry-rest-services/registry/api/hostdescriptor/save HTTP/1.1
User-Agent: curl/7.22.0 (x86_64-pc-linux-gnu) libcurl/7.22.0 OpenSSL/1.0.1 zlib/1.2.3.4 libidn/1.23 librtmp/2.3

host=<type:hostDescription xmlns:type="http://schemas.airavata.apache.org/gfac/type">
   <type:hostName>testHost5</type:hostName>
   <type:hostAddress>aaaa</type:hostAddress></type:hostDescription>

但问题是我的jquery客户端发送的请求如下所示。

POST /airavata-registry-rest-services/registry/api/hostdescriptor/save HTTP/1.1

我的jquery代码片段如下所示;

$('[name="btn2"]').click(function(){
            var hostName = $("#hostName1").val();
            var hostAddress = $("#hostAddress1").val();

            var xml = $('<type:hostDescription xmlns:type="http://schemas.airavata.apache.org/gfac/type"><type:hostName>' + hostName + '</type:hostName><type:hostAddress>' + hostAddress + '</type:hostAddress></type:hostDescription>');

            var xmlData= $(xml);
            var xmlString;
            if (window.ActiveXObject){
                xmlString = xmlData.xml;
            } else {
                var oSerializer = new XMLSerializer();
                xmlString = oSerializer.serializeToString(xmlData[0]);
            }
            console.log(xmlString);

            $.post("http://localhost:6060/airavata-registry-rest-services/registry/api/hostdescriptor/save",
                    { host: xmlString} ,function(data,status){
                        alert("Data: " + data + "\nStatus: " + status);
                        alert("button2 post sent !");
                    });
        });

我应该如何更改我的客户端以正确调用此服务。
