SAPUI5内置的AJAX类库，在提交POST请求的时候，忽略了http headers。GET请求没有这个问题。

下面的代码不能提交HTTP Headers

sUrl = getSMPURL() + "/odata/applications/latest/com.sap.flight.kapsel/Connections";
$.ajax({
    type : "POST",cache : false,url: sUrl,data: payload,beforeSend : function(request) {
        request.setRequestHeader('Content-Type',"application/xml");
    },success : function(data,ajaxOptions,xhr) {
        alert("passed register");
    },error : function(xhr,thrownError) {
        alert("shit");
    },xhrFields : {
        withCredentials : true,}
});

下面的代码可以提交HTTP Headers

这里写代码片
sUrl = getSMPURL() + “/odata/applications/latest/com.sap.flight.kapsel”;
$.ajax({
headers: {
‘Authorization’: “Basic ” + btoa(getUserName() + “:” + getPassword())
},
type : “GET”,
cache : false,
url: sUrl,
dataType:’xml’,
beforeSend : function(request) {

},xhr) {
        alert("passed authentication");
    },}
});
