2010 – Do I need permissions to run SPServices on Sharepoint?

I need help with Sharepoint. I have tried several ways to recover data from a list and I have had little or no success. After many readings and research, I am still not more advanced.

I use a list made by another user, to which I can add, edit, and delete items. When calling this list with the help of SPServices, it seems like I hit a wall. This is my third attempt to try to access the list and I have now received a 404 answer and responseText is zero.

The URL is correct because it actually loads the list of values.

If I have an empty webURL parameter, I get a real SOAP responseText declaring the following:

soap: serverAn exception of type Microsoft.SharePoint.SoapServer.SoapServerException & # 39; has been lifted.
    The list does not exist.
The page you selected contains a list that does not exist. It may have been deleted by another user.

Here is my call which, when I set the web URL for it to point to the list, always returns a 404 http, regardless of the URL:

getListItems_RFC () {function
var url = $ (). SPServices.SPGetCurrentSite () +
console.log ("getListItems_RFC ()" + url);
$ (). SPServices ({
operation: "GetListItems",
webURL: url,
async: false,
listName: "RFC Preview",
CAMLViewFields: ""
function (xData, Status) {
console.log (state); // output error
console.log (xData); // output an array of responses: Text: null and status: 404
$ (xData.responseXML) .SPFilterNode ("m: properties"). each (function () {
var liHtml = "
  • "+ $ (this) .attr (" d: Title ") +"
  • "; $ ("# debug"). append (liHtml); }); } }); };

    I've changed the URL in every possible way:

    var url = $ (). SPServices.SPGetCurrentSite () +
    "/_Vti_bin/listdata.svc/"; // responseText = null, status: 404
    var url = $ (). SPServices.SPGetCurrentSite (); // responseText = null, status: 404
    var url = "" // responseText = soap response above, status: 500

    Why it does not work ??? What am I doing wrong ???
