I am using this link for reference to fetch data from document library using Rest api.

The issue I am facing is I am getting junk data in result. Below is my code sample:

<button type='button' onclick="retriveItems()">Copy document</button>  <script src="https://ajax.aspnetcdn.com/ajax/jQuery/jquery-1.9.1.min.js" type="text/javascript"></script> <script type='text/javascript'>      function retriveItems() {     alert("Hello World");      var requesturi= "";     if((_spPageContextInfo.webAbsoluteUrl) && (_spPageContextInfo.webAbsoluteUrl.indexOf("sites")>0))     {         requesturi = _spPageContextInfo.webAbsoluteUrl + "/_api/web/GetFileByServerRelativeUrl('"+_spPageContextInfo.webServerRelativeUrl+"/Shared%20Documents/teghjhs.docx')/$ value";     }     else     {         requesturi = _spPageContextInfo.webAbsoluteUrl + "/_api/web/GetFileByServerRelativeUrl('/Shared%20Documents/teghjhs.docx')/$ value";     }     console.log(requesturi);     $ .ajax           ({               url: requesturi,             type: "GET",                headers:               {                   "accept": "application/json;odata=verbose",                   "content-type": "application/json;odata=verbose",             },               cache: false,               success: function(data)                {                   console.log('success');                 console.log(data.d.results[0].Title);                              },               error: function(data)               {                   console.log('error occured');               }           }); }    </script> 

Below is output screenshot when I hover on data or add it in console:

Can someone suggest me how can I get data in correct json output?
