Sachin Singh · Answer

suppose your appsettings.json file is like below { "Logging" : { "LogLevel" : { "Default" : "Information" , "Warning" : "Warning" , "Error" : "Error" } }, "AllowedHosts" : "*" , "key" : "yourkey" } Now, to read the key create one method public class ConfigurationController : Controller { private readonly IConfiguration _config; public ConfigurationController(IConfiguration config) { _config = config; } // GET: api/Configuration [HttpGet] public string Get() { var result = _config.GetValue ( "key" ); return result }; } } now, you can call this method to get the key from jquery (ajax).

Hi, You can read appsettings.json file and read the data using javascript. function readTextFile(file, callback) { var rawFile = new XMLHttpRequest(); rawFile.overrideMimeType( "application/json" ); rawFile.open( "GET" , file, true ); rawFile.onreadystatechange = function () { if (rawFile.readyState === 4 && rawFile.status == "200" ) { callback(rawFile.responseText); } } rawFile.send( null ); } //change path of your appsettings.json file readTextFile( "./appsettings.json" , function (text){ var data = JSON.parse(text); console.log(data); });
