Cordova中的本地Web服务调用失败，结果为ERR_FILE_NOT_FOUND

Question

I am using ASP.Net and building an android app using Cordova 5.1.1. I have created the web service ( services.asmx ) which has a method appStatus and I am calling the same in index.html page. This works perfectly when I run or publish in my laptop. But once I build and run, I get the file not found error with status 0.

Ajax Call

        var request = $.ajax({
            url: "services.asmx/appStatus",
            method: "POST",
            data: {},
            dataType: "json",
            contentType: "application/json; charset=utf-8",
            success: ajaxSigninSuccess,
            error: ajaxSigninError
        });

        function ajaxSigninSuccess(response) {
            alert(response.d);
        }

        function ajaxSigninError(response) {
            alert(response.status + " " + response.statusText);
        }

Following is the response text

onabort: null
onerror: null
onload: null
onloadend: null
onloadstart: null
onprogress: null
onreadystatechange: null
ontimeout: null
readyState: 4
response: ""
responseText: ""
responseType: ""
responseURL: ""
responseXML: null
status: 0
statusText: ""
timeout: 0

Error

GET file:///android_asset/www/services.asmx/appStatus net::ERR_FILE_NOT_FOUND

Please help, thanks in advance.

You have problem about server + client side.
I call server is where your service ASP.Net ("services.asmx") deploy.
Client is your mobile app in device.

1. When your server + client in your computer.
Ex: url service: " http://localhost:8080/services.asmx " then when you call ajax by url 'services.asmx/appStatus' then it will get path of html file(include ajax code) and prepend to url. If html file is " http://localhost:8080/index.html " then url call by ajax will be: " http://localhost:8080/services.asmx/appStatus ". I think it working with you.

2. When server deploy in you computer and client running in device (emulator).
Ip address of your computer and emulator in your computer is different. Your app start with index.html file: "file:///android_asset/www/index.html" and so that url call by ajax will be: "file:///android_asset/www/services.asmx/appStatus" not found any service or file at url.

3. Solutions: call ajax by full url: " http://domain.com/services.asmx/appStatus " or if your server deploy in local then " http://ipaddress:port/services.asmx/appStatus ".
