I am experiencing issues with the HTTPClient call not returning accurate JSON data within my Appcelerator Titanium application

Every time I attempt to retrieve information from a JSON file, I encounter an error.

function search(e){
    var url = 'https://www.dotscancun.com/createjson.php?id=100001';
    var xhr = Ti.Network.HTTPClient({
        onerror: function(e){
            Ti.API.info(this.responseText);
            Ti.API.info(this.status);
	    Ti.API.info(e.error);
        },
	timeout: 5000
    });   
    xhr.open('GET',url);
    xhr.send();
    xhr.onload = function(){ 
	var json = JSON.parse(this.responseText); 
	alert(json);
    };
};

This is the code snippet causing the issue.

The specific error message reads as follows:

[LiveView] Client connected
[ERROR] :  TiHTTPClient: (TiHttpClient-8) [1340,1340] HTTP Error (java.io.IOException): 404 : Not Found
[ERROR] :  TiHTTPClient: java.io.IOException: 404 : Not Found
[ERROR] :  TiHTTPClient:    at ti.modules.titanium.network.TiHTTPClient$ClientRunnable.run(TiHTTPClient.java:1217)
[ERROR] :  TiHTTPClient:    at java.lang.Thread.run(Thread.java:818)

A 404 error indicates that the website does not exist. However, if you directly paste the URL into your browser, it works fine. What could be causing this discrepancy?

Answer №1

The error message mentioned in your query is not pertaining to the JSON query, but rather it is linked to the log output of your Android device. Therefore, you can safely overlook that particular call.

The reason for the coding mistake is as follows:

  • You have not correctly created an HTTPClient object. Instead of using Ti.Network.HTTPClient, you should utilize Ti.Network.createHTTPClient.
  • The onload method must be defined before the open() call.

Below is the accurate code snippet for your inquiry:

function buscar(e){
    var url = 'https://www.dotscancun.com/createjson.php?id=100001';

    var xhr = Ti.Network.createHTTPClient({
        onerror: function(e){
            Ti.API.info(this.responseText);
            Ti.API.info(this.status);
            Ti.API.info(e.error);
        },

        timeout: 5000,

        onload : function(){
            alert(this.responseText);

            // Parse the response for future utilization
            var tempJSON = JSON.parse(this.responseText);
        }
    });

    xhr.open('GET',url);
    xhr.send();
}
