Download and parse a JSON file
Hey!
I need to acces to a webservice; that returns me a JSON file…
The service is set on Force Download; so i think i must write in a file; then read it.
There is no result; so here's my code; if anyone can help me:
var xhr3 = Titanium.Network.createHTTPClient();
xhr3.onload = function()
{
var f=Titanium.Filesystem.getFile(Titanium.Filesystem.applicationDataDirectory,'temp.json');
f.write(this.responseData); // the response you get
var file=Titanium.Filesystem.getFile(Titanium.Filesystem.applicationDataDirectory, "temp.json");
if(file.exists()){
Ti.API.info('in file ' + file.nativePath);
var fcontent = file.read();
Ti.API.info('contents = ' + JSON.parse(fcontent.text));
}
};
xhr3.onerror = function()
{
Ti.API.info('in utf-8 error for POST');
};
xhr3.open("POST","adress");
xhr3.setRequestHeader("User-Agent", "App 1.0 (iPod touch; iPhone OS 3.1.3; fr_FR)");
var now = new Date();
var date = now.getYear() + '-' + now.getMonth() + '-' + now.getDate();
xhr3.send({"key":"key"});
The request have been tested; so it works.
Here's the Dbug
[INFO] in file /Users/name/Library/Application Support/iPhone Simulator/4.1/Applications/8500FA8B-5325-4BBD-98D7-1DCA60C84A7B/Documents/temp.json
[INFO] contents = null
It would be great to read directly the JSON file

Thanks for the answer; but here's the result:
[WARN] Exception in event callback. {
expressionBeginOffset = 1602;
expressionCaretOffset = 1631;
expressionEndOffset = 1644;
line = 70;
message = "Result of expression 'JSON.parse(this.responseText)' [null] is not an object.";
name = TypeError;
sourceId = 237605056;
sourceURL = "file://localhost/Users/name/dir/dir/dir/Resources/accueil.js";
}And I have no control on the webservice…
Thanks for your help!

What happens when you just try to POST to your JSON document's URL? In your onload handler, you should be able to say
var jsonObject = JSON.parse(this.responseText). -
Update:
With
var jsonObject = (this.responseData); Ti.API.info(jsonObject);I got
[INFO] [object TiBlob]
How can convert this to a string?
