WWW yield is not returning any value in ios for yahoo finance api

Hi All,

I am getting the stock value from yahoo finance and displaying it in a Text UI component. The below code is working fine in Windows PC, Mac, Android mobile but not in iOS.
Code is not getting executed after " yield return wwwEricA;" only for yahoo finance http link “http://finance.yahoo.com/d/quotes.csv?s=ERIC-A.ST&f=sl1d1t1c1p2ohgv&e=.csv” . For testing i have given “https://www.google.co.in/” and that is returning value in ios mobile also. So i guess the problem is only with that particular yahoo URL but could not find what is that. Please help me to solve this issue.

Code :

    public Text EricAStockText;

private WWW wwwEricA;
private string stockUrlEricA;
private string[] stockArrayEricA;
private char[] seperators = { ',' };

void Start()
	stockUrlEricA = "http://finance.yahoo.com/d/quotes.csv?s=" + WWW.EscapeURL("ERIC-A.ST&f=sl1d1t1c1p2ohgv&e=.csv");

private IEnumerator GetStockValueA(string URL)
        wwwEricA = new WWW(URL);
        yield return wwwEricA;

        stockArrayEricA = ParseStockValue(wwwEricA.text, seperator);
        EricAStockText.text = stockArrayEricA[1]; 

private string[] ParseStockValue(string valueString, char[] seperator)
        return valueString.Split(seperator, System.StringSplitOptions.RemoveEmptyEntries);

You use “EscapeURL” wrong. You escaped the “&” in your URL but you actually want them there. Your generated URL would look like this:


So your “equals” (=) and “ampersands” (&) are replaced with %26 and %3D. So the server only sees one parameter (“s”) which contains that rest as one string.

You should only exscape the content of your URL parameters.

stockUrlEricA = "http://finance.yahoo.com/d/quotes.csv?s=" + WWW.EscapeURL("ERIC-A.ST") + "&f=" + WWW.EscapeURL("sl1d1t1c1p2ohgv") + "&e=" + WWW.EscapeURL(".csv");

This would be the correct way to form your URL. However if you use a hardcoded URL you don’t need EscapeURL at all since your data don’t contain any problematic characters.

See URL Encoding for more details.

Yahoo finance API is not available anymore. I have moved to MarketXLS after this change, much more reliable data.
