HttpClient返回錯誤的csv？

嗨我一直在試圖從http://download.finance.yahoo.com/d/quotes.csv?s=msft&f=sl1p2下載csv，並一直試圖隨後解析數據。以下是代碼。它目前只返回吐司中的html頭部。任何想法，爲什麼它不是在csv中返回實際結果？HttpClient返回錯誤的csv？

Stock stock = new Stock(); 
    try { 

     //need to call yahoo api and get csv -> parse csv for most recent price and price change 
     HttpClient httpClient = new DefaultHttpClient(); 
     HttpContext localContext = new BasicHttpContext(); 
     HttpGet httpGet = new HttpGet(uri); 
     HttpResponse response = httpClient.execute(httpGet, localContext); 
     String result = ""; 

     BufferedReader reader = new BufferedReader(new InputStreamReader(response.getEntity().getContent())); 

     String line = ""; 
     while ((line = reader.readLine()) != null){ 

       result += line + "\n"; 
       String[] RowData = result.split("\n"); 
       Toast.makeText(this, result, Toast.LENGTH_LONG).show(); 
       String name = RowData[0]; 
       String price = RowData[1]; 
       String change = RowData[2]; 

       stock.setPrice(Double.parseDouble(price)); 
       stock.setTicker(name); 
       stock.setChange(change); 


      }

難道你不需要以逗號而不是換行符來輸入split？

String[] RowData = result.split(",");

當我與

System.out.println("result = "+ result);

運行使用上述，並更換吐司的代碼我得到：

result = "MSFT",24.80,"+0.08%"

和name，price和change值被成功地填充。我根本看不到標題行。

請注意，Java約定是變量名以小寫字母開頭，所以rowData不是RowData。

是的，這是解決方案。弄明白了:)。我還需要使用replaceAll來擺脫引號。 – locoboy 2011-03-20 21:10:44

http://download.finance.yahoo.com/d/quotes.csv?s=msft&f=sl1p2

您提供的含有兩個參數的網址：

1: s=msft 
    -this is the yahoo finance api code for microsoft 

2: f=sl1p2 
    - this contains 3 sub-parameters 
    - s [it is the company name] 
    - l1 [it is the company's last quote price] 
    - p2 [it is the price change]

，所以我想你所得到的CSV是正確的。

是啊我不完全確定我要去哪裏錯了。 – locoboy 2011-03-20 18:14:40

我有一個相同的php代碼片段。如果你想，那麼我可以與你分享。 – 2011-03-20 18:18:28

當然我想看看 – locoboy 2011-03-20 18:55:27

<?php 

function getStockSite($stockLink){ 

    if ($fp = fopen($stockLink, 'r')) { 
     $content = ''; 

     while ($line = fread($fp, 1024)) { 
     $content .= $line; 
     } 
    } 

    return $content; 
} 

?>
