解析雅虎财经返回的 CSV 数据 API

Question

我想解析 Yahoo Finance API 返回的 CSV 格式的数据。我想要 company name: stock price 格式的输出。我已经下载了 Yahoo API 例子，代码如下：

String[] symbols = new String[] {"INTC", "BABA", "TSLA", "AIR.PA", "YHOO"};
Map<String, Stock> stocks = YahooFinance.get(symbols);

输出：

我只想要那家公司的价格

Answer 1

尝试这样的事情

import csv
import StringIO

raw_file = StringIO.StringIO("data1, data2, data3, ...")
reader = csv.reader(raw_file)
for FIELD1, FIELD2,FIELD3,FIELD4 in reader:
   print FIELD2

Answer 2

您显示的输出是 API 的日志记录。

您的 stocks 变量中提供了所有请求的 Stock 对象。如果你想打印每一个的价格，你应该这样做：

String[] symbols = new String[] {"INTC", "BABA", "TSLA", "AIR.PA", "YHOO"};
Map<String, Stock> stocks = YahooFinance.get(symbols); 

for(Stock s : stocks.values()) {
    System.out.println(s.getName() + ": " + s.getQuote().getPrice());
}

查看 javadoc 以查看 API 中可用的对象和方法。
