Question

这个问题与YQL / datatables.org相关的问题是不，有些人声称要在几天前失败，因为YQL在我的案例中做了回应，但问题在于回应字符集，因此解码它。对于像GOOG这样的其他安全标志，过去它的反应非常好。

这是我用来从Yahoo finance API检索“AOJ-P.CO”的股票数据的REST查询：

https://query.yahooapis.com/v1/public/yql?q=select%20*%20from%20yahoo.finance.quote%20where%20symbol%20in%20(%22AOJ-P.CO%22)&format=json&diagnostics=true&env=store%3A%2F%2Fdatatables.org%2Falltableswithkeys&callback=

它给出了以下回应：

基本上要注意这一点：

   ],

它表示“无法使用utf-8解码响应内容”

我不确定这里有什么问题，但这是一个有效的股票代码，应该给出如下结果： https://in.finance.yahoo.com/quote/AOJ-P.CO?p=AOJ-P.CO

猜测是因为响应中有一些特殊的字符，比如它的名字“BrødreneA＆amp; O Johansen A / S”？

但它在响应中提到的quotes.csv中给出了一些结果： http://download.finance.yahoo.com/d/quotes.csv?f=aa2bb2b3b4cc1c3c4c6c8dd1d2ee1e7e8e9ghjkg1g3g4g5g6ii5j1j3j4j5j6k1k2k4k5ll1l2l3mm2m3m4m5m6m7m8nn4opp1p2p5p6qrr1r2r5r6r7ss1s7t1t7t8vv1v7ww1w4xy&s=AOJ-P.CO

但是，如何才能像其他符号（例如“GOOG”）获得此符号的有效回复？这个请求有什么问题？

Answer 1

在我得到另一个解决方案之前，我发现最好暂时从响应中读取quotes.csv。

这是一个有用的库： https://github.com/dirkolbrich/yahoo-finance-query

YQL警告“无法解码响应内容”
