The following two methods can be used to obtain stock data:
1. Data retrieval through HTTP/JavaScript Interfaces
2. Web-Service Interface
1. Data retrieval through HTTP/JavaScript Interfaces
1.1sina stock data interface
Take the Daqin Railway (stock code: 601006) as an example. To get its latest market, you only need to access Sina's stock data.
Interface:
Http://hq.sinajs.cn/list=sh601006
This URL returns a string of text, for example:
VaR hq_str_sh601006 = "Daqin railway, 27.55, 27.25, 26.91, 27.55, 26.20, 26.91, 26.92,
22114263,589 listen 680, 4695, 26.91, 57590, 26.90, 14700, 26.89, 14300,
26.88, 15100, 26.87, 3100, 26.92, 8900, 26.93, 14230, 26.94, 25150, 26.95, 15220, 26.96, 15:05:32 ";
This string is concatenated by many pieces of data. Data of different meanings are separated by commas. According to the programmer's idea, the sequence number starts from 0.
0: "Daqin Railway", stock name;
1: "27.55", available today;
2: "27.25", closing price yesterday;
3: "26.91", current price;
4: "27.55", the highest price today;
5: "26.20", the lowest price today;
6: "26.91", bidding price, that is, "buy one" quotation;
7: "26.92", competitive price, that is, "sell one" quotation;
8: "22114263". The number of votes in the transaction. Because the stock transaction uses one hundred shares as the basic unit, this value is usually divided by one hundred during use;
9: "589824680", deal amount, unit: "Yuan", in order to be clear, usually "10 thousand yuan" as the unit of deal amount, so usually divide the value;
10: "4695", "buy one" apply for 4695 shares, that is, 47;
11: "26.91", "buy one" quotation;
12: "57590", "Buy two"
13: "26.90", "Buy two"
14: "14700", "Buy three"
15: "26.89", "Buy three"
16: "14300", "Buy Four"
17: "26.88", "Buy Four"
18: "15100", "Buy five"
19: "26.87", "Buy five"
20: "3100", "sell one", declare 3100 shares, that is, 31 hands;
21: "26.92", "buy one" quotation
(22, 23), (24, 25), (26, 27), (28, 29) are the situations from "selling two" to "selling four" respectively"
30: "2008-01-11", date;
31: "15:05:32", time;
A simple JavaScript Application Example:
Script Type = "text/JavaScript" src = "http://hq.sinajs.cn/list=sh601006" charset = "gb2312">/SCRIPT>
/JavaScript ">
VaR elements = hq_str_sh601006.split (",");
Document. Write ("current price:" + elements [3]);
This code outputs the current stock price of Daqin Railway (stock code: 601006)
Current Price: 14.20
If you want to query multiple stocks at the same time, add a comma at the end of the URL and the stock code. For example, you need to query Daqin Railway (601006) and Datong coal (601001) at a time) the URL is used as follows:
Http://hq.sinajs.cn/list=sh601003,sh601001
Query the index of the dashboard, for example, the Shanghai Composite Index (000001 ):
Http://hq.sinajs.cn/list=s_sh000001
The data returned by the server is:
VaR hq_str_s_sh000001 = "Shanghai Stock Index, 3094.668,-128.073,-3.97, 436653,5458126 ";
The data meanings are: Index name, current points, current price, rise/fall rate, transaction volume (hand), and transaction amount (10 million RMB );
Query Shenzhen index:
Http://hq.sinajs.cn/list=s_sz399001
You can request http://image.sinajs.cn/… to obtain the K-line and daily-line charts of a stock /.... /... /*. GIF: This URL is obtained. * indicates the stock code. For details, see the following:
View the daily K-line chart:
Http://image.sinajs.cn/newchart/daily/n/sh601006.gif
Time-sharing line query:

1.2 Baidu & Google financial data
When you search for a stock code in Baidu or Google, information about the stock is displayed in the headlines. For example, when you search for 601006,
The first search result is as follows:
By clicking the picture on the left, we found that this picture will be linked to the Sina financial channel, that is, the acquisition of Google stock data is also obtained from Sina. After packet capture analysis, we found that Google also adopted the interface described in 1.1.
Baidu stock data comes from Baidu's financial channel
Http://stock.baidu.com/
1.3 Other Methods
In addition to Sina, Baidu and other websites that provide stock information, other websites also have similar interfaces. We analyzed a stock plug-in used on the Forum,
For details about how to obtain real-time stock data, see the following code. Some data is from Sina.
The following is an example of ASP:

Stockdata = gethttp ("http://hq.sinajs.cn/list=sh" & code &"")
If not Len (stockdata) = 0 then stockdata = Split (stockdata, CHR (34) (1)

The Web service method is similar to the current project's dbws data acquisition. It uses the SOAP protocol to obtain relevant data from the dbws server.
Use Yahoo to check Chinese shares
Http://quote.yahoo.com/d/quotes.csv? S = MSFT & F = slc1wop
Back to Microsoft's stock price
"MSFT", "4: 00 pm-
30.70", + 1.04," 21.46-30.75 ", 29.77, 29.66
Http://quote.yahoo.com/d/quotes.csv? S = 000969.sz& F = slc1wop
This is returned by Antai technology,
Generally, there is a latency of half an hour..
But the sz after S = 000969.sz is the meaning of Shenzhen, and Shanghai is the SS suffix.
