本文实例讲述了ASP.NET利用第三方类库Newtonsoft.Json提取多层嵌套json数据的方法,具体例子如下. 假设需要提取的json字符串如下: {"name":"lily","age":23,"addr":{"city":guangzhou,"province":guangdong}} 先引用命名空间: using Newtonsoft.Json; using Newtons
{底背离,通达信版.同花顺版} DIFF:=EMA(CLOSE,) - EMA(CLOSE,); DEA:=EMA(DIFF,); MACD:=*(DIFF-DEA); QZQ:=BARSLAST(REF(MACD,)< AND MACD>); QM:=LLVBARS(MACD,QZQ+); MQDZ:=IF(QM>QZQ,REF(MACD,QM),); XG1:=MACD< AND MACD>MQDZ AND CLOSE=LLV(CLOSE,QZQ+) AND MQDZ&l
今天用 BW 标准数据源 0CO_PC_ACT_10 提取数据时,发现物料有一项数据[没有被分摊]无法取到. 根据SAP的解释,此项不在后台存数,通过前台动态生成. For the virtual cumulative inventory and for the Not Distributed line, there are no records in the database,which is why the extractor cannot extract them. In transact
在.net 2.0中提取这样的json {"name":"lily","age":23,"addr":{"city":guangzhou,"province":guangdong}} 引用命名空间 using Newtonsoft.Json; using Newtonsoft.Json.Linq; 可以把上面的JSON看成一个对象.你只要写对应的类即可 public class User
注:原文中的代码是在spark-shell中编写运行的,本人的是在eclipse中编写运行,所以结果输出形式可能会与这本书中的不太一样. 首先将用户数据u.data读入SparkContext中.然后输出第一条数据看看效果.代码例如以下: val sc = new SparkContext("local", "ExtractFeatures") val rawData = sc.textFile("F:\\ScalaWorkSpace\\data\\ml-
