Question

我在Laravel 5.2中工作，我想访问控制器中的URL段。我正在使用

\b([a-oq-z]+|[a-oq-z]*(p[a-gi-z][a-oq-z]*)+)p?\b

但没有打印。如何从控制器中的url获取值。

Answer 1

在laravel 5.2中你可以这样做..

echo request()->segment(2);

request（）是Laravel 5.2中提供的几个辅助函数之一。它返回当前请求对象，因此您不需要在类顶部使用外观的使用语句。

Answer 2

在Laravel 7中，我正在使用它来获取细分

from pyspark.sql import Window, WindowSpec
import pyspark.sql.functions as F
import pandas as pd

# Create the test data Assuming everyday, we have data for all departments
date = ['2020-07-06', '2020-07-06', '2020-07-06', '2020-07-06','2020-07-07','2020-07-07','2020-07-07','2020-07-07', '2020-07-08', '2020-07-08','2020-07-08','2020-07-08' ]
dept = ['Marketing', 'Sales', 'Engg', 'Sites','Marketing', 'Sales', 'Engg', 'Sites','Marketing', 'Sales', 'Engg', 'Sites',]
rate = [20,15,40,18,20, 3, 6, 9, 100,5,10,7]
df = pd.DataFrame([date, dept, rate]).T
df.columns = ['date', 'dept', 'rate']

# create spark DtaFrame
sdf = spark.createDataFrame(df)

sdf.show()
