看了两天正则表达式，总算是看完了也算入门了吧，顺便把python 15章的习题也给一并清了。 以下是个人的答案，若有不当之处请指教 #coding=utf-8 #!/bin/env python import re #1. 识别下列字符串：“bat,” “bit,” “but,” “hat,” “hit,” 或 “hut” def test1(): bt='bat|bit|but|hat|hit|hut' inputstr=raw_input('input needs to match String') m=re.match(bt,inputstr) if m is not None:print(m.group()) else:print 'not match' # test1() #2.匹配用一个空格分隔的任意一对单词，比如，名和姓 def test2(): bt='(.*)\s(.*)' inputstr=raw_input('输入您的姓名，姓与名之间用空格隔开\n') m=re.match(bt,inputstr) if m is not None: print('您的姓是:%s'%m.group(1)) print('您的名是:%s'%m.group(2)) print('all is:%s'%m.group(0)) else:print 'not match' #

when I try to login to my database with psql, doing this: psql dbname --username=qgis --password >>(prompts for password, entered password) psql: FATAL: permission denied for database "gisdatabase" DETAIL: User does not have CONNECT privilege. I've searched around on Google for information on this simple issue but haven't found anyone directly talking about this. I've tried doing this: psql dbname >>ALTER ROLE qgis WITH CONNECT; But got this error: ERROR: unrecognized role option "connect" So once again, here I am, asking yet another question on stackoverflow. Thanks for your time folks You

I am only just learning about custom taxonomies for Wordpress. How is it possible to restrict access for my users to use a taxonomy. For instance, I have created a taxonomy named featured and I only want Editors and above roles to be able to add posts to this taxonomy. How do I set the access level? Either based on user role or capability, both works for me. Here is the code that I use for my taxonomy: function add_custom_taxonomies() { // Add new "Featured" taxonomy to Posts register_taxonomy('featured', 'post', array( // Hierarchical taxonomy (like categories) 'hierarchical' => true, // This

目录 什么是对象？什么是类？ 对象就是变量 类时一系列对象相同的特征与技能的结合体 绑定方法的有什么特点 对象的绑定方法，是由对象来调用的，特殊之处就是把对象当做第一个参数传入该方法中 基于面向对象设计一个对战游戏 基础的枪械游戏： class Saisi: def __init__(self,name,shooting1,life): #对象的所有特征 self.name = name self.shooting1 = shooting1 self.life = life #枪击的role方法 def shooting(self, role): if role.life <= 0: return True if self.life: #role掉血 role.life -= self.shooting1 print( f''' Saisi：[{self.name}]击中Role：[{role.name}] role掉血：[{self.shooting1}] role还剩血量：[{role.life}] ''') class Role: def __init__(self, name,shooting1, life): self.name = name self.shooting1 = shooting1 self.life = life #role枪击saisi方法 def

{ identities: [ // 以下几项自动编号为[0,1,2] { role: { name: "member", mspId: "peerOrg1" }}, { role: { name: "member", mspId: "peerOrg2" }}, { role: { name: "admin", mspId: "ordererOrg" }} ], policy: { // n-of 指定需要组内多少个进行签名， 1-of 等价于 OR, max-of 等价于AND，此处2与后面的组相同，因此是AND "2-of": [ // 对应编号2的身份 { "signed-by": 2}, // 嵌套 { "1-of": [{ "signed-by": 0 }, { "signed-by": 1 }]} ] } }Java中创建如下 .yaml 文件，并调用 ChaincodeEndorsementPolicy.fromYamlFile() 进行解析即可。示例策略对应命令行的 ：OR(OR('Org1MSP.member', 'Org1MSP.admin'), OR('Org2MSP.member', 'Org2MSP.admin')) 指定策略中会用到的角色 identities: # Org1MSP 中的 member user1: {"role": {"name":

I'm new to Chef and have been using Test Kitchen to test the validity of my cookbooks, which works great. Now I'm trying to ensure that environment-specific attributes are correct on production nodes prior to running Chef initially. These would be defined in a role. For example, I may have recipes that converge using a Vagrant box with dev settings, which validates the cookbook. I want to be able to test that a production node's role. I think I want these tests as the source of truth describing my environment. Looking at Test Kitchen's documentation, this seems beyond its scope. Is my

I am using the spring-security-core plugin in my grails app. I need to know the current user's role in a controller action. How can I retrieve that? Mike Sickler You can inject springSecurityService into your controller: def springSecurityService and then in your action, call: def roles = springSecurityService.getPrincipal().getAuthorities() See the docs here . From a controller you can use two methods the plugin adds to the metaclass, getPrincipal and isLoggedIn : def myAction = { if (loggedIn) { // will be a List of String def roleNames = principal.authorities*.authority } } If the action is

I installed PostgreSQL 9 database (migration from Oracle10g) and I am realy confused by user/role management. When I create new user using SQL command like CREATE USER or CREATE ROLE , or by Navicat tool, created user can see all databases! He realy can connect them! Although he can't select any data from table, he can see table objects and sequences and so on. I was trying revoke connect privilegia but no effect. I was expected the new user has no privilegia and cant see anything. I really don't know why he can. Lekensteyn From http://www.postgresql.org/docs/9.2/static/sql-grant.html#SQL
