如何监控PostgreSQL存储过程/函数代码运行？本文介绍用python+微信/邮件的方式进行报警、监控。首先要有一张表、用于存放PostgreSQL存储过程/函数代码运行异常的信息。处理原则：若出现异常；把“发生时间+所在的程序+原因”通过微信/邮件发给对应人员。当然发送一次即可；起到通知的效果。一、媒介通过什么方式进行发送内容；下面介绍微信/邮件两种方式1、python发送微信py_wechar.py的内容企业微信号；大家可以到企业微信上配置#...

1. post请求方式编码有3种：application/x-www-form-urlencoded #最常见的post提交数据的方式，以form表单形式提交数据 application/json #以json格式提交数据 multipart/form-data #一般使用来上传文件（较少用） 2. post一贯的用法是：requests.post(url,data), 具体我们使用不同的编码方式来有所不同： 1）、传统表单post请求（x-www-form-urlencoded）import requests,jsonurl = ‘http://httpbin.org/post‘ data =...
Given an n-ary tree, return the postorder traversal of its nodes‘ values. For example, given a 3-ary tree: Return its postorder traversal as: [5,6,3,2,4,1].

暑假放假在家没什么事情做，所以在学习了爬虫，在这个博客园里整理记录一些学习的笔记。构建表单数据（以http://www.iqianyue.com/mypost 这个简单的网页为例）查看源代码，发现name属性值为“name”，密码对应的输入框中，name属性值为“pass”。因此构建表单的数据中要包含两个字段，字段名为“name”，“pass”，字段值设置成对应的需要传递的值。 格式为字典： {字段名1：字段值1，字段名2：字段值2，...} 下面是代...

解决办法：如请求参数为 data={“user”=“aaa”，“pwd”=“123456”，sign=“00000000000000”}需要将参数data先做处理，调用函数datas=datajson.dumps(datas,separators=(‘,‘,‘:‘))；然后在发送post请求request.post(url,datas,.....)': was expecting ('true', 'false' or 'null')”' ref='nofollow'>python中发送post请求时，报错“Unrecognized token 'xxxx': was expecting ('true', 'false' or 'null')”原文：https:/...
