问题 I have a angular application which works fine locally, but when published it on a test server it doesn't work any more some of my POST requests returns a 400 - bad request, and some don't, I have no idea why this is working locally but once published it doesn't.

POSTing to https form not always working

阅读更多关于 POSTing to https form not always working

问题 On my site I have a simple login form. The page is served via HTTP, but the form's POST URL is HTTPS. The normal method is that the user fills in their username/password, the form is submitted (to the fully qualified HTTPS URL, on the same site), and then the POST processing does a 303 redirect to the users' homepage. But sometimes this doesn't happen. The cycle (and this is 100% repeatable) is this: Visit login form, fill in details and submit On the server the login script gets called,

Django的请求生命周期

1. 概述首先我们知道HTTP请求及服务端响应中传输的所有数据都是字符串. 在Django中,当我们访问一个的url时,会通过路由匹配进入相应的html网页中. Django的请求生命周期是指当用户在浏览器上输入url到用户看到网页的这个时间段内,Django后台所发生的事情而Django的生命周期内到底发生了什么呢?? 1. 当用户在浏览器中输入url时,浏览器会生成请求头和请求体发给服务端请求头和请求体中会包含浏览器的动作(action),这个动作通常为get或者post,体现在url之中. 2. url经过Django中的wsgi,再经过Django的中间件,最后url到过路由映射表,在路由中一条一条进行匹配, 一旦其中一条匹配成功就执行对应的视图函数,后面的路由就不再继续匹配了. 3. 视图函数根据客户端的请求查询相应的数据.返回给Django,然后Django把客户端想要的数据做为一个字符串返回给客户端. 4. 客户端浏览器接收到返回的数据,经过渲染后显示给用户. 视图函数根据客户端的请求查询相应的数据后.如果同时有多个客户端同时发送不同的url到服务端请求数据服务端查询到数据后,怎么知道要把哪些数据返回给哪个客户端呢?? 因此客户端发到服务端的url中还必须要包含所要请求的数据信息等内容. 例如, http://www.aaa.com/index/?nid

Django—views系统：views基础

阅读更多关于 Django—views系统：views基础

Django的View（视图）简介一个视图函数（类），简称视图，是一个简单的Python 函数（类），它接受Web请求并且返回Web响应。响应可以是一张网页的HTML内容，一个重定向，一个404错误，一个XML文档，或者一张图片。无论视图本身包含什么逻辑，都要返回响应。代码写在哪里也无所谓，只要它在你当前项目目录下面。除此之外没有更多的要求了——可以说“没有什么神奇的地方”。为了将代码放在某处，大家约定成俗将视图放置在项目（project）或应用程序（app）目录中的名为 views.py 的文件中。一个简单的视图下面是一个以HTML文档的形式返回当前日期和时间的视图： from django.http import HttpResponse import datetime def current_datetime(request): now = datetime.datetime.now() html = "<html><body>It is now %s.</body></html>" % now return HttpResponse(html) 　　让我们来逐行解释下上面的代码：首先，我们从 django.http 模块导入了 HttpResponse 类，以及Python的 datetime 库。接着，我们定义了 current_datetime
