本文实例分析了php进行支付宝开发中return_url和notify_url的区别。分享给大家供大家参考。具体分析如下:
在支付宝处理业务中return_url,notify_url是返回些什么状态呢,我们要根据它来做一些处理就必须了解return_url,notify_url的区别,下面我就来给大家介绍介绍.
问题描述:
我在处理支付宝业务中出现过这样的问题,付费完成后,在支付宝跳转到商家指定页面时,订单状态已经更新,通过调试发现是支付宝先通知notify_url,完成了订单状态.
支付宝return_url和notify_url通知顺序问题:
顺序不一定的,请别以先后顺序来做判断,具体如何判断,是根据您当前数据库里的状态和刚从支付宝里获取到的状态做对比来判断是否有做过处理了.
关于支付宝return_url和notify_url的区别,同步通知页面特性(return_url特性):
(1) 买家在支付成功后会看到一个支付宝提示交易成功的页面,该页面会停留几秒,然后会自动跳转回商户指定的同步通知页面(参数return_url);
(2) 该页面中获得参数的方式,需要使用GET方式获取,如request.QueryString("out_trade_no")、$_GET['out_trade_no'];
(3) 该方式仅仅在买家付款完成以后进行自动跳转,因此只会进行一次;
(4) 该方式不是支付宝主动去调用商户页面,而是支付宝的程序利用页面自动跳转的函数,使用户的当前页面自动跳转;
(5) 基于(4)的原因,可在本机而不是只能在服务器上进行调试;
(6) 返回URL只有一分钟的有效期,超过一分钟该链接地址会失效,验证则会失败;
(7) 设置页面跳转同步通知页面(return_url)的路径时,不要在页面文件的后面再加上自定义参数。例如:
错误的写法:
代码如下:
正确的写法:
代码如下:
服务器异步通知页面特性(notify_url特性):
(1) 必须保证服务器异步通知页面(notify_url)上无任何字符,如空格、HTML标签、开发系统自带抛出的异常提示信息等;
(2) 支付宝是用POST方式发送通知信息,因此该页面中获取参数的方式,如:
request.Form("out_trade_no")、$_POST['out_trade_no']。
(3) 支付宝主动发起通知,该方式才会被启用;
(4) 只有在支付宝的交易管理中存在该笔交易,且发生了交易状态的改变,支付宝才会通过该方式发起服务器通知(即时到账中交易状态为“等待买家付款”的状态默认是不会发送通知的);
(5) 服务器间的交互,不像页面跳转同步通知可以在页面上显示出来,这种交互方式是不可见的;
(6) 第一次交易状态改变(即时到账中此时交易状态是交易完成)时,不仅页面跳转同步通知页面会启用,而且服务器异步通知页面也会收到支付宝发来的处理结果通知;
(7) 程序执行完后必须打印输出“success”(不包含引号)。如果商户反馈给支付宝的字符不是success这7个字符,支付宝服务器会不断重发通知,直到超过24小时22分钟。
一般情况下,25小时以内完成8次通知(通知的间隔频率一般是:2m,10m,10m,1h,2h,6h,15h);
(8) 程序执行完成后,该页面不能执行页面跳转。如果执行页面跳转,支付宝会收不到success字符,会被支付宝服务器判定为该页面程序运行出现异常,而重发处理结果通知;
(9) cookies、session等在此页面会失效,即无法获取这些数据;
(10) 该方式的调试与运行必须在服务器上,即互联网上能访问;
(11) 该方式的作用主要防止订单丢失,即页面跳转同步通知没有处理订单更新,它则去处理;
(12) 通知ID(参数notify_id)只有一分钟有效期,超过一分钟该次通知会验证失败。一旦验证成功下次再验证就会失效。
希望本文所述对大家的php程序设计有所帮助。

What’s still popular is the ease of use, flexibility and a strong ecosystem. 1) Ease of use and simple syntax make it the first choice for beginners. 2) Closely integrated with web development, excellent interaction with HTTP requests and database. 3) The huge ecosystem provides a wealth of tools and libraries. 4) Active community and open source nature adapts them to new needs and technology trends.

PHP and Python are both high-level programming languages that are widely used in web development, data processing and automation tasks. 1.PHP is often used to build dynamic websites and content management systems, while Python is often used to build web frameworks and data science. 2.PHP uses echo to output content, Python uses print. 3. Both support object-oriented programming, but the syntax and keywords are different. 4. PHP supports weak type conversion, while Python is more stringent. 5. PHP performance optimization includes using OPcache and asynchronous programming, while Python uses cProfile and asynchronous programming.

PHP is mainly procedural programming, but also supports object-oriented programming (OOP); Python supports a variety of paradigms, including OOP, functional and procedural programming. PHP is suitable for web development, and Python is suitable for a variety of applications such as data analysis and machine learning.

PHP originated in 1994 and was developed by RasmusLerdorf. It was originally used to track website visitors and gradually evolved into a server-side scripting language and was widely used in web development. Python was developed by Guidovan Rossum in the late 1980s and was first released in 1991. It emphasizes code readability and simplicity, and is suitable for scientific computing, data analysis and other fields.

PHP is suitable for web development and rapid prototyping, and Python is suitable for data science and machine learning. 1.PHP is used for dynamic web development, with simple syntax and suitable for rapid development. 2. Python has concise syntax, is suitable for multiple fields, and has a strong library ecosystem.

PHP remains important in the modernization process because it supports a large number of websites and applications and adapts to development needs through frameworks. 1.PHP7 improves performance and introduces new features. 2. Modern frameworks such as Laravel, Symfony and CodeIgniter simplify development and improve code quality. 3. Performance optimization and best practices further improve application efficiency.

PHP type prompts to improve code quality and readability. 1) Scalar type tips: Since PHP7.0, basic data types are allowed to be specified in function parameters, such as int, float, etc. 2) Return type prompt: Ensure the consistency of the function return value type. 3) Union type prompt: Since PHP8.0, multiple types are allowed to be specified in function parameters or return values. 4) Nullable type prompt: Allows to include null values and handle functions that may return null values.

mPDF
mPDF is a PHP library that can generate PDF files from UTF-8 encoded HTML. The original author, Ian Back, wrote mPDF to output PDF files "on the fly" from his website and handle different languages. It is slower than original scripts like HTML2FPDF and produces larger files when using Unicode fonts, but supports CSS styles etc. and has a lot of enhancements. Supports almost all languages, including RTL (Arabic and Hebrew) and CJK (Chinese, Japanese and Korean). Supports nested block-level elements (such as P, DIV),
