c# 与 PHP中 SHA1加密结果不同解决方法
那天在调试API的时候,发现用c#写的SHA1加密出来的结果和PHP中sha1()出来的不一样,找了半天的原因后来才弄出来
在调试微信接口的时候大多的帮助文档都是提供的是PHP的方法,所以在.net中实现的时候会出现很多的问题,最典型的就是token通不过验证
现在提供一个结果与Php一样 的SHA1方法
public static string Sha1Sign(string data) { byte[] temp1 = Encoding.UTF8.GetBytes(data); SHA1CryptoServiceProvider sha = new SHA1CryptoServiceProvider(); byte[] temp2 = sha.ComputeHash(temp1); sha.Clear(); // 注意, 不能用这个 // string output = Convert.ToBase64String(temp2);// 不能直接转换成base64string var output = BitConverter.ToString(temp2); output = output.Replace("-", ""); output = output.ToLower(); return output; }
解决方式:在php中sha1出来的是小写字母,可是在c#中默认出来的是大写,在token验证的时候也是区分大小写的,另外很多人在
// string output = Convert.ToBase64String(temp2);// 不能直接转换成base64string var output = BitConverter.ToString(temp2);
这里犯了错误却一直没有发现,所以找了很久的原因
PS:
在送上一个Php的
base64_encode的c#实现
public static string Base64_encode(string data) { return Convert.ToBase64String(Encoding.UTF8.GetBytes(data)); }

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),
