There are many ways to record scripts in JMeter. The most common method is to use the third-party tool badboy to record. There are also JMeter's own settings (Http proxy server IE browser settings) to record scripts, but this method There are many and messy recorded scripts, which I personally don’t like. Generally, Badboy is used for recording. Here’s an introduction to Badbody recording.
Note: When using JMeter proxy or BadBoy for recording, especially when using JMeter proxy, the operation should not be too fast, otherwise the recording may fail.
Introduction to badboy:
- Badboy is a free WEB automated testing tool.
- Official download address: http://www.badboy.com.au
- The installation of badboy is the same as that of a general application. Badboy is a goodweb automation testing tool. Use it to record scripts, and the recorded scripts can be directly saved as JMeter files for use. . It has undoubtedly brought us great convenience.
1. Open the badboy tool and enter the address of the tested project in the address column
Note: badboy is in the recording state in normal state, which is a red button, as shown in the picture
After the recording is completed, click the black button next to the toolbar to end the recording.
2. Select "File" --Export to Jmeter...
3.Open the JMeter tool, select "File" --> "Open" select the file you just saved (.jmx type) and import the file. .
Be sure to add HTTP Cookie Manager to the recorded script, otherwise the script will fail to run. Remember.
Now for JMeter, a test plan can only have one cookie manager. Because when multiple Managers exist, JMeter currently has no way to specify which Manager to use. At the same time, cookies stored in a Cookie Manager cannot be referenced by other Cookie Managers, so it is not recommended to use multiple Cookies in the same test plan. Manager.
Adding cookies will ensure that each user uses a different cookie, but sharing an Http element, almost all web tests require cookie support.

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),

SecLists
SecLists is the ultimate security tester's companion. It is a collection of various types of lists that are frequently used during security assessments, all in one place. SecLists helps make security testing more efficient and productive by conveniently providing all the lists a security tester might need. List types include usernames, passwords, URLs, fuzzing payloads, sensitive data patterns, web shells, and more. The tester can simply pull this repository onto a new test machine and he will have access to every type of list he needs.
