FlinkTransformation operator
After the data source reads the data, we can use various conversion operators to convert one or more DataStreams into new DataStreams. After the data source enters, we can convert the data source into the data format we need according to a series of transformation operators, and then output it. Basic conversion operators (map/ filter/ […]
For interface automation testing, you must master these four methods of post submission data.
We all know that POST is generally used to submit data to the server. The four formats of POST submitted data are the four forms of Content-Type. Pay special attention to the format of the data in the body when http sends a request in each format. The 4 forms are: 1. application/x-www-form-urlencoded: URL encoded. […]
[Data processing] python Matplotlib partially enlarges the figure; marks the local enlarged subfigure of interest
Foreword In data visualization, it is often necessary to partially enlarge the data in a certain interval to obtain a higher contrast visualization effect. The following uses the Matplotlib library of the Python language to implement a simple partial magnification effect. Dependent libraries matplotlib: plotting library numpy: an extended library that supports a large number […]

Python generates a pair of RSA keys and saves the public and private keys as .pem files respectively. Use the public key in the generated RSA key pair to encrypt the data, and then use the private key to decrypt. Convert RSA’s public key exponent (E) and modulus (N) to .pem format
You can use the cryptography library to generate a pair of RSA keys and save the public and private keys as .pem files respectively. Here is a sample code: from cryptography.hazmat.backends import default_backend from cryptography.hazmat.primitives import serialization from cryptography.hazmat.primitives.asymmetric import rsa # Generate RSA key pair private_key = rsa.generate_private_key( public_exponent=65537, key_size=2048, backend=default_backend() ) # Get […]
