httptools

0.7.1 · active · verified Sat Apr 11

A Python binding for the Node.js HTTP parser, providing fast and efficient HTTP parsing capabilities. Current version: 0.7.1. Maintained actively with regular updates.

Common errors

```
ModuleNotFoundError: No module named 'httptools'
```
cause The `httptools` library is not installed in the Python environment where the code is being run.

fix Install the library using pip: `pip install httptools`
```
ERROR: Failed building wheel for httptools
```
cause This error typically occurs during installation, especially on Windows, because `httptools` is a C extension and requires a C++ compiler (like Microsoft Visual C++ Build Tools) to build from source if a pre-built wheel is not available for your specific Python version and operating system.

fix Ensure you have the necessary C++ build tools installed (e.g., Microsoft Visual C++ Build Tools on Windows). Alternatively, try installing within a virtual environment or using a package manager like conda: `conda install -c conda-forge httptools`
```
TypeError: 'str' does not have the buffer interface
```
cause This error can occur when `httptools` parser methods, such as `feed_data`, expect byte-like objects but receive a string instead.

fix Ensure that the data being fed to `httptools` parser methods is a byte string (e.g., `b'GET / HTTP/1.1\r\n\r\n'`) rather than a regular string.
```
httptools.HttpParserInvalidURLError
```
cause This error indicates that the HTTP parser encountered a malformed or invalid URL within the HTTP request or response it was trying to process.

fix Validate the incoming HTTP request or response data, specifically the URL, to ensure it conforms to HTTP specifications before passing it to the `httptools` parser.

Warnings

breaking Python 3.8 is no longer supported; Python 3.9 or higher is required.
Fix: Upgrade to Python 3.9 or later.
breaking The 'protocol' object passed to HttpRequestParser must be defined and then have the required methods implemented.
Fix: Ensure the 'protocol' object is defined and instantiated before being passed to HttpRequestParser, and that it implements all necessary methods as per httptools documentation.
breaking The 'protocol' variable is not defined before being passed to HttpRequestParser.
Fix: Define and initialize the 'protocol' object before passing it to HttpRequestParser.

Install

pip install httptools Install httptools

Imports

HttpRequestParser
```
from httptools import HttpRequestParser
```
Ensure correct import path to access the HttpRequestParser class.

Quickstart

A basic example demonstrating how to import and use the HttpRequestParser class from httptools.

from httptools import HttpRequestParser

# Initialize the parser with a protocol object
parser = HttpRequestParser(protocol)

# Feed data to the parser
parser.feed(data)

# Access parsed data
parsed_data = parser.get_parsed_data()
