AmazonCaptcha is a Go library that provides a simple and easy-to-use API for solving text captchas used by Amazon. This library simplifies the process of captcha resolution and enables fast integration into your applications, making it a powerful tool for your development needs.
To use this library, you need to have Go installed on your system. You can then install it using the following command:
go get github.com/gopkg-dev/amazoncaptcha
Using this library is simple:
package main
import (
"fmt"
"github.com/gopkg-dev/amazoncaptcha"
)
func main() {
//result, err := amazoncaptcha.Solve()
//result, err := amazoncaptcha.SolveFromURL("<URL>")
result, err := amazoncaptcha.SolveFromImageFile("captcha.jpg")
if err != nil {
fmt.Printf("Error solving captcha: %v", err)
return
}
fmt.Printf("Captcha solution: %s\n", result)
}
In this example, we load a captcha image from a file ("captcha.jpg"
) and solve it using the default solver provided by this library. The result is printed to the console.
This library also includes a custom training tool for solving simple captchas. Our tool is designed to simplify the process of training machine learning models for captcha solving, by automating the collection and extraction of relevant features from large datasets.
With our training tool, you can:
- Automatically collect large volumes of captcha images from multiple sources
- Extract and preprocess relevant features from these images
- Train and optimize your own machine learning models
By using this tool, you can quickly create custom captcha solvers optimized for your specific use case.
Note: The use of our tool to exploit or misuse captchas in any way may be against the terms of service of websites that use them, and is not endorsed by this library or its developers.
This project provides a set of tests to solve Amazon CAPTCHA problems. It includes the following tests:
TestDownloadCaptchaImages
: Downloads CAPTCHAs from the Amazon CAPTCHA service and saves them to disk if the letters haven't appeared in the dataset before.TestSplitAndSaveCaptchaByLetter
: Splits multiple Amazon CAPTCHAs stored in a directory into individual letters and saves them to separate directories for subsequent machine learning modeling.TestExtractFeatures
: Calculates image features for each letter extracted from split images, then saves those features to JSON files for further use.TestSolveBatch
: Performs batch testing on multiple Amazon CAPTCHAs stored in a directory. Each CAPTCHA is solved using theSolve
function and compared against the expected answer to determine its accuracy.TestSolveFromImageFile
: Tests theSolveFromImageFile
function by creating a temporary test image file, using the function to process the image, and checking the returned result for correctness.TestSolveFromURL
: Tests theSolveFromURL
function by using a mock HTTP server, which serves test data from a URL. The function is then used to process the data from the URL, and the returned result is checked for correctness.
Please refer to the amazoncaptcha_test.go file for the actual test implementations.
