- 安装所需依赖
在 Haxe 中,我们需要使用以下库:
hxhttp:用于发送 HTTP 请求,下载验证码图片。
HaxePunk 或 OpenFL:用于图像处理和加载。
首先,确保你已经安装了 Haxe 和 Haxelib。在终端中可以使用以下命令安装依赖:
bash
haxelib install hxhttp
haxelib install openfl
2. 下载验证码图片
使用 Haxe 的 hxhttp 库发送 HTTP 请求下载验证码图片并保存到本地:
haxe
import hxhttp.Http;
import sys.io.File;
class Main {
static function main() {
var url = "https://captcha7.scrape.center/captcha.png";
var savePath = "captcha.png";
downloadCaptcha(url, savePath);
}
static function downloadCaptcha(url:String, savePath:String) {
Http.get(url, function(response) {
File.write(savePath, response.data);
trace("验证码图片已保存为 " + savePath);
});
}
}
3. 图像处理和 OCR 识别
接下来,我们使用 OpenFL 库加载验证码图片并调用 Tesseract 进行识别:
haxe
import openfl.display.Bitmap;
import openfl.display.BitmapData;
import openfl.Lib;
import openfl.utils.Assets;
class Main {
static function main() {
var imagePath = "captcha.png";
var processedPath = "captcha_processed.png";
preprocessImage(imagePath, processedPath);
var captchaText = recognizeCaptcha(processedPath);
trace("识别结果: " + captchaText);
}
static function preprocessImage(inputPath:String, outputPath:String) {
var img = Assets.getBitmapData(inputPath);
var grayBitmap = new BitmapData(img.width, img.height);
// 将图像转换为灰度
for (y in 0...img.height) {
for (x in 0...img.width) {
var color = img.getPixel(x, y);
var gray = (color.red * 0.299 + color.green * 0.587 + color.blue * 0.114);
grayBitmap.setPixel(x, y, gray);
}
}
grayBitmap.save(outputPath);
trace("处理后的验证码图片已保存为 " + outputPath);
}
static function recognizeCaptcha(imagePath:String):String {
var result = Sys.exec("tesseract " + imagePath + " stdout");
return result.output;
}
}
4. 自动化登录
最后,使用 hxhttp 发送 POST 请求,模拟登录操作,并传递用户名、密码和识别出的验证码:
haxe
class Main {
static function main() {
var username = "admin";
var password = "admin";
var captchaText = recognizeCaptcha("captcha_processed.png");
login(username, password, captchaText);

static function login(username:String, password:String, captcha:String) {
var url = "https://captcha7.scrape.center/login";
var data = { "username": username, "password": password, "captcha": captcha.trim() };
Http.post(url, data, function(response) {
if (response.status == 200) {
trace("登录成功");
} else {
trace("登录失败");
}
});
}
}
