使用 CaptchaAI 构建客户端验证码管道

当您管理多个客户的抓取或自动化时，每个项目最终都会遇到验证码。不要为每个项目编写一次性的解决代码，而是构建一个可重用的管道。本指南将介绍该架构。

管道架构

┌──────────────┐    ┌───────────────┐    ┌──────────────┐
│  Client A    │──▶ │               │    │              │

│  Client C    │──▶ │               │    │  API         │

                    ┌───────────────┐    ┌──────────────┐
                    │  Result Store │◀── │  Polling      │

                    └───────────────┘    └──────────────┘

成分：

1. 任务接收 - 接收来自客户端抓取工具的解决请求
2. 队列 - 缓冲任务，强制每个客户端的并发限制
3. 求解器工作人员 – 提交至 CaptchaAI 并投票获取结果
4. 结果存储 - 保存已解决的令牌以供消费者检索

多客户端使用

pipeline = CaptchaPipeline(api_key="YOUR_API_KEY", max_concurrent=15)

# Client A — reCAPTCHA v2
pipeline.enqueue(SolveRequest(
    client_id="client_a",
    method="userrecaptcha",
    params={
        "googlekey": "6Le-SITEKEY-A",
        "pageurl": "https://client-a-staging.example.com/qa-form"
    },
    callback=lambda r: print(f"[{r.client_id}] Solved: {r.token[:40]}...")
))

# Client B — Turnstile
pipeline.enqueue(SolveRequest(
    client_id="client_b",
    method="turnstile",
    params={
        "sitekey": "0x4AAAA-SITEKEY-B",
        "pageurl": "https://client-b-target.com/login"
    },
    callback=lambda r: print(f"[{r.client_id}] Solved: {r.token[:40]}...")
))

pipeline.process_queue()

Node.js 管道

const axios = require("axios");

const SUBMIT_URL = "https://ocr.captchaai.com/in.php";
const RESULT_URL = "https://ocr.captchaai.com/res.php";

class CaptchaPipeline {
  constructor(apiKey, maxConcurrent = 10) {
    this.apiKey = apiKey;
    this.maxConcurrent = maxConcurrent;
    this.queue = [];
    this.activeCount = 0;
  }

  enqueue(clientId, method, params) {
    return new Promise((resolve, reject) => {
      this.queue.push({ clientId, method, params, resolve, reject });
      this._processNext();
    });
  }

  async _processNext() {
    if (this.activeCount >= this.maxConcurrent || this.queue.length === 0) return;

    this.activeCount++;
    const task = this.queue.shift();

    try {
      const token = await this._solve(task);
      task.resolve({ clientId: task.clientId, token });
    } catch (err) {
      task.reject(err);
    } finally {
      this.activeCount--;
      this._processNext();
    }
  }

  async _solve(task) {
    const submitResp = await axios.post(SUBMIT_URL, null, {
      params: {
        key: this.apiKey,
        method: task.method,
        json: 1,
        ...task.params,
      },
      timeout: 15000,
    });

    if (submitResp.data.status !== 1) {
      throw new Error(submitResp.data.error_text || submitResp.data.request);
    }

    const taskId = submitResp.data.request;
    return this._poll(taskId);
  }

  async _poll(taskId, maxWait = 120000) {
    const interval = 5000;
    let elapsed = 0;

    while (elapsed < maxWait) {
      await new Promise((r) => setTimeout(r, interval));
      elapsed += interval;

      try {
        const resp = await axios.get(RESULT_URL, {
          params: {
            key: this.apiKey,
            action: "get",
            id: taskId,
            json: 1,
          },
          timeout: 10000,
        });

        if (resp.data.status === 1) return resp.data.request;
        if (resp.data.request !== "CAPCHA_NOT_READY") {
          throw new Error(resp.data.error_text || resp.data.request);
        }
      } catch (err) {
        if (err.response) throw err;
      }
    }

    throw new Error(`Timeout waiting for task ${taskId}`);
  }
}

// Usage
(async () => {
  const pipeline = new CaptchaPipeline("YOUR_API_KEY", 15);

  const results = await Promise.allSettled([
    pipeline.enqueue("client_a", "userrecaptcha", {
      googlekey: "6Le-SITEKEY-A",
      pageurl: "https://client-a-staging.example.com/qa-form",
    }),
    pipeline.enqueue("client_b", "turnstile", {
      sitekey: "0x4AAAA-SITEKEY-B",
      pageurl: "https://client-b-target.com/login",
    }),
  ]);

  results.forEach((r) => {
    if (r.status === "fulfilled") {
      console.log(`[${r.value.clientId}] Token: ${r.value.token.slice(0, 40)}...`);
    } else {
      console.error(`Failed: ${r.reason.message}`);
    }
  });
})();

每个客户端配置

跟踪每个客户端的设置，例如代理、求解器首选项和速率限制：

CLIENT_CONFIG = {
    "client_a": {
        "proxy": "host:port:user:pass",
        "proxytype": "HTTP",
        "max_concurrent": 5,
        "default_method": "userrecaptcha"
    },
    "client_b": {
        "proxy": None,
        "proxytype": None,
        "max_concurrent": 10,
        "default_method": "turnstile"
    }
}

def build_params(client_id, params):
    config = CLIENT_CONFIG.get(client_id, {})
    if config.get("proxy"):
        params["proxy"] = config["proxy"]
        params["proxytype"] = config["proxytype"]
    return params

错误处理策略

故障排除

常问问题

每个客户端应该运行多少个并发任务？

从 5-10 开始。监控解决时间和错误率，然后进行调整。CaptchaAI 支持高并发，但您的代理池可能是瓶颈。

我应该为每个客户端使用单独的 API 密钥吗？

它简化了计费。如果需要一键跟踪，请使用 CaptchaAI soft_id 参数。

如何处理通宵排队的情况？

持久化队列（Redis 或数据库）。重新启动时，重新加载挂起的任务并恢复处理。
