HTTP Mock Server for Integration Tests

本目录包å<EFBFBD>«ç”¨äº?HttpdnsNWHTTPClient 集æˆ<C3A6>测试çš?HTTP/HTTPS mock server，用于替ä»?httpbin.orgã€?

为什么需�Mock Server�

1. **å<>¯é<C2AF> æ€?*: httpbin.org 在高并å<C2B6>‘测试下表现ä¸<C3A4>稳定，ç»<C3A7>常返回é<C5BE>žé¢„期çš?HTTP 状æ€<C3A6>ç <C3A7>（如 429 Too Many Requestsï¼?
2. 速度: 本地æœ<C3A6>务器å“<C3A5>应更快，缩短测试执行时间
3. 离线测试: 无需网络连接å<C2A5>³å<C2B3>¯è¿<C3A8>行集æˆ<C3A6>测试
4. **å<>¯æŽ§æ€?*: 完全掌控测试环境，便于调试和å¤<C3A5>现问题

支æŒ<EFBFBD>çš?Endpoints

Mock server 实现了以�httpbin.org 兼容�endpoints:

故障排除

端å<EFBFBD>£å·²è¢«å<EFBFBD> ç”¨

错误信æ<EFBFBD>¯:

âœ?端å<C2AF>£ 80 已被å<C2AB> ç”¨ï¼Œè¯·å…³é—­å<C2AD> ç”¨ç«¯å<C2AF>£çš„进程或使用其他端å<C2AF>£

解决方法:

1. 查找å<EFBFBD> ç”¨è¿›ç¨‹:

sudo lsof -i :80
sudo lsof -i :443

2. 终止å<EFBFBD> ç”¨è¿›ç¨‹:

sudo kill -9 <PID>

3. 或修æ”?mock_server.py 使用其他端å<C2AF>£:

# 修改端å<C2AF>£å<C2A3>·ï¼ˆå<CB86>Œæ—¶éœ€è¦<C3A8>更新测试代ç <C3A7>中çš?URLï¼?

缺少 OpenSSL

错误信æ<EFBFBD>¯:

�未找�openssl 命令，请安装 OpenSSL

解决方法:

# macOS (通常已预�
brew install openssl

# Ubuntu/Debian
sudo apt-get install openssl

# CentOS/RHEL
sudo yum install openssl

æ<EFBFBD>ƒé™<EFBFBD>被拒ç»?

错误信æ<EFBFBD>¯:

âœ?错误: 需è¦?root æ<>ƒé™<C3A9>以绑å®?80/443 端å<C2AF>£

解决方法:

必须使用 sudo è¿<C3A8>è¡Œ:

sudo python3 mock_server.py

切æ<EFBFBD>¢å›?httpbin.org

如需使用真实çš?httpbin.org 进行测试（例如验è¯<C3A8>兼容性）:

1. 编辑 HttpdnsNWHTTPClientIntegrationTests.m
2. 将所æœ?127.0.0.1 替æ<C2BF>¢å›?httpbin.org
3. 注释æŽ?setUp/tearDown 中的环境å<C692>˜é‡<C3A9>设置

å¼€å<EFBFBD>‘与扩展

添加�Endpoint

åœ?mock_server.py çš?MockHTTPHandler.do_GET() 方法中添åŠ?

def do_GET(self):
    path = urlparse(self.path).path

    if path == '/your-new-endpoint':
        self._handle_your_endpoint()
    # ... 其他 endpoints

def _handle_your_endpoint(self):
    """处ç<E2809E>†è‡ªå®šä¹?endpoint"""
    data = {'custom': 'data'}
    self._send_json(200, data)

调试模å¼<EFBFBD>

å<EFBFBD>–消注释 log_message 方法以å<C2A5>¯ç”¨è¯¦ç»†æ—¥å¿?

def log_message(self, format, *args):
    print(f"[{self.address_string()}] {format % args}")
