Claude Code + Qwen 的配置方法

前言

由于 Claude Code 和 Qwen 的请求格式有点不兼容，需要另外写一个代理来确保正常地请求

使用代理拦截和修改请求

javascript 复制代码

const http = require('http');
const https = require('https');

const targetHost = 'dashscope.aliyuncs.com';
const targetPath = '/apps/anthropic/v1/messages';

const server = http.createServer((req, res) => {
    let body = '';
    req.on('data', chunk => { body += chunk; });
    req.on('end', () => {
        try {
            const originalReq = JSON.parse(body);
            // 修改 max_tokens
            if (originalReq.max_tokens > 8192) {
                originalReq.max_tokens = 8192;
            }
            // 确保 top_p 等参数也在范围内
            if (originalReq.top_p && originalReq.top_p > 1) {
                originalReq.top_p = 0.95;
            }
            
            const options = {
                hostname: targetHost,
                path: targetPath,
                method: 'POST',
                headers: {
                    ...req.headers,
                    'host': targetHost,
                    'content-length': Buffer.byteLength(JSON.stringify(originalReq))
                }
            };
            
            const proxyReq = https.request(options, (proxyRes) => {
                res.writeHead(proxyRes.statusCode, proxyRes.headers);
                proxyRes.pipe(res);
            });
            
            proxyReq.write(JSON.stringify(originalReq));
            proxyReq.end();
        } catch(e) {
            console.error('Proxy error:', e);
            res.writeHead(500);
            res.end('Proxy error');
        }
    });
});

server.listen(8080, () => {
    console.log('Proxy running on http://localhost:8080');
});

然后修改 settings.json：

json 复制代码

{
  "env": {
    "ANTHROPIC_AUTH_TOKEN": "你的apikey",
    "ANTHROPIC_BASE_URL": "http://localhost:8080",
    "ANTHROPIC_MODEL": "qwen-max"
  }
}

先用 node 运行 proxy.js 最后再启动 claude 就可以用了
