使用Axios下载存在的Google Docs文件时返回404错误

我尝试通过Axios下载Google Docs中的文件，收到404错误。该文件确实存在且已设置共享，直接访问导出链接可正常触发下载，但使用Axios请求却失败。

我的Axios代码 #

const { data } = await axios({    
    method: 'get',    
    url,    
    responseType: 'arraybuffer'  
})

解决方案 #

1. 模拟浏览器请求头

Google Docs导出接口会验证请求的用户代理和接受头，Axios默认头可能不被识别，修改请求头如下：

const { data } = await axios({
    method: 'get',
    url,
    responseType: 'arraybuffer',
    headers: {
        'User-Agent': 'Mozilla/5.0 (Macintosh; Intel Mac OS X 10_15_7) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/114.0.0.0 Safari/537.36',
        'Accept': 'text/html,application/xhtml+xml,application/xml;q=0.9,image/avif,image/webp,*/*;q=0.8',
        'Referer': 'https://docs.google.com/'
    }
})

2. 确认共享权限

确保文件权限设置为「任何人有链接都可查看/下载」，如果是组织内部共享，Axios请求需携带身份验证信息（如Cookie或OAuth令牌）。

3. 启用重定向处理

Google Docs导出链接可能触发重定向，显式配置重定向参数：

const { data } = await axios({
    method: 'get',
    url,
    responseType: 'arraybuffer',
    maxRedirects: 5,
    followRedirects: true
})

4. 校验导出URL

确认URL中的文档ID和format参数（如docx、pdf）正确，直接复制浏览器中可正常下载的链接替换url变量。
