能否用官方客户端库创建Google Form？技术咨询及示例需求

为什么客户端库中找不到Forms API相关内容？ #

Google Forms API的客户端库确实存在，但并非所有通用客户端库文档都会直接高亮它。以Node.js的googleapis包为例，Forms API属于需要显式引用的服务，且必须先在Google Cloud控制台中启用Forms API服务，否则无法调用。官方文档的通用模板提示是有效的，并非不考虑可行性。

Node.js客户端库创建空白表单示例 #

步骤1：准备工作 #

1. 在Google Cloud控制台创建项目，启用Google Forms API
2. 创建服务账号密钥（JSON格式），下载后保存为service-account-key.json
3. 安装依赖：

npm install googleapis

步骤2：代码示例 #

const { google } = require('googleapis');
const fs = require('fs');

async function createBlankForm() {
  // 服务账号认证
  const auth = new google.auth.GoogleAuth({
    keyFile: 'service-account-key.json',
    scopes: ['https://www.googleapis.com/auth/forms.body'],
  });

  // 初始化Forms API客户端
  const forms = google.forms({ version: 'v1', auth });

  // 创建空白表单
  const response = await forms.forms.create({
    requestBody: {
      info: {
        title: 'Hello World 空白表单',
      },
    },
  });

  console.log('创建的表单ID:', response.data.formId);
  console.log('表单链接:', `https://docs.google.com/forms/d/${response.data.formId}/edit`);
}

createBlankForm().catch(console.error);

其他客户端库示例（Python） #

步骤1：安装依赖 #

pip install google-api-python-client google-auth-httplib2 google-auth-oauthlib

步骤2：代码示例 #

from googleapiclient.discovery import build
from google.oauth2.service_account import Credentials

SCOPES = ['https://www.googleapis.com/auth/forms.body']
KEY_FILE = 'service-account-key.json'

def create_blank_form():
    creds = Credentials.from_service_account_file(KEY_FILE, scopes=SCOPES)
    service = build('forms', 'v1', credentials=creds)

    # 创建表单请求
    form = {
        "info": {
            "title": "Hello World 空白表单"
        }
    }

    response = service.forms().create(body=form).execute()
    print(f"创建的表单ID: {response['formId']}")
    print(f"表单链接: https://docs.google.com/forms/d/{response['formId']}/edit")

if __name__ == '__main__':
    create_blank_form()

使用curl创建表单示例 #

步骤1：获取访问令牌 #

使用服务账号密钥获取Bearer令牌：

curl -s -X POST "https://oauth2.googleapis.com/token" \
  -H "Content-Type: application/x-www-form-urlencoded" \
  -d "grant_type=urn:ietf:params:oauth:grant-type:jwt-bearer&assertion=$(openssl dgst -sha256 -sign service-account-key.json <(echo -n '{"iss":"YOUR_SERVICE_ACCOUNT_EMAIL","scope":"https://www.googleapis.com/auth/forms.body","aud":"https://oauth2.googleapis.com/token","exp":'$(($(date +%s)+3600))',"iat":'$(date +%s)'}') | openssl base64 -A)"

替换YOUR_SERVICE_ACCOUNT_EMAIL为服务账号邮箱，执行后会返回包含access_token的JSON。

步骤2：创建表单 #

curl -X POST "https://forms.googleapis.com/v1/forms" \
  -H "Authorization: Bearer YOUR_ACCESS_TOKEN" \
  -H "Content-Type: application/json" \
  -d '{
    "info": {
      "title": "Hello World 空白表单"
    }
  }'

替换YOUR_ACCESS_TOKEN为上一步获取的令牌。

使用JavaScript fetch创建表单示例 #

// 建议在Node.js环境运行，浏览器环境使用服务账号密钥存在安全风险
const jwt = require('jsonwebtoken');
const fs = require('fs');

async function getAccessToken() {
  const serviceAccount = JSON.parse(fs.readFileSync('service-account-key.json', 'utf8'));
  
  const assertion = jwt.sign(
    {
      iss: serviceAccount.client_email,
      scope: 'https://www.googleapis.com/auth/forms.body',
      aud: 'https://oauth2.googleapis.com/token',
      exp: Math.floor(Date.now() / 1000) + 3600,
      iat: Math.floor(Date.now() / 1000)
    },
    serviceAccount.private_key,
    { algorithm: 'RS256' }
  );

  const response = await fetch('https://oauth2.googleapis.com/token', {
    method: 'POST',
    headers: { 'Content-Type': 'application/x-www-form-urlencoded' },
    body: `grant_type=urn:ietf:params:oauth:grant-type:jwt-bearer&assertion=${assertion}`
  });

  const data = await response.json();
  return data.access_token;
}

async function createFormWithFetch() {
  const token = await getAccessToken();
  const response = await fetch('https://forms.googleapis.com/v1/forms', {
    method: 'POST',
    headers: {
      'Authorization': `Bearer ${token}`,
      'Content-Type': 'application/json'
    },
    body: JSON.stringify({
      info: { title: 'Hello World 空白表单' }
    })
  });

  const formData = await response.json();
  console.log('表单ID:', formData.formId);
  console.log('表单链接:', `https://docs.google.com/forms/d/${formData.formId}/edit`);
}

createFormWithFetch().catch(console.error);
