调用Patreon API时出现401 Unauthorized错误，寻求解决方案

我已经查阅资料、浏览官方文档并咨询ChatGPT，但仍未找到修复401错误的方法。以下是我的代码实现：

import express from 'express';
import fetch from 'node-fetch';

const app = express();

const creatorId = 'creator-ID';
const accessToken = 'access-Token';

app.get('/creator', async (req, res) => {
    try {
        const response = await fetch(`https://www.patreon.com/api/oauth2/v2/campaigns/${creatorId}`, {
            headers: {
                'Authorization': `Bearer ${accessToken}`
            }
        });
        const json = await response.json();
        res.json(json);
    } catch (err) {
        res.status(500).json({ error: err.message });
    }
});

app.listen(3000, () => {
    console.log('Server listening on port 3000');
});

错误信息如下：

{"errors":[{"code":1,"code_name":"Unauthorized","detail":"The server could not verify that you are authorized to access the URL requested. You either supplied the wrong credentials (e.g. a bad password), or your browser doesn't understand how to supply the credentials required.","id":"d2b03413-652e-5a35-a0ea-efe87bbd5995","status":"401","title":"Unauthorized"}]}

排查要点 #

• 检查AccessToken有效性：确认access-Token是通过正确OAuth2流程获取，未过期且具备访问创作者campaign的权限。Patreon的AccessToken会过期，需及时刷新。
• 验证CreatorID正确性：确保creator-ID是当前AccessToken对应创作者的正确ID，格式无错误（比如是否为指定的字符串或数字格式）。
• 请求头格式校验：确认Authorization头格式完全正确，严格遵循Bearer + 空格 + AccessToken的结构，无多余空格或拼写错误。
• 权限范围确认：获取AccessToken时，是否申请了campaigns相关的权限范围，权限不足会直接返回401。
• API端点检查：确认请求URL是Patreon API v2的正确端点，无拼写错误。
