GAS WEB 应用程序不返回对 POST 请求的响应

  • 772

从 Chrome 扩展，我转向 JS 到部署为 Web 应用程序的 GAS 脚本。JS请求脚本：

const fetchData = async (scriptURL, data) => {
        try {
            const response = await fetch(scriptURL, {
                mode: 'no-cors',
                method: 'POST',
                referrer: "",
                redirect: 'follow',
                body: JSON.stringify(data), // данные м
                headers: {
                    'Content-Type': 'application/json'
                }
                        
            });                             
            if (response != "") var json = await response.json();
            console.log('Успех:', JSON.stringify(json));
        } 
        catch (e){console.log('Ошибка:', e.message)}
            console.log('Tect:');
            
        return
    }

该请求通过 GAS 脚本，它正确处理它并返回 JSON，如下所示：

    function doPost(e){ 
          // обработка
    return ContentService.createTextOutput(JSON.stringify(response)).setMimeType(ContentService.MimeType.JSON);
}

但是，Chrome 扩展程序没有收到响应正文，在 DevTools=>Network=>Response 选项卡中给出错误“无法加载响应数据”。以下是初始请求和响应：

可能是什么问题呢？我已经打了2个星期，我在任何地方都找不到。似乎问题与 CORS 和 302 重定向有关（谷歌从不同的 url 发送响应）。提前致谢！

    一切都变得很困难：

    1. google web 应用程序不支持 OPTIONS 方法，因此它无法响应预检请求，该请求将带有 JSON 正文。厘米。
    2. 我不明白它是如何工作的，但它确实有效，我检查了。作者也无法解释。厘米。
