node.js - 在 lambda 函数中发送 JSON 响应时无服务器离线响应问题

Question

var result = [{
                count : 10,
                data : [{"id":11,"id":22}]
               }];
var response = {
                statusCode: 200,
                count: result.length,
                body: result
            };
            callback(null, response);

控制台错误

According to the API Gateway specs, the body content must be stringified. Check your Lambda response and make sure you are invoking JSON.stringify(YOUR_CONTENT) on your body object

这里的错误给了你解决方案。
API 网关的回调需要一个字符串而不是 javascript 对象。在将它传递给回调之前，您必须对其进行字符串化:

var result = [{
                count : 10,
                data : [{"id":11,"id":22}]
               }];
var response = {
                statusCode: 200,
                count: result.length,
                body: result
            };
            callback(null, JSON.stringify(response));

编辑:
然后在客户端解析 JSON 字符串以将其返回给一个对象(此示例假设您的客户端也是 Javascript):

var myObject = JSON.parse(responseBody);
