amazon-web-services - 告诉 Lambda@Edge 函数执行重定向的代码是什么？

Question

所以需要说明的是，我花了几个小时在谷歌上搜索，但没有任何效果。这不是一个“省力的帖子”。

这是我一直在尝试的代码示例。它不起作用。像这样 response.headers=[{Location:"foo"}] 或 response.headers=[{location:"foo"}] 或其他响应也不行我尝试过的八种方法。

exports.handler = (event, context, callback) => {
    if(request.uri === "/") {
    var response = {
        statusCode: 301,
        headers: {
            "location" : [{
                key: "Location",
                value: "foo"
            }]
        },
        body: null
    };
    callback(null, response);
}

您在问题中提到了指向此示例的链接；它应该与 Lambda 代理集成一起使用:

'use strict';

exports.handler = function(event, context, callback) {
var response = {
    statusCode: 301,
    headers: {
        "Location" : "http://example.com"
    },
    body: null
};
callback(null, response);
};

更新:

否则，请尝试使用 this page of example functions 中的示例:

'use strict';

exports.handler = (event, context, callback) => {
/*
 * Generate HTTP redirect response with 302 status code and Location header.
 */
const response = {
    status: '302',
    statusDescription: 'Found',
    headers: {
        location: [{
            key: 'Location',
            value: 'http://docs.aws.amazon.com/lambda/latest/dg/lambda-edge.html',
        }],
    },
};
callback(null, response);
};
