Amazon web services API创新不会触发AWS API网关基于自定义请求的lambda授权程序

已经为我的AWS API网关创建了一个简单的基于请求的基本授权程序，如下文档（）

在测试授权者时（使用虚拟设置验证授权头中是否有键“test”），授权者工作正常，但在直接从端点调用API时，根本不调用授权者，我得到API响应（由于没有传递头，应该阻止该响应）

具有无效密钥的授权人测试：正在获取预期值

具有有效密钥的授权人测试：预期达到200

从web直接调用API端点成功：

API网关的我的资源策略仅限于特定IP范围：

{
    "Version": "2012-10-17",
    "Statement": [
        {
            "Effect": "Allow",
            "Principal": "*",
            "Action": "execute-api:Invoke",
            "Resource": "arn:aws:execute-api:us-east-1:111111111111:6mm9kw17uf/*/*/*"
        },
        {
            "Effect": "Deny",
            "Principal": "*",
            "Action": "execute-api:Invoke",
            "Resource": "arn:aws:execute-api:us-east-1:111111111111:6mm9kw17uf/*/*/*",
            "Condition": {
                "NotIpAddress": {
                    "aws:SourceIp": "XXXXXXX"
                }
            }
        }
    ]
}

授权人Lambda代码：

exports.handler = function(event, context, callback) {        
    console.log('Received event:', JSON.stringify(event, null, 2));

    // Retrieve request parameters from the Lambda function input:
    var headers = event.headers;
        
    // Parse the input for the parameter values
    var tmp = event.methodArn.split(':');
    var apiGatewayArnTmp = tmp[5].split('/');
    var awsAccountId = tmp[4];
    var region = tmp[3];
    var restApiId = apiGatewayArnTmp[0];
    var stage = apiGatewayArnTmp[1];
    var method = apiGatewayArnTmp[2];
    var resource = '/'; // root resource
    if (apiGatewayArnTmp[3]) {
        resource += apiGatewayArnTmp[3];
    }
        
    // Perform authorization to return the Allow policy for correct parameters and 
    // the 'Unauthorized' error, otherwise.
    var authResponse = {};
    var condition = {};
    condition.IpAddress = {};
     
    if (headers.Authorization === "test") {
        callback(null, generateAllow('me', event.methodArn));
    }  else {
        callback("Unauthorized");
    }
}
     
// Help function to generate an IAM policy
var generatePolicy = function(principalId, effect, resource) {
    // Required output:
    var authResponse = {};
    authResponse.principalId = principalId;
    if (effect && resource) {
        var policyDocument = {};
        policyDocument.Version = '2012-10-17';
        policyDocument.Statement = [];
        var statementOne = {};
        statementOne.Action = 'execute-api:Invoke';
        statementOne.Effect = effect;
        statementOne.Resource = resource;
        policyDocument.Statement[0] = statementOne;
        authResponse.policyDocument = policyDocument;
    }
    return authResponse;
}
     
var generateAllow = function(principalId, resource) {
    return generatePolicy(principalId, 'Allow', resource);
}
     
var generateDeny = function(principalId, resource) {
    return generatePolicy(principalId, 'Deny', resource);
}

我已经尝试过的：

在添加了授权者之后，我已经重新部署了API

我是从邮递员和网络浏览器测试这一点，而不是网关测试，因为它将绕过授权

---

我尝试使用自己的API网关复制该问题，但我还没有发现lambda函数存在任何问题。它按预期工作

授权呼叫的示例：

要考虑的事情：

将授权人添加到api方法时，必须再次部署阶段

在新授权人开始工作之前，需要时间。因此，在启用它并创建新阶段后，必须等待几分钟，直到它开始工作

嗨，Marcin很奇怪，因为我再次部署了舞台，等了很长时间，但它仍然不起作用。是否需要从API网关添加其他内容？因为出于某种原因，它没有被触发。我需要更新资源策略吗？@KumarVivek是否已将lambda函数指定为

helloworld

资源的GET方法的授权？仅仅创建授权人是不够的。您必须将其附加到您希望使用的每个方法和资源。@KumarVivek另外，在每次更改API后，不要忘记重新部署阶段。我想我忘了，让我试试。
