使用适用于Java的AWS API Gateway SDK
[英]Using the AWS API Gateway SDK for Javascript
问题描述
I'm trying to use the AmzaonWebService Api Gateway SDK for Javascript without success. 
我试图将AmzaonWebService Api Gateway SDK用于Javascript，但未成功。
I've all the time the console error message : "Access Control Allow origin missing" 我一直在出现控制台错误消息：“访问控制允许缺少来源”
This is how I do: 这是我的方法：
dataFactory.setConfig = function() {
var config = {
accessKey: 'xxxxxxxxxxxxxx', // AWS Access KEY ID
secretKey: 'xxxxxxxxxx/xxxxxxxxxx/xxxxxxxx', // AWS Secret Key ID
sessionToken: dataFactory.getCognitoCredentials().idToken.jwtToken,
region: 'eu-west-1',
apiKey: undefined,
defaultContentType: 'application/json',
defaultAcceptType: 'application/json'
};
return config
}
var apigClient = apigClientFactory.newClient(dataFactory.setConfig());
dataFactory.getAll = function() {
var params = {
headers: {
"Access-Control-Allow-Origin": "*"
}
}
apigClient.allGet(params).then(function(res) {
console.log(res);
return res
}).catch(function(res) {
console.log(res);
})
};
This is how I'm getting the credentials: 这就是我获取凭据的方式：
dataFactory.getCognitoCredentials = function() {
var res;
var poolData = {
UserPoolId: 'eu-west-1_xxxxxxxx',
ClientId: 'xxxxxxxxxxxxxxx'
};
var userPool = new AWSCognito.CognitoIdentityServiceProvider.CognitoUserPool(poolData);
var cognitoUser = userPool.getCurrentUser();
if (cognitoUser != null) {
cognitoUser.getSession(function(err, session) {
if (err) {
alert(err);
return;
}
res = session
});
}
return res;
}
Does someone know what I'm doing wrong ? 有人知道我在做什么错吗？

You need to setup the CORS headers on API Gateway's response and an OPTION method as a pre-flight method. 您需要在API网关的响应上设置CORS标头，并将OPTION方法设置为飞行前方法。 I have an example swagger file which has CORS setup. 我有一个示例示例文件，其中包含CORS设置。 You might want to take a look. 您可能想看看。
