我试图使用AmzaonWebService Api Gateway SDK for Javascript但没有成功。
我一直都是控制台错误消息：＆＃34;访问控制允许原点丢失＆＃34;
我就是这样做的：
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);
})
};
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;
}
有人知道我做错了吗？
答案 0 :(得分：0)
您需要在API Gateway的响应上设置CORS标头，并将OPTION方法设置为飞行前方法。我有一个示例swagger文件，其中有CORS设置。你可能想看看。
