我目前无法授权使用 Facebook 和 Google+ 作为提供者的 AWS iOS SDK V2 的用户。
我不确定它是我在 AWS 开发人员控制台上的设置，还是它的代码。
这是身份池的角色策略：
{
"Version": "2012-10-17",
"Statement": [{
"Action": [
"mobileanalytics:PutEvents",
"cognito-sync:*"
],
"Effect": "Allow",
"Resource": ["*"]
}]
我确实收到了未经授权的 Cognito ID，但是当我尝试使用 Facebook 或 Google+ 提供商身份验证时，它不起作用。
一旦 Facebook 登录返回，我就可以成功地使用用户属性来提取个人资料图片、姓名和电子邮件地址。然后我从 Facebook 会话中获取令牌（是的，它是一个很长的字符串）并在 deviceID 类中使用它：
- (void)loginViewFetchedUserInfo:(FBLoginView *)loginView
user:(id<FBGraphUser>)user {
//Populate viewcontoller with Facebook data
self.profilePictureView.profileID = user.id;
NSRange range = [user.name rangeOfString:@" "];
self.firstName.text = [user.name substringToIndex:range.location];
self.lastName.text = [user.name substringFromIndex:range.location+1];
self.emailAddress.text = [user objectForKey:@"email"];
//Get Facebook token, set then get Cognito device ID - in DeviceId class
NSString *token = FBSession.activeSession.accessTokenData.accessToken;
DeviceId *myDeviceId = [DeviceId sharedInstance];
cognitoDeviceId = [myDeviceId setFacebookToken:token];
}
DeviceID 类实现如下所示：
#import "DeviceId.h"
#import <AWSiOSSDKv2/AWSCore.h>
#import <AWSCognitoSync/Cognito.h>
@implementation DeviceId
static NSString *cognitoId;
static DeviceId *_sharedInstance;
static AWSCognitoCredentialsProvider *credentialsProvider;
static AWSServiceConfiguration *configuration;
+ (DeviceId *) sharedInstance
{
if (!_sharedInstance)
{
_sharedInstance = [[DeviceId alloc] init];
}
return _sharedInstance;
}
- (NSString *) getDeviceId
{
return cognitoId;
}
- (void) setDeviceId
{
/*
* AWS Cognito
*/
credentialsProvider = [AWSCognitoCredentialsProvider
credentialsWithRegionType:AWSRegionUSEast1
accountId:@"(accountID"
identityPoolId:@"(identityPool)"
unauthRoleArn:@"arn:aws:iam::(accountID):role/Cognito_(app)UsersUnauth_DefaultRole"
authRoleArn:@"arn:aws:iam::(accountID):role/Cognito_(app)UsersAuth_DefaultRole"];
configuration = [AWSServiceConfiguration configurationWithRegion:AWSRegionUSEast1
credentialsProvider:credentialsProvider];
[AWSServiceManager defaultServiceManager].defaultServiceConfiguration = configuration;
// Retrieve the cognito ID.
cognitoId = credentialsProvider.identityId;
if (!cognitoId) {
UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"Identification Error"
message:@"Error on User Account."
delegate:nil
cancelButtonTitle:@"OK"
otherButtonTitles:nil];
[alert show];
}
}
-(NSString *)setFacebookToken:(NSString*)token {
credentialsProvider.logins = @{ @(AWSCognitoLoginProviderKeyFacebook): token };
[self setDeviceId];
return cognitoId;
}
-(NSString *)setGooglePlusToken:(NSString*)token {
credentialsProvider.logins = @{ @(AWSCognitoLoginProviderKeyGoogle): token };
[self setDeviceId];
return cognitoId;
}
@end
我没有收到任何错误消息，并且上面的仪表板从不显示经过身份验证的用户。CognitoID 永远不会改变它的值。有人可以告诉我问题出在哪里吗？
编辑：基于评论更新的 DeviceId.m 仍然为 cognitoId 返回 nil
编辑 2：更新 DeviceId.m 以替换 while 循环检查 BFTask 是否已完成到 Bolts 方法 waitUntilFinished。
#import "DeviceId.h"
#import <AWSiOSSDKv2/AWSCore.h>
#import <AWSCognitoSync/Cognito.h>
@implementation DeviceId
{
__block NSString *tempCognitoId;
}
static NSString *cognitoId;
static DeviceId *_sharedInstance;
static AWSCognitoCredentialsProvider *credentialsProvider;
static AWSServiceConfiguration *configuration;
+ (DeviceId *) sharedInstance
{
if (!_sharedInstance)
{
_sharedInstance = [[DeviceId alloc] init];
}
return _sharedInstance;
}
- (NSString *) getDeviceId
{
return cognitoId;
}
- (void) setDeviceId
{
/*
* AWS Cognito
*/
credentialsProvider = [AWSCognitoCredentialsProvider
credentialsWithRegionType:AWSRegionUSEast1
identityPoolId:@"Identity Pool ID"];
configuration = [AWSServiceConfiguration
configurationWithRegion:AWSRegionUSEast1
credentialsProvider:credentialsProvider];
[AWSServiceManager defaultServiceManager].defaultServiceConfiguration = configuration;
BFTask *taskIdentity = [[credentialsProvider refresh] continueWithBlock:^id(BFTask *task){
if (task.error == nil)
{
tempCognitoId = credentialsProvider.identityId;
NSLog(@"cognitoId: %@", cognitoId);
}
else
{
NSLog(@"Error : %@", task.error);
}
return nil;
}];
[taskIdentity waitUntilFinished];
cognitoId = tempCognitoId;
}
-(NSString *)setFacebookToken:(NSString*)token {
credentialsProvider.logins = @{ @(AWSCognitoLoginProviderKeyFacebook): token };
BFTask *taskIdentity = [[credentialsProvider refresh] continueWithBlock:^id(BFTask *task){
if (task.error == nil)
{
tempCognitoId = credentialsProvider.identityId;
NSLog(@"cognitoId: %@", tempCognitoId);
}
else
{
NSLog(@"Error : %@", task.error);
}
return nil;
}];
[taskIdentity waitUntilFinished];
cognitoId = tempCognitoId;
return cognitoId;
}
-(NSString *)setGooglePlusToken:(NSString*)token {
credentialsProvider.logins = @{ @(AWSCognitoLoginProviderKeyGoogle): token };
BFTask *taskIdentity = [[credentialsProvider getIdentityId] continueWithBlock:^id(BFTask *task){
if (task.error == nil)
{
tempCognitoId = credentialsProvider.identityId;
NSLog(@"cognitoId: %@", tempCognitoId);
}
else
{
NSLog(@"Error : %@", task.error);
}
return nil;
}];
[taskIdentity waitUntilFinished];
cognitoId = tempCognitoId;
return cognitoId;
}
@end
我确实意识到有些人可能认为等待完成是不好的做法，但为了测试目的，我需要确保 cognitoId 是“同步”返回的。修改 Facebook App ID 后，使用此方法返回 cognitoID。
编辑 3：但是，Google+ 在到达 deviceId 之前失败。
- (void)finishedWithAuth:(GTMOAuth2Authentication *)auth
error:(NSError *)error {
if (error) {
_signInAuthStatus.text =
[NSString stringWithFormat:@"Status: Authentication error: %@", error];
NSLog(@"%@", error);
return;
}
NSString *idToken = [auth.parameters objectForKey:@"id_token"];
DeviceId *myDeviceId = [DeviceId sharedInstance];
[myDeviceId setGooglePlusToken:idToken];
}
NSLog 错误打印：Error Domain=com.google.GooglePlusPlatform Code=-1 "The operation could not be completed. (com.google.HTTPStatus error 400.)" API & Auth Product Name 和 Current Email Address 似乎是在控制台上正确。
编辑 4：代码的另一部分中的 Cognito Synch 现在已停止在以前工作的地方工作：
AWSCognito *syncClient = [AWSCognito defaultCognito];
AWSCognitoDataset *dataset = [syncClient openOrCreateDataset:@"myDataSet"];
NSString *fullName = [dataset stringForKey:@"name"];
在第一行失败并出现错误：
*** 由于未捕获的异常“NSInvalidArgumentException”而终止应用程序，原因：“+[AWSEndpoint endpointWithRegion:service:]: unrecognized selector sent to class
感谢您对这些额外错误的任何帮助。
