我正在尝试在 Angular 2 中为 AWS Cognito 使用 listUsers 函数。每次调用该函数时,我都会收到错误消息,指出 listUsers 不是函数。
我正在使用适用于 Angular 2 ( https://github.com/awslabs/aws-cognito-angular2-quickstart ) 的 AWS Cognito 快速入门示例,我正在添加到 cognito.service.ts 文件以尝试合并 listUsers 功能。
Cognito ( http://docs.aws.amazon.com/AWSJavaScriptSDK/latest/AWS/CognitoIdentityServiceProvider.html#listUsers-property ) 的 Javascript SDK 的文档说调用函数如下:
var params = {
UserPoolId: 'STRING_VALUE', /* required */
AttributesToGet: [
'STRING_VALUE',
/* more items */
],
Filter: 'STRING_VALUE',
Limit: 0,
PaginationToken: 'STRING_VALUE'
};
cognitoidentityserviceprovider.listUsers(params, function(err, data) {
if (err) console.log(err, err.stack); // an error occurred
else console.log(data); // successful response
});
我尝试在 cognito.service.ts 中使用 listUsers 函数,如下所示:
@Injectable()
export class CognitoUtil {
public static _REGION = environment.region;
public static _IDENTITY_POOL_ID = environment.identityPoolId;
public static _USER_POOL_ID = environment.userPoolId;
public static _CLIENT_ID = environment.clientId;
public static _POOL_DATA = {
UserPoolId: CognitoUtil._USER_POOL_ID,
ClientId: CognitoUtil._CLIENT_ID
};
public static getAwsCognito(): any {
return AWSCognito;
}
getUserPool() {
return new AWSCognito.CognitoIdentityServiceProvider.CognitoUserPool(CognitoUtil._POOL_DATA);
}
getCurrentUser() {
return this.getUserPool().getCurrentUser();
}
getList(myparams){
var params = {
UserPoolId: environment.userPoolId, /* required */
AttributesToGet: [],
Filter: "",
Limit: 10
};
var cognito = new AWSCognito.CognitoIdentityServiceProvider.CognitoUserPool(CognitoUtil._POOL_DATA);
cognito.listUsers(params, function(err, data) {
if (err) console.log(err, err.stack);// an error occurred
else return data;// successful response
});
}
getCognitoIdentity(): string {
return AWS.config.credentials.identityId;
}
getAccessToken(callback: Callback): void {
if (callback == null) {
throw("CognitoUtil: callback in getAccessToken is null...returning");
}
if (this.getCurrentUser() != null)
this.getCurrentUser().getSession(function (err, session) {
if (err) {
console.log("CognitoUtil: Can't set the credentials:" + err);
callback.callbackWithParam(null);
}
else {
if (session.isValid()) {
callback.callbackWithParam(session.getAccessToken().getJwtToken());
}
}
});
else
callback.callbackWithParam(null);
}
getIdToken(callback: Callback): void {
if (callback == null) {
throw("CognitoUtil: callback in getIdToken is null...returning");
}
if (this.getCurrentUser() != null)
this.getCurrentUser().getSession(function (err, session) {
if (err) {
console.log("CognitoUtil: Can't set the credentials:" + err);
callback.callbackWithParam(null);
}
else {
if (session.isValid()) {
callback.callbackWithParam(session.getIdToken().getJwtToken());
} else {
console.log("CognitoUtil: Got the id token, but the session isn't valid");
}
}
});
else
callback.callbackWithParam(null);
}
getRefreshToken(callback: Callback): void {
if (callback == null) {
throw("CognitoUtil: callback in getRefreshToken is null...returning");
}
if (this.getCurrentUser() != null)
this.getCurrentUser().getSession(function (err, session) {
if (err) {
console.log("CognitoUtil: Can't set the credentials:" + err);
callback.callbackWithParam(null);
}
else {
if (session.isValid()) {
callback.callbackWithParam(session.getRefreshToken());
}
}
});
else
callback.callbackWithParam(null);
}
refresh(): void {
this.getCurrentUser().getSession(function (err, session) {
if (err) {
console.log("CognitoUtil: Can't set the credentials:" + err);
}
else {
if (session.isValid()) {
console.log("CognitoUtil: refreshed successfully");
} else {
console.log("CognitoUtil: refreshed but session is still not valid");
}
}
});
}
}
这就是我在组件中调用 getList(params) 的方式:
constructor(public cognitoUtil: CognitoUtil){}
viewUsers(){
console.log(this.cognitoUtil.getList(this.param));
}
我已经尝试了多次不同的方法来让它工作,但我似乎无法让它工作。我尝试使用 ListUsers 而不是 listUsers,并且尝试调用 getUserPool() 而不是使用 AWSCognito.CognitoIdentityServiceProvider.CognitoUserPool(CognitoUtil._POOL_DATA)。
更新
我已更改AWSCognito.CognitoIdentityServiceProvider.CognitoUserPool
为AWS.CognitoIdentityServiceProvider
喜欢建议。我现在收到错误:
ConfigError: Missing region in config
