Question

我正面临着AWSS3的一个奇怪问题。

设定：

AWS Mobile HUB
Cognito
DynamoDB
S3

- ＆GT; Cognito，Dynamo＆amp;甚至S3（通过认知用户数据）工作。

但是我现在尝试使用以下代码直接连接到AWS3：＆＃34;

let transferManager = AWSS3TransferManager.default()
                            let uploadRequest = AWSS3TransferManagerUploadRequest()
                            uploadRequest?.bucket = "XXXXXXXXXXXX"
                            uploadRequest?.key = "user-data/" + awsId! + "/primary_profile_picture.png"
                            uploadRequest?.body = imgUrl as URL

                            transferManager.upload(uploadRequest!).continueWith(executor: AWSExecutor.mainThread(), block: { (task:AWSTask<AnyObject>) -> Any? in

                                if let error = task.error as? NSError {
                                    if error.domain == AWSS3TransferManagerErrorDomain, let code = AWSS3TransferManagerErrorType(rawValue: error.code) {
                                        switch code {
                                        case .cancelled, .paused:
                                            break
                                        default:
                                            print("Error uploading: \(uploadRequest?.key) Error: \(error)")
                                        }
                                    } else {
                                        print("Error uploading: \(uploadRequest?.key) Error: \(error)")
                                    }
                                    return nil
                                }

                                let uploadOutput = task.result
                                print("Upload complete for: \(uploadRequest?.key)")
                                return nil
                            })

我收到了错误：

AWSiOSSDK v2.5.1 [Debug] AWSInfo.m line:122 | -[AWSServiceInfo initWithInfoDictionary:checkRegion:] | Couldn't read the region configuration from Info.plist for the client. Please check your `Info.plist` if you are providing the SDK configuration values through `Info.plist`.
2017-02-20 19:29:21.748997 [2210:1152801] *** Terminating app due to uncaught exception 'NSInternalInconsistencyException', reason: 'The service configuration is `nil`. You need to configure `Info.plist` or set `defaultServiceConfiguration` before using this method.'

我正在使用从AWS Mobiel HUB下载的plist配置，因此它有点惊讶它不起作用（正如所有其他组件那样）。

任何想法可能是什么问题？ plist实际上包含桶ID和amp;区域。

Answer 1

对我来说，在上传之前，我必须使用以下代码配置凭据：

let credentialsProvider = AWSCognitoCredentialsProvider(regionType:.USEast1,identityPoolId:PoolID)
let configuration = AWSServiceConfiguration(region:.USEast1, credentialsProvider:credentialsProvider)

AWSServiceManager.default().defaultServiceConfiguration = configuration

其中PoolID是我的Cognito身份。我希望这有助于其他人。

Answer 2

您的info.plist需要包含S3TransferManager。

所以，-- User defined table-valued function Create Function dbo.udf_GetSalesByCompany (@companyName varchar(25) ) RETURNS TABLE AS RETURN Select * from sales where Company_Name = @company1; --Usage SELECT * FROM dbo.udf_GetSalesByCompany('AA'); SELECT * FROM dbo.udf_GetSalesByCompany('BB'); -- Usage with params DECLARE @company1 varchar(25) set @company1 = 'AA'; SELECT * FROM dbo.udf_GetSalesByCompany(@company1); set @company1 = 'BB'; SELECT * FROM dbo.udf_GetSalesByCompany(@company1);

您可以找到一个here

的示例

Answer 3

我有同样的问题而不是S3TransferManager你应该放置DynamoDBObjectMapper

e.g ..

<key>DynamoDBObjectMapper</key>
    <dict>
        <key>Default</key>
        <dict>
            <key>Region</key>
            <string>us-east-1</string>
        </dict>
    </dict>

Answer 4

Swift 3 - Xcode 8.3.3

对于仍然遇到这个问题的人，我只花了3个小时来对付这个烦人的设置问题。

我在Info.plist中添加了这些块（在第二个块中替换** **之间的变量），现在它再次工作。

我认为亚马逊的文档没有正确更新。我希望这可以节省一些人的时间。

<key>NSAppTransportSecurity</key>
    <dict>
        <key>NSAllowsArbitraryLoads</key>
        <true/>
        <key>NSExceptionDomains</key>
        <dict>
            <key>amazonaws.com</key>
            <dict>
                <key>NSThirdPartyExceptionMinimumTLSVersion</key>
                <string>TLSv1.0</string>
                <key>NSThirdPartyExceptionRequiresForwardSecrecy</key>
                <false/>
                <key>NSIncludesSubdomains</key>
                <true/>
            </dict>
            <key>amazonaws.com.cn</key>
            <dict>
                <key>NSThirdPartyExceptionMinimumTLSVersion</key>
                <string>TLSv1.0</string>
                <key>NSThirdPartyExceptionRequiresForwardSecrecy</key>
                <false/>
                <key>NSIncludesSubdomains</key>
                <true/>
            </dict>
        </dict>
    </dict>

和：

<key>AWS</key>
    <dict>
        <key>CredentialsProvider</key>
        <dict>
            <key>CognitoIdentity</key>
            <dict>
                <key>Default</key>
                <dict>
                    <key>PoolId</key>
                    <string>**YourCognitoIdentityPoolId**</string>
                    <key>Region</key>
                    <string>**AWSRegionUnknown**</string>
                </dict>
            </dict>
        </dict>
        <key>S3TransferManager</key>
        <dict>
            <key>Default</key>
            <dict>
                <key>Region</key>
                <string>**AWSRegionUnknown**</string>
            </dict>
        </dict>
    </dict>

Answer 5

问题是，地区应该是：

us-east-1

而不是; US_EAST_1

Answer 6

使用数据添加服务配置文件

如果上面标记的解决方案在某些情况下不起作用。尝试以下解决方案。

正如错误所说，服务配置文件为零。因此，我们需要添加具有以下数据的 awsconfiguration.json 文件。

{
  "Version": "1.0",
  "IdentityManager": {
    "Default": {}
  },
"CredentialsProvider": {
  "CognitoIdentity": {
    "Default": {
      "PoolId": "REPLACE_ME",
      "Region": "REPLACE_ME"
    }
  }
},
  "S3TransferUtility": {
    "Default": {
      "Bucket": "REPLACE_ME",
      "Region": "REPLACE_ME"
    }
  }
}

替换项目的bucket、region、poolId。
