aws 视频上传s3

需要用的类

#import <AWSS3.h>

#import <AWSCore.h>

//1和2需要在aws控制台里面配置

1.权限配置：访问控制列表 必须公有

2.存储桶策略

需要在编辑器加以下代码

//"Resource": "arn:aws:s3:::@“存储桶的名称”/*"

//其他固定

{

    "Version": "2012-10-17",
    "Statement": [
        {
            "Sid": "AddPerm",
            "Effect": "Allow",
            "Principal": "*",
            "Action": "s3:GetObject",
            "Resource": "arn:aws:s3:::存储桶的名称/*"
        }
    ]

}

3. 在配置桶的时候 有一个js文件，需要倒入应用项目里面去，不然就闪退。

4.app里面的代码：

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {

 //aws-视频上传配置

//桶的id PoolId：存储桶的PoolId（比如：us-west-2:xxxx-xxxx-xxxxx-xxxx）

    AWSCognitoCredentialsProvider *credentialsProvider = [[AWSCognitoCredentialsProvider alloc] initWithRegionType:AWSRegionUSEast1 identityPoolId:@"存储桶的PoolId"];

    AWSServiceConfiguration *configuration = [[AWSServiceConfiguration alloc] initWithRegion:AWSRegionEUWest2 credentialsProvider:credentialsProvider];

    //   AWSServiceConfiguration *configuration = [[AWSServiceConfiguration alloc] initWithRegion:AWSRegionUSEast1 credentialsProvider:credentialsProvider];

    AWSServiceManager.defaultServiceManager.defaultServiceConfiguration = configuration;

}

//5需要在上传功能里面写的代码

-(void)goto_aws_vop:(NSString*)url_im{

    

    

    NSLog(@"开始");

    NSURL* url=[NSURL URLWithString:_load_vo_url];//视频的url

   

    AWSS3TransferUtilityUploadExpression* expression=[[AWSS3TransferUtilityUploadExpression alloc]init];

    expression.progressBlock = ^(AWSS3TransferUtilityTask * _Nonnull task, NSProgress * _Nonnull progress) {

        NSLog(@"expression==上传进度");

        NSLog(@"上传进度=%f",progress.fractionCompleted);

        

    };

   

    AWSS3TransferUtility* transferUtility=[AWSS3TransferUtility defaultS3TransferUtility];

    NSDateFormatter* formater = [[NSDateFormatter alloc] init];

    [formater setDateFormat:@"yyyyMMddHHmmss"];

    NSString* keyfileName = [NSString stringWithFormat:@"s3iosFolder/-%@.mp4",[formater stringFromDate:[NSDate date]]];

    //s3iosFolder/ 在桶里面创建文件夹的名称

    //text/plain  tet文件

    //video/mp4 视频

   //bucket js里面文件的值bucket（比如：ios项目名称-userfiles-mobilehub-xxxxxxx）

    [[transferUtility uploadFile:url bucket:@"js里面文件的值bucket" key:keyfileName contentType:@"video/mp4" expression:expression completionHandler:^(AWSS3TransferUtilityUploadTask * _Nonnull task, NSError * _Nullable error) {

        NSLog(@"uploadFile");

        NSLog(@"%@",error);

        NSLog(@"%@",task.request);

        if(error)

        {

        }else{

                //成功之后：视频的url地址 在aws控制台是固定的

            

    

           _aws_mp4_url=[NSString stringWithFormat:@"https://s3-us-west-2.amazonaws.com/bucket js里面文件的值bucket（比如：ios项目名称-userfiles-mobilehub-xxxxxxx）%@",keyfileName]; //上传成功的视频url

            

        }

        

    }]  continueWithBlock:^id _Nullable(AWSTask<AWSS3TransferUtilityUploadTask *> * _Nonnull t) {

        

        NSLog(@"%@",t.result);

        NSLog(@"回调");

        if (t.error) {

            NSLog(@"Error: %@", t.error);

        }

        

        return nil;

    }];
