KS3 SDK for iOS使用指南

SDK下载地址

目录


开发前准备

SDK使用准备

  • 申请AccessKey、SecretKey

SDK配置

SDK以动态库的形式呈现。请将KS3iOSSDK.framework添加到项目工程中。如果开发工具是Xcode6,请在project->target->General中的‘Embedded Binaries‘中添加KS3iOSSDK.framework

运行环境

支持iOS6及以上版本

安全性

使用场景

由于在App端明文存储AccessKey、SecretKey是极不安全的,因此推荐的使用场景如下图所示:

KS3Client初始化

  • 利用AccessKey、SecretKey初始化

对应的初始化代码如下:

[[KS3Client initialize] connectWithAccessKey:strAccessKey withSecretKey:strSecretKey];

常见术语介绍

Object(对象,文件)

在KS3中,用户操作的基本数据单元是Object。单个Object允许存储0~48.8TB的数据。 Object 包含key和data。其中,key是Object的名字;data是Object 的数据。key为UTF-8编码,且编码后的长度不得超过1024个字符。

Key(文件名)

即Object的名字,key为UTF-8编码,且编码后的长度不得超过1024个字符。Key中可以带有斜杠,当Key中带有斜杠的时候,将会自动在控制台里组织成目录结构。

其他术语请参考概念与术语

SDK介绍及使用

核心类介绍

  • KS3Client 封装接入Web Service的一系列操作,提供更加便利的接口以及回调。

为方便开发者使用,SDK在REST API接口返回值基础上进行了封装,具体更多封装类详情请见
SDK-REST API

[[KS3Client initialize] putObject:putObjRequest];

2.有些情况下,如果希望KS3上传文件完成后通知服务端,需要注册回调参数。使用方法:

/* 一定要实现委托方法 (这种情况如果实现委托,返回的reponse一般返回为nil,具体获取返回对象需要到委托方法里面获取,如果不实现委托,reponse不会为nil*/
KS3PutObjectRequest *putObjRequest = [[KS3PutObjectRequest alloc] initWithName:@"testcreatebucket-wf111" withAcl:nil grantAcl:nil];
//设置object权限为公开读
KS3AccessControlList *acl = [[KS3AccessControlList alloc] init];
[acl setContronAccess:KingSoftYun_Permission_Public_Read];
[putObjRequest setAcl:acl];
putObjRequest.delegate = self;
NSString *fileName = [[NSBundle mainBundle] pathForResource:@"test" ofType:@"jpg"];
putObjRequest.data = [NSData dataWithContentsOfFile:fileName options:NSDataReadingMappedIfSafe error:nil];
putObjRequest.filename = [fileName lastPathComponent];
//设置回调函数
putObjRequest.callbackUrl = @"http://123.59.36.81/index.php/api/photos/callback";
//设置回调参数,回调参数支持自定义参数、常量和魔法变量。如下所示:kss-location和kss-name为自定义参数,key和etag为魔法变量。
//支持的魔法变量详见上传回调处理说明文档([https://docs.ksyun.com/documents/956](https://docs.ksyun.com/documents/956))
putObjRequest.callbackBody = @"location=${kss-location}&name=${kss-name}&uid=8888&objectKey=${key}&etag=${etag}";
//设置自定义参数,必须以"kss-"开始
putObjRequest.callbackParams = @{@"kss-location": @"china_location", @"kss-name": @"lulu_name"};

[[KS3Client initialize] putObject:putObjRequest];

Initiate Multipart Upload

调用这个接口会初始化一个分块上传,KS3 Server会返回一个upload id, upload id 用来标识属于当前object的具体的块,并且用来标识完成分块上传或者取消分块上传

方法名:

- (KS3MultipartUpload *)initiateMultipartUploadWithKey:(NSString *)theKey withBucket:(NSString *)theBucket

参数说明:

  • theKey:指定的Object名称
  • theBucket:指定的Bucket名称

返回结果:

代码示例:

KS3InitiateMultipartUploadRequest *request = [[KS3InitiateMultipartUploadRequest alloc] initWithKey:strObjectName inBucket:strBucketName acl:nil grantAcl:nil];
KS3MultipartUpload *upload = [[KS3Client initialize] initiateMultipartUploadWithRequest:request];

Upload Part

初始化分块上传后,上传分块接口。Part number 是标识每个分块的数字,介于0-10000之间。除了最后一块,每个块必须大于等于5MB,最后一块没有这个限制。

方法名:

- (KS3UploadPartResponse *)uploadPart:(KS3UploadPartRequest *)uploadPartRequest;

参数说明:

  • uploadPartRequest:上传块的KS3UploadPartRequest对象,它需要指定上传的Object名称,指定的Bucket的名称,分块的块号,此块的数据

返回结果:

代码示例:

KS3UploadPartRequest *req = [[KS3UploadPartRequest alloc] initWithMultipartUpload:upload partNumber:partNumber data:data generateMD5:NO];
req.delegate = self;
KS3UploadPartResponse *response = [[KS3Client initialize] uploadPart:req];

List Parts

罗列出已经上传的块

方法名:

参数说明:

  • listPartsRequest:罗列已经上传的块的KS3ListPartsRequest对象,它包含指定的Object的名称,此次上传的Upload ID,maxParts,它表示块大小限制,类型:字符串,默认值:None,partNumberMarker,它表示块号标记,将返回大于此块号的分块,类型:字符串,默认值:None

返回结果:

  • 罗列已经上传的块的HTTP请求响应,它包含了类型为KS3ListPartsResult的请求的结果,它包含指定的Bucket名称,指定的Object名称,此次上传的Upload ID,partNumberMarker,它表示块号标记,将返回大于此块号的分块,maxParts,它表示块大小限制,isTruncated,它表示是否取完分块,Owner它表示创建分块上传的用户

代码示例:

KS3ListPartsRequest *req2 = [[KS3ListPartsRequest alloc] initWithMultipartUpload:_muilt];
KS3ListPartsResponse *response2 = [[KS3Client initialize] listParts:req2];

Abort Multipart Upload

取消分块上传。

方法名:

- (KS3AbortMultipartUploadResponse *)abortMultipartUpload:(KS3AbortMultipartUploadRequest *)abortMultipartRequest

参数说明:

返回结果:

  • 取消上传的HTTP请求响应

代码示例:

KS3AbortMultipartUploadRequest * request = [[KS3AbortMultipartUploadRequest alloc] initWithMultipartUpload: _muilt];
KS3AbortMultipartUploadResponse * response = [[KS3Client initialize] abortMultipartUpload: request];
if (response.httpStatusCode == 204) {
    NSLog(@"Abort multipart upload success!");
} 
else {
    NSLog(@"error: %@", response.error.description);
}

Complete Multipart Upload

组装之前上传的块,然后完成分块上传。通过你提供的xml文件,进行分块组装。在xml文件中,块号必须使用升序排列。必须提供每个块的ETag值。

方法名:

- (KS3CompleteMultipartUploadResponse *)completeMultipartUpload:(KS3CompleteMultipartUploadRequest *)completeMultipartUploadRequest;

参数说明:

  • completeMultipartUploadRequest:组装上传所有块的KS3CompleteMultipartUploadRequest对象,它包含指定的Bucket名称,Object名称,此次上传的Upload ID,需要组装的所有块的信息数据

返回结果:

  • 组装所有块的HTTP请求响应

代码示例:

KS3ListPartsResponse * response2 = [[KS3Client initialize] listParts: req2];
KS3CompleteMultipartUploadRequest * req = [[KS3CompleteMultipartUploadRequest alloc] initWithMultipartUpload: _muilt];
for (KS3Part * part in response2.listResult.parts) { 
    [req addPartWithPartNumber: part.partNumber withETag: part.etag];
} 
[[KS3Client initialize] completeMultipartUpload: req];

Multipart Upload Example Code

分块上传代码示例

NSFileHandle * fileHandle = [NSFileHandle fileHandleForReadingAtPath: [[NSBundle mainBundle] pathForResource: @"bugDownload"ofType: @"txt"]];
long long fileLength = [[fileHandle availableData] length];
long long partLength = 5 * 1024.0 * 1024.0;
_partInter = (ceilf((float) fileLength / (float) partLength)); [fileHandle seekToFileOffset: 0];

KS3InitiateMultipartUploadRequest * _muilt = [[KS3Client initialize] initiateMultipartUploadWithKey: @"500.txt"withBucket: @"blues111"inBucket: strBucketName acl: nil grantAcl: nil];
for (NSInteger i = 0; i < _partInter; i++) {
    NSData * data = nil;
    if (i == _partInter - 1) {
        data = [fileHandle readDataToEndOfFile];
    } 
    else {
        data = [fileHandle readDataOfLength: partLength]; 
        [fileHandle seekToFileOffset: partLength * (i + 1)];
    }
    KS3UploadPartRequest * req = [[KS3UploadPartRequest alloc] initWithMultipartUpload: _muilt];
    req.delegate = self;
    req.data = data;
    req.partNumber = (int32_t) i + 1;
    req.contentLength = data.length; [[KS3Client initialize] uploadPart: req];
}

// **** 分块上传的回调,每块上传结束后都会被调用
- (void) request: (KS3ServiceRequest * ) request didCompleteWithResponse: (KS3ServiceResponse * ) response {
    _upLoadCount++;
    if (_partInter == _upLoadCount) {
        KS3ListPartsRequest * req2 = [[KS3ListPartsRequest alloc] initWithMultipartUpload: _muilt];
        KS3ListPartsResponse * response2 = [[KS3Client initialize] listParts: req2];
        KS3CompleteMultipartUploadRequest * req = [[KS3CompleteMultipartUploadRequest alloc] initWithMultipartUpload: _muilt];
        NSLog(@" - - - - - %@", response2.listResult.parts);
        for (KS3Part * part in response2.listResult.parts) { [req addPartWithPartNumber: part.partNumber withETag: part.etag];
        } 
        [[KS3Client initialize] completeMultipartUpload: req];
    }
} 
- (void) request: (KS3ServiceRequest * ) request didFailWithError: (NSError * ) error {
    NSLog(@"error: %@", error.description);
}

Upload Manager

分块上传接口可以实现断点续传等功能,但是由于使用比较复杂,SDK提供了一个封装后的接口——Ks3UploadManager。

使用本接口首先需要初始化一个KS3UploadManager实例。

self.uploadManager = [KS3UploadManager sharedInstanceWithClient:[KS3Client initialize] authHandler:nil];

KS3UploadManager接受唯一参数是authHandler,此handler用于处理鉴权串签名,每次请求都会用本次请求的信息调用authHandler,handler方法内,请求鉴权服务器拿到签名串返回即可。

authHandler如果为nil,则需要在客户端设置AK、SK(这种方式不推荐)。设置方法为:[[KS3Client initialize] setCredentials:[[KS3Credentials alloc] initWithAccessKey:"YOUR_KS3_ACCESS_KEY" withSecretKey:"YOUR_KS3_SECRET_KEY"]];

实例创建好后,可以调用上传方法:

// 读取文件信息
NSString * strFilePath = [[NSBundle mainBundle] pathForResource: @"7.6M"ofType: @"mov"];
NSData * data = [NSData dataWithContentsOfFile: strFilePath];

KS3AccessControlList * acl = [[KS3AccessControlList alloc] init]; [acl setContronAccess: KingSoftYun_Permission_Public_Read];

// 创建一次开始分块的请求
KS3UploadRequest * uploadRequest = [[KS3UploadRequest alloc] initWithKey: @"uploadmanager/sample.mov"inBucket: kUploadBucketName acl: acl grantAcl: nil]; [uploadRequest setCompleteRequest]; [uploadRequest setStrKS3Token: [KS3Util getAuthorization: uploadRequest]];

// 开始上传
[self.uploadManager putData: data request: uploadRequest blockSize: 1 * kMB progress: ^(NSString * key, double percent) {
    NSLog(@"objectKey: %@, progress %lf", key, percent);
}
cancelSignal: ^BOOL(NSString * key) {
    return false; // 修改这里进行取消
}
complete: ^(KS3Upload * upload, KS3Response * response) {
    NSLog(@"uploadId: %@, response %@", upload.uploadId, response);
}
error: ^(KS3Upload * upload, NSError * error) {
    NSLog(@"uploadId: %@, error: %@", upload.uploadId, error);
}];

目前此接口只支持使用NSData作为参数进行上传。
