Performing a Streaming Upload

Streaming upload uses OBSPutObjectWithDataRequest to obtain the data source. You can call putObject to upload the data streams to OBS. Sample code is as follows:

static OBSClient *client;
NSString *endPoint = @"https://your-endpoint";
// Hard-coded or plaintext AK and SK are risky. For security purposes, encrypt your AK and SK before storing them in the configuration file or environment variables. In this example, the AK and SK are stored in environment variables. Before running the code in this example, configure environment variables AccessKeyID and SecretAccessKey.
// Obtain an AK/SK pair on the management console. For details, see https://support.huaweicloud.com/intl/en-us/usermanual-ca/ca_01_0003.html.
char* ak_env = getenv("AccessKeyID");
char* sk_env = getenv("SecretAccessKey");
if (ak_env == NULL || sk_env == NULL) {
    NSLog(@"Error: AccessKeyID or SecretAccessKey environment variable not set");
    return;
}
NSString *AK = [NSString stringWithUTF8String:ak_env];
NSString *SK = [NSString stringWithUTF8String:sk_env];

// Initialize identity authentication.
OBSStaticCredentialProvider *credentialProvider = [[OBSStaticCredentialProvider alloc] initWithAccessKey:AK secretKey:SK];
    
//Initialize service configuration.
OBSServiceConfiguration *conf = [[OBSServiceConfiguration alloc] initWithURLString:endPoint credentialProvider:credentialProvider];
    
// Initialize an instance of OBSClient.
client = [[OBSClient alloc] initWithConfiguration:conf];
    
// Upload a character string in streaming mode.
OBSPutObjectWithDataRequest *request = [[OBSPutObjectWithDataRequest alloc]initWithBucketName:@"bucketname" objectKey:@"objectname" uploadData:[@"hello" dataUsingEncoding:NSUTF8StringEncoding]];
    
// Query the upload progress.
request.uploadProgressBlock = ^(int64_t bytesSent, int64_t totalBytesSent, int64_t totalBytesExpectedToSend) {
    NSLog(@"%0.1f%%",(float)floor((totalBytesExpectedToSend > 0) ? (totalBytesSent*10000/totalBytesExpectedToSend) : 0)/100);
};
    
[client putObject:request completionHandler:^(OBSPutObjectResponse *response, NSError *error){
    NSLog(@"%@",response);
}];

static OBSClient *client;
NSString *endPoint = @"https://your-endpoint";
// Hard-coded or plaintext AK and SK are risky. For security purposes, encrypt your AK and SK before storing them in the configuration file or environment variables.

// Obtain an AK/SK pair on the management console. For details, see https://support.huaweicloud.com/intl/en-us/usermanual-ca/ca_01_0003.html.
char* ak_env = getenv("AccessKeyID");
char* sk_env = getenv("SecretAccessKey");
if (ak_env == NULL || sk_env == NULL) {
    NSLog(@"Error: AccessKeyID or SecretAccessKey environment variable not set");
    return;
}
NSString *AK = [NSString stringWithUTF8String:ak_env];
NSString *SK = [NSString stringWithUTF8String:sk_env];

// Initialize identity authentication.
OBSStaticCredentialProvider *credentialProvider = [[OBSStaticCredentialProvider alloc] initWithAccessKey:AK secretKey:SK];
    
//Initialize service configuration.
OBSServiceConfiguration *conf = [[OBSServiceConfiguration alloc] initWithURLString:endPoint credentialProvider:credentialProvider];
    
// Initialize an instance of OBSClient.
client = [[OBSClient alloc] initWithConfiguration:conf];
    
// Upload a network stream in streaming mode.
OBSPutObjectWithDataRequest *request = [[OBSPutObjectWithDataRequest alloc] initWithBucketName:@"bucketname" objectKey:@"objectname" uploadDataURL:[NSURL URLWithString:@"https://your-url" ]];
    
// Query the upload progress.
request.uploadProgressBlock = ^(int64_t bytesSent, int64_t totalBytesSent, int64_t totalBytesExpectedToSend) {
    NSLog(@"%0.1f%%",(float)floor((totalBytesExpectedToSend > 0) ? (totalBytesSent*10000/totalBytesExpectedToSend) : 0)/100);
};
    
[client putObject:request completionHandler:^(OBSPutObjectResponse *response, NSError *error){
   NSLog(@"%@",response);
}];

Uploading a File Stream

static OBSClient *client;
NSString *endPoint = @"https://your-endpoint";
// Hard-coded or plaintext AK and SK are risky. For security purposes, encrypt your AK and SK before storing them in the configuration file or environment variables. In this example, the AK and SK are stored in environment variables. Before running the code in this example, configure environment variables AccessKeyID and SecretAccessKey.
// Obtain an AK/SK pair on the management console. For details, see https://support.huaweicloud.com/intl/en-us/usermanual-ca/ca_01_0003.html.
char* ak_env = getenv("AccessKeyID");
char* sk_env = getenv("SecretAccessKey");
if (ak_env == NULL || sk_env == NULL) {
    NSLog(@"Error: AccessKeyID or SecretAccessKey environment variable not set");
    return;
}
NSString *AK = [NSString stringWithUTF8String:ak_env];
NSString *SK = [NSString stringWithUTF8String:sk_env];

// Initialize identity authentication.
OBSStaticCredentialProvider *credentialProvider = [[OBSStaticCredentialProvider alloc] initWithAccessKey:AK secretKey:SK];
    
//Initialize service configuration.
OBSServiceConfiguration *conf = [[OBSServiceConfiguration alloc] initWithURLString:endPoint credentialProvider:credentialProvider];
    
// Initialize an instance of OBSClient.
client = [[OBSClient alloc] initWithConfiguration:conf];
    
NSString *filePath = [[NSBundle mainBundle]pathForResource:@"fileName" ofType:@"Type"];
// Upload a file stream.
NSData *uploadData = [NSData dataWithContentsOfFile:filePath];
OBSPutObjectWithDataRequest *request = [[OBSPutObjectWithDataRequest alloc]initWithBucketName:@"bucketname" objectKey:@"test/image1" uploadData:uploadData ];
    
// Query the upload progress.
request.uploadProgressBlock = ^(int64_t bytesSent, int64_t totalBytesSent, int64_t totalBytesExpectedToSend) {
   NSLog(@"%0.1f%%",(float)floor((totalBytesExpectedToSend > 0) ? (totalBytesSent*10000/totalBytesExpectedToSend) : 0)/100);
};
    
[client putObject:request completionHandler:^(OBSPutObjectResponse *response, NSError *error){
    NSLog(@"%@",response);
}];

• To upload local files, file-based upload is recommended.
• To upload large files, multipart upload is recommended.
• The content to be uploaded cannot exceed 5 GB.
