Performing a File-Based Upload

File-based upload uses local files as the data source of objects. Sample code is as follows:

static OBSClient *client;
NSString *endPoint = @"your-endpoint";

// Hard-coded or plaintext AK/SK are risky. For security purposes, encrypt your AK/SK and store them in the configuration file or environment variables. In this example, the AK/SK are stored in environment variables for identity authentication. Before running this example, configure environment variables AccessKeyID and SecretAccessKey.
// Obtain an AK/SK pair on the management console. For details, see https://support.huaweicloud.com/eu/usermanual-ca/ca_01_0003.html.
char* ak_env = getenv("AccessKeyID");
char* sk_env = getenv("SecretAccessKey");
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];
// Specify the name and type of the file to be uploaded.
NSString *filePath = [[NSBundle mainBundle]pathForResource:@"fileName" ofType:@"Type"];
// Upload a file.
OBSPutObjectWithFileRequest *request = [[OBSPutObjectWithFileRequest alloc]initWithBucketName:@"bucket-ios-test02" objectKey:@"imageWithFile" uploadFilePath:filePath];
// Enable background upload. When an application is switched to the background, the ongoing upload continues.
request.background = YES; 
    
// Query the upload progress.
request.uploadProgressBlock = ^(int64_t bytesSent, int64_t totalBytesSent, int64_t totalBytesExpectedToSend) {
    NSLog(@"%0.1f%%",(float)floor(totalBytesSent*10000/totalBytesExpectedToSend)/100);
};
    
[client putObject:request completionHandler:^(OBSPutObjectResponse *response, NSError *error){
    // Determine the error status.
    if(error){
       // Print error information.
        NSLog(@"Failed to upload the file.");
        NSLog(@"%@",error);
    }
// If the file is uploaded successfully, the response status code 200 is returned and printed.
    if([response.statusCode isEqualToString:@"200"]){
        NSLog(@"The file is successfully uploaded.");
        NSLog(@"%@",response);
        NSLog(@"%@",response.etag);
    } 
}];
