(Objective-C) OSS Download String (Alibaba Cloud)
Demonstrates how to download a textual object into a string variable.
The Chilkat S3 functions in the HTTP class are compatible with Alibaba Cloud's OSS service.
#import <CkoHttp.h>
#import <NSString.h>
// This example assumes the Chilkat API to have been previously unlocked.
// See Global Unlock Sample for sample code.
CkoHttp *http = [[CkoHttp alloc] init];
// Insert your AccessKey ID here:
http.AwsAccessKey = @"access-key";
// Insert your AccessKey Secret here:
http.AwsSecretKey = @"secret-key";
// To download from a bucket located in a different region, use the endpoint for that region, such as "oss-cn-hangzhou.aliyuncs.com "
// See Alibaba Object Storage Service Regions and Endpoints
http.AwsEndpoint = @"oss-us-east-1.aliyuncs.com";
NSString *bucketName = @"chilkat";
NSString *objectName = @"orchard.json";
// This is the byte representation of the text file downloaded from Aliyun.
// It must be specified to allow Chilkat to correctly interpret the bytes as characters.
NSString *charset = @"utf-8";
NSString *fileContents = [http S3_DownloadString: bucketName objectName: objectName charset: charset];
if (http.LastMethodSuccess != YES) {
NSLog(@"%@",http.LastErrorText);
}
else {
NSLog(@"%@",fileContents);
NSLog(@"%@",@"Success.");
}
