OSS Upload String (Alibaba Cloud)

See more Alibaba Cloud OSS Examples

Demonstrates how to upload the contents of a string to an AliCloud OSS bucket.

The Chilkat S3 functions in the HTTP class are compatible with Alibaba Cloud's OSS service.

Objective-C

#import <CkoHttp.h>
#import <NSString.h>
#import <CkoXml.h>

BOOL success = NO;

// 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 upload to 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";
NSString *contentType = @"application/json";

http.KeepResponseBody = YES;

// Let's say we have JSON in a string and want to upload it to a file in Aliyun..
NSString *jsonStr = @"{ \"orchard\": \"apple\" }";

// The charset indicates the byte representation of what is uploaded.
// If needed, Chilkat will internally convert to the desired byte representation before uploading.
NSString *charset = @"utf-8";
success = [http S3_UploadString: jsonStr charset: charset contentType: contentType bucketName: bucketName ObjectName: objectName];

if (success != YES) {
    NSLog(@"%@",http.LastErrorText);

    CkoXml *xml = [[CkoXml alloc] init];
    [xml LoadXml: http.LastResponseBody];
    NSLog(@"%@",[xml GetXml]);
}

    NSLog(@"%@",@"String uploaded.");
