本文主要介绍如何从内存中或从本地磁盘上传文件(Object)。
从内存中上传文件
以下代码用于从内存中上传内容到目标存储空间examplebucket中exampledir目录下的exampleobject.txt文件。
#include <alibabacloud/oss/OssClient.h> using namespace AlibabaCloud::OSS; int main(void) { /* 初始化OSS账号信息 */ std::string AccessKeyId = "yourAccessKeyId"; std::string AccessKeySecret = "yourAccessKeySecret"; std::string Endpoint = "yourEndpoint"; /* 填写Bucket名称,例如examplebucket */ std::string BucketName = "examplebucket"; /* 填写文件完整路径,例如exampledir/exampleobject.txt。文件完整路径中不能包含Bucket名称 */ std::string ObjectName = "exampledir/exampleobject.txt"; /* 初始化网络等资源 */ InitializeSdk(); ClientConfiguration conf; OssClient client(Endpoint, AccessKeyId, AccessKeySecret, conf); std::shared_ptr<std::iostream> content = std::make_shared<std::stringstream>(); *content << "Thank you for using Alibaba Cloud Object Storage Service!"; PutObjectRequest request(BucketName, ObjectName, content); /*(可选)请参见如下示例设置存储类型及访问权限ACL* / //request.MetaData().addHeader("x-oss-object-acl", "private"); //request.MetaData().addHeader("x-oss-storage-class", "Standard"); /* 上传文件 */ auto outcome = client.PutObject(request); if (!outcome.isSuccess()) { /* 异常处理 */ std::cout << "PutObject fail" << ",code:" << outcome.error().Code() << ",message:" << outcome.error().Message() << ",requestId:" << outcome.error().RequestId() << std::endl; ShutdownSdk(); return -1; } /* 释放网络等资源 */ ShutdownSdk(); return 0; }
上传本地文件
以下代码用于上传本地D:\\localpath路径下的examplefile.txt到目标存储空间examplebucket中exampledir目录下的exampleobject.txt文件。
#include <alibabacloud/oss/OssClient.h> #include <fstream> using namespace AlibabaCloud::OSS; int main(void) { /* 初始化OSS账号信息 */ std::string AccessKeyId = "yourAccessKeyId"; std::string AccessKeySecret = "yourAccessKeySecret"; std::string Endpoint = "yourEndpoint"; /* 填写Bucket名称,例如examplebucket */ std::string BucketName = "examplebucket"; /* 填写文件完整路径,例如exampledir/exampleobject.txt。文件完整路径中不能包含Bucket名称 */ std::string ObjectName = "exampledir/exampleobject.txt"; /* 初始化网络等资源 */ InitializeSdk(); ClientConfiguration conf; OssClient client(Endpoint, AccessKeyId, AccessKeySecret, conf); /* 填写本地文件完整路径,例如D:\\localpath\\examplefile.txt,其中localpath为本地文件examplefile.txt所在本地路径 */ std::shared_ptr<std::iostream> content = std::make_shared<std::fstream>("D:\\localpath\\examplefile.txt", std::ios::in | std::ios::binary); PutObjectRequest request(BucketName, ObjectName, content); /*(可选)请参见如下示例设置存储类型及访问权限ACL */ //request.MetaData().addHeader("x-oss-object-acl", "private"); //request.MetaData().addHeader("x-oss-storage-class", "Standard"); auto outcome = client.PutObject(request); if (!outcome.isSuccess()) { /* 异常处理 */ std::cout << "PutObject fail" << ",code:" << outcome.error().Code() << ",message:" << outcome.error().Message() << ",requestId:" << outcome.error().RequestId() << std::endl; ShutdownSdk(); return -1; } /* 释放网络等资源 */ ShutdownSdk(); return 0; }
