本章講的是兩種上傳文件到oss的方式
我使用的是vs2017 IDE
安裝C++SDK的過程：
安裝 CMake。打開 cmd 進入 SDK 文件目錄，創建 build 文件夾，運行cmake …生成所需文件，如果要構建 x64 體系結構，可以使用命令 cmake -A x64 …來實現。再用 Visual Studio 打開 alibabacloud-oss-cpp-sdk.sln 生成解決方案。生成lib和dll文件即可。
依賴庫分debug和release版本。
需要分別編譯。
導庫：
包含目錄
庫目錄：
庫名：
#include <iostream>
#include <alibabacloud/oss/OssClient.h> //oss庫
using namespace std;
using namespace AlibabaCloud::OSS;
void uploadoss(String &str)
{
/* 初始化OSS賬號信息 */
std::string AccessKeyId = "*****";
std::string AccessKeySecret = "****";
std::string Endpoint = "oss-cn-beijing.aliyuncs.com"; //圖片訪問地址域名地址
std::string BucketName = "yourBucketName"; //你的bucket名字
std::string ObjectName = "images/" + str; //oss文件+文件名
/* 初始化網絡等資源 */
InitializeSdk();
ClientConfiguration conf;
OssClient client(Endpoint, AccessKeyId, AccessKeySecret, conf);
/* 上傳文件 */
auto outcome = client.PutObject(BucketName, ObjectName, "../1.jpg");//本地文件地址
if (!outcome.isSuccess()) {
/* 異常處理 */
std::cout << "CreateBucket fail" <<
",code:" << outcome.error().Code() <<
",message:" << outcome.error().Message() <<
",requestId:" << outcome.error().RequestId() << std::endl;
ShutdownSdk();
return;
}else
{
cout<<"send successful!"<<endl;
}
/* 釋放網絡等資源 */
ShutdownSdk();
return;
}
//內存上傳
void uploadoss(String &picname, stringstream &picstream)
{
/* 初始化OSS賬號信息 */
std::string AccessKeyId = "****";
std::string AccessKeySecret = "***";
std::string Endpoint = "oss-cn-beijing.aliyuncs.com"; //圖片訪問地址域名地址
std::string BucketName = "yourBucketName"; //
std::string ObjectName = "images/" + picname;
/* 初始化網絡等資源 */
InitializeSdk();
ClientConfiguration conf;
OssClient client(Endpoint, AccessKeyId, AccessKeySecret, conf);
std::shared_ptr<std::iostream> content = std::make_shared<std::stringstream>();
*content << picstream.str();
PutObjectRequest request(BucketName, ObjectName, content);
/*（可選）請參見如下示例設置存儲類型及訪問權限ACL* /
//request.MetaData().addHeader("x-oss-object-acl", "private");
//request.MetaData().addHeader("x-oss-storage-class", "Standard");
/* 上傳文件 */
auto outcome = client.PutObject(request);
if (!outcome.isSuccess()) {
/* 異常處理 */
std::cout << "CreateBucket fail" <<
",code:" << outcome.error().Code() <<
",message:" << outcome.error().Message() <<
",requestId:" << outcome.error().RequestId() << std::endl;
ShutdownSdk();
return;
}else
{
cout << "send successful! " << endl;
}
/* 釋放網絡等資源 */
ShutdownSdk();
return;
}
int main()
{
//本地上傳
String picname = "filename.jpg";
uploadoss(picname);
//內存上傳
stringstream liu;
for(int i=0;i<10;i++)
{
liu<<i;
}
//至此，信息已經在這個sstream流裏;
String picname2 = "1.txt";
uploadoss(picname2,liu);
return 0;
}
至此。成功上傳oss
在運行文件目錄下添加下面兩個dll，否則會彈出缺少dll
如：Debug目錄下
下面再給一個QT使用oss的配置教程：
注意要版本一致。和vs使用類似，我就不多說了。
我就只講配置使用的部分：
需要添加4個lib和3個文件使用路徑：
下面給一個pro：

我使用的例子是x64+release編譯的。你們應用的時候需要生成所對應的阿里雲oss-lib。
