aliyun-openapi-net-sdk's Introduction

Open API SDK for .Net developers

Requirements

支持 .Net Freamwork 4.5 及以上版本；
下载SDK 把 aliyun-net-sdk-core.dll 和相应产品的 .dll 文件添加引用到项目中。

Example

using Aliyun.Acs.Core;
using Aliyun.Acs.Core.Exceptions;
using Aliyun.Acs.Core.Profile;
using Aliyun.Acs.Ecs.Model.V20140526;
using System;
 
class Sample
{
static void Main(string[] args)
{
TestDescribeInstanceAttribute();
}
 
private static void TestDescribeInstanceAttribute()
{
 
IClientProfile clientProfile = DefaultProfile.GetProfile("cn-hangzhou", "<your access key id>", "<your access key secret>");
DefaultAcsClient client = new DefaultAcsClient(clientProfile);
 
DescribeInstanceAttributeRequest request = new DescribeInstanceAttributeRequest();
request.InstanceId = "<your instances id>";
try
{
DescribeInstanceAttributeResponse response = client.GetAcsResponse(request);
Console.Write(response.InstanceId);
}
catch (ServerException e)
{
Console.WriteLine(e.ErrorCode);
Console.WriteLine(e.ErrorMessage);
}
catch (ClientException e)
{
Console.WriteLine(e.ErrorCode);
Console.WriteLine(e.ErrorMessage);
}
}
}

Questions

怎么判断API调用成功？

通过catch异常判断API是否调用成功，当 API 的 http status>=200 且 <300 表示API调用成功；当http status>=300且<500 SDK抛ClientException；当http status >=500 SDK 抛 ServerException
IClientProfile clientProfile = DefaultProfile.GetProfile("< your request regionid >", "< your access key id >", "< your access key secret >");

此处的regionid参数指你需要操作的region的id，例如要操作杭州region，则regionid=cn-hangzhou；默认填cn-hangzhou.
