【已解决阿里云短信】aliyuncs.exceptions.ClientException: SDK.ServerUnreachable : Server unreachable: java.net

1 以下代码亲测有效

public static void main(String[] args) throws ClientException {
	// TODO 一下均为官网代码：改这里
	DefaultProfile profile = DefaultProfile.getProfile("cn-hangzhou", "LTAI4GCgFCceHBmPekYTxS5W", "mjaXuLx392kbwOWRZ5R3JuZCqlTh1w");
	IAcsClient client = new DefaultAcsClient(profile);
	CommonRequest request = new CommonRequest();
	// 请求类型：必填 固定值
	request.setMethod(MethodType.POST);
	// 产品域名：必填 固定值
	request.setDomain("dysmsapi.aliyuncs.com");
	// 版本：必填 固定值
	request.setVersion("2017-05-25");
	// 动作：必填 固定值
	request.setAction("SendSms");
	// 必填 固定值
	request.putQueryParameter("RegionId", "cn-hangzhou");
	// 手机号 TODO 改这里
	request.putQueryParameter("PhoneNumbers", "135********");
	// 签名 TODO 改这里
	request.putQueryParameter("SignName", "****");
	// 模板 TODO 改这里 验证码模板只能发送[a-zA-Z0-9]
	request.putQueryParameter("TemplateCode", "****");
	// 发送的内容 TODO 改这里
	String value = "1234";
	request.putQueryParameter("TemplateParam", "{"code": ""+value+"" }");
	try {
		CommonResponse response = client.getCommonResponse(request);
		System.out.println(response.getData());
	} catch (ServerException e) {
		e.printStackTrace();
	} catch (ClientException e) {
		e.printStackTrace();
	}
