1.引入阿里的SDK

2. 搬一下java 的代码

DefaultProfile profile = DefaultProfile.GetProfile(
"cn-hangzhou", //默认
"YourAccessKeyID", //您的Access Key ID
"YourAccessKeySecret");

DefaultProfile profile = DefaultProfile.GetProfile(
"cn-hangzhou", //默认
"YourAccessKeyID", //您的Access Key ID
"YourAccessKeySecret");

//IClientProfile client = DefaultProfile.GetProfile("cn-hangzhou", KeyID, KeySecret);
IAcsClient client = new DefaultAcsClient(profile);

//您在控制台上创建的、采用RPBasic认证方案的认证场景标识, 创建方法：https://help.aliyun.com/document_detail/59975.html
string biz = "YourRPBasicBiz";

//认证ID, 由使用方指定, 发起不同的认证任务需要更换不同的认证ID
string ticketId = Guid.NewGuid().ToString();

//认证token, 表达一次认证会话
string token = null;

//-1 未认证, 0 认证中, 1 认证通过, 2 认证不通过
int statusCode = -1;

//1. 服务端发起认证请求, 获取到token
//GetVerifyToken接口文档：https://help.aliyun.com/document_detail/57050.htm

GetVerifyTokenRequest getVerifyTokenRequest = new GetVerifyTokenRequest();
getVerifyTokenRequest.Biz = biz;
getVerifyTokenRequest.TicketId = ticketId;
getVerifyTokenRequest.Method = MethodType.POST;
var ss = new
{
Name= "张三",
IdentificationNumber = "330110201711110101",
IdCardFrontPic = "http://image-demo.img-cn-hangzhou.aliyuncs.com/example.jpg",
IdCardBackPic = "base64:///9j/4AAQSkZJRgABAQEASABIAAD/2..."
};
getVerifyTokenRequest.Binding = JsonConvert.SerializeObject(ss);
//通过binding参数传入业务已经采集的认证资料，其中姓名、身份证号为必要字段
//若需要binding图片资料，请控制单张图片大小在 2M 内，避免拉取超时
// getVerifyTokenRequest.setBinding("{\"Name\": \"张三\",\"IdentificationNumber\": \"330110201711110101\"}");
//友情提示:如果JSON中需要带换行符,请参照标准的JSON协议对换行符的要求,比如短信内容中包含\r\n的情况在JSON中需要表示成\\r\\n,否则会导致JSON在服务端解析失败
// request.TemplateParamJson = "[{\"name\":\"Tom\", \"code\":\"123\"},{\"name\":\"Jack\", \"code\":\"456\"}]";

//GetEndpoints
// GetVerifyTokenResponse response = client.GetEndpoints(getVerifyTokenRequest);
// token = response.getData().getVerifyToken().getToken(); //token默认30分钟时效，每次发起认证时都必须实时获取

try
{//SetCredentialsProvider
// GetVerifyTokenResponse response = client.getAcsResponse(getVerifyTokenRequest);
GetVerifyTokenResponse response = client.GetAcsResponse(getVerifyTokenRequest);
// token = response.getData().getVerifyToken().getToken();
token = response.Data.VerifyToken.Token;//token默认30分钟时效，每次发起认证时都必须实时获取
}
catch (ServerException e)
{
Console.WriteLine(e.ErrorCode);
}

//2. 服务端将认证URL(带token)传递给H5前端
//3. H5前端跳转认证URL
//4. 用户按照认证H5流程页面的指引，提交认证资料
//5. 认证流程结束跳转指定的重定向URL(指定方法参看：https://help.aliyun.com/document_detail/58644.html?#H5Server)
//6. 服务端查询认证状态(建议以服务端调接口确认的为准)
//GetStatus接口文档：https://help.aliyun.com/document_detail/57049.html

GetStatusRequest getStatusRequest = new GetStatusRequest();

getStatusRequest.Biz = biz;
getStatusRequest.TicketId = ticketId;

try
{
GetStatusResponse response = client.GetAcsResponse(getStatusRequest);
statusCode = Convert.ToInt32(response.Data.StatusCode);
}
catch (ServerException e)
{
Console.WriteLine(e.ErrorCode);
}

//7. 服务端获取认证资料
//GetMaterials接口文档：https://help.aliyun.com/document_detail/57641.html

GetMaterialsRequest getMaterialsRequest = new GetMaterialsRequest();
getMaterialsRequest.Biz = biz;
getMaterialsRequest.TicketId = ticketId;
if (1 == statusCode || 2 == statusCode)
{
//认证通过or认证不通过
try
{
GetMaterialsResponse response = client.GetAcsResponse(getMaterialsRequest);
//后续业务处理
}
catch (ServerException e)
{
Console.WriteLine(e.ErrorCode);
}

}

3.未完待续
