PAYJS-CSharp-SDK

本项目为PAYJS API接口的C#封装。文档地址：https://help.payjs.cn/

说明

为了简化sdk，本项目仅有一个cs类文件，封装了payjs常用接口的调用、生成sign、验sign、发送请求等功能。

不包含响应结果的格式化功能，需要自行处理json字符串，推荐使用https://github.com/JamesNK/Newtonsoft.Json

src目录为类库源文件，可以引入自己的项目中，支持ASP.NET、ASP.NET Core、NetCore WebAPI等环境

快速使用

1、初始化

Payjs pay = new Payjs("YOUR MCHID", "YOUR KEY");

2、二维码

Dictionary<string, string> param = new Dictionary<string, string>();
param["total_fee"] = "1";
param["out_trade_no"] = DateTime.Now.Ticks.ToString();
param["body"] = "test";
param["attch"] = "user id";
param["notify_url"] = "YOUR notify_url";

//返回原始json字符串
string jsonString = pay.native(param);

3、收银台

Dictionary<string, string> param = new Dictionary<string, string>();
param["total_fee"] = "1";
param["out_trade_no"] = DateTime.Now.Ticks.ToString();
param["body"] = "test";
param["attch"] = "user id";
param["notify_url"] = "YOUR notify_url";
param["callback_url"] = "YOUR callback_url";

//返回收银台地址，直接跳转到此地址即可
string url = pay.cashier(param);

4、JSAPI

Dictionary<string, string> param = new Dictionary<string, string>();
param["total_fee"] = "1";
param["out_trade_no"] = DateTime.Now.Ticks.ToString();
param["body"] = "test";
param["attch"] = "user id";
param["notify_url"] = "YOUR notify_url";
param["openid"] = "user's openid";//获取用户openid：https://help.payjs.cn/api-lie-biao/huo-qu-openid.html

//返回原始json字符串
string jsonString = pay.jsapi(param);

5、刷卡支付

Dictionary<string, string> param = new Dictionary<string, string>();
param["total_fee"] = "1";
param["out_trade_no"] = DateTime.Now.Ticks.ToString();
param["body"] = "test";
param["attch"] = "user id";
param["auth_code"] = "YOUR auth_code";


//返回原始json字符串
string jsonString = pay.micropay(param);

6、订单查询

Dictionary<string, string> param = new Dictionary<string, string>();
param["payjs_order_id"] = "2018xxxxxxx";

//返回原始json字符串
string jsonString = pay.check(param);

7、关闭订单

Dictionary<string, string> param = new Dictionary<string, string>();
param["payjs_order_id"] = "2018xxxxxxx";

//返回原始json字符串
string jsonString = pay.close(param);

8、退款

Dictionary<string, string> param = new Dictionary<string, string>();
param["payjs_order_id"] = "2018xxxxxxx";

//返回原始json字符串
string jsonString = pay.refund(param);

9、获取用户资料

Dictionary<string, string> param = new Dictionary<string, string>();
param["openid"] = "xxxxxxxxxxx";

//返回原始json字符串
string jsonString = pay.user(param);

10、获取商户资料

//返回原始json字符串
string jsonString = pay.info(new Dictionary<string, string>());

11、PAYJS回调请求的验签

//param参数为PAYJS服务器POST过来的数据，根据自己项目中所用的框架获取POST数据后，转为Dictionary<string,string>类型传入notifyCheck方法

//返回是否验证成功
bool issuccess = pay.notifyCheck(param);

12、人脸支付

Dictionary<string, string> param = new Dictionary<string, string>();
param["total_fee"] = "1";
param["out_trade_no"] = DateTime.Now.Ticks.ToString();
param["body"] = "test";
param["attch"] = "user id";
param["face_code"] = "YOUR face_code";
param["openid"] = "user's openid";

string jsonString = pay.facepay(param);

13、MWEB支付（H5支付)

Dictionary<string, string> param = new Dictionary<string, string>();
param["total_fee"] = "1";
param["out_trade_no"] = DateTime.Now.Ticks.ToString();
param["body"] = "test";
param["attch"] = "user id";
param["callback_url"] = "自定义返回跳转的URL";
param["notify_url"] = "YOUR notify_url";

string jsonString = pay.mweb(param);

14、撤销订单

Dictionary<string, string> param = new Dictionary<string, string>();
param["payjs_order_id"] = "2018xxxxxxx";

//返回原始json字符串
string jsonString = pay.reverse(param);

Dictionary<string, string> param = new Dictionary<string, string>();

//返回原始json字符串
string jsonString = pay.complaint(param);

16、银行编码查询

Dictionary<string, string> param = new Dictionary<string, string>();
param["bank"] = "xxxxxx";

//返回原始json字符串
string jsonString = pay.bank(param);
