开发SDK

开放平台把接口开发完毕后,一般需要开发对应的SDK,提供给ISV。SOP提供了一个基础的SDK开发包

开发者可以在此基础上做开发,就拿sdk-java来说,具体步骤如下:

sdk-java

SDK依赖了三个jar包

  • okhttp.jar 用于网络请求
  • fastjson.jar 用于json处理
  • commons-logging.jar 日志处理

接口封装步骤

比如获取故事信息接口

  • 接口名:alipay.story.find
  • 版本号:1.0
  • 参数:name 故事名称
  • 返回信息
{
	"alipay_story_find_response": {
		"msg": "Success",
		"code": "10000",
		"name": "白雪公主",
		"id": 1,
		"gmtCreate": 1554193987378
	},
	"sign": "xxxxx"
}

针对这个接口,封装步骤如下:

1.在model包下新建一个类,定义业务参数

@Data
public class GetStoryModel {

    @JSONField(name = "name")
    private String name;
}

2.在response包下新建一个返回类GetStoryResponse,继承BaseResponse

里面填写返回的字段

@Data
public class GetStoryResponse extends BaseResponse {
    private Long id;
    private String name;
    private Date gmtCreate;
}

3.在request包下新建一个请求类,继承BaseRequest

BaseRequest中有个泛型参数,填GetStoryResponse类,表示这个请求对应的返回类。 重写method()方法,填接口名。

如果要指定版本号,可重写version()方法,或者后续使用request.setVersion(version)进行设置

public class GetStoryRequest extends BaseRequest<GetStoryResponse> {
    @Override
    protected String method() {
        return "alipay.story.find";
    }
}

可重写getRequestMethod()方法指定HTTP请求method,默认是POST。

@Override
protected RequestMethod getRequestMethod() {
    return RequestMethod.GET;
}

建议读请求用GET,写请求用POST

使用方式

String url = "http://localhost:8081/api";
String appId = "2019032617262200001";
String privateKey = "你的私钥";

// 声明一个就行
OpenClient client = new OpenClient(url, appId, privateKey);

// 标准用法
@Test
public void testGet() {
    // 创建请求对象
    GetStoryRequest request = new GetStoryRequest();
    // 请求参数
    GetStoryModel model = new GetStoryModel();
    model.setName("白雪公主");
    
    request.setBizModel(model);

    // 发送请求
    GetStoryResponse response = client.execute(request);

    if (response.isSuccess()) {
        // 返回结果
        System.out.println(String.format("成功!response:%s\n响应原始内容:%s", 
                JSON.toJSONString(response), response.getBody()));
    } else {
        System.out.println("错误,subCode:" + response.getSubCode() + ", subMsg:" + response.getSubMsg());
    }
}

使用方式2(懒人版)

如果不想添加Request,Response,Model。可以用这种方式,返回body部分是字符串,后续自己处理

body对应的是alipay_story_find_response部分

@Test
public void testLazy() {
    // 创建请求对象
    CommonRequest request = new CommonRequest("alipay.story.find");
    // 请求参数
    Map<String, Object> bizModel = new HashMap<>();
    bizModel.put("name", "白雪公主");
    request.setBizModel(bizModel);

    // 发送请求
    CommonResponse response = client.execute(request);

    if (response.isSuccess()) {
        // 返回结果,body对应的是alipay_story_find_response部分
        String body = response.getBody();
        JSONObject jsonObject = JSON.parseObject(body);
        System.out.println(jsonObject);
    } else {
        System.out.println(response);
    }
}

sdk-.net

接口封装步骤

比如获取故事信息接口

  • 接口名:alipay.story.find
  • 版本号:1.0
  • 参数:name 故事名称
  • 返回信息
{
	"alipay_story_find_response": {
		"msg": "Success",
		"code": "10000",
		"name": "白雪公主",
		"id": 1,
		"gmtCreate": 1554193987378
	},
	"sign": "xxxxx"
}

针对这个接口,封装步骤如下:

1.在Model包下新建一个类,定义业务参数

namespace SDKCSharp.Model
{
    public class GetStoryModel
    {
        /// <summary>
        /// 故事名称
        /// </summary>
        /// <value>The name.</value>
        [JsonProperty("name")]
        public string Name { get; set; }
    }
}

[JsonProperty("name")]是Newtonsoft.Json组件中的类,用于Json序列化,括号中的是参数名称。 类似于Java中的注解,@JSONField(name = "xx")

2.在Response包下新建一个返回类GetStoryResponse,继承BaseResponse

里面填写返回的字段

namespace SDKCSharp.Response
{
    public class GetStoryResponse: BaseResponse
    {
        [JsonProperty("id")]
        public int Id { get; set; }

        [JsonProperty("name")]
        public string Name { get; set; }

        [JsonProperty("gmt_create")]
        public string GmtCreate { get; set; }

    }
}

3.在Request文件夹下新建一个请求类,继承BaseRequest

BaseRequest中有个泛型参数,填GetStoryResponse类,表示这个请求对应的返回类。 重写GetMethod()方法,填接口名。

如果要指定版本号,可重写GetVersion()方法,或者后续使用request.Version = version进行设置

namespace SDKCSharp.Request
{
    public class GetStoryRequest : BaseRequest<GetStoryResponse>
    {
        public override string GetMethod()
        {
            return "alipay.story.find";
        }
    }

}

使用方式

class MainClass
{
    static string url = "http://localhost:8081/api";
    static string appId = "2019032617262200001";
    // 平台提供的私钥
    static string privateKey = "MIIEvQIBADANBgkqhkiG9w0BAQEFAASCBKcwggSjAgEAAoIBAQCXJv1pQFqWNA/++OYEV7WYXwexZK/J8LY1OWlP9X0T6wHFOvxNKRvMkJ5544SbgsJpVcvRDPrcxmhPbi/sAhdO4x2PiPKIz9Yni2OtYCCeaiE056B+e1O2jXoLeXbfi9fPivJZkxH/tb4xfLkH3bA8ZAQnQsoXA0SguykMRZntF0TndUfvDrLqwhlR8r5iRdZLB6F8o8qXH6UPDfNEnf/K8wX5T4EB1b8x8QJ7Ua4GcIUqeUxGHdQpzNbJdaQvoi06lgccmL+PHzminkFYON7alj1CjDN833j7QMHdPtS9l7B67fOU/p2LAAkPMtoVBfxQt9aFj7B8rEhGCz02iJIBAgMBAAECggEARqOuIpY0v6WtJBfmR3lGIOOokLrhfJrGTLF8CiZMQha+SRJ7/wOLPlsH9SbjPlopyViTXCuYwbzn2tdABigkBHYXxpDV6CJZjzmRZ+FY3S/0POlTFElGojYUJ3CooWiVfyUMhdg5vSuOq0oCny53woFrf32zPHYGiKdvU5Djku1onbDU0Lw8w+5tguuEZ76kZ/lUcccGy5978FFmYpzY/65RHCpvLiLqYyWTtaNT1aQ/9pw4jX9HO9NfdJ9gYFK8r/2f36ZE4hxluAfeOXQfRC/WhPmiw/ReUhxPznG/WgKaa/OaRtAx3inbQ+JuCND7uuKeRe4osP2jLPHPP6AUwQKBgQDUNu3BkLoKaimjGOjCTAwtp71g1oo+k5/uEInAo7lyEwpV0EuUMwLA/HCqUgR4K9pyYV+Oyb8d6f0+Hz0BMD92I2pqlXrD7xV2WzDvyXM3s63NvorRooKcyfd9i6ccMjAyTR2qfLkxv0hlbBbsPHz4BbU63xhTJp3Ghi0/ey/1HQKBgQC2VsgqC6ykfSidZUNLmQZe3J0p/Qf9VLkfrQ+xaHapOs6AzDU2H2osuysqXTLJHsGfrwVaTs00ER2z8ljTJPBUtNtOLrwNRlvgdnzyVAKHfOgDBGwJgiwpeE9voB1oAV/mXqSaUWNnuwlOIhvQEBwekqNyWvhLqC7nCAIhj3yvNQKBgQCqYbeec56LAhWP903Zwcj9VvG7sESqXUhIkUqoOkuIBTWFFIm54QLTA1tJxDQGb98heoCIWf5x/A3xNI98RsqNBX5JON6qNWjb7/dobitti3t99v/ptDp9u8JTMC7penoryLKK0Ty3bkan95Kn9SC42YxaSghzqkt+uvfVQgiNGQKBgGxU6P2aDAt6VNwWosHSe+d2WWXt8IZBhO9d6dn0f7ORvcjmCqNKTNGgrkewMZEuVcliueJquR47IROdY8qmwqcBAN7Vg2K7r7CPlTKAWTRYMJxCT1Hi5gwJb+CZF3+IeYqsJk2NF2s0w5WJTE70k1BSvQsfIzAIDz2yE1oPHvwVAoGAA6e+xQkVH4fMEph55RJIZ5goI4Y76BSvt2N5OKZKd4HtaV+eIhM3SDsVYRLIm9ZquJHMiZQGyUGnsvrKL6AAVNK7eQZCRDk9KQz+0GKOGqku0nOZjUbAu6A2/vtXAaAuFSFx1rUQVVjFulLexkXR3KcztL1Qu2k5pB6Si0K/uwQ=";


    // 声明一个就行
    static OpenClient client = new OpenClient(url, appId, privateKey);

    public static void Main(string[] args)
    {
        TestGet();
    }

    // 标准用法
    private static void TestGet()
    {
        // 创建请求对象
        GetStoryRequest request = new GetStoryRequest();
        // 请求参数
        GetStoryModel model = new GetStoryModel();
        model.Name = "白雪公主";
        request.BizModel = model;

        // 发送请求
        GetStoryResponse response = client.Execute(request);

        if (response.IsSuccess())
        {
            // 返回结果
            Console.WriteLine("故事名称:{0}", response.Name);
        }
        else
        {
            Console.WriteLine("错误, code:{0}, msg:{1}, subCode:{2}, subMsg:{3}", 
                response.Code, response.Msg, response.SubCode, response.SubMsg);
        }
    }

    
}

使用方式2(懒人版)

如果不想添加Request,Response,Model。可以用这种方式,返回data部分是Dictionary<string, object>,后续自己处理

// 懒人版,如果不想添加Request,Response,Model。可以用这种方式,返回Dictionary<string, object>,后续自己处理
private static void TestCommon()
{
    // 创建请求对象
    CommonRequest request = new CommonRequest("alipay.story.find");
    // 请求参数
    Dictionary<string, string> bizModel = new Dictionary<string, string>
    {
        ["name"] = "白雪公主"
    };

    request.BizModel = bizModel;

    // 发送请求
    CommonResponse response = client.Execute(request);

    if (response.IsSuccess())
    {
        // 返回结果
        string body = response.Body;
        Dictionary<string, object> dict = JsonUtil.ParseToDictionary(body);

        Console.WriteLine("Dictionary内容:");
        foreach (var item in dict)
        {
            Console.WriteLine("{0}:{1}", item.Key, item.Value);
        }
    }
    else
    {
        Console.WriteLine("错误, code:{0}, msg:{1}, subCode:{2}, subMsg:{3}",
            response.Code, response.Msg, response.SubCode, response.SubMsg);
    }
}
