# sdk-java
|
||
|
||
|
||
sdk for java
|
||
|
||
SDK只依赖了三个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
|
||
|
||
|
||
```java
|
||
@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
|
||
|
||
```java
|
||
public class GetStoryRequest extends BaseRequest<GetStoryResponse> {
|
||
@Override
|
||
protected String method() {
|
||
return "alipay.story.find";
|
||
}
|
||
}
|
||
|
||
```
|
||
|
||
## 使用方式
|
||
|
||
```java
|
||
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(response);
|
||
} else {
|
||
System.out.println(response);
|
||
}
|
||
}
|
||
```
|
||
|
||
## 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
|
||
|
||
```java
|
||
@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);
|
||
}
|
||
}
|
||
```
