# 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 for java |
||||||
|
|
||||||
|
开放平台对应的sdk，适用于Android。SDK依赖了三个jar包 |
||||||
|
|
||||||
|
- okhttp.jar 用于网络请求 |
||||||
|
- fastjson-android.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"; // zuul |
||||||
|
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); |
||||||
|
} |
||||||
|
} |
||||||
|

sdk for java |

|
|

开放平台对应的sdk，适用于Android。SDK只依赖了三个jar包 |

"id": 1, |

"gmtCreate": 1554193987378 |

"sign": "xxxxx" |
||||||
|
} |
||||||

||||||
|
|
||||||
|
1.在`model`包下新建一个类，定义业务参数 |

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); |
||||||
|
} |
||||||
|
} |
||||||
|
``` |

|
* <li>URL-safe mode: Default off.</li> |
||||||
|
* <li>Line length: Default 76. Line length that aren't multiples of 4 will still essentially end up being multiples of |

回忆起 20多年来我们一起走过的日子，我就感到特别温馨、特别甜蜜。你第一次闯入我生命中的情景，仿佛就在眼前……第一次偶然相遇是1996年5月，那是一个夏风习习的夜晚，我刚从工地回来，同事就邀我一起去城建学院跳舞，踏进舞厅的一瞬间，在暗淡温柔的霓虹灯下，你那清新脱俗的靓影一下子就深深的嵌入了我的心里。 |

记得大学时代，李春波的歌曲“小芳”响彻校园，那个叫小芳的村里姑娘，也深深的烙进了我的心底，成了我少年时的梦中偶像。二十多年来，我一直期盼着找到一个象歌曲中所唱的长得好看又善良、有着一双美丽的大眼睛和两条粗辫子的姑娘做我的爱人，但苦苦寻觅却难见芳踪，谁知众里寻她千百度，蓦然回首，那人却在灯火阑珊处……你就这样俏生生的突然出现在我眼前。当时，你穿着浅绿色的衬衣，正在与一位女同学翩翩起舞，两条又粗又长的辫子在身后灵巧的晃动。一曲终了，我急忙挤到你身边请你跳舞。当时的我还不太会跳舞，还好是一首慢四舞曲，我才没出洋相。拥着你在舞厅漫步，因为心情特别激动，又怕舞步不熟踩到你脚，我眼睛始终盯着脚下，不敢正视你的目光；好不容易平复心情与你搭讪，才打探到你是教育学院的学生舞曲就结束了。后面的舞曲不是我不会跳就是被你那“讨厌”的女同学捷足先登了，始终没有机会再次与你共舞，但我的心已经完完全全的被你牵走了。同事周云看我不再跳舞、心事重重的，就问我为什么，得知我心事后，自告奋勇的说下一曲他去邀请你同学，让我有机会请你跳舞。可没想到我那同事的“光头”会把你们吓跑，让上天给我们安排的第一次相遇就这样擦肩而过。 |

红与青 时光如流水般，在我面前一闪而过，但我却只能暗暗叹息。 台灯下，小桌前，我坐在那儿，目光停在桌子上的那一个西瓜面前。十几年前的往事仿佛就在昨日。 小时候，我们兄弟几个围坐在一张破破的桌子前。一个勺子，半个西瓜，大家围着轮流舀着吃，大家的目光都聚焦在西瓜上，也许只有在这一刻，我们才不会那样的打闹。我们都想吃最中间的部分，最红的，最甜的部分，可是又如同大人世界般，我们显得那样腼腆。最后，总是你一小口我一小口，把那中间红红的果肉吞进肚子里，更埋下友谊的种子。 日子深一脚浅一脚的过，学习似乎成了我们唯一的公同语言，我们也从一个被别人称为“造反派”的顽童变为一个学子。甚至有时，在哪儿碰见也只会向对方点点头，丝毫没有了小时烈日下奔跑的情谊。家里的那张破破的桌子也不知去向，取而代之的是一张豪华的青瓷桌…… 小学毕业后那年暑假的最后一天，刚刚步入六年级的他们来送别我，我们围坐在桌边，夏日的炎热似乎把我们所有要诉说的话都给憋了回去，我们都沉默着。冰爽的西瓜成了我们释放的对象，我们不再像小时那样子吃西瓜，所有的西瓜都被切成了片，有红，有青。红红的那部分就在最上面，我们之间的友情就像这样火红。 没有告别仪式，只是如青般离开。 “悄悄，是别离的笙箫” 迈入初中，一切都是陌生，交流变少了，浑浑噩噩的梦中，我又梦见了他们。 关了台灯，寂静与黑暗容我沉思。 初一就要结束的几天里，夏天悄无声息得把炎热带来，家人们又带回来了西瓜，复习之余，我又捧起了半个西瓜，这一回就我一人沉默。握着勺子，一口一口舀着慢慢品味。“嗯？”与瓜皮连着的青色果肉吸引了我。“啊！原来他们比中间的果肉更惹人迷！” 我舀了一勺，“咔嚓”，是多么清脆。 “但我不能放歌”，时光荏苒，十几年前的往事似乎又模模糊糊。 他们如流水划过，留下一道青色的痕迹。青，是青。 |
