为了能够使用Java来对接WPS协作接口并实现消息发送功能,您需要创建三个核心包:`controller`、`service`以及`utils`。下面我会概述每个包的大致框架:
### Controller层
这个层次负责接收HTTP请求并将其转换成适当的服务层请求。
#### ExampleController.java
```java
package com.example.controller;
import org.springframework.web.bind.annotation.PostMapping;
import org.springframework.web.bind.annotation.RequestBody;
import org.springframework.web.bind.annotation.RestController;
import com.example.dto.MessageRequest;
import com.example.service.MessageService;
@RestController
public class MessageController {
private final MessageService messageService;
public MessageController(MessageService messageService) {
this.messageService = messageService;
}
@PostMapping("/send-message")
public String sendMessage(@RequestBody MessageRequest request) {
return messageService.sendMessage(request);
}
}
```
### Service层
这一层处理所有与发送消息相关的逻辑操作,包括构建请求体、进行必要的认证及调用实际API。
#### MessageService.java
```java
package com.example.service;
import com.example.dto.MessageRequest;
import com.example.utils.WPSCollaborationUtils;
public class MessageService {
public String sendMessage(MessageRequest request) {
WPSCollaborationUtils utils = new WPSCollaborationUtils();
// 构建请求头和请求体
String requestBody = buildRequestBody(request);
String headers = buildHeaders();
// 调用WPS API 发送消息
String response = utils.sendPostRequest("https://openapi.wps.cn/kopen/woa/v2/dev/app/messages?company_token=YOUR_COMPANY_TOKEN",
headers,
requestBody);
return response;
}
private String buildRequestBody(MessageRequest request) {
// 根据MessageRequest构造具体的请求体JSON
return "{\"to_users\": {\"company_id\":\""+request.getCompanyId()+"\",\"company_uids\":[\""+request.getUserIds()+"\"]}, \"msg_type\": "+request.getMsgType()+", \"app_key\": \"your_app_id\", \"content\": {\"type\": "+request.getMsgType()+", \"body\": \""+request.getMessageContent()+"\"}}";
}
private String buildHeaders() {
// 根据实际情况构造headers,例如签名等
return "Content-Type: application/json; Content-Md5: XXX; Date: YYYY-MM-DDTHH:MM:SSZ; X-Auth: ZZZ";
}
}
```
### Utils层
这个层次封装了所有的工具类方法,如生成签名、发起网络请求等。
#### WPSCollaborationUtils.java
```java
package com.example.utils;
import java.io.IOException;
import java.net.HttpURLConnection;
import java.net.URL;
public class WPSCollaborationUtils {
public String sendPostRequest(String url, String headers, String body) throws IOException {
URL obj = new URL(url);
HttpURLConnection con = (HttpURLConnection) obj.openConnection();
// 设置请求类型为POST
con.setRequestMethod("POST");
// 设置请求头部信息
con.setRequestProperty("Content-Type", "application/json");
con.setRequestProperty("Content-Md5", calculateMd5(body));
con.setRequestProperty("Date", getCurrentDate());
con.setRequestProperty("X-Auth", generateXAuth());
// 发起请求
con.setDoOutput(true);
con.getOutputStream().write(body.getBytes());
int responseCode = con.getResponseCode();
if(responseCode == HttpURLConnection.HTTP_OK) {
return "Message sent successfully.";
} else {
return "Failed to send message. Response Code: " + responseCode;
}
}
private String calculateMd5(String input) {
// 实现计算输入字符串的MD5值的方法
return "";
}
private String getCurrentDate() {
// 获取当前日期,格式化为RFC1123标准
return "";
}
private String generateXAuth() {
// 生成X-Auth所需的数据
return "";
}
}
```
请注意上述代码仅为示例用途,并未真正实现某些关键功能比如加密算法或日期格式化等功能,请按照实际需求补充完整。此外,在真实环境中还需要考虑错误处理机制以增强程序鲁棒性。
