以下是Java代码示例,可以使用Spring Boot框架实现:
```
@RestController
public class MediaUploadController {
// 设置上传临时素材的URL和access_token
private static final String UPLOAD_URL = "https://qyapi.weixin.qq.com/cgi-bin/media/upload?access_token=%s&type=%s";
private static final String ACCESS_TOKEN = "your_access_token";
/**
* 上传临时素材
*/
@PostMapping("/media/upload")
public String uploadMedia(@RequestParam("file") MultipartFile file, @RequestParam("type") String type) throws Exception {
// 创建上传临时素材的URL
String uploadUrl = String.format(UPLOAD_URL, ACCESS_TOKEN, type);
// 创建HttpClient对象
CloseableHttpClient httpClient = HttpClients.createDefault();
try {
// 创建HttpPost对象,发送POST请求上传临时素材
HttpPost httpPost = new HttpPost(uploadUrl);
HttpEntity entity = MultipartEntityBuilder.create().addBinaryBody("media", file.getInputStream(), ContentType.DEFAULT_BINARY, file.getOriginalFilename()).build();
httpPost.setEntity(entity);
// 执行HttpPost请求
CloseableHttpResponse response = httpClient.execute(httpPost);
try {
// 处理上传结果
String responseBody = EntityUtils.toString(response.getEntity(), Charset.forName("UTF-8"));
return responseBody;
} finally {
response.close();
}
} finally {
httpClient.close();
}
}
}
```
其中,需要替换`ACCESS_TOKEN`为自己企业微信应用的access_token。`MultipartFile`是Spring框架的文件上传对象,可以获取前端传来的临时素材文件。上传结果可以根据实际需求进行自定义处理。
