1.文件上传

*/

// 服务器的域名

// 设置为POST情

2.返回结果实体类
import java.io.Serializable;
public class AccessTokenWX implements Serializable {

private String errCode;
private String errMsg;

return errMsg;
}
public void setErrMsg(String errMsg) {
this.errMsg = errMsg;
}
@Override
public String toString() {
return "{" +
"errCode='" + errCode + '\'' +
", errMsg='" + errMsg + '\'' +
'}';
}
}
3.任务处理

private String url;
private MultipartFile file;
private String content;
public CheckTask(){}
public CheckTask(String url, MultipartFile file, String content) {
this.url = url;
this.file = file;
this.content = content;
}
@Override
protected AccessTokenWX compute() {
AccessTokenWX result = new AccessTokenWX();
try {
if (null == content){
String json = UploadAction.uploadFile(url, file);

}
} catch (Exception e) {
result.setErrCode("500");
