@POST("file/upload")
Observable getImage(@Query("uid") int uid, @Part MultipartBody.Part file);
}
(3)bean
public class ImageBean {
/**
* msg : 文件上传成功
* code : 0
*/
private String msg;
private String code;
public String getMsg() {
return msg;
}
public void setMsg(String msg) {

public static final String URL_TOPHAEDS="http://www.zhaoapi.cn/";
