这主要是因为文件上传的时候没有设置类型,比如
enctype="multipart/form-data"
Retrofit 2.0 后TypedFile类好像被取消了(反正就是找不到)。
解决方案:
其中一定要添加上filename这个
public interface CheckIn { @Multipart @POST("/check/checkin.action") Call<ResponseCode> checkIn(@Part("image\"; filename=\"文件名.jpg") RequestBody file); }创建RequestBody对象作为参数上传
RequestBody imgFile = RequestBody.create(MediaType.parse("image/*"), imgFile);
以上方法解决了文件正常上传的问题,但是文件名却只能是常量,固定死了,并不是理想的结果,那么接下来就是解决这个问题。
首先是不需要在interface上定义文件名,而是通过Map来上传所有参数。
参数定义如下:
try { Staff staff = (Staff) SharedPreferencesUtils.getObject(context,LoginActivity.LOGIN_USER); RequestBody staffPhone = RequestBody.create(MediaType.parse("text/plain"), staff.getPhone()); RequestBody time = RequestBody.create(MediaType.parse("text/plain"), "时间"); RequestBody address = RequestBody.create(MediaType.parse("text/plain"), "地点"); RequestBody type = RequestBody.create(MediaType.parse("text/plain"), "类型"); Map<String, RequestBody> map = new HashMap<>(); map.put("staffPhone",staffPhone); map.put("checkTime",time); map.put("checkAddress",address); map.put("checkType",type); if (imgFile != null) { RequestBody fileBody = RequestBody.create(MediaType.parse("image/png"), imgFile); map.put("image\"; filename=\""+imgFile.getName()+"", fileBody); } HttpService.checkIn(map); } catch (IOException e) { e.printStackTrace(); }interface如下:
public interface CheckIn{ @Multipart @POST("/check/checkin.action") Call<ResponseCode> checkIn(@PartMap Map<String, RequestBody> params); }
OK,搞定。
