我想使用改造同时发送此Postdata和imagefile。
PostData 和点
public class PostData implements Serializable {
@Expose
private String text;
@Expose
private Point point;
}
public class Point implements Serializable {
@Expose
private double longitude;
@Expose
private double latitude;
}
PostApiService
public interface PostApiService {
@Multipart
@POST("posts/")
Call<ResponseBody> uploadFile (@Part MultipartBody.Part part, @Body PostData postData);
}
我从这些代码中获取图像uri,我将使用它。它用作returnUri。 你可以考虑这个。
代码:
view.findViewById(R.id.btn_post).setOnClickListener(new View.OnClickListener() {
@Override
public void PostImageAndData(View view) {
Bitmap bitmap = null;
try {
bitmap = getBitmapFromUri(returnUri); #this method is to make Bitmap from Uri
} catch (IOException e) {
e.printStackTrace();
}
File imageFile = null;
try {
imageFile = createFileFromBitmap(bitmap); #this method is to make File from Bitmap
} catch (IOException e) {
e.printStackTrace();
}
OkHttpClient client = new OkHttpClient();
OkHttpClient.Builder builder = new OkHttpClient.Builder();
client = builder.build();
Retrofit retrofit = new Retrofit.Builder()
.client(client)
.addConverterFactory(GsonConverterFactory.create())
.baseUrl(Constants.HTTP.BASE_URL)
.build();
PostApiService postApiService = retrofit.create(PostApiService.class);
RequestBody requestFile =
RequestBody.create(MediaType.parse("multipart/form-data"), imageFile);
MultipartBody.Part body =
MultipartBody.Part.createFormData("image", makeImageFileName(), requestFile); #this method(makeimageFileName()) is for custom filename
Point mpoint = new Point(13, 15);
PostData postData = new PostData("hello", mpoint);
Call<ResponseBody> call = postApiService.uploadFile(body, postData);
call.enqueue(new Callback<ResponseBody>() {
@Override
public void onResponse(Call<ResponseBody> call, Response<ResponseBody> response) {
Toast.makeText(getContext(), "success?", Toast.LENGTH_LONG).show();
}
@Override
public void onFailure(Call<ResponseBody> call, Throwable t) {
}
});
}
});
如果我在PostApiService上使用@Body PostData postData
,则错误为java.lang.IllegalArgumentException: @Body parameters cannot be used with form or multi-part encoding. (parameter #2)
如果我在PostApiService上使用@Part PostData postData
,则错误为java.lang.IllegalArgumentException: @Part annotation must supply a name or use MultipartBody.Part parameter type. (parameter #2)
那么,我该怎么办?
拜托,你能帮助我吗?
答案 0 :(得分:2)
昨天我遇到了同样的问题,我已经解决了。
它直接说不允许两种不同的格式。 java.lang.IllegalArgumentException:@Body参数不能与表单或多部分编码一起使用。 (参数#2)
您需要仅以部分的形式发送所有数据。
@Multipart
@POST("/api/Accounts/editaccount")
Call<User> editUser (@Part("Authorization") String authorization,@Part("file\"; filename=\"pp.png\" ") RequestBody file , @Part("FirstName") RequestBody fname, @Part("Id") RequestBody id);
像这样。
谢谢希望这对你有所帮助。
