如何使用改造同时发送图像和文本 [英] How to send image and text at the same time using retrofit
问题描述
我想使用改造同时发送此 Postdata 和图像文件.
I want send this Postdata and imagefile at the same time using retrofit.
PostData 和 Point
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);
}
我从这些代码中得到图像 uri,我将使用它.它用作 returnUri.你可以考虑这个.
I get image uri out of these codes, and i will use it. It used as returnUri. You may consider this.
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
,错误是 java.lang.IllegalArgumentException:@Body 参数不能与表单或多部分编码一起使用.(参数#2)
If i use @Body PostData postData
on PostApiService, Error is 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
,错误是 java.lang.IllegalArgumentException:@Part 注释必须提供一个名称或使用 MultipartBody.Part 参数类型.(参数#2)
and If i use @Part PostData postData
on PostApiService, Error is java.lang.IllegalArgumentException: @Part annotation must supply a name or use MultipartBody.Part parameter type. (parameter #2)
那我该怎么办?
请帮帮我好吗?
推荐答案
昨天我遇到了同样的问题,我已经解决了.
Yesterday i had same problem and i have solved it.
直接说两种不同的格式是不允许的.java.lang.IllegalArgumentException:@Body 参数不能与表单或多部分编码一起使用.(参数#2)
It directly said two different format is not allowed. java.lang.IllegalArgumentException: @Body parameters cannot be used with form or multi-part encoding. (parameter #2)
您只需要以部分的形式发送所有数据.
You need to send all data in form of Part only.
@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);
类似的东西.
谢谢,希望对您有所帮助.
