map = new HashMap <>(); RequestBody fileBody = RequestBody.create(MediaType.parse("image/jpg"),file); map.put("file \"; filename = \""+ file.getName(),fileBody);`
@insomniac是的我刚刚发现了这一点,也可以使用`MultiPartBody.Part`
2> jimmy0251..：
有一种正确的方法可以上传名称为Retrofit 2的文件,没有任何黑客攻击:
定义API接口:
@Multipart
@POST("uploadAttachment")
Call uploadAttachment(@Part MultipartBody.Part filePart);
// You can add other parameters too
像这样上传文件:
File file = // initialize file here
MultipartBody.Part filePart = MultipartBody.Part.createFormData("file", file.getName(), RequestBody.create(MediaType.parse("image/*"), file));
Call call = api.uploadAttachment(filePart);
这仅演示了文件上传,您还可以使用@Part注释在同一方法中添加其他参数.
我们如何使用MultipartBody.Part发送多个文件？

我为我的注册用户使用了Retrofit 2.0,从注册帐户发送multipart/form文件图像和文本
在我的RegisterActivity中,使用AsyncTask
//AsyncTask
private class Register extends AsyncTask {
@Override
protected void onPreExecute() {..}
@Override
protected String doInBackground(String... params) {
new com.tequilasoft.mesasderegalos.dbo.Register().register(txtNombres, selectedImagePath, txtEmail, txtPassword);
responseMensaje = StaticValues.mensaje ;
mensajeCodigo = StaticValues.mensajeCodigo;
return String.valueOf(StaticValues.code);
}
@Override
protected void onPostExecute(String codeResult) {..}
在我的Register.java类中,使用Retrofit进行同步调用
import android.util.Log;
import com.tequilasoft.mesasderegalos.interfaces.RegisterService;
import com.tequilasoft.mesasderegalos.utils.StaticValues;
import com.tequilasoft.mesasderegalos.utils.Utilities;
import java.io.File;
import okhttp3.MediaType;
import okhttp3.MultipartBody;
import okhttp3.RequestBody;
import okhttp3.ResponseBody;
import retrofit2.Call;
import retrofit2.Response;
/**Created by sam on 2/09/16.*/
public class Register {
public void register(String nombres, String selectedImagePath, String email, String password){
try {
// create upload service client
RegisterService service = ServiceGenerator.createUser(RegisterService.class);
// add another part within the multipart request
RequestBody requestEmail =
RequestBody.create(
MediaType.parse("multipart/form-data"), email);
// add another part within the multipart request
RequestBody requestPassword =
RequestBody.create(
MediaType.parse("multipart/form-data"), password);
// add another part within the multipart request
RequestBody requestNombres =
RequestBody.create(
MediaType.parse("multipart/form-data"), nombres);
MultipartBody.Part imagenPerfil = null;
if(selectedImagePath!=null){
File file = new File(selectedImagePath);
Log.i("Register","Nombre del archivo "+file.getName());
// create RequestBody instance from file
RequestBody requestFile =
RequestBody.create(MediaType.parse("multipart/form-data"), file);
// MultipartBody.Part is used to send also the actual file name
imagenPerfil = MultipartBody.Part.createFormData("imagenPerfil", file.getName(), requestFile);
}
// finally, execute the request
Call call = service.registerUser(imagenPerfil, requestEmail,requestPassword,requestNombres);
Response bodyResponse = call.execute();
StaticValues.code = bodyResponse.code();
StaticValues.mensaje = bodyResponse.message();
ResponseBody errorBody = bodyResponse.errorBody();
StaticValues.mensajeCodigo = errorBody==null
?null
:Utilities.mensajeCodigoDeLaRespuestaJSON(bodyResponse.errorBody().byteStream());
Log.i("Register","Code "+StaticValues.code);
Log.i("Register","mensaje "+StaticValues.mensaje);
Log.i("Register","mensajeCodigo "+StaticValues.mensaje);
}
catch (Exception e){
e.printStackTrace();
}
}
}
在RegisterService的界面中
public interface RegisterService {
@Multipart
@POST(StaticValues.REGISTER)
Call registerUser(@Part MultipartBody.Part image,
@Part("email") RequestBody email,
@Part("password") RequestBody password,
@Part("nombre") RequestBody nombre
);
}
对于Utilities解析的InputStream响应
public class Utilities {
public static String mensajeCodigoDeLaRespuestaJSON(InputStream inputStream){
String mensajeCodigo = null;
try {
BufferedReader reader = new BufferedReader(
new InputStreamReader(
inputStream, "iso-8859-1"), 8);
StringBuilder sb = new StringBuilder();
String line;
while ((line = reader.readLine()) != null) {
sb.append(line).append("\n");
}
inputStream.close();
mensajeCodigo = sb.toString();
} catch (Exception e) {
Log.e("Buffer Error", "Error converting result " + e.toString());
}
return mensajeCodigo;
}
}

更新Retrofit2.0中图像文件上传的代码
public interface ApiInterface {
@Multipart
@POST("user/signup")
Call updateProfilePhotoProcess(@Part("email") RequestBody email, @Part("password") RequestBody password, @Part("profile_pic\"; filename=\"pp.png\" ") RequestBody file);
}
更改MediaType.parse("image/*")到MediaType.parse("image/jpeg")
RequestBody reqFile = RequestBody.create(MediaType.parse("image/jpeg"), file);
RequestBody email = RequestBody.create(MediaType.parse("text/plain"), "upload_test4@gmail.com");
RequestBody password = RequestBody.create(MediaType.parse("text/plain"), "123456789");
Call call = apiService.updateProfilePhotoProcess(email,password,reqFile);
call.enqueue(new Callback() {
@Override
public void onResponse(Call call, Response response) {
String TAG = response.body().toString();
UserModelResponse userModelResponse = response.body();
UserModel userModel = userModelResponse.getUserModel();
Log.d("MainActivity","user image = "+userModel.getProfilePic());
}
@Override
public void onFailure(Call call, Throwable t) {
Toast.makeText(MainActivity.this,""+TAG,Toast.LENGTH_LONG).show();
}
});
5> Anjana Sharm..：
添加@insomniac给出的答案.您可以创建一个Map用于放置RequestBody包含图像的参数.
接口代码
public interface ApiInterface {
@Multipart
@POST("/api/Accounts/editaccount")
Call editUser (@Header("Authorization") String authorization, @PartMap Map map);
}
Java类的代码
File file = new File(imageUri.getPath());
RequestBody fbody = RequestBody.create(MediaType.parse("image/*"), file);
RequestBody name = RequestBody.create(MediaType.parse("text/plain"), firstNameField.getText().toString());
RequestBody id = RequestBody.create(MediaType.parse("text/plain"), AZUtils.getUserId(this));
Map map = new HashMap<>();
map.put("file\"; filename=\"pp.png\" ", fbody);
map.put("FirstName", name);
map.put("Id", id);
Call call = client.editUser(AZUtils.getToken(this), map);
call.enqueue(new Callback() {
@Override
public void onResponse(retrofit.Response response, Retrofit retrofit)
{
AZUtils.printObject(response.body());
}
@Override
public void onFailure(Throwable t) {
t.printStackTrace();
}
});

因此，这是完成任务的非常简单的方法。您需要按照以下步骤操作：-
1.第一步
public interface APIService {
@Multipart
@POST("upload")
Call upload(
@Part("item") RequestBody description,
@Part("imageNumber") RequestBody description,
@Part MultipartBody.Part imageFile
);
}
您需要按进行整个通话@Multipart request。item并且image number是被包裹在刚刚绳体RequestBody。我们使用的MultipartBody.Part class，使我们除了发送带有请求的二进制文件数据外，还可以发送实际的文件名
2.第二步
File file = (File) params[0];
RequestBody requestFile = RequestBody.create(MediaType.parse("multipart/form-data"), file);
MultipartBody.Part body =MultipartBody.Part.createFormData("Image", file.getName(), requestBody);
RequestBody ItemId = RequestBody.create(okhttp3.MultipartBody.FORM, "22");
RequestBody ImageNumber = RequestBody.create(okhttp3.MultipartBody.FORM,"1");
final Call request = apiService.uploadItemImage(body, ItemId,ImageNumber);
现在您拥有了image path，您需要转换为file.Now转换file为RequestBodyusing方法RequestBody.create(MediaType.parse("multipart/form-data"), file)。现在，您需要将转换RequestBody requestFile为MultipartBody.Partusing方法MultipartBody.Part.createFormData("Image", file.getName(), requestBody);。
ImageNumber并且ItemId是我需要发送到服务器的另一个数据，因此我也将两者都放入了RequestBody。
