改造2:使用json对象发送文件 [英] Retrofit 2 : send files with json object
本文介绍了改造2:使用json对象发送文件的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着小编来一起学习吧!
问题描述
我正在请求主体中发送对象,诸如此类:
I'm sending object in request body, something like that :
{
"title":"test",
"description":"test",
"images":[]
}
@POST("create-data")
Call<JsonObject> publishData(@Body MyObject object);
,并且没有图像也可以正常工作.从文档中,我可以找到如何使用MultipartBody.Part
将文件上传到服务器,我的问题是:
and it's work fine without the images. From the docs I can find how to upload file to server using MultipartBody.Part
, my questions is :
- 如何同时上传多张图片?
- 是否可以将图像发送到对象内部,还是需要单独发送?如何发送?
非常感谢.
推荐答案
服务器刚刚请求成功
我引用了这篇文章:
request success just now with server
I reference the article:
https://futurestud.io/blog/retrofit-2-如何将文件上传到服务器
@Multipart
@POST("uploadHeadPic")
Call<UploadHeadPicResponseModel> uploadHeadPic(@Part MultipartBody.Part file, @Part("json") RequestBody json);
public void doUploadHeadPic(@NonNull String filePath) {
if (!MNetworkUtil.isNetworkAvailable()) {
MToastUtil.show("网络不能连接");
return;
}
File file = new File(filePath);
String json = new Gson().toJson(new UploadHeadPicRequestModel());
if (!file.exists()) {
MToastUtil.show("文件不存在");
return;
}
progressDialog.show();
avatarSimpleDraweeView.setEnabled(false);
MApiManager.getService().uploadHeadPic(
MultipartBody.Part.createFormData("file", file.getName(), RequestBody.create(MediaType.parse("multipart/form-data"), file)),
RequestBody.create(MediaType.parse("multipart/form-data"), json))
.enqueue(new OnRetrofitCallbackListener<UploadHeadPicResponseModel>(mActivity) {
@Override
public void onSuccess(UploadHeadPicResponseModel responseModel) {
progressDialog.dismiss();
avatarSimpleDraweeView.setEnabled(true);
if (responseModel != null) {
String serverAvatarUrl = responseModel.data.headPicPath;
if (!TextUtils.isEmpty(serverAvatarUrl)) {
UserModel userModel = MUserManager.getInstance().getUser();
if (userModel != null) {
userModel.setAvatarUrl(serverAvatarUrl);
MUserManager.getInstance().updateOrInsertUserInfo(userModel);
MToastUtil.show("上传头像成功");
}
}
}
}
@Override
public void onFailure(int status, String failureMsg) {
progressDialog.dismiss();
avatarSimpleDraweeView.setEnabled(true);
MToastUtil.show((TextUtils.isEmpty(failureMsg) ? "上传失败" : failureMsg) + " : " + status);
}
});
}
更新多个文件
这可能会有所帮助,我没有尝试
update for multi files
may be this could help , I did not try
@Multipart
@POST("uploadHeadPic")
Call<UploadHeadPicResponseModel> uploadHeadPic(@Part MultipartBody.Part file0, @Part MultipartBody.Part file1, @Part("json") RequestBody json);
public void doUploadHeadPic(@NonNull String filePath) {
MApiManager.getService().uploadHeadPic(
MultipartBody.Part.createFormData("file0", file0.getName(), RequestBody.create(MediaType.parse("multipart/form-data"), file0)),
MultipartBody.Part.createFormData("file1", file1.getName(), RequestBody.create(MediaType.parse("multipart/form-data"), file1)),
RequestBody.create(MediaType.parse("multipart/form-data"), json))
.enqueue(new OnRetrofitCallbackListener<UploadHeadPicResponseModel>(mActivity) {
@Override
public void onSuccess(UploadHeadPicResponseModel responseModel) {
}
@Override
public void onFailure(int status, String failureMsg) {
}
});
}
