android使用retrofit上传文件中包含中文的处理方法

说明:

使用Retrofit上传文件，如果选择的上传文件名file.getName()包含中文会出现错误，需要进行编码
 

.addFormDataPart("file",URLEncoder.encode(file.getName(), "utf-8"), fileBody)

可能出问题的代码:

   public static Flowable upload(int userId, String session, File file, UpLoadProgressInterceptor.UploadListener uploadListener) {
        RequestBody fileBody = RequestBody.create(MediaType.parse("text/plain; charset=utf-8"), file);
        RequestBody requestBody = new MultipartBody.Builder()
                .setType(MultipartBody.FORM)
                .addPart(Headers.of("Content-Disposition", "form-data;"), fileBody)
                .addFormDataPart("userId", userId + "")
                .addFormDataPart("file", file.getName(), fileBody)
                .addFormDataPart("session", session)
                .build();

        return RetrofitSingleton.getInstance()
                .getUploadApiService(ApiInterface.class, uploadListener)
                .upload(requestBody)
                .compose(new DefaultTransformer());
    }

修改:

 
    public static Flowable upload(int userId, String session, File file, UpLoadProgressInterceptor.UploadListener uploadListener) {

        RequestBody fileBody = RequestBody.create(MediaType.parse("text/plain; charset=utf-8"), file);
        RequestBody requestBody = new MultipartBody.Builder()
                .setType(MultipartBody.FORM)
                .addPart(Headers.of("Content-Disposition", "form-data;"), fileBody)
                .addFormDataPart("userId", userId + "")
                .addFormDataPart("file",URLEncoder.encode(file.getName(), "utf-8"), fileBody)
                .addFormDataPart("session", session) //------------------文件名称需要编码，其他字段不需要
                .build();

        return RetrofitSingleton.getInstance()
                .getUploadApiService(ApiInterface.class, uploadListener)
                .upload(requestBody)
                .compose(new DefaultTransformer());
    }
