如何使用AsyncHttpClient Android上传多个文件 [英] How to upload multiple files with AsyncHttpClient Android

问题描述

我知道我可以从AsyncHttpClient上传单个文件

I know I can upload single file from AsyncHttpClient

http://loopj.com/android-async-http/

File myFile = new File("/path/to/file.png");
RequestParams params = new RequestParams();
try {
    params.put("profile_picture", myFile);
} catch(FileNotFoundException e) {}

但是我必须通过多篇文章将多个文件上传到服务器. 我该怎么办?

But I have to upload multiple files to the server with multipart post. How can I do that?

推荐答案

您可以传递文件数组作为files键的值. 为此，请遵循以下代码:

You can pass a file array as value for the files key. In order to do that, follow the code below:

File[] myFiles = { new File("pic.jpg"), new File("pic1.jpg") }; 
RequestParams params = new RequestParams();
try {
    params.put("profile_picture[]", myFiles);
} catch(FileNotFoundException e) {

}

另外，如果需要动态数组，可以使用ArrayList 并使用.toArray()

Aditionally, if you want a dynamic array, you can use an ArrayList and convert to File[] type with the method .toArray()

ArrayList<File> fileArrayList = new ArrayList<>();

//...add File objects to fileArrayList

File[] files = new File[fileArrayList.size()];  
fileArrayList.toArray(files);
