问题描述

我有哪些选择在Android中使用OKhttp上传单个大容量文件（更具体地说，S3）的多部分？

What are my options for uploading a single large file (more specifically, to s3) in multipart in Android using OKhttp?

推荐答案

从 OkHttp食谱页面，这code上传的图片Imgur：

From the OkHttp Recipes page, this code uploads an image to Imgur:

private static final String IMGUR_CLIENT_ID = "...";
private static final MediaType MEDIA_TYPE_PNG = MediaType.parse("image/png");

private final OkHttpClient client = new OkHttpClient();

public void run() throws Exception {
  // Use the imgur image upload API as documented at https://api.imgur.com/endpoints/image
  RequestBody requestBody = new MultipartBuilder()
      .type(MultipartBuilder.FORM)
      .addPart(
          Headers.of("Content-Disposition", "form-data; name=\"title\""),
          RequestBody.create(null, "Square Logo"))
      .addPart(
          Headers.of("Content-Disposition", "form-data; name=\"image\""),
          RequestBody.create(MEDIA_TYPE_PNG, new File("website/static/logo-square.png")))
      .build();

  Request request = new Request.Builder()
      .header("Authorization", "Client-ID " + IMGUR_CLIENT_ID)
      .url("https://api.imgur.com/3/image")
      .post(requestBody)
      .build();

  Response response = client.newCall(request).execute();
  if (!response.isSuccessful()) throw new IOException("Unexpected code " + response);

  System.out.println(response.body().string());
}

您将需要适应这S3，但类，你需要应该是一样的。

You'll need to adapt this to S3, but the classes you need should be the same.
