import org.apache.http.client.HttpClient;
HttpClient client = HttpClientBuilder.create().build();
HttpPost post = new HttpPost(URL);
MultipartEntity multipart = new MultipartEntity();
File file = new File(FOLDER_PATH + "/" + name);
multipart.addPart("file", new FileBody(file));
post.setEntity(multipart);
HttpResponse response = client.execute(post);

发布文件需要做什么？

Answer 1

如果您不想要额外的东西，那么您不应该使用MultipartEntity。相反，您应该使用FileEntity。

HttpClient client = HttpClientBuilder.create().build();
HttpPost post = new HttpPost(URL);
File file = new File(FOLDER_PATH + "/" + name);
FileEntity fileEntity = new FileEntity(file);
post.setEntity(fileEntity);
HttpResponse response = client.execute(post);
