Send Byte array as file in using http client in java
提问by Hossein Nasr
We have byte array of file and we want to upload it as file.
FileBodyonly gets Fileas parameter but we have a array of bytes.
我们有文件的字节数组，我们想将它作为文件上传。
FileBody仅File作为参数获取，但我们有一个字节数组。
One solution is to save byte array into file and then send it but it is not appropriate for me.
一种解决方案是将字节数组保存到文件中然后发送，但它不适合我。
byte b[]= new byte[1000];
//fill b
MultipartEntity form = new MultipartEntity();
form.addPart("file", new FileBody(/* b? */));
thanks.
谢谢。

You can do something like
你可以做类似的事情
HttpClient client=null;
byte b[]= new byte[1000];
MultipartEntity form = new MultipartEntity();
ContentBody cd = new InputStreamBody(new ByteArrayInputStream(b), "my-file.txt");
form.addPart("file", cd);
HttpEntityEnclosingRequestBase post = new HttpPost("");//If a PUT request then `new HttpPut("");`
post.setEntity(form);
client.execute(post);

You can use ByteArrayBodyinstead InputStreamBody or FileBody.
您可以使用ByteArrayBody代替 InputStreamBody 或 FileBody。
HttpClient client=null;
byte b[]= new byte[1000];
MultipartEntity form = new MultipartEntity();
ContentBody cd = new ByteArrayBody(b, "my-file.txt");
form.addPart("file", cd);
HttpEntityEnclosingRequestBase post = new HttpPost("");
post.setEntity(form);
client.execute(post);
