How to upload InputStream to HttpURLConnection
问题
I have created a HttpURLConnection using which i need to upload a file to a specific URL. Below is my code
String uURL = "http:some_domain/add";URL url = new URL(uURL);HttpURLConnection connection = (HttpURLConnection) url.openConnection();connection.setDoOutput(true);connection.setRequestProperty("Content-Type", "text/plain");connection.setRequestMethod("PUT");OutputStreamWriter out = new OutputStreamWriter(connection.getOutputStream());InputStream iStream = getContent("ABC", "test.json");
Now, i have retrieved my content in iStream and want to upload it using OutputStreamWriter. How can i upload the content?

如果您的内容是文本文件，您可以使用OutputStreamWriter。（看起来您的文件是一个json）
try (OutputStream os = con.getOutputStream();OutputStreamWriter osw = new OutputStreamWriter(os, "UTF-8")) {String data = "{\"name\": \"John\", \"age\": 30}";osw.write(data);osw.flush();} catch (UnsupportedEncodingException e) {throw new RuntimeException(e);} catch (IOException e) {throw a RuntimeException(e);}
如果您的内容是二进制文件，您可以使用DataOutputStream
try (OutputStream os = con.getOutputStream();DataOutputStream dos = new DataOutputStream(os)) {byte[] data = {0x01, 0x02, 0x03, 0x04, 0x05};dos.write(data);dos.flush();} catch (IOException e) {throw new RuntimeException(e);}

If your content is text file you can use OutputStreamWriter. (It's look like your file is a json)
try (OutputStream os = con.getOutputStream();OutputStreamWriter osw = new OutputStreamWriter(os, "UTF-8")) {String data = "{\"name\": \"John\", \"age\": 30}";osw.write(data);osw.flush();} catch (UnsupportedEncodingException e) {throw new RuntimeException(e);} catch (IOException e) {throw new RuntimeException(e);}
If your content is binary file you can use DataOutputStream
try (OutputStream os = con.getOutputStream();DataOutputStream dos = new DataOutputStream(os)) {byte[] data = {0x01, 0x02, 0x03, 0x04, 0x05};dos.write(data);dos.flush();} catch (IOException e) {throw new RuntimeException(e);}
