Java url.openConnection（）

Question

1) How can I send specific request headers whilst a url.openConnection()?

2) Also, how can I, in addition, turn the request to a POST and send post data as well?

3) What document would you recommend to learn further more about url.openConnection() and its possibilities?

Thank you.

Answer 1

1. connection.addRequestProperty(headerName, headerValue);

2. You should call connection.setRequestMethod("POST"); , then call connection.getOutputStream() and write to this stream content of POST request.

3. google: "java http post example" brings tons of documentation. Here is the first one: http://www.exampledepot.com/egs/java.net/post.html
