Add multiple headers to java http request

Question

I would like to add multiple headers to a java HTTP request, I think this is possible using the headers() method in the httpRequest builder, but I can't seem to figure out how:

 HttpRequest request = HttpRequest.newBuilder()
            .POST()
            .headers(/*add mutple headers here*/)
            .uri(getUrl())
            .build();

Does this answer your question? Adding map of httpheaders to builder — Joe

You can add multiple headers by invoking header(String,String) multiple times...

HttpRequest request2 = HttpRequest.newBuilder()
  .header("key1", "value1")
  .header("key2", "value2")
  ... stuff ...
  .build();

.. or you may use the varargs headers(String...) methods

HttpRequest request = HttpRequest.newBuilder()
  .headers("key1", "value1", "key2", "value2")
  ... stuff ...
  .build();

The method headers allow you to pass a single key/value or a list of key/value https://docs.oracle.com/en/java/javase/11/docs/api/java.net.http/java/net/http/HttpRequest.Builder.html#headers(java.lang.String...).

 HttpRequest request = HttpRequest.newBuilder()
            .POST()
            .headers("key1", "value1", "key2", "value2", "key3", "value3")
            .uri(getUrl())
            .build();
