java.lang.RuntimeException: Failed : HTTP error code : 400 : Bad Request

Question

I am having following piece of code:

URL url = new URL(baseUrl);
    HttpURLConnection conn = (HttpURLConnection) url.openConnection();
    conn.setDoOutput(true);
    conn.setRequestMethod("POST");
    conn.setRequestProperty("Accept", "application/json");
    conn.setRequestProperty("Content-Type", "application/json");
    conn.setRequestProperty("Authorisation", "Bearer "+socialMedia.getFacebookPage_Token());
    String payload = "{\"name\":\""+segment.getName()+"\","
            + "\"subtype\":\"CUSTOM\","
            + "\"description\":\"Bingage Custom Audience\","
            + "\"customer_file_source\":\"USER_PROVIDED_ONLY\"}";
    OutputStreamWriter writer = new OutputStreamWriter(conn.getOutputStream(), "UTF-8");
    writer.write(payload);
    writer.close();
    if (conn.getResponseCode() != 200) {
        throw new RuntimeException("Failed : HTTP error code : "
                + conn.getResponseCode()+"  :  " +conn.getResponseMessage());
    }

I have checked data is getting populated properly. But when I make request I get following exception:

java.lang.RuntimeException: Failed : HTTP error code : 400  :  Bad Request

If I post same data with Postman it works like charm. I would like to know what I am doing wrong over here ?

I have also tried payload like this:

JSONObject data = new JSONObject();
    data.put("name", segment.getName());
    data.put("subtype", "CUSTOM");
    data.put("description", "Bingage Custom Audience");
    data.put("customer_file_source", "USER_PROVIDED_ONLY");
    writer.write(data.toString());

thanks in Advance!

不知道这是否使您失败，但是您拼错了Authorization标头
