java.lang.RuntimeException：失败：HTTP 错误代码：400：错误请求

Question

我有以下代码：

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());
    }

我已检查数据是否正确填充。但是当我提出请求时，出现以下异常：

java.lang.RuntimeException: Failed : HTTP error code : 400  :  Bad Request
at com.wallet.service.impl.SocialMediaServiceImpl.createCustomAudience(SocialMediaServiceImpl.java:218)

如果我 post 与 Postman 相同的数据，它就像魅力一样。我想知道我在这里做错了什么？

我也试过这样的有效载荷：

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());

提前致谢！
