我正在尝试使用以下JAVA代码使用REST API将一些数据发送到Firebase实时数据库.
public void doWork() {
consumer.subscribe(Collections.singletonList(this.topic));
ConsumerRecords records = consumer.poll(1000);
for (ConsumerRecord record : records) {
System.out.println(“Sending data: ” + record.value() );
// https://testiosproject-6054a.firebaseio.com/users.json
// 1. URL
URL url;
try {
url = new URL(“https://testiosproject-1234a.firebaseio.com/users.json”);
// 2. Open connection
HttpURLConnection conn = (HttpURLConnection) url.openConnection();
conn.setDoOutput(true);
// 3. Specify POST method
conn.setRequestMethod(“POST”);
conn.setRequestProperty(“Content-Type”, “application/json”);
conn.setRequestProperty(“Accept”, “application/json”);
conn.connect();
// Write data
OutputStream os = conn.getOutputStream();
OutputStreamWriter osw = new OutputStreamWriter(os, “UTF-8”);
osw.write(record.value());
osw.flush();
osw.close();
} catch (MalformedURLException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
以下是试图发送的数据：
Sending data: {“UserID”:”101″,”UserAddress”:”XYZ”,”UserAccount”:”987″,”UserName”:”Stella”}
但是,我没有在Firebase实时数据库控制台上收到此数据.我不确定这个问题的原因是什么？
我试过Postman客户端并尝试了相同的URL和数据,它工作正常.
有人可以指导我解决这个问题吗？
