try {
System.out.println("FirebaseInstanceId.getInstance().getToken()" + token);
//String data = URLEncoder.encode("?api-fcm=register", "UTF-8");
String data = URLEncoder.encode("regid", "UTF-8")
+ "=" + URLEncoder.encode(FirebaseInstanceId.getInstance().getToken(), "UTF-8");
if ( ContextCompat.checkSelfPermission( this, Manifest.permission.READ_PHONE_STATE ) == PackageManager.PERMISSION_GRANTED ) {
data += "&" + URLEncoder.encode("serial", "UTF-8") + "=" + URLEncoder.encode( Build.SERIAL, "UTF-8");
}
data += "&" + URLEncoder.encode("device_name", "UTF-8")
+ "=" + URLEncoder.encode(getDeviceName(), "UTF-8");
data += "&" + URLEncoder.encode("os_version", "UTF-8")
+ "=" + URLEncoder.encode(getAndroidVersion(), "UTF-8");
String text = "";
BufferedReader reader = null;
try {
URL url = new URL("http://somelink");
URLConnection conn = url.openConnection();
conn.setDoOutput(true);
OutputStreamWriter wr = new OutputStreamWriter(conn.getOutputStream());
wr.write(data);
wr.flush();
reader = new BufferedReader(new InputStreamReader(conn.getInputStream()));
StringBuilder sb = new StringBuilder();
String line = null;
while ((line = reader.readLine()) != null) {
sb.append(line + "\n");
}
text = sb.toString();
} catch (Exception ex) {
推荐答案
执行以下代码:
HttpUrlConnection myURLConnection = (HttpUrlConnection)conn;
myURLConnection.setRequestProperty("Content-Type", "application/x-www-form-urlencoded");
myURLConnection.setRequestProperty("Content-Length", "" + postData.getBytes().length);
myURLConnection.setRequestProperty("Content-Language", "en-US");
在行后添加此内容:
URLConnection conn = url.openConnection();
这里的"Content-Type","Content-Length","Content-Language"都是标题.
and here "Content-Type", "Content-Length", "Content-Language" are headers here.
谢谢,让我知道是否需要更多.
Thanks and let me know if need more.
