问题 I am using HttpURLConnection to pass json query to php server and it doesn't work the way I want. The connection is fine, I got proper error respond from server side and I am sure the json string is properly handled. eg: {"id":55,"date":"2011111","text":"","latitude":13.0,"longitude":123.0,"share":0,"image":"Image","sound":"sound"} However, the php server cannot load the variable $_POST with the string that I have sent.

问题 I have to emulate browser behaviour from Java code. I have to set two cookies on a request before posting it to the server. I do this: HttpURLConnection conn = ... ... conn.addRequestProperty("Cookie", "IDS_SSO_ID=" + "onething"); conn.addRequestProperty("Cookie", "JSESSIONID=" + "otherthing")); ... conn.close(); On the server logs I see that the 'IDS_SSO_ID' cookie is retrieved as "onething, JSESSIONID", which causes an error.

问题 I want to send JSON string to the server every 60 seconds with HttpURLConnection API. I am running the app on my smartphone device, which is connected to the laptop via USB cable.
