Weibo-Entwicklung 1 Client-HTTP-Paket abrufen und veröffentlichen

In diesem Blog geht es darum, wie der Client das HTTP-Protokoll kapselt und wie der Client die Post- und Get-Methoden verwendet, die zu den wichtigsten Codes gehören

Das Folgende ist ein Auszug aus Huang Shijuns „Android and PHP Development“
