我正在尝试从android到后端Django服务器发出get请求。每次发出请求时都会抛出异常,并且服务器不显示它已被联系。我该怎么做呢?感谢。
这是我的尝试:
客户端android:
try{
URI website = new URI(URL);
//Request to server
HttpGet httpget = new HttpGet();
httpget.setURI(website);
HttpResponse response = Client.execute(httpget);
Log.d("EXECUTED",response.toString());
}catch (Exception ex){
textView.setText("Fail");
}
服务器端Django:
def app(request, id):
context = RequestContext(request)
fab_categories = Catagories.objects.all()
return HttpResponse("worked")
按要求这是logcat:

嗨那里:)我正在开发一个类似的应用程序,我按照本教程。
很抱歉只是在这里删除一个链接,但这是非常自我解释的,代码记录很清楚。
忽略标题,查看InboxActivity.java代码
