Question

我正在尝试通过HttpURL连接创建一个FlickR请求，我在con.getInputStream（）上得到一个java.net.protocolException

        Thread thread = new Thread(new Runnable(){
            @Override
            public void run() {
                try {
                    URL turl = new URL(url);                        
                    HttpsURLConnection con = (HttpsURLConnection)turl.openConnection();                     
                    InputStream inputStream = con.getInputStream();
                    xml = getStringFromInputStream(inputStream);
                    uihandler.post(obj.updateRunnable);
                } catch (Exception e) {
                    e.printStackTrace();
                }
            }
        });

网址是

static final String URL =“https://api.flickr.com/services/rest/?method=flickr.interestingness.getList&api_key=XXXXXXXXXX”;

你得到的是html而不是xml，这是你获得例外的原因检查你的网址。

Answer 2

服务器无法返回正确形成的HTTP响应。相反，它只是直接返回HTML，没有HTTP标头。在客户端你无能为力。抱怨服务器的人。如果那是你，请修理它。

BTW无法与HTTPS或SSL完美配合，

在android中使用HttpsURLConnection的java.net.protocolException
