我在android emulator上连接到localhost时遇到问题。我已创建rest节点服务器:

...
app.listen(80, () => console.log('Example app listening on port 80!'))

当我尝试使用NativeScript连接到它时:

this.http.get("10.0.2.2/api/categories")
        .map(function (result) { return result.json(); })
        .subscribe(function (result) {
        console.log(result);
    });

我得到:

System.err: java.net.MalformedURLException: no protocol: 10.0.2.2/api/categories
System.err:     at java.net.URL.<init>(URL.java:590)
System.err:     at java.net.URL.<init>(URL.java:487)

System.err:     at java.lang.Thread.run(Thread.java:764)

我错过什么了吗?

尝试以下操作:

this.http.get("http://10.0.2.2/api/categories")
        .map(function (result) { return result.json(); })
        .subscribe(function (result) {
        console.log(result);
    });
