Question

我在Android模拟器上连接到localhost时遇到问题。我创建了休息节点服务器：

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

当我尝试使用NativeScript连接它时：

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

我明白了：

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)
JS: ERROR Error: Uncaught (in promise): Response with status: 200  for URL: null

我错过了什么吗？

试试这个：

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

NativeScript，Android - 与localhost的连接失败
