Question

我最近下载了Retrofit 1.6.1并尝试在简单示例上进行测试。我注意到它不能使用10.0.2.2地址通过模拟器工作。

这是我简单的Java代码：

RestAdapter restAdapter = new RestAdapter.Builder().setEndpoint("http://10.0.2.2/sisecurite").build();
IssueTicketInterface issueTickets = restAdapter.create(IssueTicketInterface.class);

issueTickets.syncIssueTickets(55, new Callback<IssueTicketsCollection>() {
    @Override
    public void success(IssueTicketsCollection issueTickets, Response response) {
        System.out.println("Response : " + response);
        // TODO
    }

    @Override
    public void failure(RetrofitError exception) {
        Toast.makeText(MainActivity.this, exception.getMessage(), Toast.LENGTH_LONG).show();
    }
});

Retrofit给出的错误是：

failed to connect to localhost/127.0.0.1 (port 80) after 15000ms: isConnected failed: ECONNREFUSED (Connection refused)

错误直接显示，它不会等待15秒，如错误消息中所示。此外，10.0.2.2似乎转换为127.0.0.1

以下是failure()方法的完整堆栈跟踪：

请注意，我可以通过模拟器的网络浏览器完全访问http://10.0.2.2/sisecurite，因此它似乎是特定于Retrofit的错误。

有人总是有同样的问题，或者我错过了什么？

Answer 1

我终于找到了这种行为的原因。

原来，我尝试访问重定向我的页面到登录表单。这就是为什么Retrofit抛出一个错误，说“无法连接到localhost / 127.0.0.1”。

无法使用http://10.0.2.2在模拟器上使用Retrofit
