问题描述
我试图描述创建一个HTTP POST到谷歌的服务器获得的ClientLogin验证（的）。该人士$ C $ C的职位是不是一个真正的奥秘，我发现它。 （我敢肯定，我的职务作品，因为使用curl我得到验证）
I'm trying to create an HTTP POST to Google servers to obtain the ClientLogin Auth (as described here). The source code for the post is not a real mystery and I found it here. (I'm sure my post works because using CURL I obtain the Auth)
方法很简单，当我执行以下命令行我已经相应修改的值，但是，我发现了以下异常：
The method is very simple and I've modified the values accordingly, however, I'm getting the following exception when I execute the following line:
HttpResponse response = client.execute(post);

（无关日志略）。
(irrelevant log omitted).
试图code的各种组合后（在谷歌找到和这里），不同的URL过（有或没有HTTPS），常规的HTTP太多，等我决定尝试以下操作：
After trying various combinations of code (found on google and here), different URLs too (with or without HTTPS), regular HTTP too, etc. I've decided to try the following:
try {
InetAddress address = InetAddress.getByName("http://www.google.com");
} catch (UnknownHostException e) {
e.printStackTrace();
}
和我得到同样的错误：（修剪无关的部分太）
and I get the same error: (trimmed the irrelevant parts too)

现在我已经重新开始肯定Eclipse的电话，我甚至忘记了Wi-Fi并重新创建它。我使用的是谷歌任何的DNS或OpenDNS的手机上的一个静态IP地址（我已经换他们尝试）。因特网在电话作品，其他的应用程序。
Now I've sure restarted Eclipse, The Phone, I've even forgotten the Wi-Fi and re-created it. I'm using a STATIC IP address on the phone with either Google's DNS or OpenDNS (i've swapped them to try). Internet on the phone works, other applications work.
我做有
<uses-permission android:name="android.permission.INTERNET" />
我在正确的位置（内部应用），其实我也有android.permission.ACCESS_FINE_LOCATION但是，这并不能改变什么。清单
on my Manifest in the correct spot (inside Application), in fact I also have "android.permission.ACCESS_FINE_LOCATION" but that doesn't change anything.
这是一个新鲜的Nexus S（解锁）采用Android 2.3.4。
It's a fresh Nexus-S (unlocked) with Android 2.3.4.
这是有问题的方法：（见线的Htt presponse响应= client.execute（岗位）;）
This is the method in question: (see line HttpResponse response = client.execute(post);)
请注意，我已经去掉了实际价值，但放心正确的值是在原来的code
public void getAuthentification(View view) {
SharedPreferences prefs = PreferenceManager
.getDefaultSharedPreferences(this);
HttpClient client = new DefaultHttpClient();
HttpPost post = new HttpPost(
"https://www.google.com/accounts/ClientLogin");
try {
List<NameValuePair> nameValuePairs = new ArrayList<NameValuePair>(1);
nameValuePairs.add(new BasicNameValuePair("Email", prefs.getString(
"user", "undefined")));
nameValuePairs.add(new BasicNameValuePair("Passwd", prefs
.getString("password", "undefined")));
nameValuePairs.add(new BasicNameValuePair("accountType", "GOOGLE"));
nameValuePairs.add(new BasicNameValuePair("source",
"Google-cURL-Example"));
nameValuePairs.add(new BasicNameValuePair("service", "ac2dm"));
post.setEntity(new UrlEncodedFormEntity(nameValuePairs));
HttpResponse response = client.execute(post);
BufferedReader rd = new BufferedReader(new InputStreamReader(
response.getEntity().getContent()));
String line = "";
while ((line = rd.readLine()) != null) {
Log.e("HttpResponse", line);
if (line.startsWith("Auth=")) {
Editor edit = prefManager.edit();
edit.putString(AUTH, line.substring(5));
edit.commit();
String s = prefManager.getString(AUTH, "n/a");
Toast.makeText(this, s, Toast.LENGTH_LONG).show();
}
}
} catch (IOException e) {
e.printStackTrace();
}
}
我是什么失踪？
推荐答案
好吧，看完之后，并在相反的是我在其他的谷歌搜索结果读过了...
Ok, after reading this answer and in contrary to what I've read in other google results, the…
<uses-permission android:name="android.permission.INTERNET" />
...必须应用程序之外
我有：
<!-- General Permissions -->
<uses-permission android:name="android.permission.INTERNET" />
</manifest>
现在它的作品。
