【问题描述】:
我正在尝试登录到使用 https 的远程地址。 为此,我使用 volley 发送带有我的用户数据的 post-request。
这是我的相关代码(includes setting up a StringRequest -> fire StringRequest):
StringRequest myStringRequest = new StringRequest(Request.Method.POST, remoteurl, this, this) {
@Override
public Map<String, String> getHeaders() throws AuthFailureError {
Map<String, String> headers = new HashMap<>();
headers.put("Accept-Charset","utf-8");
headers.put("Connection","keep-alive");
headers.put("User-Agent","Mozilla/5.0 (X11; Ubuntu; Linux x86_64; rv:40.0) Gecko/20100101 Firefox/40.0");
headers.put("Content-Type","application/x-www-form-urlencoded");
return headers;
}
@Override
protected Map<String, String> getParams() throws AuthFailureError {
Map<String, String> params = new HashMap<>();
params.put("name","myname");
params.put("pw","mypw");
params.put("totp","");
params.put("app","76");
return params;
}
};
SingleTonVolley.getInstance().getRequestQueue(getActivity().getApplicationContext()).add(myStringRequest);
用于实例化 newRequestQueue 的 SingleTon 如下所示:
public class SingleTonVolley {
private static SingleTonVolley mInstance = new SingleTonVolley();
private RequestQueue mRequestQueue;
private SingleTonVolley() {
}
public static SingleTonVolley getInstance() {
return mInstance;
}
public synchronized RequestQueue getRequestQueue(Context context) {
if(mRequestQueue == null)
{
mRequestQueue = Volley.newRequestQueue(context);
}
return mRequestQueue;
}
}
但是,在运行我的代码时,我可以通过 WireShark 看到我的数据是使用 TLSv1.2 加密发送的:

关于SO的许多其他问题我可以看到每个人在创建newRequestQueue时都必须通过SSLSocketFactory。然而,虽然这对我来说听起来绝对合乎逻辑,但我想知道为什么我的程序默认会这样做,因为我没有添加任何 SSLSocketFactory。我想知道我是否拥有比过去在 SO 上提问时使用的其他用户更新版本的 volley。但是,在查看source-code of volley 时,我在使用https-url 时找不到任何检测,该SSLSocketFactory 会自动将SSLSocketFactory 分配给RequestQueue。
希望有人可以为我的问题带来一些启示。
加法
我能找到的只有SSLSocketFactory相关的东西在HurlStack.class中:
构造函数:
public HurlStack(UrlRewriter urlRewriter, SSLSocketFactory sslSocketFactory) {
mUrlRewriter = urlRewriter;
mSslSocketFactory = sslSocketFactory;
}
判断 SSLSocketFactory 是否通过:
// use caller-provided custom SslSocketFactory, if any, for HTTPS
if ("https".equals(url.getProtocol()) && mSslSocketFactory != null) {
((HttpsURLConnection)connection).setSSLSocketFactory(mSslSocketFactory);
}
所以"https".equals(url.getProtocol()) 在我的情况下将评估为真,但mSslSocketFactory != null 不会!
