Question

我尝试使用Reddit API（https://github.com/reddit/reddit - www.reddit.com/dev）。

这是我的HttpClientHelper：

public HttpClientHelper(String path)
{
    this.url = "www.reddit.com";
    this.path = path;

    if(httpClient == null)
    {
        httpClient = new DefaultHttpClient();
    }
}

public void addParamForGet(String key, String value)
{
    dataGet.add(new BasicNameValuePair(key, value));
}

public void addParamForPost(String key, String value)
{
    dataPost.add(new BasicNameValuePair(key, value));
}

public HttpResponse executePost()
{
    HttpResponse response = null;

    try {
        uri = URIUtils.createURI(METHOD, url, PORT, path,
                dataGet == null ? null : URLEncodedUtils.format(dataGet, "UTF-8"), null);

        HttpPost httpPost = new HttpPost(uri);
        httpPost.setHeader("Content-Type", "application/x-www-form-urlencoded");

        httpPost.setEntity(new UrlEncodedFormEntity(dataPost, HTTP.UTF_8));

        response = httpClient.execute(httpPost);
    } catch (ClientProtocolException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    } catch (IOException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    } catch (URISyntaxException e1) {
        // TODO Auto-generated catch block
        e1.printStackTrace();
    }

    return response;
}

public HttpResponse executeGet()
{
    try {
        uri = URIUtils.createURI(METHOD, url, PORT, path,
                dataGet == null ? null : URLEncodedUtils.format(dataGet, "UTF-8"), null);
    } catch (URISyntaxException e1) {
        // TODO Auto-generated catch block
        e1.printStackTrace();
    }

    HttpGet httpget = new HttpGet(uri);
    HttpResponse response = null;

    try {
        response = httpClient.execute(httpget);
    } catch (ClientProtocolException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    } catch (IOException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    }

    return response;
}

当我尝试登录Reddit时，它可以工作：

    HttpClientHelper client = new HttpClientHelper(Endpoints.User.login);

    client.addParamForPost("api_type", "json");
    client.addParamForPost("user", username);
    client.addParamForPost("passwd", password);
    client.addParamForPost("rem", String.valueOf(true));

    client.executePost();

结果：{"json":{"data":{"cookie":"30310021,2014-10-27T16:02:27,300937022ed465f695747a2aa7fd**********","need_https":false,"modhash":"9ch7btilr85ce7c2a427ef87bdb422132f738c3a1**********"},"errors":[]}}

以下是返回的Cookie（黯然失色）：

    List<Cookie> cookies = client.getHttpClient().getCookieStore().getCookies();
    for (int i = 0; i < cookies.size(); i++) {
        Log.d("", cookies.get(i).toString());
    }

在以下检索用户数据/api/me.json的请求中，它失败：

    HttpClientHelper client = new HttpClientHelper(Endpoints.User.me);
    client.executeGet();

结果：{}

但是，当我打印cookie时，结果是相同的（这是预期的，因为我使用相同的DefaultHttpClient实例）：

    List<Cookie> cookies = client.getHttpClient().getCookieStore().getCookies();
    for (int i = 0; i < cookies.size(); i++) {
        Log.d("", cookies.get(i).toString());
    }

我做错了什么？

感谢。

旧帖但......

您没有在检索用户数据时指出失败的性质。

我观察到的一件事是reddit_session cookie的域名为“reddit.com”，而另一个域名为“.reddit.com”。当您使用'reddit.com而不是'www.reddit.com'时，前者只会被发送回服务器，而后者将被发送到所有子域。也许这就是失败的原因。

如果您实际上使用“www.reddit.com”域名作为原始请求，我很困惑您已经收回了这些cookie。

HttpClient不发送cookie
