我的要求与this question非常相似。
基本上,我将在我的Android应用程序中有一个登录活动,当用户输入数据并点击登录时,我必须点击我的网站,验证用户,获得结果并根据登录成功进一步引导用户或不
以下是我的问题。

您可以使用HttpClient
<:p>发布到URI
URI uri = URI.create("http://whatever.com/thingie");
HttpPost post = new HttpPost(uri);
StringEntity ent = new StringEntity("Here is my data!");
post.setEntity(ent);
HttpClient httpClient = new DefaultHttpClient();
HttpResponse response = httpClient.execute(request);
您需要查看的所有内容都在包org.apache.http.client
中。互联网上有很多其他的例子可以帮助你。

HttpClient非常适合这一点。 DroidFu是一个开源库,它提供了一个如何有效使用HttpClient的绝佳示例。你可以找到它here。
答案 2 :(得分:1)
让我展示一下使用示例代码(我之前的答案中的示例代码来自SO):
public CookieStore sendPostData(String url, String user, String pass) {
// Setup a HTTP client, HttpPost (that contains data you wanna send) and
// a HttpResponse that gonna catch a response.
DefaultHttpClient postClient = new DefaultHttpClient();
HttpPost httpPost = new HttpPost(url);
HttpResponse response;
try {
// Make a List. Increase the size as you wish.
List<NameValuePair> nameValuePairs = new ArrayList<NameValuePair>(2);
// Add your form name and a text that belongs to the actual form.
nameValuePairs.add(new BasicNameValuePair("username_form", user));
nameValuePairs.add(new BasicNameValuePair("password_form", pass));
// Set the entity of your HttpPost.
httpPost.setEntity(new UrlEncodedFormEntity(nameValuePairs));
// Execute your request against the given url and catch the response.
response = postClient.execute(httpPost);
// Status code 200 == successfully posted data.
if(response.getStatusLine().getStatusCode() == 200) {
// Green light. Catch your cookies from your HTTP response.
CookieStore cookies = postClient.getCookieStore();
return cookies;
}
} catch (Exception e) {
}
}
现在,您需要在对服务器发出请求之前设置Cookie(或检查/验证它们)。
示例代码:
CookieStore cookieStore = sendPostData("www.mypage.com/login", "Username",
"Password");
// Note, you may get more than one cookie, therefore this list.
List<Cookie> cookie = cookieStore.getCookies();
// Grab the name of your cookie.
String cookieOne = cookie.get(0).getName();
您真正需要做的是使用信息工具检查HTTP response
,例如Wireshark。通过计算机浏览器登录并在您的响应中检查/查找正确的值(使用String value = cookie.get(0).getValue();
的Java / Android代码获取值)。
这是您为自己的域设置Cookie的方式:
// Grab the domain of your cookie.
String cookieOneDomain = cookie.get(0).getDomain();
CookieSyncManager.createInstance(this);
CookieManager cookieManager = CookieManager.getInstance();
cookieManager.setAcceptCookie(true);
cookieManager.setCookie(cookieOneDomain, cookieOne);
