我需要使用用户名和密码对 oauth 提供商进行授权。在 iOS 端,有一个运行良好的开源库“AFOAuth2Client”。有图书馆吗?或者我将如何使用 Java 代码?我试过这个:
this.http_client = new DefaultHttpClient();
oauth_consumer = new CommonsHttpOAuthConsumer(Constants.clientId, Constants.clientSecret);
HttpPost httppost = new HttpPost("https://test.com/v1/oauth/token?api_key=gnxkfzquuahaswuxjrkv9ct3");
ArrayList<BasicNameValuePair> name_value_pairs = new ArrayList<BasicNameValuePair>(2);
HashMap<String, String> params = new HashMap<String, String>();
params.put("grant_type", "password");
params.put("username", "xxxxx@everything.com");
params.put("password", "xxxxx");
Iterator iter = params.entrySet().iterator();
while (iter.hasNext())
{
Map.Entry pairs = (Map.Entry) iter.next();
name_value_pairs.add(new BasicNameValuePair((String) pairs.getKey(), (String) pairs.getValue()));
}
try
{
// Put our parameters in our Post
httppost.setEntity(new UrlEncodedFormEntity(name_value_pairs));
// sign our request
this.oauth_consumer.sign(httppost);
// Yoiks, and away!
HttpResponse response = http_client.execute(httppost);
HttpEntity entity = response.getEntity();
if (entity != null)
{
InputStream instream = entity.getContent();
StringWriter writer = new StringWriter();
IOUtils.copy(instream, writer);
String theString = writer.toString();
JSONObject json = new JSONObject(theString);
// Closing the input stream will trigger connection release
instream.close();
return json;
}
}
catch (Exception e)
{
e.printStackTrace();
}
谢谢,格雷姆
最佳答案
我最终来到这里是因为我遇到了同样的问题。我最终做了以下事情:
找出用户对应用程序的确切期望。在我的例子中,它是以下内容(我认为它也是你的,因为你正在使用 AFOAuth2Client 库。
具有以下参数的 GET 请求:"URL_TO_YOUR_SERVER"?client_id=YOURCLIENTID&client_secret=YOURCLIENTESECRET&username=YOURUSERNAME&password=YOURPASSWORD&grant_type=password
是的,“grant_type”的值是登录时的密码(这意味着您将收到您的授权 token 和刷新 token )。无论回应是什么,您都需要先找出答案。在我的例子中,它是以 JSON 格式发回的数据。我将发布完成此操作的代码:
下面的方法只是用我提到的 GET 参数构造了 url。
private String getSignInURL(UserAccount accountValues){
List<NameValuePair> params = new LinkedList<NameValuePair>();
params.add(new BasicNameValuePair("client_id", accountValues.getClient_id() ));
params.add(new BasicNameValuePair("client_secret",accountValues.getClient_secret() ));
params.add(new BasicNameValuePair("grant_type", "password"));
params.add(new BasicNameValuePair("username", accountValues.getEmail() ));
params.add(new BasicNameValuePair("password", accountValues.getPassword() ));
String paramString = URLEncodedUtils.format(params, "utf-8");
return this.baseUrl+"?"+paramString;
}
以下方法进行 GET 调用。
public AuthTokens userSignIn(UserAccount accountValues)
throws Exception {
DefaultHttpClient httpClient = new DefaultHttpClient();
HttpGet httpGet = new HttpGet(this.getSignInURL(accountValues));
AuthTokens authTokens = null;
try {
HttpResponse response = httpClient.execute(httpGet);
if (response.getStatusLine().getStatusCode() != 200) {
reportException(response);
}
authTokens = getAuthTokensFromJson( getJsonFormat(response.getEntity().getContent()) );
} catch (Exception e) {
e.printStackTrace();
}
return authTokens;
}
下面生成允许您创建 JSON 对象的字符串 response.getEntity().getContent()
protected String getJsonFormat(InputStream inputStream) throws IOException{
BufferedReader reader = new BufferedReader(new InputStreamReader(inputStream, "UTF-8"), 8);
StringBuilder sb = new StringBuilder();
String line = null;
while ((line = reader.readLine()) != null)
{
sb.append(line + "\n");
}
return sb.toString();
}
最后,这里是从服务器响应中读取 authTokens 的方法。
private AuthTokens getAuthTokensFromJson(String toJson) throws IOException, JSONException {
AuthTokens authTokens = new AuthTokens();
JSONObject jObject = new JSONObject(toJson);
authTokens.setAuthToken(jObject.getString("access_token"));
authTokens.setRefreshToken(jObject.getString("refresh_token"));
return authTokens;
}
就这些了,希望对大家有帮助。
