Question

我在Play框架中工作，我正在尝试导入雅虎联系人。

我已经清除了yahoo身份验证API以获取access_token和guid。

有了这个，当我尝试使用带有auth参数的http://social.yahooapis.com/v1/user/ {guid} / contacts导入联系人时，我的页面和日志中出现了连接超时异常。

当我粘贴通过浏览器中的代码生成的相同联系人网址时，我收到的是signature_invalid

我希望我已经按照yahoo api dev notes中提到的所有内容来创建oauth_signature，但我仍然没有得到它。

有人可以帮我吗？

用于生成签名的控制器代码 -

public class Yahoo {

 private static String token = "";
 private static String currentUrl = "";
 private static String verifier = "";
 private static String tokenSecret = "";
 private static String accessToken = "";
 private static String yahooGuid = "";


public Yahoo(){
}

    if(session.contains("authorized") && session.get("authorized").equals("0")){
        session.put("authorized", "1");
        String url = getRequestTokenUrl();

        WS.WSRequest request = WS.url(url);
        Logger.info("Yahoo: Create request to get request token'%s'", request.url);

        WS.HttpResponse response = request.get();
        Logger.info("Yahoo: Token response status is %d", response.getStatus());

        if (response.getStatus() == 200){
            String[] pairs = response.getString().split("&");
            String[] tokenSecret = pairs[1].split("=");

            Yahoo.tokenSecret = tokenSecret[1];

您在浏览器上复制和粘贴时收到的签名无效，因为您没有传递oauth标头。

我强烈建议您使用lib来做到这一点，我已经完成了与Linkedin完全相同的事情： http://geeks.aretotally.in/projects/play-framework-linkedin-module

您将找到解释并链接到源代码。

希望它有所帮助。

谢谢你，费利佩
