当我执行CalendarService.setOAuthCredentials(oauthParameters,new OAuthHmacSha1Signer());我收到OAuthException 401错误未知授权标题。
我正在使用GWT + GAE我不知道为什么我收到这个错误,oauthParameters似乎没问题。
我正在使用mvp4g框架的MVP模式,对不起如果有点混乱0: - )
知道为什么我收到401错误?我认为是我正在上升的事情。通过客户端,服务器和外部页面......以及缺少的东西:-(但所有参数似乎都已正确填满。
客户端
public void onStart(){
GWT.log("onStart");
loginService.login(GWT.getHostPageBaseURL(), new AsyncCallback<LoginInfo>() {
@Override
public void onSuccess(LoginInfo result) {
Common.loginInfo = result;
if(Common.loginInfo.isLoggedIn()) {
oauthService.checkOauthTokenSecret(new AsyncCallback<String>() {
@Override
public void onSuccess(String result) {
if (result == null){
eventBus.OauthLogin();
}else{
oauthService.upgradeLogin(Window.Location.getQueryString(),Common.loginInfo, new AsyncCallback<LoginInfo>() {
@Override
public void onSuccess(LoginInfo result) {
Common.loginInfo = result;
getCitas();
}
@Override public void onFailure(Throwable caught) {
Common.handleError(caught);
}
});
}
}
@Override public void onFailure(Throwable caught) {
Common.handleError(caught);
}
});
}else{
eventBus.LoadLogin();
}
}
@Override public void onFailure(Throwable caught) {
Common.handleError(caught);
}
});
}

答案 0 :(得分:1)
我最近一直在与oAuth合作。在升级到访问令牌时,在 upgradeLogin(...)内部,您无法获取相应的访问令牌密钥。
getAccessToken()请求之后的访问令牌秘密与请求之前的访问令牌机密不同。您当前正在设置访问令牌密码(通过login.setAccessTokenSecret(oauthTS)),它是您正在使用的预先更新的访问令牌机密值。您需要将其设置为更新请求后返回的访问令牌秘密值:
String accesToken = oauthHelper.getAccessToken(oauthParameters);
String accesTokenSecret = oauthParameters.getOAuthTokenSecret();
login.setTokenSecret(accesToken);
login.setAccessTokenSecret(accesTokenSecret);
您可能还想将此更新的令牌/密钥对存储在某处。这是访问令牌密钥的值,然后应该在行中的getPublicCalendars(...)中使用:
oauthParameters.setOAuthTokenSecret(accessTokenSecret);
更新后访问令牌/密钥对是长期存在的,因此可以重新使用(无需再次更新),直到它被撤销为止。
顺便说一句,我发现oAuth Playground Tool对诊断我的问题非常有用。
我希望这有帮助,
