【问题描述】：

IBM MobileFirst v.6.3 中 ChallengeHandler 的 submitAdapterAuthentication() 方法存在问题。

我们将回调函数分配给the options object 中的属性“onSuccess”和“onFailure”。

然后我们将 options 对象提供给 submitAdapterAuthentication(invocationData, options) 并执行它。

var ch = WL.Client.createChallengeHandler(securityTest);

//////////////////

function login (user, pass) {

  tempUser = {username: user, password: pass};
  userObj.user = user;
  var auth = "Basic " + window.btoa(user + ":" + pass);

    var invocationData = {
     parameters: [auth, user],
     adapter: "SingleStepAuthAdapter",
     procedure: "submitLogin"
    };

    var options = {
      onSuccess: iWon,
      onFailure: iLost,
      invocationContext: {invocationData: invocationData},
      timeout: 10000
    };

    ch.submitAdapterAuthentication(invocationData, options);

});

function iWon(response) {
    WL.Logger.debug('Login success! Response: ' + JSON.stringify(response));

   //update user info, as somehow isUserAuthenticated return false without it
    WL.Client.updateUserInfo(function(response) {
        WL.Logger.debug('Updated User Info success! Response: ' + JSON.stringify(response));
    });
}

function iLost(response) {
    WL.Logger.debug('ERROR. Login failed! Response: ' + JSON.stringify(response));
}

在执行 submitAdapterAuthentication(invocationData, options) 后不会调用 onSuccess (iWon) 或 onFailure (iLost)。

我们如何知道认证是否成功？

我们应该寻找和使用哪些选项、事件、回调或承诺？

我们也在此处发布了该问题： submitAdapterAuthentication not working

【问题讨论】：

是完整的JS代码吗？你错过了ch.isCustomResponse = function(response){...} 和ch.handleChallenge = function(response){...}
"我们也在这里发布了问题" - 是同一个问题吗？
他们发布了这个问题作为答案（可能很快就会被删除）

【解决方案1】：

您缺少函数的定义

ch.isCustomResponse = function(response){...}
ch.handleChallenge = function(response){...}

您的代码应该看起来更像这样

var ch = WL.Client.createChallengeHandler(securityTest);

ch.isCustomResponse = function(response) {
  if (!response||!response.responseJSON||response.responseText === null) {
       return false;
  }
     if (typeof(response.responseJSON.authRequired) !== 'undefined'){
         return true;
     } else {
         return false;
     }
};


ch.handleChallenge = function(response){
  var authRequired = response.responseJSON.authRequired;

    if (authRequired == true){
        // handle the case when authentication is needed, i.e., show login form etc.


        if (response.responseJSON.errorMessage) {
      // authentication failed, show a message to the user indicating what went wrong

      // call the login failed function or move it's contents here
      iLost(response);
    }

    } else if (authRequired == false){
          // no authentication is needed 
          ch.submitSuccess();

      // call the login success function or move it's contents here
      iWon(response);
    }
};



//////////////////

function login (user, pass) {

  tempUser = {username: user, password: pass};
  userObj.user = user;

  // is the first parameter expected by submitLogin the username or the
  // Basic Authentication encoded string ???
  var auth = "Basic " + window.btoa(user + ":" + pass);

  var invocationData = {
     parameters: [auth, user],
     adapter: "SingleStepAuthAdapter",
     procedure: "submitLogin"
  };

  ch.submitAdapterAuthentication(invocationData, {});

});


function iWon(response) {
    WL.Logger.debug('Login success! Response: ' + JSON.stringify(response));

   //update user info, as somehow isUserAuthenticated return false without it
    WL.Client.updateUserInfo(function(response) {
        WL.Logger.debug('Updated User Info success! Response: ' + JSON.stringify(response));
    });
}

function iLost(response) {
    WL.Logger.debug('ERROR. Login failed! Response: ' + JSON.stringify(response));
}
