cordova-plugin-facebook4 Facebook登录未在iOS上开通

Question

我在iOS设备上遇到过cordova-plugin-facebook4（https://github.com/jeduan/cordova-plugin-facebook4）的问题。按照文档（“iOS指南”）中所示的安装过程并在Facebook Developer Console中正确配置应用程序后，当我点击我的Facebook登录按钮时，没有任何反应。 XCODE控制台输出以下错误：

2019-02-15 17:22:58.678937+0100 HelloCordovaApp[59179:1228209] Logging in with CORDOVA ... 2019-02-15 17:22:58.692742+0100 HelloCordovaApp[59179:1228209] Checking login status: unknown 2019-02-15 17:22:58.692947+0100 HelloCordovaApp[59179:1228209] Performing Fb login ... 2019-02-15 17:22:58.693087+0100 HelloCordovaApp[59179:1228209] Starting login 2019-02-15 17:22:58.693271+0100 HelloCordovaApp[59179:1228209] *** WebKit discarded an uncaught exception in the webView:decidePolicyForNavigationAction:request:frame:decisionListener: delegate: <NSInvalidArgumentException> Permissions should each be specified in separate string values in the array. 2019-02-15 17:22:58.694627+0100 HelloCordovaApp[59179:1228209] Client application failed to make a policy decision via WebPolicyDecisionListener, using defaultPolicy 2

我开发的应用程序是用AngularJs编写的，它使用Cordova包装。会是什么呢？在Android设备上它完美运行......这是用户点击我的Facebook登录按钮时执行的代码：

function fbLoginButtonClick(){
    console.log('Logging in with CORDOVA ...');
    facebookConnectPlugin.getLoginStatus(_fbLoginStatusSuccess, _fbLoginStatusError);
}

////////

function _fbLoginStatusSuccess(response) {
    var responseStatus = response.status;
    console.log('Checking login status: ', responseStatus);
    if (responseStatus === 'connected') {
      _fbLoginSuccess();
    } else if (responseStatus !== null) {
      _doFbLogin();
    } else {
      handleFacebookError(responseStatus);
    }
 }

function _fbLoginStatusError(error) {
    handleFacebookError(error);
}   

function _doFbLogin() {
    console.log('Performing Fb login ...');
    facebookConnectPlugin.login(['email, public_profile'], _fbLoginSuccess, _fbLoginError);
}

function _fbLoginSuccess(result) {
    console.log('Fb API: getting user data ...');
    facebookConnectPlugin.api('/me?fields=id,name,first_name,last_name,email', ['email', 'public_profile'], _fbApiSuccess, _fbApiError);
}

function _fbLoginError(error) {
    handleFacebookError(error);
}  

function _fbApiSuccess(userData) {
    alert('User Authenticated!!');
    //redirect to admin page
}

function _fbApiError(error) {
    handleFacebookError(error);
}

function handleFacebookError (error) {
  if(error){
    console.log(error);
  }
}

这是我的config.xml文件中的配置：

<plugin name="cordova-plugin-facebook4" spec="4.2.1">
    <variable name="APP_ID" value="************" />
    <variable name="APP_NAME" value="HelloCordovaApp" />
    <variable name="FACEBOOK_HYBRID_APP_EVENTS" value="false" />
    <variable name="FACEBOOK_ANDROID_SDK_VERSION" value="4.40.0" />
</plugin>

我花了一段时间来解决这个问题，基本上错误是你传递给SDK的权限是错误的类型。以下是解决此问题的方法：

替换此行：

facebookConnectPlugin.login(['email, public_profile'], _fbLoginSuccess, _fbLoginError);

附：

var perms = new Array("email","public_profile");
facebookConnectPlugin.login(perms, _fbLoginSuccess, _fbLoginError);

这应该可以解决您的问题。祝好运！
