React Native FBSDK中的AccessToken问题 [英] Issues with the AccessToken in the React Native FBSDK

问题描述

我无法在React Native的 fbsdk 中获取AccessToken.

I am having trouble with my ability to get the AccessToken in the fbsdk in React Native.

我正在调用Facebook建议的核心:

I am calling the core as suggested by Facebook:

const FBSDKCore = require('react-native-fbsdkcore');
const {
  FBSDKAccessToken,
} = FBSDKCore;

在一种情况下，我尝试按照SO此处所述的类似问题建议将令牌写入日志.

And in one scenario I try to write the token in the log as suggested by a similair question stated here on SO.

    <View>
        <View style={{flex: 1, alignItems: 'center', padding: 50, marginTop: 250}}>
        <View> 
          <LoginButton
            publishPermissions={["publish_actions"]}
            onLoginFinished={
              (error, result) => {
                if (error) {
                  alert("login has error: " + result.error);
                } else if (result.isCancelled) {
                  alert("login is cancelled.");
                } else {
                  FBSDKAccessToken.getCurrentAccessToken((token)=> {
                        console.log(token);
                      });                          
                  Actions.Navigator()
                }
              }
            }
            onLogoutFinished={() => {
              alert("logout.")}}/>
        </View>
        </View>
    </View>

这给了我红屏未定义不是对象(正在评估FBSDKAccessTokenInterface.getCurrentAccessToken)

This gives me the redscreen "undefined is not an object (evaluating the FBSDKAccessTokenInterface.getCurrentAccessToken)

尝试在应用程序的其他部分中实现类似功能，当然首先要定义const FBSDKAccessToken ，然后调用 userID (这应该是 FBSDKCore )如下:

Trying to pull off something similair in other parts of the app, of course defining the const FBSDKAccessToken first, then calling the userID (which should be a part of the FBSDKCore) as:

<Text style={{fontSize: 18, color:colors.General.navtext}}>{FBSDKAccessToken.userID}</Text>

什么也不做，我认为它可以返回已登录用户的userID.另外，如果我尝试在与以下位置相同的位置写出访问令牌:

Yields nothing, where I believed it to return the userID of the logged in user. Also, if I try to write out the accesstoken in that same place as:

<Text style={{fontSize: 18, color:colors.General.navtext}}>{FBSDKAccessToken.getCurrentAccessToken()}</Text>

我得到和以前一样的红色屏幕.

I get the same red screen as before.

我试图查看库的链接，但这甚至引起了进一步的问题.

I tried to look in to the linking of libraries, but that even caused further problem.

因此，因此，我非常困倦，对于出现问题的反馈，我将非常感谢.

Hence, from this, I am pretty stranded and I would really appreciate some feedback on what has gone wrong.

推荐答案

尝试一下.

console.log(token.accessToken.toString());
