Question

如何获取用户ID邮件图片等？图片非常重要。我已经尝试过不同的示例，但是它们没有用。我想在第二个屏幕上显示图片，但目前还不重要。很抱歉，我对此并不陌生，真的不知道该怎么办。

  import React from 'react';
  import {
    StyleSheet,
    Text,
    View,
    Button,
    Alert,

  EStyleSheet.build({
      $textColor: 'white'
    });


  export default class HomeScreen extends React.Component {

          super(props);
          this.state = {userInfo: null,};
      }
      static navigationOptions = {

                <Image source={{url: this.state.userInfo.photoURL}} />
              </View>

      if (type === 'success') {

        const userInfo = await response.json();
        this.setState({userInfo});
        this.renderImage();
      } else {
        // type === 'cancel'
      }
    } catch ({ message }) {
      alert(`Facebook Login Error: ${message}`);
    }

              <View style={styles.container}><TouchableOpacity style={[styles.buttons, {backgroundColor: '#3b5998'}]} onPress={this.loginWithFacebook.bind(this)}>
              <Image style={styles.img} source={require("../assets/Facebook.png")}/><Text style={{left: 20, color: 'white'}}>Facebook</Text>

          );
      }
  }
  })

那是调试消息： {错误：{…}} 错误： {消息：“语法错误”，而不是字符20处的字符串的预期结尾，而不是“（”。”，id，名称，图片，类型（大）”，类型：“ OAuthException”，代码：2500，fbtrace_id：“ DXFuk9C8gdT”} 原始：对象

Answer 1

语法错误告诉您API调用有问题：

错误

picture,type(large)

正确

picture.type(large)

顺便说一句，您可以（而且应该）始终先在API资源管理器中尝试API调用：https://developers.facebook.com/tools/explorer/

Answer 2

您不需要额外的请求。

只需这样做。

firebase.auth().signInAndRetrieveDataWithCredential(credential)
.then(data => {
  let {photoURL} = data.user
  // now you got the photoURL
  // to retrieve different sizes of photo url simply do
  let largerImage = photoURL+"?height=600"
})

一个简单的请求。

height = 600将根据原始照片的width＆height属性调整照片尺寸，并返回适当的图像尺寸。它将返回600以上，但不会低于600。由于图像可能不是正方形格式。
