Javascript 将JSON数据传递到react native中的下一页

我是一个初学者，仍在学习如何反应

在我的react原生应用程序中，我有两个屏幕。 在第一页中，我有JSON数据[从live server获取]； 我想把这个JSON数据传递到下一个页面

我使用react导航在页面之间导航。 我将一个数据[手机号码]传递到下一页

但我不知道如何将JSON数据传递到下一页

第一页代码：[包含JSON数据]

constructor(props) { 
    super(props) 
    this.state = {

    UserMNO: ''
    } 
  }

  UserLoginFunction = () =>{

 const { UserMNO } = this.state;
 const {firstname} = this.state;
 const {lastname} = this.state;
 const {email} = this.state;
 const {profession} =this.state;

fetch('http://demo.weybee.in/react/User_Login.php', {
  method: 'POST',
  headers: {
    'Accept': 'application/json',
    'Content-Type': 'application/json',
  },
  body: JSON.stringify({

  mobileno: UserMNO,

      })

}).then((response) => response.json())
      .then((responseJson) => {
        // If server response message same as Data Matched
       if(responseJson != 'Enter valid phone number' )
        {   

            console.log(responseJson[0]);
            console.log(responseJson[1]);
            console.log(responseJson[2]);
            console.log(responseJson[3]);
            //Then open Profile activity and send user email to profile activity.
            this.refs.toast.show('Login successful', 500, () => {
            const { navigation } = this.props;

            const { UserMNO }  = this.state ;

            navigation.navigate("Profile",

错误

不传递任何内容

您可以按如下方式发送响应JSON：

navigation.navigate(
              "Profile", 
              {mobileno: UserMNO, myJSON: responseJson} 
);

并在第二个屏幕中显示：

const responseJson = this.props.navigation.getParam("myJSON");

您可以使用参数mobileno进行导航。它被传递，正如您所看到的，输入被填充。其他参数是空的，因为您没有将其放在导航参数中，所以我看不到problem@AakashThoriya是的，您可以传递，然后您将收到json数组的第一个对象。最后，数据成功传递！谢谢你贡献了宝贵的时间
