Question

我有这个

POST api http://myIP/api/confirm

张贴姓名，文本，service_name，office_name，日期，时间

并且我想用它在React native中发布此变量

按下botton上的

发布这些变量并给我警报消息我怎样才能做到这一点这是我的反应本机代码

<View>
  <Text> {this.props.navigation.state.params.name}- {this.props.navigation.state.params.text} </Text>
  <Text> {this.props.navigation.state.params.service_name}</Text>
  <Text>{this.props.navigation.state.params.office_name}</Text>
  <Text>{this.props.navigation.state.params.date}</Text>
  <Text{this.props.navigation.state.params.time} </Text> 

  <Button rounded
     title='next'
     onPress={() => {
     Alert.alert('The Appointment booked') }} /> 
</View>

您可以执行以下

fetch("http://myIP/api/confirm", {
  method: "POST",
  headers: {
    Accept: "application/json",
    "Content-Type": "application/json"
  },
  body: JSON.stringify({
    firstParam: "yourValue",
    secondParam: "yourOtherValue"
  })
})
  .then(response => response.json())
  .then(responseJson => {
    Alert.alert(
      "Alert Title",
      "My Alert Msg",
      [
        {
          text: "Cancel",
          onPress: () => console.log("Cancel Pressed"),
          style: "cancel"
        },
        { text: "OK", onPress: () => console.log("OK Pressed") }
      ],
      { cancelable: false }
    );
  })
  .catch(error => {
    console.error(error);
  });

但是请从react-native导入警报

在发布时将变量发布到数据库（本机反应）
