如何解决如何为我的联系页面制作成功的 ulr
我希望客户端被重定向到另一个 HTML 页面，作为我联系表单中成功发送的消息。但我不知道这里到底出了什么问题。我无法重定向到我的成功页面，但表单有效。 #我的主应用程序的 url.py
urlpatterns = [
path('^contact/',include('contactus.urls')),]
#我的联系人应用 url.py
from __future__ import unicode_literals
from django.conf.urls import url

解决方法
错误可能来自视图。
试试：
/* eslint-disable semi */
/* eslint-disable prettier/prettier */
import React,{Component} from 'react';
import {View,Text,ToastAndroid,FlatList} from 'react-native';
class Location extends Component {
constructor(props) {
super(props);
this.state = {
location_id: null,locations: [],isLoading: true,};
}
componentDidMount = () => {
this.props.navigation.addListener('focus',() => {
this.state.isLoading;
});
this.getData();
}
getData = async () => {
const loc_id = this.props.route.params.location_id;
return await fetch('http:10.0.2.2:3333/api/1.0.0/location/' + loc_id,{
method: 'get','headers': {
'Content-Type': 'application/json',},})
.then((response) => {
if (response.status === 200) {
return response.json();
} else if (response.status === 404) {
ToastAndroid.show('Unable to locate location',ToastAndroid.SHORT);
} else {
throw 'something went wrong';
}
})
.then((responseJson) => {
console.log(responseJson);
this.setState({
locations: responseJson,isLoading: false,});
})
.catch((error) => {
ToastAndroid.show(error.toString(),ToastAndroid.SHORT);
});
}
render() {
if (this.state.isLoading) {
return (
<View>
<Text>Loading...</Text>
</View>
)
} else {
return (
<View>
<View>
<Text>Location ID: {this.props.route.params.location_id}</Text>
<Text>Name: {this.state.locations.location_name}</Text>
<Text>City: {this.state.locations.location_town}</Text>
<Text>Overall rating: {this.state.locations.avg_overall_rating}</Text>
</View>
<View>
<FlatList
data={this.state.locations}
renderItem={({item}) => (
<View style={{margin: 10,padding: 10}}>
<View>
<Text>ID: {parseInt(item.location_id)}</Text>
</View>
<View>
<Text>Rating: {item.avg_overall_rating}</Text>
<Text>Town: {item.location_town}</Text>
<Text>Location Review: {item.location_reviews.review_id}</Text>
</View>
<View>
<Text>Name: {item.location_name}</Text>
<Text>Location Review: {item.location_reviews.map(items => items.review_id)}</Text>
<Text>Location Review: {item.location_reviews.map(items => items.review_body)}</Text>
</View>
</View>
)}
keyExtractor={(item) => item.location_id.toString()}
/>
</View>
</View>
);
}
}
}
export default Location;
或者你可以保持这样的视图并将 urls.py 中的 url 更改为：
success_url = "/success/"
