我正在从本地Mock-API获取数据。服务器发送的数据具有以下格式:
module.exports = [
{
username: "george",
email: "george@test.com",
group: "foo",
loggedIn: true
},
{
username: "nick",
email: "nick@test.com",
group: "bar",
loggedIn: false
}
];
基本上,您可以看到用户列表。每个用户的唯一ID是他们的username
。在我的ReactJS U.I中,我有一个用户列表。当我单击其中一个用户时,我将重定向到新页面,并且url会根据我单击的用户的数量而更改
但是我无法获取有关该用户的任何数据。我得到一个用JSON.Stringify
打印的空字符串。这是我的编码:
/* eslint-disable react/prefer-stateless-function */
import React, { Component, Fragment } from 'react';
import PropTypes from 'prop-types';
import PageHeader from './PageHeader';
import Breadcrumb from './Breadcrumb';
import Role from 'shared/common/enums/Role';
import { getUser } from '../../config/service';
class UserDetailsScreen extends Component {
state = {
inEditMode: false,
user: {},
error: null
};
componentDidMount() {
this.fetchUser();
}
fetchUser = () => {
getUser().then(({ data }) => {
this.setState({ user: data });
});
};
render() {
const {user } = this.state;
return (
<div className="container-fluid">
<div><pre>{JSON.stringify(user, null, 2)}</pre></div>
{user && (
<Fragment>
<Breadcrumb
items={[
{
name: 'Users',
url: 'users'
},
{
name: user.username,
url: `${user.username}`
}
]}
/>
<h1 className="heading-title">{user.username}</h1>
)}
</div>
);
}
}
export default UserDetailsScreen;
getUser()
是在我的本地端点上侦听的函数。这是端点:GET_USER: name =>
http://localhost:5000/api/user/ $ {name} ,
。
这是getUser()
:
export const getUser = name => {
const options = {
method: httpMethod.GET,
url: endpoint.GET_USER(name)
};
return instance(options);
};
这是Dyson Server实例,用于使用用户名作为唯一ID来获取特定用户:
const users = [
{
username: "george",
email: "george@test.com",
group: "foo",
loggedIn: true
},
{
username: "nick",
email: "nick@test.com",
group: "bar",
loggedIn: false
}
]
module.exports = {
path: '/api/user/:username',
method: 'GET',
template: (pathParameters) => {
return users.find((user) => {
return user.username === pathParameters.username;
})
}
};
您看到任何错误吗?
答案 0 :(得分:1)
您没有在getUser()
中传递'name'参数,请尝试传递:
fetchUser = () => {
getUser('USERNAME').then(({ data }) => {
this.setState({ user: data });
});
};
