因此,我正在为学校开发应用程序,而在一个问题上停留了大约两天。我正在建立一个从TMDB获取数据的搜索,并且一切正常。当我输入输入时,所有数据都会流入!但是,当我提交并尝试重定向到/ results页面时,该页面链接到在定向到该页面时显示SearchResults的组件,没有任何反应,它停留在主页上。 ,否则我不应该在这种情况下使用它。这是我的搜索组件的代码,如果您能帮助我,我将不胜感激!:
import React, { Component, Redirect } from 'react';
import axios from 'axios';
class Search extends Component {
state = {
query: '',
results: []
};
getInfo = () => {
axios
.get(
`https://api.themoviedb.org/3/search/tv?api_key=6d9a91a4158b0a021d546ccd83d3f52e&language=en-US&query=${
this.state.query
}&page=1`
)
.then(({ data }) => {
this.setState({
results: data
});
});
};
handleInputChange = e => {
e.preventDefault();
this.setState(
{
query: this.search.value
},
() => {
if (this.state.query && this.state.query.length > 1) {
if (this.state.query.length % 2 === 0) {
this.getInfo();
}
} else if (!this.state.query) {
}
}
);
};
render() {
return (
<div>
<form>
<input
className='search'
placeholder='⌕'
type='text'
ref={input => (this.search = input)}
onChange={this.handleInputChange}
/>
</form>
{this.state.results.length > 0 && (
<Redirect
to={{
pathname: '/results',
state: { results: this.state.results }
}}
/>
)}
</div>
);
}
}
export default Search;
最佳答案
您可以使用withRouter
获取历史道具注入,然后执行:history.push(“/results”)
该代码将如下所示:
import React, { Component, Redirect } from 'react';
import axios from 'axios';
import { withRouter } from "react-router";
class Search extends Component {
state = {
query: '',
results: []
};
componentDidUpdate(prevProps, prevState) {
const { history } = this.props;
if (prevState.results !== this.state.results) {
history.push('/results');
}
}
getInfo = () => {
axios
.get(
`https://api.themoviedb.org/3/search/tv?api_key=6d9a91a4158b0a021d546ccd83d3f52e&language=en-US&query=${
this.state.query
}&page=1`
)
.then(({ data }) => {
this.setState({
results: data
});
});
};
handleInputChange = e => {
e.preventDefault();
this.setState(
{
query: this.search.value
},
() => {
if (this.state.query && this.state.query.length > 1) {
if (this.state.query.length % 2 === 0) {
this.getInfo();
}
} else if (!this.state.query) {
}
}
);
};
render() {
return (
<div>
<form>
<input
className='search'
placeholder='⌕'
type='text'
ref={input => (this.search = input)}
onChange={this.handleInputChange}
/>
</form>
</div>
);
}
}
export default withRouter(Search);
通过这种方式,您可以使用React路由器历史记录中的push方法以编程方式进行导航。
