<script src="https://unpkg.com/axios/dist/axios.min.js"></script>
</body>
axios基本使用
默认是get请求
注意:get请求无请求体,可以有body,但是不建议带
使用get方式进行无参请求
<script>
axios({
url:'http://localhost:8080/get/getAll',
method:'get'
}).then(res=>{
console.log(res.data.data)
})
</script>
@GetMapping("/get/getAll")
public ResResult getAllUser(){
List<User> list = userService.list();
return ResResult.okResult(list);
}
使用get方式请求,参数值直接放在路径中
<script>
axios({
url:'http://localhost:8080/get/1',
method:'get'
}).then(res=>{
console.log(res.data.data)
})
</script>
后端接口
@GetMapping("/get/{id}")
public ResResult getUserById(@PathVariable("id") Long id){
User user = userService.getById(id);
return ResResult.okResult(user);
}
使用get方式请求,参数拼接在路径中:方式①
<script>
axios({
url:'http://localhost:8080/get?id=1',
method:'get'
}).then(res=>{
console.log(res.data.data)
})
</script>
后端接口
@GetMapping("/get")
public ResResult getUserByIds(@RequestParam("id") Long id){
User user = userService.getById(id);
return ResResult.okResult(user);
}
使用get方式请求,参数拼接在路径中:方式②
<script>
axios({
url:'http://localhost:8080/get',
params:{
id:'2'
},
method:'get'
}).then(res=>{
console.log(res.data.data)
})
</script>
后端接口
@GetMapping("/get")
public ResResult getUserByIds(@RequestParam("id") Long id){
User user = userService.getById(id);
return ResResult.okResult(user);
}
使用get方式请求,拼接多个参数在路径中:方式③
<script>
axios({
url:'http://localhost:8080/get',
params:{
id:'2',
username:'swx'
},
method:'get'
}).then(res=>{
console.log(res.data.data)
})
</script>
后端接口
@GetMapping("/get")
public ResResult getUserByIds(@RequestParam("id") Long id,@RequestParam("username") String username){
LambdaQueryWrapper<User> wrapper = new LambdaQueryWrapper<>();
wrapper.eq(User::getUsername,username);
wrapper.eq(User::getId,id);
User user = userService.getOne(wrapper);
return ResResult.okResult(user);
}
post请求接收json格式数据
<script>
axios({
url:'http://localhost:8080/post/test',
data:{
'username':'swx'
},
method:'post'
}).then(res=>{
console.log(res.data.data)
})
</script>
后端接口
@PostMapping("/post/test")
public ResResult getUserByIdPostTest(@RequestBody User user){
LambdaQueryWrapper<User> wrapper = new LambdaQueryWrapper<>();
wrapper.eq(User::getUsername,user.getUsername());
User users = userService.getOne(wrapper);
return ResResult.okResult(users);
}
3、请求简写方式&请求失败处理
get无参请求
<script>
axios.get('http://localhost:8080/get/getAll').then(res=>{
console.log(res.data.data)
}).catch(err=>{
console.log('timeout')
console.log(err)
})
</script>
get有参请求,post方式不可以这样请求
<script>
axios.get('http://localhost:8080/get',{params:{id:'2',username:'swx'}}).then(res=>{
console.log(res.data.data)
}).catch(err=>{
console.log('timeout')
console.log(err)
})
</script>
post有参请求,以json格式请求
<script>
axios.post('http://localhost:8080/post',"id=2&username=swx").then(res=>{
console.log(res.data.data)
}).catch(err=>{
console.log('timeout')
console.log(err)
})
</script>
也可以一下方式,但是后端要加@RequestBody注解
<script>
axios.post('http://localhost:8080/post/test',{username:'swx'}).then(res=>{
console.log(res.data.data)
}).catch(err=>{
console.log('timeout')
console.log(err)
})
</script>
axios并发请求
<script>
axios.all([
axios.get('http://localhost:8080/get/getAll'),
axios.get('http://localhost:8080/get/get',{params:{id:'1'}})
]).then(res=>{
//返回的是数组,请求成功返回的数组
console.log(res[0].data.data),
console.log(res[1].data.data)
}).catch(err=>{
console.log(err)
})
</script>
后端接口
@GetMapping("/get/getAll")
public ResResult getAllUser(){
List<User> list = userService.list();
return ResResult.okResult(list);
}
@GetMapping("/get/get")
public ResResult getUserByIdt(@RequestParam("id") Long id){
User user = userService.getById(id);
return ResResult.okResult(user);
}
方式2:使用spread方法处理返回的数组
<script>
axios.all([
axios.get('http://localhost:8080/get/getAll'),
axios.get('http://localhost:8080/get/get',{params:{id:'1'}})
]).then(
//高端一些
axios.spread((res1,res2)=>{
console.log(res1.data.data),
console.log(res2.data.data)
})
).catch(err=>{
console.log(err)
})
</script>
axios全局配置
<script>
axios.defaults.baseURL='http://localhost:8080'; //全局配置属性
axios.defaults.timeout=5000; //设置超时时间
//发送请求
axios.get('get/getAll').then(res=>{
console.log(res.data.data)
});
axios.post('post/getAll').then(res=>{
console.log(res.data.data)
});
</script>
axios实例 文章来源:https://www.toymoban.com/news/detail-854677.html
<script>
//创建实例
let request = axios.create({
baseURL:'http://localhost:8080',
timeout:5000
});
//使用实例
request({
url:'get/getAll'
}).then(res=>{
console.log(res.data.data)
});
request({
url:'post/getAll',
method:'post'
}).then(res=>{
console.log(res.data.data)
})
</script>
