Axios传值的几种方式

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

<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>
