ES6---继续RESTful

1. POST请求，添加数据

function addTodo() {
    console.log('POST 请求');
    axios.post('http://jsonplaceholder.typicode.com/todos', {
        "title": "xiaomin is reading",
        "completed": false
    }).then(result => {
        console.log(result);
    }).catch(error => console.log(error));
}

console:

2. PUT，在url后面加上id

//PUT/patch请求
function updateTodo() {
    console.log('PUT/patch请求');
    axios.put('http://jsonplaceholder.typicode.com/todos/1', {
        title: "xiaomin is reading",
        completed: false
    }).then(result => {
        console.log(result);
    }).catch(error => {
        console.log(error);
    })
}

console:

3. PATCH请求

//PUT/patch请求
function updateTodo() {
    console.log('PUT/patch请求');
    axios.patch('http://jsonplaceholder.typicode.com/todos/1', {
        userid: 1,
        title: "xiaomin is reading",
        completed: false
    }).then(result => {
        console.log(result);
    }).catch(error => {
        console.log(error);
    })
}

console:

4. delete

//Delete请求
function removeTodo() {
    console.log('delete 请求');
    //ajax里面是 url?id=1   ===>url/1
    axios.delete('http://jsonplaceholder.typicode.com/todos/1')
        .then(result => { console.log(result); })
        .catch(error => { console.log(error); })
}

console:

5. 批量请求数据

//批量请求数据
function getData() {
    console.log('批量请求数据');
    axios.all([
        axios.get('file:///C:/Users/Administrator/Desktop/BStudy/1111.json'),
        axios.get('file:///C:/Users/Administrator/Desktop/BStudy/1112.json')
    ]).then(result => {
        console.log(result);
    });
}

console:

6. 

//批量请求数据
function getData() {
    console.log('批量请求数据');
    axios.all([
        axios.get('file:///C:/Users/Administrator/Desktop/BStudy/1111.json'),
        axios.get('file:///C:/Users/Administrator/Desktop/BStudy/1112.json')
    ]).then(axios.spread((a1, a2) => { //分发数据
        console.log(a1.data);
        console.log(a2.data);
    }))
}

console:

7. 对响应数据进行转换

console:

8.

//错误处理 
function errorHandle() {
    console.log('deal with Error 处理错误');
    axios.get('http://jsnplaceholder.typicode.com/todos')
        .then(result => {
            console.log(result);
        }).catch(error => { error })
}

console:

9. 排查

//错误处理 
function errorHandle() {
    console.log('deal with Error 处理错误');
    axios.get('http://jsnplaceholder.typicode.com/todos')
        .then(result => {
            console.log(result);
        }).catch(error => {
            if (error.request) {
                console.log(error.request);
            }
            if (error.response) {
                console.log(error.response.data);
                console.log(error.response.status);
                console.log(error.response.header);
            }
        })
}

console:

10. 404

//错误处理 
function errorHandle() {
    console.log('deal with Error 处理错误');
    axios.get('http://127.0.0.1:8080/todos')
        .then(result => {
            console.log(result);
        }).catch(error => {
            if (error.response) {
                console.log(error.response.status);
                console.log(error.response.header);
            }
            console.log(error.message);

        })
}

console:

11.

//错误处理 
function errorHandle() {
    console.log('deal with Error 处理错误');
    axios.get('/todos/1')
        .then(result => {
            if (error.response.status == 404) {
                console.log('找不到页面404');
                document.getElementById("errorDiv").innerHTML = `<span style="color:red">${找不到页面}</span>`
            };
            if (error.response.status == 500) {
                console.log('服务器有问题500');
            };
        })
