可传参数

axios({
        //请求方式 get post delete put
        method:"",
        //请求地址
        url:"",
        //query 参数
        params:{

        },
        // body参数
        data:{

        },
        //请求头 一般是用来指定请求传参格式
       
        //请求中没有 data参数 所以headers content-type 默认为 content-type: "application/json;charset=UTF-8"
        // headers: {
        //   // 'content-type': 'application/json;charset=UTF-8'（默认）
        //   "Content-Type": "application/x-www-form-urlencoded",
        // 'content-type':"multipart/form-data"
        // },
        
        headers:{},
      }).then(function(res){
        console.log(res)
      })
    }

get请求

query

如何区分是不是get请求中的query请求？

第一种 params方式

// params 对象内写形式
getInstructorById1(id) {
      axios({
        method: "get",
        url: "http://localhost:8080/instructor/getInstructorById",
        params: {
          id: id,
          //如果 key value名字相同可简写 例如 id:id可以写为 id
        },
      }).then(function (res) {
        console.log(res);
      });
    },

//params 对象外写形式
    getInstructorById3(id) {
      const params = {
        id: id,
        //如果 key value名字相同可简写 例如 id:id可以写为 id
      };
      axios({
        method: "get",
        url: "http://localhost:8080/instructor/getInstructorById",
        params,
      }).then(function (res) {
        console.log(res);
      });
    },

第二种 拼接方式

 //?a="a"&b="b" 拼接形式
 getInstructorById2(id) {
      axios({
        method: "get",
        url: `http://localhost:8080/instructor/getInstructorById?id=${id}`,
        //与下面两种写法都可以
        // url: "http://localhost:8080/instructor/getInstructorById?id=" + id,
      }).then(function (res) {
        console.log(res);
      });
    },

path

如何区分是Get中的path形式

//path
    getById1(id) {
      axios({
        method: "get",
        // url: "http://localhost:8080/instructor/getById/" + id,
        //两种写法都可以
        url: `http://localhost:8080/instructor/getById/${id}`,
      }).then(function (res) {
        console.log(res);
      });
    },

post请求

query

如何区分是post query请求

第一种 params

//post params
    add1(id) {
      axios({
        method: "post",
        url: "http://localhost:8080//instructor/add",
        params: {
          id: id,
          name: "jhj",
        },
      }).then((res) => {
        console.log(res);
      });
    },

第二种 formdata

 add2(id) {
      const params = {
        id,
        name: "jhj",
      };
      axios({
        method: "post",
        url: "http://localhost:8080//instructor/add",
        data:params,
        headers:{
          'content-type':"multipart/form-data"
        }
      }).then((res) => {
        console.log(res);
      });
    },

add3(id) {
      const data=new FormData();
      data.append("name","jhj")
      data.append("id",id)
      axios({
        method: "post",
        url: "http://localhost:8080//instructor/add",
        data:data,
      }).then((res) => {
        console.log(res);
      });
    },

body

如何区分 是body post请求

addbody(id) {
      axios({
        method: "post",
        url: `http://localhost:8080/instructor/addbody`,
        data: {
          id: id,
          name: "jhj",
        },
        //请求中没有 data参数 所以headers content-type 默认为 content-type: "application/json;charset=UTF-8"
        // headers: {
        //   // 'content-type': 'application/json;charset=UTF-8' 默认
        //   // "Content-Type": "application/x-www-form-urlencoded",
        //   // "content-type":"multipart/form-data"
        // },
      }).then(function (res) {
        console.log(res);
      });
    },

header

putheader(id) {
      axios({
        method: "post",
        url: `http://localhost:8080/instructor/putheader`,

        //自定义header
        headers: {
          // 'content-type': 'application/json;charset=UTF-8'
          // "Content-Type": "application/x-www-form-urlencoded",
          // "content-type":"multipart/form-data"
          myheader: id,
        },
      }).then(function (res) {
        console.log(res);
      });
    },

delete

 //deleted params
    del1(id) {
      axios({
        method: "delete",
        url: "http://localhost:8080/instructor/delete",
        params: {
          id: id,
          //如果 key value名字相同可简写 例如 id:id可以写为 id
        },
      }).then(function (res) {
        console.log(res);
      });
    },

put

put query

put(id) {
      axios({
        method: "put",
        url: `http://localhost:8080/instructor/put`,
        params: {
          id: id,
          name: "jhj",
        },
      }).then(function (res) {
        console.log(res);
      });
    },

put body

 putbody(id) {
      axios({
        method: "put",
        url: `http://localhost:8080/instructor/putbody`,
        data: {
          id: id,
          name: "jhj",
        },
      }).then(function (res) {
        console.log(res);
      });
    },

综合

all(id) {
      axios({
        method: "post",
        url: `http://localhost:8080/instructor/all/${id}`,
        params: {
          ids:id
        },
        data: {
          id,
          name: "jhj",
        },
        //自定义header
        headers: {
          // 'content-type': 'application/json;charset=UTF-8'
          // "Content-Type": "application/x-www-form-urlencoded",
          // "content-type":"multipart/form-data"
          myheader: id,
        },
      }).then(function (res) {
        console.log(res);
