uniapp中请求接口问题

//GET-请求数据
getInfo(){
    uni.request({
          url: `${this.$baseUrl}/api-demo/getDemoById?lid=${lid}&page=${this.page}&pagesize=${this.pagesize}`,  //这里的lid,page,pagesize只能是数字或字母
          method: 'GET',
          success: (res)=>{},
          fail: (err)=>{}
    })
}

//POST-发送json格式请求
sendInfo(){
    let params = {
          "phone":this.userphone,
          "name":this.username
    }
    uni.request({
          url: `${this.$baseUrl}/api-demo/send`,
          method: 'POST',
          data: params,
          success: (res)=>{},
          fail: (err)=>{}
    })  
}

//POST-发送FormData格式请求
sendInfo(){
    let params = {
          "phone":this.userphone,
          "name":this.username
    }
    let headers={
          "Content-Type":"application/x-www-form-urlencoded"  //设置一下请求头即可
    }
    uni.request({
          url: `${this.$baseUrl}/api-demo/send`,
          method: 'POST',
          header: headers,
          data: params,
          success: (res)=>{},
          fail: (err)=>{}
    })  
}

//请求接口时携带token
sendInfo(){
    let params = {
          "phone":this.userphone,
          "name":this.username
    }
    let headers={
          "Content-Type":"application/x-www-form-urlencoded",
          "Token":`this.userToken`   //设置一下token即可
    }
    uni.request({
          url: `${this.$baseUrl}/api-demo/send`,
          method: 'POST',
          header: headers,
          data: params,
          success: (res)=>{},
          fail: (err)=>{}
    })  
}
