ajax 使用get post delete put 请求restful风格接口

restfful风格：ajax请求的时候会请求两次，第一是验证请求是否符合规定的规则（百度说是对header头进行验证），请求成功返回200后再做ajax操作，个人理解

put方式：

function modifyRepairs(user,pass){
    var ret;
    $.ajax({
        url:"http://"+ apiurl +"/api/Modify/ModifyUser",
        type:"PUT",
        data:JSON.stringify(username:user,password:pass),
        dataType:"json",
        contentType:"application/json; charset=utf-8",
        async:false,
        success:function(data){
            //console.log(data.data)
            ret = data;
            //console.log(data)
        }
    });
    return ret;
}

delete:通过URL传参，使用ajax怎么试怎么报错，后来不用ajax用xml试了一下，就成功了

var url = "http://"+ apiurl +"/api/Repair/DeleteRepair?id="+id+"";
    var xhr = new XMLHttpRequest();
    xhr.open('delete',url,false);
    xhr.setRequestHeader("Content-type","application/x-www-form-urlencoded");  //必须写在open和send中间
    xhr.send();
    xhr.onreadystatechange=function(data)
    {
      console.log(data.responseText);
    };

get方式：

function manualPlan(pages,count,text){
    var ret;
    $.ajax({
        url:"http://"+apiurl+"/api/manualPlan/getPlineTime",
        header:"Content-Type: application/json",
        data:{"page":pages,"per":count,"plinenub":text},
        type:"GET",
        dataType:"json",
        async:false,
        success:function(data){
            ret = data
        }
    });
    return ret;
}

 post方式：

function removePlineTime(no,time_s,time_e,liine_nub,plan_date){
    var ret;
    var result = {timeList:[{ "no":no, "time_s": time_s, "time_e": time_e,"pline_nub": liine_nub, "plan_date": plan_date }]};
    $.ajax({
        url:"http://"+apiurl+"/api/manualPlan/removePlineTime",
        data:JSON.stringify(result),
        type:"POST",
        contentType: 'application/json;charset=utf-8',
        dataType:"json",
        async:false,
        success:function(data){
            ret = data
        }
    });
    return ret;
}
