Question

我正在尝试使用ajax调用在nagios中安排服务的停机时间。我可以通过NAgios GUI安排它，并找到一种方法来使用curl进行调度。

我找到了一个链接How to set downtime for any specific nagios host for certain time from commandline through curl?，它解释了如何通过curl命令实现它。

我试图通过curl命令实现它。

curl \
--data cmd_typ=56 \
--data cmd_mod=2 \
--data host=jenkins \
--data "service=Jenkins+PROD+GUI" \
--data "com_author=Nagios Admin"\
--data "com_data=Test" \
--data trigger=0 \
--data "start_time=05-09-2018+14%3A05%3A14" \
--data "end_time=05-09-2018+16%3A05%3A14" \
--data fixed=1 \
--data btnSubmit=Commit \
http://xx.xx.xx:8087/nagios/cgi-bin/cmd.cgi -u "nagiosadmin:nagiosadmin"

工作正常。

我尝试将相同的curl功能转换为ajax post call。

HTML :

<form name="NAME" id="avialform" class="avail" action="">
            <fieldset id="availfield">
                <legend style="color:white" id="availegend">SCHEDULED DOWNTIME</legend>
                    <table width="100%" cellpadding="0" cellspacing="0" class="vzuui-detailpanel">
                        <tr>
                            <td><label>Service :</label>
                                <select id = "ServiceList">
                                    <option value = "Jenkins+PROD+GUI">Jenkins Prod</option>
                                </select>
                            </td>   
                        </tr>
                        <tr>
                        <td><label>From Date :</label><input id="from" type="datetime-local" name="fromdate" /></td>
                        </tr>
                        <tr>
                            <td><label>To Date :</label><input id="to" type="datetime-local" name="todate" /></td>
                        </tr>
                        <tr>
                            <td><label>Comment :</label><input id="comment" type="text" name="Servicecommt" /></td>
                        </tr>
                    </table>
            </fieldset>  
        <button class="vzuui-btn-red-active" type="button" id="getrepo">Submit</button>
    </form>

Ajax:

        var posdata = {"cmd_typ":56,"cmd_mod":2,"host":"jenkins","service":"Jenkins+PROD+GUI","com_author":"Nagios Admin","com_data":"Test","trigger":0,"start_time":"2018-05-09T18:00","end_time":"2018-05-09T19:00","fixed":1,"btnSubmit":"Commit"}
                    posdata["service"] = select.options[select.selectedIndex].value;
                    posdata["com_data"] = document.getElementById("comment").value;
                    posdata["start_time"] = document.getElementById("from").value;
                    posdata["end_time"] = document.getElementById("to").value;
                    console.log(JSON.stringify(posdata));
                    $.support.cors = true;    

    $.ajax({
                        url: "http://xx.xx.xx:8087/nagios/cgi-bin/cmd.cgi",
                        beforeSend: function (xhr) {
                                            xhr.setRequestHeader('Authorization',
                                            make_base_auth("nagiosadmin", "nagiosadmin"));
                                        },
                        type: 'POST',
                        dataType: 'json',
                        contentType: 'application/json',
                        processData: false,
                        data: posdata,
                        success: function (data) {
                          alert(JSON.stringify(data));
                        },
                        error: function(){
                          alert("Cannot get data");
                        }
                    });

但是我收到了500内部服务器错误。请指导我使用ajax实现这一目标。

似乎数据应该作为表单而不是json发送。删除contentType: 'application/json'，它应该可以正常工作

contentType（默认值：'application / x-www-form-urlencoded; charset = UTF-8'）

类型：布尔值或字符串

将数据发送到服务器时，请使用此内容类型。默认为“application / x-www-form-urlencoded;

您应该按照以下更新代码

var posdata = {
    "cmd_typ": 56,
    "cmd_mod": 2,
    "host": "jenkins",
    "service": "Jenkins+PROD+GUI",
    "com_author": "Nagios Admin",
    "com_data": "Test",
    "trigger": 0,
    "start_time": "2018-05-09T18:00",
    "end_time": "2018-05-09T19:00",
    "fixed": 1,
    "btnSubmit": "Commit"
}
posdata["service"] = select.options[select.selectedIndex].value;
posdata["com_data"] = document.getElementById("comment").value;
posdata["start_time"] = document.getElementById("from").value;
posdata["end_time"] = document.getElementById("to").value;
console.log(JSON.stringify(posdata));
$.support.cors = true;

$.ajax({
    url: "http://xx.xx.xx:8087/nagios/cgi-bin/cmd.cgi",
    beforeSend: function(xhr) {
        xhr.setRequestHeader('Authorization',
            make_base_auth("nagiosadmin", "nagiosadmin"));
    },
    type: 'POST',
    data: posdata,
    success: function(data) {
        alert(JSON.stringify(data));
    },
    error: function() {
        alert("Cannot get data");
    }
});

将确保数据为application/x-www-form-urlencoded并且jQuery还会检查响应并确定类型

使用ajax POST
