带松弛的ServiceNow集成

Question

我需要将servicenow与松弛集成在一起，这有助于向松弛通道发送高且关键的P1警报。

我正在寻找的可能性，可以做，以使serviceNow与松弛集成。

请建议一下。

Answer 1

您应该在ServiceNow中在insert/update上创建业务规则。

条件:优先级=1或优先级ChangesTo 1

高级/脚本：

    var request = new sn_ws.RESTMessageV2('SLACK_EndpointURL', 'POST');
request.setRequestHeader("Accept","application/json");
request.setRequestHeader('Content-Type','application/json');
//OR METHOD # request.setEndpoint('SLACK_EndpointURL');

// Your message
var reqBody = '{\"text\":\"This is a line of text.\nAnd this is another one.\"}';       
request.setRequestBody(reqBody);

var response = request.execute();
var responseBody = response.getBody();

//See response in System Logs # gs.log(responseBody);

Answer 2

集成ServiceNow和Slack有多种方法。但是，对于您的情况，一种简单而直接的方法是在WebHook中创建一个传入的ServiceNow，它提供了一个URL，而从您的ServiceNow实例所需要做的就是将JSON发布到该URL。

您可以使用BR触发所需的条件。这个函数将我们的消息发布到Slack。端点是在Slack中创建的入站web钩子地址：

function postMessage(inPayload, inEndpoint, inTimeout) {
    var sResponseBody = '', nResponseCode = 0, sResponseMessage = '', sResponseEndpoint = '', sResponseHeaders = [];

    var rest = new sn_ws.RESTMessageV2();
    rest.setEndpoint(inEndpoint);
    rest.setHttpTimeout(inTimeout);
    rest.waitForResponse(inTimeout);
    rest.setRequestHeader('Content-Type', 'application/json');
    rest.setRequestHeader('Accept', 'application/json');
    rest.setHttpMethod('post');
    rest.setRequestBody(inPayload);
    for ( var i = 0; i < 3; i++ ) {
    try {
        var response      = rest.execute();
        sResponseBody     = response.getBody();
        nResponseCode     = response.getStatusCode();
        sResponseEndpoint = response.getEndpoint();
        sResponseHeaders  = response.getRequestHeaders();
        break;
    } catch( err ) {
        sResponseMessage = err.getMessage();
        gs.sleep(5000);
    }
    }
    return {"ResponseCode":nResponseCode,"ResponseBody":sResponseBody,"ResponseMessage":sResponseBody,"ResponseEndpoint":sResponseEndpoint, "ResponseHeaders":sResponseHeaders};
}

下面是我们使用的一个有效载荷示例。${tag}是我们用来从源票证中获取值的简单宏。你只需在BR中做点什么。

{
    "username":"${SlackUsername}",
    "attachments":[{
            "title":"Short description",
            "title_link":"${URL}",
            "text":"${ShortDescription}",
            "fallback":"${ShortDescription}",
            "color":"${Color}",
            "footer":"${SlackUsername}",
            "fields":[
                {"title":"State","value":"${State}","short":true},
                {"title":"Priority","value":"${Priority}","short":true},
                {"title":"Assignment group","value":"${AssignmentGroup}","short":true},
                {"title":"Assigned to","value":"${AssignedTo}","short":true},
                {"title":"Technical Service","value":"${TechnicalService}","short":true},
                {"title":"Configuration item","value":"${ConfigurationItem}","short":true},
                {"title":"Details","value":"${Description}","short":false}
            ],
            "ts":"${TimeStampEpoch}"
        }
    ]
}

关于信息:我们使用一个自定义表，并设置了条件以触发将post发送到Slack。用户可以根据需要创建自己的过滤器。所使用的端点是用户提供的入站web钩子。异步业务规则在任务上运行，以检查所需的条件和操作。

目前的工作是使用Slack，以便我们可以张贴到任何频道的id。这意味着我们不会冒险有人创建一个入站的web钩子然后离开公司。
