我正在尝试使用http post方法在servicenow中创建一个事件。我使用HTTP post方法，通过使用JSON发送事件创建数据。 如下：
HttpPost httpPost = new HttpPost("https://myInstance.service-now.com/api/now/table/incident");
String postData = " {\n" +

我得到一个错误响应输出如下： 我不确定创建事件中的必填字段是什么。 HTTP / 1.1 403禁止 {＆＃34;错误＆＃34;：{＆＃34;消息＆＃34;：＆＃34;操作失败＆＃34;，＆＃34;详细信息＆＃34;：＆＃34;插入事件期间出错（INC0009871） ）＆＃34;}＆＃34;状态＆＃34;：＆＃34;失效＆＃34;}
答案 0 :(得分：1)
403错误意味着您未将凭据传递到端点。您好像缺少身份验证标头
在第1行后尝试以下内容：
String encoding = Base64Encoder.encode ("<%your username%>:<%your password%>");
httpPost.setHeader("Authorization", "Basic " + encoding);
