推荐答案

Insert在回调函数的参数中提供了一个服务器响应。它提供了两个参数'error'和'result'，但是其中一个将总是null，这取决于插入是否成功。

Insert provides a server response in the arguments to a callback function. It provides two arguments 'error' and 'result' but one of them will always be null depending on whether the insert is successful.

Client.insert( { name: "xyz", userid: "1", care:"health" }
  , function( error, result) { 
    if ( error ) console.log ( error ); //info about what went wrong
    if ( result ) console.log ( result ); //the _id of new object if successful
  }
);
