我想通過一個WEB API公開這個功能。它是建立在這段代碼的方式是,有人確實在URL中的GET的形式與它一起提供的查詢字符串:貓鼬查詢子文檔屬性
?field=value&anotherfield.subproperty=value
但我似乎無法得到基於子查詢文件屬性工作。下面你會發現我的準系統代碼,記錄我試圖收到和我的兩個測試用例。
代碼:
var express = require('express');
var router = express.Router();
var mongoose = require('mongoose');
var config = require('../config');
var User = require('../models/user');
var functions = require('../functions');
router.get('/', function(req,res,next) {
//Check Permissions associated with UID *TODO
var parameters = req.query;
console.log(parameters);
User.find(parameters, function(err, users) {
if (err)
{
json = functions.generateOperationOutcome("exception","error",err,"exception");
res.status(500);
res.json(json);
}
else
{
//Check for blank result
if (users.length === 0)
{
json = functions.generateOperationOutcome("not-found","warning","Non-Existent Resource","warning");
res.status(404);
res.json(json);
}
else {
res.status(200);
res.json(users);
}
}
});
});
實錄:

]
}
成功的查詢:
GET http://{{LOCAL}}/api/user?resourceType=testResource
返回從MongoDB的這一個模型。
不成功的查詢(不匹配查詢文檔中發現的):
GET http://{{LOCAL}}/api/user?telecom.system=phone
沒有返回模型回來,結果在404
謝謝你的回答。你能詳細說明我們如何利用像我們這樣的數組的查詢嗎?我們目前正在利用DocumentDB和MongoDB支持,所以我們希望有MongoDB/MongoDB方法來完成這項工作。 – Kyle
在純MongoDB中,您可以像[this]一樣執行此操作(https://docs.mongodb.com/manual/tutorial/query-documents/#match-a-field-without-specifying-array-index) –
