我正在尝试通过Google Apps脚本运行MongoLab(基于REST的MongoDB访问)查询。从记录器生成的URL如下所示
https://api.mongolab.com/api/1/databases/abcd/collections/efgh?apiKey=XXXXXXXXXXXXXXXX&q= {“created_on”:{“$ gte”:“Thu Dec 06 00:00:00 PST 2012”,“$ lt”:“Thu Dec 06 23:59:59 PST 2012”}}
当我在浏览器中输入此内容时,它可以正常工作并获取我正在寻找的响应。但是通过UrlFetchApp运行它会产生“无效参数”错误。我看到有几个帖子在同一行,但没有找到适合我的答案。 Javascript代码如下
//start and end are JS date objects
var query = { created_on : {'$gte': start, '$lt' : end} };
var url = MONGO_LAB_URLS.MAIN + "&q=" + Utilities.jsonStringify(query);
Logger.log("Query URL : " + url);
var response = UrlFetchApp.fetch(url);
我尝试过encodeURIComponent,但它没有用 - 可能是我做错了。有关如何克服这个问题的任何建议吗? 感谢。

无效参数即将发生,因为您在URL参数中发送了无效字符。您应该首先对参数进行编码。
我修改了你的代码并尝试运行。但由于invaliD API密钥很明显,它仍然失败了。您可以使用有效的API密钥尝试此代码。
//start and end are JS date objects
MONGO_LAB_URLS = 'https://api.mongolab.com/api/1/databases/abcd/collections/efgh?apiKey=XXXXXXXXXXXXXXXX&q=';
var start = 'Thu Dec 06 00:00:00 PST 2012';
var end = 'Thu Dec 06 23:59:59 PST 2012';
var query = { created_on : {'$gte': start, '$lt' : end} };
var url = MONGO_LAB_URLS + encodeURIComponent(Utilities.jsonStringify(query));
Logger.log("Query URL : " + url);
var response = UrlFetchApp.fetch(url);
Logger.log(response);
我得到的回应是
Request failed for https://api.mongolab.com/api/1/databases/abcd/collections/efgh?apiKey=XXXXXXXXXXXXXXXX&q=%7B%22created_on%22%3A%7B%22%24gte%22%3A%22Thu%20Dec%2006%2000%3A00%3A00%20PST%202012%22%2C%22%24lt%22%3A%22Thu%20Dec%2006%2023%3A59%3A59%20PST%202012%22%7D%7D returned code 400.
