推荐答案

您可以创建像这样的远程方法:

You could create a remote method like this:

User.unblock = function(id, userId, blockId, callback) {
  var result;
  // TODO
  callback(null, result);
};

然后，json文件中的远程方法定义如下所示:

Then, the remote method definition in the json file could look like this:

"unblock": {
  "accepts": [
    {
      "arg": "id",
      "type": "string",
      "required": true,
      "description": "",
      "http": {
        "source": "path"
      }
    },
    {
      "arg": "userId",
      "type": "string",
      "required": false,
      "description": "",
      "http": {
        "source": "form"
      }
    },
    {
      "arg": "blockId",
      "type": "string",
      "required": false,
      "description": "",
      "http": {
        "source": "form"
      }
    }
  ],
  "returns": [
    {
      "arg": "result",
      "type": "object",
      "root": false,
      "description": ""
    }
  ],
  "description": "",
  "http": [
    {
      "path": "/:id/unblock",
      "verb": "post"
    }
  ]
}

然后，您的远程方法将如下所示:

Then your remote method would look like this:

您可以使用函数参数，并使用一个body参数而不是2个form参数，并从那里读取数据，尽管我相信，如果只有2个其他参数，最好将它们分开放置.但这取决于您的方法.

You could play around with function arguments and use one body argument instead of 2 form arguments and read the data from there, although I believe that if there are only 2 additional parameters it's better to put them separately. But it depends on your approach.
