如何添加Alamofire URL参数 [英] How to add Alamofire URL parameters

问题描述

我有一个使用邮递员传递URL参数的工作方案。现在，当我尝试在Swift中通过Alamofire进行操作时，它将无法正常工作。

I have a working scenario using Postman passing in URL parameters. Now when I try to do it via Alamofire in Swift, it does not work.

如何在Alamofire中创建此网址？
http：// localhost：8080 /？test = 123

How would you create this url in Alamofire? http://localhost:8080/?test=123

    _url = "http://localhost:8080/"
    let parameters: Parameters = [
        "test": "123"
        ]

    Alamofire.request(_url,
                      method: .post,
                      parameters: parameters,
                      encoding: URLEncoding.default,
                      headers: headers

推荐答案

问题是使用 URLEncoding.default 。Alamofire根据HTTP 方法对 URLEncoding.default 的解释不同。

The problem is that you're using URLEncoding.default. Alamofire interprets URLEncoding.default differently depending on the HTTP method you're using.

对于 GET ， HEAD

For GET, HEAD, and DELETE requests, URLEncoding.default encodes the parameters as a query string and adds it to the URL, but for any other method (such as POST) the parameters get encoded as a query string and sent as the body of the HTTP request.

为了在 POST 请求，您需要将 encoding 参数更改为 URLEncoding（destination：.queryString）。

In order to use a query string in a POST request, you need to change your encoding argument to URLEncoding(destination: .queryString).

您可以在此处查看有关Alamofire如何处理请求参数的更多详细信息。 。

您的代码应如下所示：

   _url = "http://localhost:8080/"
    let parameters: Parameters = [
        "test": "123"
        ]

    Alamofire.request(_url,
                      method: .post,
                      parameters: parameters,
                      encoding: URLEncoding(destination: .queryString),
                      headers: headers)
