Question

我是swift的新手，我正在尝试使用Alamofire从json文件获取链接。我一直在谷歌搜索几天，并没有找到任何有用的解决方案。我对json数组不太好。我需要来自（_links.https：//api.w.org/featuredmedia.href）的链接这是我的代码：

guard let ide = self.json[0]["_links"]["https:\/\/api.w.org\/featuredmedia"]["href"].string else{
        print("Request failed with error")
        return
}
    print(ide)


    Alamofire.request(.GET, "http://tricitychurchofchrist.com/wp-json/wp/v2/ctc_sermon/5640").responseJSON { response in
            guard let _ = response.result.value else{
                print("Request failed with error")
                return
            }
    }

这是json：

我正在使用来自wordpress网站的json的WP REST API。

Answer 1

您返回的数据类型是对象类型，您应该将其更改为JSON对象，您可以在github上使用SwiftJSON开源，并且代码如下：

wp_render_posts

jsonDic现在是一个NSDictionary类型，将NSDictionary更改为NSArray，你可以直接使用它，希望有帮助

无法使用Alamofire从rest api中选择json数组
