Swift 使用JSON参数创建POST请求

如何创建POST请求，如下所示：

键=参数

值={“api_键”：“abc123”}

例如：POST:params=value

let resourceURL = "https://127.0.0.1"
let apiKey:String = "abc123"

let params = ["api_key": apiKey] as Dictionary<String, String>
    do {
        let jsonParams = try JSONSerialization.data(withJSONObject: params, options: .sortedKeys)
    
    } catch {
        print("Error in JSON.")
    }

var request = URLRequest(url: URL(string: resourceURL)!)
let headers = ["Content-Type": "application/x-www-form-urlencoded"]
                
request.httpMethod = "POST"
request.allHTTPHeaderFields = headers

让resourceURL=”https://127.0.0.1"
让apiKey:String=“abc123”
让params=[“api_key”：apiKey]作为字典
做{
让jsonParams=try JSONSerialization.data（使用jsonObject:params，选项：.sortedKeys）
}抓住{
打印（“JSON中的错误”）
}
var request=URLRequest（url:url（string:resourceURL）！）
let headers=[“内容类型”：“application/x-www-form-urlencoded”]
request.httpMethod=“POST”
request.allHTTPHeaderFields=标题

邮递员的请求示例：

要让x-www-form-urlencoded body尝试以下方法：

var comps = URLComponents()
comps.queryItems = [URLQueryItem(name: "params", value: "{\"api_key\": \"abc123\"}")]
request.httpBody = comps.query?.data(using: .utf8)

我想将其作为KEY=params发送，我做了编辑。
