将多个数据附加到 URLRequest 的 httpbody

Question

我想将另一个字典作为参数附加到 URLRequest 的 httpBody

请求型号：

struct RequestModel: Encodable {

    let body: Body
}

struct Body: Encodable {
    let name: String
    let score: String
    let favList: [String]
}

Api 请求：

do {
            var urlRequest = URLRequest(url: resourceURL)
            urlRequest.httpMethod = kHTTPMethodPOST
            urlRequest.addValue("application/json", forHTTPHeaderField: "Content-Type")
            urlRequest.httpBody = try JSONEncoder().encode(self.requestModel)

            let dataTask = URLSession.shared.dataTask(with: urlRequest) { data, response, error in

                guard let httpResponse = response as? HTTPURLResponse,
                    httpResponse.statusCode == 200,
                    let jsonData = data else {
                        completion(.failure(.responseError))
                        return
                }


            }
            dataTask.resume()

        } catch {
         completion(.failure(.unknownError))
        }

另一个字典：airports

var airports: [String: String] = ["YYZ": "Toronto Pearson", "DUB": "Dublin"]

尝试将 airports 字典参数附加到 URLRequest 但无法附加。

感谢您的帮助和建议！

谢谢

Answer 1

POST JSON 的常用语法是

do { 
    var urlRequest = URLRequest(url: resourceURL)
    urlRequest.httpMethod = "POST"
    let postData = try JSONEncoder().encode(self.requestModel)
    urlRequest.httpBody = postData
    urlRequest.setValue("\(postData.count)", forHTTPHeaderField:"Content-Length")
    urlRequest.setValue("application/json", forHTTPHeaderField:"Accept")
    urlRequest.setValue("application/json", forHTTPHeaderField:"Content-Type")

}

Answer 2

如果您必须将 airports 字典附加到请求正文，您可能希望将其包含在请求模型本身中。

我建议更新您的 RequestModel 并使其成为 Encodable。

并将您的 airports 口述作为 RequestModel

的一部分

像这样

struct RequestModel: Encodable {

    let body: Body
    let airportsDict: [String:String]
}

struct Body: Encodable {
    let name: String
    let score: String
    let favList: [String]
}

这样您的 httpBody 将拥有您要传递的所有数据。
