如何在Swift中使用JSON POST方法将字典值传递给键中的参数

Question

对于下面的API，必须传递标头和参数。

工作网址：http://itaag-env-1.ap-south-1.elasticbeanstalk.com/editprofile/

其标题：[“设备ID”：“ 584D97F-761A-4C24-8C4B-C145A8B8BD75”，“ userType”：“个人”，“密钥”：“ 9609cc826b0d472faf9967370c095c21”]

其参数：

profileImage和ContentType.MULTIPART_FORM_DATA：“多部分/表单数据”

profiledetails：“ {” firstName“：” Satish“，” lastName“：” Madhavarapu“，” gender“：” male“，” ageGroup“：” 40-50“}”]

像这样在POSTMAN中，我们得到输出：

POSTMAN image with parameters and response

这里是代码，这里如何添加profiledetails参数：

func getPostString(params:[String:Any]) -> String
{
    var data = [String]()
    for(key, value) in params
    {
        data.append(key + "=\(value)")
    }
    print(data.map { String($0) }.joined(separator: "&"))
    return data.map { String($0) }.joined(separator: "&")
}

func callPostApi(){
    let url = URL(string: "http://itaag-env-1.ap-south-1.elasticbeanstalk.com/editprofile/")
    guard let requestUrl = url else { fatalError() }
    var request = URLRequest(url: requestUrl)
    request.httpMethod = "POST"

    request.setValue("584D97F-761A-4C24-8C4B-C145A8B8BD75", forHTTPHeaderField: "deviceid")
    request.setValue("9609cc826b0d472faf9967370c095c21", forHTTPHeaderField: "key")
    request.setValue("personal", forHTTPHeaderField: "userType")

    let parameters = getPostString(params:   ["profileImage and ContentType.MULTIPART_FORM_DATA": "multipart/form-data", "profiledetails": "{"firstName":"Satish", "lastName":"Madhavarapu","gender":"male", "ageGroup":"40-50"}"])
    request.httpBody = parameters.data(using: .utf8)
    // Perform HTTP Request
    let task = URLSession.shared.dataTask(with: request) { (data, response, error) in
            let httpResponse = response as? HTTPURLResponse
            print(httpResponse!.statusCode)
            // Check for Error
            if let error = error {
                print("Error took place \(error)")
                return
            }

            // Convert HTTP Response Data to a String
            if let data = data, let dataString = String(data: data, encoding: .utf8) {
                print("Response data string:\n \(dataString)")
            }
    }
    task.resume()
}

如何添加参数：

let parameters = getPostString(params:   ["profileImage and ContentType.MULTIPART_FORM_DATA": "multipart/form-data", "profiledetails": "{"firstName":"Satish", "lastName":"Madhavarapu","gender":"male", "ageGroup":"40-50"}"])

如何添加参数字典值，请帮助我代码。

您需要使用字典数组，以便更改方法的定义
