如何将所有 phone 联系人传递给 swift 中的 JSON API

Question

我能够在 table 视图中获取所有 phone 联系人。

我需要在名为 contactsList 的 JSON URL 参数中传递所有 phone 联系人，但我无法将所有 phone 联系人传递给 Json参数contactsList

如果我像下面的代码一样发送个人 phone 号码，它就来了

但我需要将我所有的 phone 联系人发送到 JSON API

代码：这里 api 和给定的 phone 数字都在工作..这里用我的代码你也可以检查 JSON 响应..但是我需要将所有 phone 联系人发送到 API

import UIKit
import Contacts
class ContactsViewController: UIViewController,UITableViewDelegate,UITableViewDataSource {

@IBOutlet weak var joinersTableView: UITableView!
var contacts = [CNContact]()
var phNumArray  = ["5555555544", "1212121212"]
var taggedStatus: String?

override func viewDidLoad() {
    super.viewDidLoad()
    joinersTableView.register(UINib(nibName: "ContactsTableViewCell", bundle: nil), forCellReuseIdentifier: "ContactsTableViewCell")
    ContactsModel.shared.getLocalContacts {(contact) in
        self.contacts.append(contact!)
    }
    joinersTableView.reloadData()

    self.callPostApi()
}

func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
    return contacts.count
}
func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
    
    let cell: ContactsTableViewCell = tableView.dequeueReusableCell(withIdentifier: "ContactsTableViewCell") as! ContactsTableViewCell
    cell.nameLbl.text    = contacts[indexPath.row].givenName + " " + contacts[indexPath.row].familyName
    cell.phNUmLbl.text = contacts[indexPath.row].phoneNumbers.first?.value.stringValue
   
    return cell
    
}

    func callPostApi() {

        let url            = URL(string: "http://itaag-env-1.ap-south-1.elasticbeanstalk.com/filter/taggedusers/")!
        var request        = URLRequest(url: url)
        request.httpMethod = "POST"

        request.setValue("F139424D-C749-42F6-B804-21BD17E28CE0", forHTTPHeaderField: "deviceid")
        request.setValue("c913136e897b419bab20746de7baab62", forHTTPHeaderField: "key")
        request.setValue("personal", forHTTPHeaderField: "userType")

        try? request.setMultipartFormData(["contactsList": "\(phNumArray)"], encoding: .utf8)
       
        URLSession.shared.dataTask(with: request) { data, _, _ in
            if let data = data, let jsonObj = try? JSONSerialization.jsonObject(with: data, options: .mutableContainers) as? [String: Any] {
           print("contacts JSON \(jsonObj)")
                let phnDict = jsonObj as? [String : Any]
                
                print("each phone number1111111 \(phnDict)")

            }
        }.resume()
    }
    }
 extension URLRequest {

public mutating func setMultipartFormData(_ parameters: [String: String], encoding: String.Encoding) throws {

    let makeRandom = { UInt32.random(in: (.min)...(.max)) }
    let boundary = String(format: "------------------------%08X%08X", makeRandom(), makeRandom())

    let contentType: String = try {
        guard let charset = CFStringConvertEncodingToIANACharSetName(CFStringConvertNSStringEncodingToEncoding(encoding.rawValue)) else {
            throw MultipartFormDataEncodingError.characterSetName
        }
        return "multipart/form-data; charset=\(charset); boundary=\(boundary)"
    }()
    addValue(contentType, forHTTPHeaderField: "Content-Type")

    httpBody = try {
        var body = Data()

        for (rawName, rawValue) in parameters {
            if !body.isEmpty {
                body.append("\r\n".data(using: .utf8)!)
            }

            body.append("--\(boundary)\r\n".data(using: .utf8)!)

            guard
                rawName.canBeConverted(to: encoding),
                let disposition = "Content-Disposition: form-data; name=\"\(rawName)\"\r\n".data(using: encoding) else {
                throw MultipartFormDataEncodingError.name(rawName)
            }
            body.append(disposition)

            body.append("\r\n".data(using: .utf8)!)

            guard let value = rawValue.data(using: encoding) else {
                throw MultipartFormDataEncodingError.value(rawValue, name: rawName)
            }

            body.append(value)
        }

        body.append("\r\n--\(boundary)--\r\n".data(using: .utf8)!)

        return body
    }()
}
}

public enum MultipartFormDataEncodingError: Error {
case characterSetName
case name(String)
case value(String, name: String)
}

编辑：输出：这里我如何获得每个联系人 userName 和 tagged 值

contacts JSON ["(408) 555-5270": {
oniTaag = 0;
profilePic = "<null>";
tagged = 0;
userId = "<null>";
userName = "<null>";
userType = personal;
}, "555-522-8243": {
oniTaag = 0;
profilePic = "<null>";
tagged = 0;
userId = "<null>";
userName = "<null>";
userType = personal;
}, "(408) 555-3514": {
oniTaag = 0;
profilePic = "<null>";
tagged = 0;
userId = "<null>";
userName = "<null>";
userType = personal;
}, "555-478-7672": {
oniTaag = 0;
profilePic = "<null>";
tagged = 0;
userId = "<null>";
userName = "<null>";
userType = personal;
.......

要将联系人数组转换为字符串数组，您可以这样做

let phNumArray = contacts.flatMap { [=10=].phoneNumbers }.map { [=10=].value.stringValue }

然后你就可以像现在这样发送phNumArray了。

在评论中回答问题。
对于联系的其他属性，你可以这样做

for contact in contacts {
    print(contact.givenName)
    print(contact.familyName)
}

显然，在这种情况下，您需要使用正确的密钥 CNContactGivenNameKey、CNContactFamilyNameKey 在联系人获取期间。
