在 swift 中使用 alamofire 将参数作为原始数据发送

Question

在 swift 中使用 alamofire 时，我将以下原始数据作为参数发送

{
    "customer": {
        "firstname": "test",
        "lastname": "user",
        "email": "testuser30@gmail.com",
        "website_id": 1,
        "addresses": [
        {
            "customer_id": 3292,
            "region": {
                "region": "New York"
            },
            "country_id": "US",
            "street": [
                "US"
            ],
            "telephone": "84656313",
            "postcode": "34521",
            "city": "us",
            "firstname": "test",
            "lastname": "usr",
            "default_shipping": true,
            "default_billing": true
        }
    ]

    }

}

我已经使用 alamofire 在代码中编写了如下给出的参数。

  let customer : Parameters = [
                    "email":email,
                    "firstname":fname,
                    "lastname":lname,
                    "website_id":1,
                    "addresses": {
                        [
                            "customer_id": id,
                            "region": [
                                "region": state
                            ],
                            "country_id": country,
                            "street": {
                                self.add1Txt.text! + self.add2Txt.text!
                            },
                            "telephone": self.phoneTxt.text!,
                            "postcode": self.pincodeTxt.text!,
                            "city": self.cityTxt.text!,
                            "firstname": self.fnameLbl.text!,
                            "lastname": self.lnameLbl.text!,
                            "default_shipping": true,
                            "default_billing": true
                        ]
                    }
                 ]

                let parameters: Parameters =
                               [
                                    "customer": customer

                               ]

它显示“JSON 写入 (__SwiftValue) 中的类型无效”。这个参数传递有什么问题？

您的客户变量不是正确的字典。 "addresses": { 实际上是一个字典数组。它应该类似于以下代码。除此之外，如果您使用 Codable 创建模型结构并借助 JSONEncoder 和 JSONSerialization 转换为字典，则可以避免此类问题。你可以看到这个thread。

 let parameters: Parameters = ["customer": [
            "addresses" : [[

                            "city": "us",
                            "country_id" :"US",
                            "customer_id" :"3292",
                            "default_billing" : 1,
                            "default_shipping" : 1,
                            "firstname" :"test",
                            "lastname" :"usr",
                            "postcode" :34521,
                            "region" : ["region" : "New York"],
                            "street" : ["US"],
                            "telephone" : 84656313

            ]],
            "email" : "testuser30@gmail.com",
            "firstname": "test",
            "lastname": "user",
            "website_id" : 1
        ]]

使用Quicktype 立即从您的 json 生成结构：

import Foundation

// MARK: - Parameters
struct Parameters: Codable {
    let customer: Customer?
}

// MARK: - Customer
struct Customer: Codable {
    let firstname, lastname, email: String?
    let websiteID: Int?
    let addresses: [Address]?

    enum CodingKeys: String, CodingKey {
        case firstname, lastname, email
        case websiteID = "website_id"
        case addresses
    }
}

// MARK: - Address
struct Address: Codable {
    let customerID: Int?
    let region: Region?
    let countryID: String?
    let street: [String]?
    let telephone, postcode, city, firstname: String?
    let lastname: String?
    let defaultShipping, defaultBilling: Bool?

    enum CodingKeys: String, CodingKey {
        case customerID = "customer_id"
        case region
        case countryID = "country_id"
        case street, telephone, postcode, city, firstname, lastname
        case defaultShipping = "default_shipping"
        case defaultBilling = "default_billing"
    }
}

// MARK: - Region
struct Region: Codable {
    let region: String?
}
