Json Swift-HTTP POST中未正确发送编码密钥

Json Swift-HTTP POST中未正确发送编码密钥,json,swift,post,Json,Swift,Post,我正在我的应用程序中处理一个POST请求,该请求将向服务器发送有关照片的各种信息(注意:我不拥有该服务器)。为了得到一个成功的响应,我需要发送一个JSON对象,该对象包含以下键及其对应的照片值 { "description":"example", "media_url":"https://example.com", "attribute[request_type]":"Example", "service_code":"123456789", "lat":

我正在我的应用程序中处理一个POST请求,该请求将向服务器发送有关照片的各种信息(注意:我不拥有该服务器)。为了得到一个成功的响应,我需要发送一个JSON对象,该对象包含以下键及其对应的照片值

{
    "description":"example",
    "media_url":"https://example.com",
    "attribute[request_type]":"Example",
    "service_code":"123456789",
    "lat":"0.0",
    "api_key":"987654321",
    "long":"0.0"
}
在这个调用中,每个键名都需要精确匹配

我的问题在于属性[request\u type]键。由于某些原因,当我通过我的应用程序发送密钥时,它无法正确识别该密钥名。我知道这一点,因为它给了我以下的响应消息

    [{"code":400,"description":"Attribute request_type required"}]
我知道它所说的键名与JSON对象中的键名不同,但我使用Postman测试了属性[request_type]是正确的命名约定

我知道问题不在于我传递的值,否则它会告诉我属性请求类型无效

当我打印JSON对象时,所有字段都在那里

控制台的精确输出:

    {"description":"example","media_url":"https:\/\/example.com\/","attribute[request_type]":"example","service_code":"987654321","lat":"0.0","api_key":"123456789","long":"0.0"}
这就是我如何设置结构的方法

struct RequestModel: Codable {
    var api_key: String
    var service_code: String
    var description: String
    var media_url: String
    var requestType: String
    var long: String
    var lat: String

    enum CodingKeys: String, CodingKey {
        case requestType = "attribute[request_type]"

        case api_key
        case service_code
        case description
        case long
        case lat
        case media_url
    }

    init(api_key: String, service_code: String, lat: String, long: String, media_url: String, description: String, requestType: String) {
        self.api_key = api_key
        self.service_code = service_code
        self.description = description
        self.media_url = media_url
        self.long = long
        self.lat = lat
        self.requestType = requestType
    }
}
这就是函数本身

func send(lat: Double, long: Double, comment: String, photoURL: String) {
        let lattitude = String(lat)
        let longitute = String(long)
        let description = comment
        let mediaURL = photoURL

        //Prepping Data
        let sendReqeust = RequestModel(api_key: "123456789", service_code: "987654321", lat: lattitude, long: longitute, media_url: mediaURL, description: description, requestType: "example")

        guard let uploadData = try? JSONEncoder().encode(sendReqeust) else {
            return
        }
        print(String(data: uploadData, encoding: .utf8)!)

        //Configuring an Upload Request
        let url = URL(string: "http://example.com")!
        var request = URLRequest(url: url)
        request.httpMethod = "POST"
        request.setValue("application/json", forHTTPHeaderField: "Content-Type")

        //Creating and Starting an Upload Task
        let task = URLSession.shared.uploadTask(with: request, from: uploadData) { data, response, error in
            print("Response: \(response)")
            if let error = error {
                print ("error: \(error)")
                return
            }
            guard let response = response as? HTTPURLResponse,
                (200...299).contains(response.statusCode) else {
                    print(String(data: data!, encoding: .utf8)!)
                    print ("server error")
                    return
            }
            if let mimeType = response.mimeType,
                mimeType == "application/json",
                let data = data,
                let dataString = String(data: data, encoding: .utf8) {
                print ("got data: \(dataString)")
            }
        }
        task.resume()
    }

我没有正确设置编码键吗?我的编码方法有问题吗?

将requestType=“attribute[request\u type]”更改为requestType=“request\u type”

我在
Alamofire
令牌处理方面也有类似的问题,我用
String
concat解决了这个问题

试试这个:

request.addValue(“{\”请求\类型\“:\”示例\“}”,用于HttpHeaderField:“属性”)
编辑

如果确实需要将信息传递到请求正文中,请尝试如下解析:

{
    "description":"example",
    "media_url":"https://example.com",
    "attribute": {
        "request_type":"Example"
    },
    "service_code":"123456789",
    "lat":"0.0",
    "api_key":"987654321",
    "long":"0.0"
}
解决方案

我遵循了上面的建议,所以现在代码如下所示

    // in the struct requestType now looks like this
    var attribute: [String: String]
    // in the init within the function looks like this
    let sendReqeust = RequestModel(api_key: "987654321", service_code: "123456789", lat: lattitude, long: longitute, media_url: mediaURL, description: description, attribute: ["request_type":"example"])


嘿不清楚,它是否与
邮递员一起工作?如果是,请附上
cURL
snippet好吗?我们需要确保它不是服务器端错误。为了做到这一点,我们可以使用任何
REST
客户机工具。如何从
Postman
获取
cURL
snipper,您可以在这里找到@AlexD。我可以在《邮递员》中报告它确实有效,但是我不能在不暴露api_键的情况下给出旋度。谢谢!最后,这项工作做得很好,提交了一份包含必要代码更改的编辑,供大家将来参考
