iOS curl -X POST 集成在 swift 中

Question

您好，我想将 Curl POST api 集成到我的代码中，我对此没有任何想法，请指导我如何用 swift 语言集成它

下面的网络服务调用我已经集成到我的代码中，已经尝试过但没有得到结果

curl -X POST http://stf.rortechnologies.com/api/session.js --data '{"user": {"email":"XXXXXX", "password":"XXXXXX"}}' -H "Content-Type:application/json"

    let parameters = ["email":"admin.test@stf.com", "password":"password"]

    let header = ["user": parameters]
    //create the url with URL
    let url = URL(string: "http://stf.rortechnologies.com/api/session.js")! //change the url

    //create the session object
    let session = URLSession.shared

    //now create the URLRequest object using the url object
    var request = URLRequest(url: url)
    request.httpMethod = "POST" //set http method as POST

    do {
        request.httpBody = try JSONSerialization.data(withJSONObject: header, options: .prettyPrinted) // pass dictionary to nsdata object and set it as request body
    } catch let error {
        print(error.localizedDescription)
    }

    request.addValue("application/json", forHTTPHeaderField: "Content-Type")
    request.addValue("application/json", forHTTPHeaderField: "Accept")

    //create dataTask using the session object to send data to the server
    let task = session.dataTask(with: request as URLRequest, completionHandler: { data, response, error in

        guard error == nil else {
            return
        }

        guard let data = data else {
            return
        }

        do {
            //create json object from data
            if let json = try JSONSerialization.jsonObject(with: data, options: .mutableContainers) as? [String: Any] {
                print(json)
                // handle json...
            }
        } catch let error {
            print(error.localizedDescription)
        }
    })
    task.resume()

这里得到空响应

应用传输安全 (ATS)

您正在调用 http url，而不是 https url。在生产中始终应使用 https。这是由 iOS 强制执行的。

出于测试目的，可以在 info.plist 中声明异常，可以在此处找到文档: https://developer.apple.com/library/archive/documentation/General/Reference/InfoPlistKeyReference/Articles/CocoaKeys.html#//apple_ref/doc/uid/TP40009251-SW33

JSON 编码/解码

在 Swift 中，有一种使用 JSONEncode/JSONDecoder 来编码/解码 JSON 的便捷方法。一个简单的解决方案可能如下所示。

定义参数结构

struct Login: Encodable {
    let user: User
}

struct User: Encodable {
    let email: String
    let password: String
}

定义返回结构

struct Result: Decodable {
    //add expected JSON fields here
}

休息通话

private func makeRestCall() {

    let login = Login(user: User(email: "admin.test@stf.com", password: "password"))
    guard let loginJson = try? JSONEncoder().encode(login) else { return }

    let config = URLSessionConfiguration.default
    let session = URLSession(configuration: config)

    guard let url = URL(string: "<add some valid url here>") else { return }
    var request = URLRequest(url: url)
    request.httpMethod = "POST"
    request.addValue("application/json", forHTTPHeaderField: "Accept")
    request.addValue("application/json", forHTTPHeaderField: "Content-Type")
    request.httpBody = loginJson

    let dataTask = session.dataTask(with: request) { (data, response, error) in

        if let response = response as? HTTPURLResponse {
            if response.statusCode == 200 {
                guard let data = data else {
                    print ("call failed - no data returned")
                    return
                }
                guard let result = try? JSONDecoder().decode(Result.self, from: data) else {
                    print ("json decoding failed")
                    return
                }
                print ("call succesfully returned \(result)")
            } else {
                print ("call failed with status \(response.statusCode)")
            }
        } else {
            print ("call failed: no http response")
        }
    }

    dataTask.resume()

}

checkin HTTPS 代理

为了确保发送正确的数据，您可以使用 HTTPS 代理软件。它看起来像这样:
