ios - 带有身份验证的 API Swift 4 调用。简单的。但卡住了

Question

找到一个简单的答案让我终于问了。

我需要做什么/添加什么来发送带有 url 调用的身份验证？我全力以赴，但就是看不到解决方案。

使用必要的信息设置 url，然后调用电话。这是 Curl 调用:

curl -v -X GET https://api.jsecoin.com/v1.7/balance/auth/0/ \
     -H "Content-Type: application/json" \
     -H "Authorization: JSE API Key"

示例响应:

{
 "success": 1, 
 "notification": "Your balance is 99 JSE",
 "balance": 99
 }

这是我在 Swift 4、XCode 9.xx iOS 11.4 中执行此操作的代码片段，但我不知道如何添加授权。

 func makeGetCall() {
    // Set up the URL request
    //let todoEndpoint: String = "https://jsonplaceholder.typicode.com/todos/1"


    let todoEndpoint: String = "https://api.jsecoin.com/v1.7/balance/auth/0/"

    //-H \"Content-Type: application/json\" -H \"Authorization: xxxxxxxxxxxxxxxxx\""

    guard let url = URL(string: todoEndpoint) else {
        print("Error: cannot create URL")
        return
    }
    let urlRequest = URLRequest(url: url)

    // set up the session
    let config = URLSessionConfiguration.default
    let session = URLSession(configuration: config)

    config.httpAdditionalHeaders = [
        "Content-Type": "application/json",
        "Authorization": "xxxxxxxxxxxxxxxxxxxxx"
    ]

    // make the request
    let task = session.dataTask(with: urlRequest) {
        (data, response, error) in
        // check for any errors
        guard error == nil else {
            print("error calling GET on /todos/1")
            print(error!)
            return
        }

返回，

The todo is: ["notification": API Balance Failed: User API key credentials  could not be matched, "fail": 1]

无法从 JSON 获取待办事项标题

您需要在 URLRequest 中设置 Header 参数，而不是在 URLSessionConfiguration 中

这是你的解决方案

func makeGetCall() {
    // Set up the URL request
    //let todoEndpoint: String = "https://jsonplaceholder.typicode.com/todos/1"


    let todoEndpoint: String = "https://api.jsecoin.com/v1.7/balance/auth/0/"

    //-H \"Content-Type: application/json\" -H \"Authorization: xxxxxxxxxxxxxxxxx\""

    guard let url = URL(string: todoEndpoint) else {
        print("Error: cannot create URL")
        return
    }
    let urlRequest = URLRequest(url: url)


    urlRequest.setValue(signature, forHTTPHeaderField: "Authorization")
    urlRequest.setValue("application/json", forHTTPHeaderField: "Content-Type")
    // set up the session
    let config = URLSessionConfiguration.default
    let session = URLSession(configuration: config)



    // make the request
    let task = session.dataTask(with: urlRequest) {
        (data, response, error) in
        // check for any errors
        guard error == nil else {
            print("error calling GET on /todos/1")
            print(error!)
            return
        }
