Question

我想将以下卷曲请求操作为swift（或objective-c）。

curl -X POST \ -d "login_id=mylogin_id" \ 
-d "api_key=myapi_key" \ 
https://~~~~~/v2/authenticate/api

以下是我写的内容。

func authentication(){
    var loginID = "mylogin_id"
    var apiKey = "myapi_key"
    var post:NSString = "login_id=\(loginID)&api_key=\(apiKey)"

    NSLog("PostData: %@",post);

    var url:NSURL = NSURL(string:"https://~~~~~/v2/authenticate/api")!

    var postData:NSData = post.dataUsingEncoding(NSASCIIStringEncoding)!

    var postLength:NSString = String( postData.length )

    var request:NSMutableURLRequest = NSMutableURLRequest(URL: url)
    request.HTTPMethod = "POST"
    request.HTTPBody = postData
    request.setValue(postLength, forHTTPHeaderField: "Content-Length")
    request.setValue("application/x-www-form-urlencoded", forHTTPHeaderField: "Content-Type")
    request.setValue("application/json", forHTTPHeaderField: "Accept")


    var reponseError: NSError?
    var response: NSURLResponse?

    var urlData: NSData? = NSURLConnection.sendSynchronousRequest(request, returningResponse:&response, error:&reponseError)
}

如果登录成功，将返回一个令牌，但是，我无法得到它。

{"auth_token": "ea6d13c7bc50feb46cf978d137bc01a2"}

我提到this link。谢谢你的好意。

我已经重写了＃34; var request ~~＆＃34;如下所示，然后得到＆＃34;错误＆＃34;，因此看起来这段代码将urlData返回为nil。

如果您将找到解决问题的方法，请帮助我。

var request:NSMutableURLRequest = NSMutableURLRequest(URL: url)
    request.HTTPMethod = "POST"
    request.HTTPBody = postData
    //request.setValue(postLength, forHTTPHeaderField: "Content-Length")
    request.setValue("application/x-www-form-urlencoded", forHTTPHeaderField: "Content-Type")
    //request.setValue("application/json", forHTTPHeaderField: "Accept")

    var reponseError: NSError?
    var response: NSURLResponse?
    var urlData: NSData? = NSURLConnection.sendSynchronousRequest(request, returningResponse:&response, error:&reponseError)
    if (urlData != nil){
        var responseData:NSString  = NSString(data:urlData!, encoding:NSUTF8StringEncoding)!
        let res = response as NSHTTPURLResponse!;

        NSLog("Response code: %ld", res.statusCode);

        if (res.statusCode >= 200 && res.statusCode < 300){
            var responseData:NSString  = NSString(data:urlData!, encoding:NSUTF8StringEncoding)!

            NSLog("Response ==> %@", responseData);
        }
    }else{
        NSLog("Error");
    }

我代表NSURLConnection使用NSURLSession获得了身份验证令牌，但我仍然不确定为什么可以使用NSURLSession并且无法使用NSURLConnection。如果您有任何想法，请告诉我。谢谢你的好意。

func authentication2(){
    let request = NSMutableURLRequest(URL: NSURL(string: "https://~~~/v2/authenticate/api")!)
    request.HTTPMethod = "POST"

    var loginID = "mylogin_id"
    var apiKey = "myapi_key"
    var postString:NSString = "login_id=\(loginID)&api_key=\(apiKey)"

    request.HTTPBody = postString.dataUsingEncoding(NSUTF8StringEncoding)
    let task = NSURLSession.sharedSession().dataTaskWithRequest(request) {
        data, response, error in

        if error != nil {
            println("error=\(error)")
            return
        }

        println("response = \(response)")

        let responseString = NSString(data: data, encoding: NSUTF8StringEncoding)
        println("responseString = \(responseString)")
    }
    task.resume()
}

Swift（或objective-c）相当于curl请求
