Question

这是我启动http请求的方式：

let config = NSURLSessionConfiguration.defaultSessionConfiguration()
config.HTTPAdditionalHeaders = ["Accept": "application/json",
                                "Content-Type": "application/json",
                                "User-Agent": UIDevice.currentDevice().model]

let session = NSURLSession(configuration: config)

var request = NSMutableURLRequest(URL: NSURL(string: "http://WWWW/login/check"))
request.HTTPMethod = "POST"

let valuesToSend = ["email": self.email!, "password": self.password!]
var error: NSError?

let data = NSJSONSerialization.dataWithJSONObject(valuesToSend, options:NSJSONWritingOptions.PrettyPrinted, error: &error)
var err: NSErrorPointer?
if error == nil {

    let task = session.uploadTaskWithRequest(request, fromData: data, completionHandler: {data, response, error in

        if error == nil {
            println("DATA == \(NSString(data: data, encoding: NSUTF8StringEncoding))")
            println("response == \(response)")
        }

    })
    task.resume()

} else {
    println("Oups error \(error)")
}

在我的php文件中，我有

public function check()
    {
        if($this->input->post('email')) {
            echo json_encode("YES");
        } else {
            echo json_encode("NO");
        }
    }

它总是让我“不”。有人知道为什么吗？

Answer 1

<强>您好。解决。

这取决于您发送数据的方式。在我的情况下，它是原始的，只说请求正文。

所以你需要做一些事情：

$data = json_decode(file_get_contents('php://input'));

，数据将是包含帖子值的数组。

尝试使用：

func JSONParseArray(jsonString: String) -> Array<String> {
    var e: NSError?
    var data: NSData!=jsonString.dataUsingEncoding(NSUTF8StringEncoding)
    var jsonObj = NSJSONSerialization.JSONObjectWithData(
        data,
        options: NSJSONReadingOptions(0),
        error: &e) as Array<String>
    if e == 0 {
        return Array<String>()
    } else {
        return jsonObj
    }
}

    var bodyData = "email=" + email + "&password=" + password //Post data


    let URL: NSURL = NSURL(string: "URL to php file")
    let request:NSMutableURLRequest = NSMutableURLRequest(URL:URL)
    request.HTTPMethod = "POST"
    request.HTTPBody = bodyData.dataUsingEncoding(NSUTF8StringEncoding);
    NSURLConnection.sendAsynchronousRequest(request, queue: NSOperationQueue.mainQueue())
        {
            (response, data, error) in
            var output = NSString(data: data, encoding: NSUTF8StringEncoding) //Get the output
            var array = self.JSONParseArray(self.output) //The output but in a array
    }

在你的php文件中尝试使用：$_POST['email']

而非$ this-＆gt; input-＆gt; post（'email'）

NSURLSession iOS CodeIgniter不发送POST
