Question

我对用于将参数发布到php webservice的代码有点困惑。此代码是创建帖子连接还是仅使用get连接。因为url的最大字符限制（2048个最大字符）我必须使用iphone app和php文件之间的post连接。此代码是否适用于长数据，如两个位置之间的所有纬度和经度（稍后将需要在服务器上发送）。我搜索了很多，但我仍然感到困惑。请帮帮我。代码：

let request = NSMutableURLRequest(URL: NSURL(string: CommonUtils.webservice_path)!)
    let session = NSURLSession.sharedSession()
    request.HTTPMethod = "POST"

    let postString = "type=updateUserDetail&Fname=" + fName + "&Lname=" + lName + "&mobile=" + mobileNo + "&phoneCode=" + countryCode + "&user_id=" + iUserId_str!
    request.HTTPBody = postString.dataUsingEncoding(NSUTF8StringEncoding)

    let task = session.dataTaskWithRequest(request, completionHandler: {data, response, error -> Void in
        if(data==nil){

        }else{

        }
    })

是的，代码创建了一个post方法

我使用的代码在

之下

SWIFT 2.0

    let post:NSString = "Pram1=\(ratingUp)"

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

            let url:NSURL = NSURL(string:"http://yoururltopost.com")! //change it to your url

            let postData:NSData = post.dataUsingEncoding(NSASCIIStringEncoding)! //data is being encoded

            let postLength:NSString = String( postData.length )

            let request:NSMutableURLRequest = NSMutableURLRequest(URL: url)
            request.HTTPMethod = "POST" //setting method as post
            request.HTTPBody = postData
            request.setValue(postLength as String, forHTTPHeaderField: "Content-Length")
            request.setValue("application/x-www-form-urlencoded", forHTTPHeaderField: "Content-Type")
            request.setValue("application/json", forHTTPHeaderField: "Accept") //set type of api
           // request.setValue(apiKey, forHTTPHeaderField: "Authorization") // use if you are use Authorization



            let session = NSURLSession.sharedSession()

            let task = session.dataTaskWithRequest(request){

                (data, response, error) -> Void in



                if (error == nil && data != nil)

                {

                    func parseJson()

                    {

                       // do whatever you want to do


                        }else{
// show error
                            let alertView:UIAlertView = UIAlertView()
                            alertView.title = "Rating Error"
                            alertView.message = "Please try after some time"
                            alertView.delegate = self
                            alertView.addButtonWithTitle("OK")
                            alertView.show()

                        }


                    }



                    dispatch_async(dispatch_get_main_queue(), parseJson)

                }
            }

            task.resume()

POST方法有2种方式，取决于API，一种是单个URL，你的请求体是一个字典（例如＆＃34; type＆＃34;：＆＃34; updateUserDetail＆＃34;， ..），第二个是将您的postString附加到带有空体的URL，您所做的是将假设附加到请求正文的URL的字符串放置并且可能无法正常工作

从swift2 IOS到PHP的POST连接
