Swift webview xcode发布数据

Question

我有一个webview，目前编码如下:

    let url = NSURL(string: "http://example.com")
    let request = NSURLRequest(URL: url!)
    monitorView.loadRequest(request)

这工作得很好，但是当涉及到向这个url发布数据然后加载它时，我该如何得到呢?我对swift还不太熟悉，似乎不太明白。

Answer 1

你可以使用像NSURLSession这样的类，它允许控制你的HTTP交互，并在你的webView中加载HTML字符串

使用例子:

let request = NSMutableURLRequest(URL: NSURL(string: "http://www.someLink.com/postName.php"))
request.HTTPMethod = "POST"
let postString = "id=XYZ"
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()

或者你可以准备一个带有POST主体的NSMutableURLRequest并像这样加载到你的webView中:

//need to use MutableRequest to set HTTPMethod to Post.
var url = NSURL(string: "http://www.somesite.com/post.php")
var request = NSMutableURLRequest(URL: url!)
request.HTTPMethod = "POST"
var bodyData: String = "someUsernameOrKey"
request.HTTPBody = bodyData.dataUsingEncoding(NSUTF8StringEncoding)
webView.loadRequest(request)

我真的很喜欢AFNetworking

得到

import AFNetworking
var urlBase = "www.example.com"
func getShopData(shopDataResponse:(Bool)-> Void )
{
        if let userid = @"exampleid"
        {
        let urlStr =  urlBase + "shops/get?u=" + (userid as! String)
        let manager = AFHTTPRequestOperationManager() 
        manager.GET(urlStr, parameters: nil, success: {(req : AFHTTPRequestOperation!, result : AnyObject!) in
            println("The Result (result)")
            if let resultActual: AnyObject = result
            {
              println(result)
              shopDataResponse(true);
            }
            , failure: {(req : AFHTTPRequestOperation!, error : NSError!) in
                println("fail with error (error.description)")
                shopDataResponse(false);
        })
    }
 }

func getName(id :String){
    let manager = AFHTTPRequestOperationManager()
    let urlStr = urlBase + "name"
    let userId = id
        manager.requestSerializer = AFJSONRequestSerializer()
        manager.POST(urlStr, parameters: parameters,
            success: {(req : AFHTTPRequestOperation!, result : AnyObject!) in
                println("JSON: (result)")
            }
            , failure: {(req : AFHTTPRequestOperation!, error : NSError!) in
                println("fail with error (error.description)")
        })
    }
}
