swift - 无法使用 Swift 发出 Post 请求

Question

我尝试用 swift 发出 post 请求，但它总是显示错误。我只是复制我的 chrome 所做的发布请求(通过开发人员工具)。

func postRequest(){

    let request = NSMutableURLRequest(URL: NSURL(string: "http://blich.iscool.co.il/tabid/2117/language/he-IL/Default.aspx/")!)
    request.HTTPMethod = "POST"
    let postString = "__VIEWSTATE=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&nn$ctr7919$TimeTableView$ClassesList=1&dnn$ctr7919$TimeTableView$MainControl$WeekShift=0&dnn$ctr7919$TimeTableView$ControlId=8"
    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()



        }

结果是:

response = <NSHTTPURLResponse: 0x7ffc90f054a0> { URL: http://blich.iscool.co.il/Default.aspx?tabid=2117&error=The+state+information+is+invalid+for+this+page+and+might+be+corrupted.&content=0 } { status code: 200, headers {

当我在没有发出 post 请求的情况下读取文件时，它会显示正确的内容，但是当我发出 post 请求时，它会显示错误。

我该如何解决这个问题？我希望该网站向我显示我在应用程序中选择的右侧表格中的数据。 http://blich.iscool.co.il/tabid/2117/language/he-IL/Default.aspx/

这是当前代码:错误已修复 - 但仍然不执行任何操作

Answer 1

尝试使用这个SRWebClient 。您只需添加 this swift file添加到您的项目并将其另存为 SRWebClient.swift。

然后，当您发帖时，您可以使用此代码。

 SRWebClient.POST("http://blich.iscool.co.il/tabid/2117/language/he-IL/Default.aspx/")
                .data(["yourFieldName":"yourValueForTheField"])
                .send({(response:AnyObject!, status:Int) -> Void in
                       //this is success part
                        println(response)
                    }, failure:{(error:NSError!) -> Void in
                       //this is failure part 
                        println(error)
                    })

这是最简单、最容易的方法。尝试一下，如果有任何问题，请告诉我。谢谢。
