用字符串發送後請求

Question

我還沒有能夠發送一個迅速的post-request到一個接受字符串的服務器。服務器不接受JSON數據。蘋果庫中是否有任何方法？我找不到任何。

或者你甚至可以告訴我怎麼寫這樣的方法？

let url = NSURL(string: "myUrl") 
var session = NSURLSession.sharedSession() 
let request = NSMutableURLRequest(URL: url) 
    request.HTTPMethod = "POST" 
var params = "login_act:'myUsername'&login_pwd:'myPassword'" 

var err: NSError? 
request.HTTPBody = NSJSONReadingOptions. 
// The following method call does not accept the params variable type, although I need to send a String 
request.HTTPBody = NSJSONSerialization.dataWithJSONObject(params, options: nil, error: &err) 
request.addValue("application/json", forHTTPHeaderField: "Content-Type") 
request.addValue("application/json", forHTTPHeaderField: "Accept") 

var task = session.dataTaskWithRequest(request, completionHandler: {data, response, error -> Void in 
    println("Response: \(response)") 
    var strData = NSString(data: data, encoding: NSUTF8StringEncoding) 
    println("Body: \(strData)") 

任何幫助表示讚賞！

如果服務器不接受JSON那麼什麼是設置頁眉內容類型應用程序/ JSON的目的。您有兩個選項，可以將內容作爲json發送，也可以作爲表單提交發送發佈請求。我會告訴你兩種可能的方式，

第一個只是張貼表單參數到url，它不接受json而是接受url編碼的表單參數。

let url = NSURL(string: "myUrl") 
var session = NSURLSession.sharedSession() 
let request = NSMutableURLRequest(URL: url) 
    request.HTTPMethod = "POST" 
var params = "login_act=myUsername&login_pwd=myPassword" 
request.HTTPBody = params.dataUsingEncoding(NSUTF8StringEncoding, allowLossyConversion: false) 
var err: NSError? 

request.addValue("application/x-www-form-urlencoded", forHTTPHeaderField: "Content-Type") 

var task = session.dataTaskWithRequest(request, completionHandler: {data, response, error -> Void in 
    println("Response: \(response)") 
    var strData = NSString(data: data, encoding: NSUTF8StringEncoding) 
    println("Body: \(strData)") 
}) 

其他方法，如果你的服務器接受json參數，那麼這個方法和你所做的很相似。

let url = NSURL(string: "myUrl") 
var session = NSURLSession.sharedSession() 
let request = NSMutableURLRequest(URL: url) 
    request.HTTPMethod = "POST" 
var params = ["login_act":"myUsername", "login_pwd":"myPassword"] 

var err: NSError? 
// The following method call does not accept the params variable type, although I need to send a String 
request.HTTPBody = NSJSONSerialization.dataWithJSONObject(params, options: nil, error: &err) 
request.addValue("application/json", forHTTPHeaderField: "Content-Type") 
request.addValue("application/json", forHTTPHeaderField: "Accept") 

var task = session.dataTaskWithRequest(request, completionHandler: {data, response, error -> Void in 
    println("Response: \(response)") 
    var strData = NSString(data: data, encoding: NSUTF8StringEncoding) 
    println("Body: \(strData)") 
})

您可能會更好地使用Alamofire與Swift進行HTTP網絡連接。
