用字符串发送后请求

Question

我还没有能够发送一个迅速的post-request到一个接受字符串的服务器。服务器不接受JSON数据。苹果库中是否有任何方法？我找不到任何。

或者你甚至可以告诉我怎么写这样的方法？

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)") 

任何帮助表示赞赏！

如果服务器不接受JSON那么什么是设置页眉内容类型应用程序/ JSON的目的。您有两个选项，可以将内容作为json发送，也可以作为表单提交发送发布请求。我会告诉你两种可能的方式，

第一个只是张贴表单参数到url，它不接受json而是接受url编码的表单参数。

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，如果你的服务器接受json参数，那么这个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)") 
})

您可能会更好地使用Alamofire与Swift进行HTTP网络连接。
