swift开发网络篇 - post 请求

/**

所有网络请求,统一使用异步请求!

在今后的开发中,如果使用简单的get/head请求,可以用NSURLConnction异步方法

GET查/POST增/PUT改/DELETE删/HEAD

GET

1> URL

2> NSURLRequest

3> NSURLConnction 异步

POST

1> URL

2> NSMutableURLRequest

.httpMethod = @"POST";

str 从 firebug直接粘贴,或者自己写

变量名1=数值1&变量名2=数值2

.httpData = [str dataUsingEncoding:NSUTF8StringEncoding];

3> NSURLConnction 异步

overridefunc viewDidLoad() {

super.viewDidLoad()

self.postLogon()

}

func postLogon(){

var path ="http://xxxxxxxx.com"

var params:NSMutableDictionary = NSMutableDictionary()

params["mobile_phone"] ="1xxxxxxxxx5"

params["password"] ="123456"

var headparams:NSMutableDictionary = NSMutableDictionary()

headparams["X-xxxx-App-Token"] = "xxxxxx-xxx-xxxx-xxxx-xxxxxxxxxx"

// 1. URL

var url:NSURL = NSURL(string: path)!

// 2. 请求(可以改的请求)

var request:NSMutableURLRequest = NSMutableURLRequest(URL: url)

// ? POST

// 默认就是GET请求

request.HTTPMethod ="POST"

// ? 数据体

var jsonData:NSData? =nil

do {

jsonData = tryNSJSONSerialization.dataWithJSONObject(params, options:NSJSONWritingOptions.PrettyPrinted)

} catch {

}

// 将字符串转换成数据

request.HTTPBody = jsonData

request.setValue("xxxxxx-xxx-xxxx-xxxx-xxxxxxxxxx", forHTTPHeaderField:"X-xxxx-App-Token")

NSURLConnection.sendAsynchronousRequest(request, queue:NSOperationQueue()) { (res, data, error)in

let str =NSString(data: data!, encoding:NSUTF8StringEncoding)

print(str)

}

//#pragma mark - POST登录

func posttoken()

{

var path ="http://xxxxxxxxx/app/token/request_token"

let params:NSMutableDictionary = NSMutableDictionary()

params["app_id"] = "000000000000000000000"

params["app_secret"] ="000000000000000000000"

params["mobile_id"] ="000000000000000000000"

// 1. URL

var url:NSURL = NSURL(string: path)!

// 2. 请求(可以改的请求)

var request:NSMutableURLRequest = NSMutableURLRequest(URL: url)

// ? POST

// 默认就是GET请求

request.HTTPMethod ="POST"

// ? 数据体

var jsonData:NSData? =nil

do {

jsonData = tryNSJSONSerialization.dataWithJSONObject(params, options:NSJSONWritingOptions.PrettyPrinted)

} catch {

}

// 将字符串转换成数据

request.HTTPBody = jsonData

// 3. 连接,异步

NSURLConnection.sendAsynchronousRequest(request, queue:NSOperationQueue()) { (res, data, error)in

if(error ==nil){

var dict:NSDictionary? =nil

do {

dict = try NSJSONSerialization.JSONObjectWithData(data!, options:NSJSONReadingOptions.init(rawValue:0)) as!NSDictionary

} catch {

}

//将str转换为字典

//{"data":

//{"token":"2e2f6b61-8101-49cf-b7dd-7cfea6f0c499","expire_at":1462885914}

// }

//取data的值

var data:NSDictionary = dict!["data"] as! NSDictionary

//取token的值

var token = data["token"]as! String

print(token)

}
