前言：
swift這個(gè)不穩(wěn)定，真的是蛋疼無(wú)比，尤其是語(yǔ)法變更。第三方更新不及時(shí)，也導(dǎo)致很多問(wèn)題。anyway閑暇之余手里不忙來(lái)“深入淺出”的學(xué)習(xí)一下皮毛。

接昨天做的Swift中自定義cell，來(lái)進(jìn)一步模仿著項(xiàng)目的進(jìn)行~
在swift中再不想oc一樣.h/.m分明，講道理最開(kāi)始接觸oc的時(shí)候覺(jué)得這樣才好啊，聲明和實(shí)現(xiàn)分開(kāi)寫(xiě)。不過(guò)后來(lái)寫(xiě)swift又覺(jué)得寫(xiě)在一個(gè).swift里這么寫(xiě)也很爽。
具體實(shí)現(xiàn)步驟：
1.新建一個(gè)類(lèi)，姑且取名為VDNetTools吧
2.在其中進(jìn)行網(wǎng)絡(luò)請(qǐng)求的書(shū)寫(xiě)吧
GET請(qǐng)求
//單例
static let share = VDNetTools()
func getWithPath(path: String,paras: Dictionary<String,Any>?,success: @escaping ((_ result: Any) -> ()),failure: @escaping ((_ error: Error) -> ())) {
var i = 0
var address = path
if let paras = paras {
for (key,value) in paras {
if i == 0 {
address += "?\(key)=\(value)"
}else {
address += "&\(key)=\(value)"
}
i += 1
}
}
let url = URL(string: address.addingPercentEncoding(withAllowedCharacters: CharacterSet.urlQueryAllowed)!)
let session = URLSession.shared
let dataTask = session.dataTask(with: url!) { (data, respond, error) in
if let data = data {
if let result = try? JSONSerialization.jsonObject(with: data, options: .allowFragments){
success(result)
}
}else {
failure(error!)
}
}
dataTask.resume()
}
POST請(qǐng)求
func postWithPath(path: String,paras: Dictionary<String,Any>?,success: @escaping ((_ result: Any) -> ()),failure: @escaping ((_ error: Error) -> ())) {
var i = 0
var address: String = ""
if let paras = paras {
for (key,value) in paras {
if i == 0 {
address += "\(key)=\(value)"
}else {
address += "&\(key)=\(value)"
}
i += 1
}
}
let url = URL(string: path)
var request = URLRequest.init(url: url!)
request.httpMethod = "POST"
print(address)
request.httpBody = address.data(using: .utf8)
let session = URLSession.shared
let dataTask = session.dataTask(with: request) { (data, respond, error) in
if let data = data {
if let result = try? JSONSerialization.jsonObject(with: data, options: .allowFragments) {
success(result)
}
}else {
failure(error!)
}
}
dataTask.resume()
}
怎么使用呢
@objc fileprivate func loadData() {
let path = "請(qǐng)求的地址"
// let dict = ["userid":1]
VDNetTools.share.getWithPath(path: path, paras: nil, success: { (result) in
// print(result)
//如果設(shè)置options為JSONSerialization.WritingOptions.prettyPrinted，則打印格式更好閱讀
let data = try? JSONSerialization.data(withJSONObject: result, options: JSONSerialization.WritingOptions.prettyPrinted)
//Data轉(zhuǎn)換成String打印輸出
let str = String(data:data!, encoding: String.Encoding.utf8)
//輸出json字符串
print("Json Str:"); print(str)
}) { (error) in
print(error)
}
}
