The use of afnetworking under iOS development--swift

1, first use cocoapods import, if there is no classmate, you can go to see I wrote about cocopods use of the blog

2, directly on the code:

Import Uikitimport afnetworking//enumeration Definition Request Methodenumhttprequesttype{ CaseGET CasePOST}classAfnettools:afhttpsessionmanager {//single-instance class    StaticLet Shareinstance:afnettools ={Let toolinstance=afnettools () toolInstance.responseSerializer.acceptableContentTypes?. Insert"text/html")        returnToolinstance} ()        ///encapsulating get and POST requests///    ///-Parameters:///-RequestType: Request Method///-Urlstring:urlstring///-Parameters: Dictionary parameters///-Completion: CallbackFunc request (Requesttype:httprequesttype, urlstring:string, Parameters: [String:anyobject]?, Completion: @escaping ( Anyobject?) - ()) {                //Successful callbackLet success = {(Task:urlsessiondatatask, Json:any), ()inchCompletion (JSON asAnyobject?)        }                //Failure CallbackLet failure = {(Task:urlsessiondatatask, error:error), ()inchPrint ("Network request error \ (Error)") Completion (nil)}ifRequestType = = . GET {Get(URLString, Parameters:parameters, Progress:nil, Success:success, failure:failure)}Else{post (urlstring, Parameters:parameters, Progress:nil, Success:success, Failure:failure)}} //write successful and failed callbacks separately in two escape closuresFunc request (Requesttype:httprequesttype, url:string, Parameters: [String:any], Succeed: @escaping ([String:any]? ), Failure: @escaping (Error?) ()) {                //Successful closuresLet Successblock = {(Task:urlsessiondatatask, responseobj:any?)inchSucceed (Responseobj as?[String:any])} //failed closuresLet Failureblock = {(task:urlsessiondatatask?, Error:error)inchfailure (Error)}//Get Request        ifRequestType = = . GET {Get(URL, parameters:parameters, Progress:nil, Success:successblock, Failure:failureblock)} //Post Request        ifRequestType = = .    Post {post (URL, parameters:parameters, Progress:nil, Success:successblock, Failure:failureblock)} }    }

The above is the two-time package request class

3, Call:

@IBAction Func Startrequest (_ Sender:any) {Let paramerts= [            "Opt_type":1,            "size": -,            "Offset": -] AFNetTools.shareInstance.request (requesttype:. GET, URL:"http://apiv2.yangkeduo.com/operation/15/groups", Parameters:paramerts, Succeed: {(response)inchGuard Let Dicarray= response? ["goods_list"] as? [[String:any]]Else {                return} print (Dicarray)}) {(error)inchGuard Let Error= ErrorElse {                return} print (Error)}}

Print as follows:
