我将一些参数传递给api,完成添加到购物车功能.但是当我传递参数时,它显示崩溃
JSON中的无效顶级类型写’我知道我的传递参数中存在问题.请帮帮我!.怎么做.请帮帮我!!!
这是我传递的参数的json格式!!:
{ "cartType" : "1","cartDetails" : { "customerID" : "u","cartAmount" : "6999","cartShipping" : "1","cartTax1" : "69","cartTax2" : "","cartTax3" : "","cartCouponCode" : "","cartCouponAmount" : "","cartPaymentMethod" : "","cartProductItems" : { "productID" : "9","productPrice" : "6999","productQuantity" : "1" } } }
我更新的解决方案
func addtocartapicalling () { let headers = [ "cache-control": "no-cache","postman-token": "4c933910-0da0-b199-257b-28fb0b5a89ec" ] let jsonObj:Dictionary<String,Any> = [ "cartType" : "1","cartDetails" : [ "customerID" : "sathish","cartProductItems" : [ "productID" : "9","productQuantity" : "1" ] ] ] if (!JSONSerialization.isValidJSONObject(jsonObj)) { print("is not a valid json object") return } if let postData = try? JSONSerialization.data(withJSONObject: jsonObj,options: JSONSerialization.WritingOptions.prettyPrinted) { let request = NSMutableuRLRequest(url: NSURL(string: "http://expapi.PHP")! as URL,cachePolicy: .useProtocolCachePolicy,timeoutInterval: 10.0) request.httpMethod = "POST" request.allHTTPHeaderFields = headers request.httpBody = postData let session = URLSession.shared let dataTask = session.dataTask(with: request as URLRequest,completionHandler: { (data,response,error) -> Void in if (error != nil) { ///print(error) } else { dispatchQueue.main.async(execute: { if let json = (try? JSONSerialization.jsonObject(with: data!,options: [])) as? Dictionary<String,AnyObject> { let status = json["status"] as? Int; if(status == 1) { print("SUCCESS....") if (json["CartID"] as? Int?) != nil { dispatchQueue.main.async(execute: { print("INSIDE CATEGORIES") self.addtocartdata.append(Addtocartmodel(json:CartID)) }) } } } }) } }) dataTask.resume() } }
附加值的最后一个问题:
在我的模型中,数据类看起来像这样:
class Addtocartmodel { var cartid : Int? init(json:NSDictionary) { self.cartid = json["CartID"] as? Int } }
解决方法
你的json有一些错误的格式.在swift中使用字典比json清楚得多,并使用JSONSerialization将字典转换为json字符串.
代码如下所示:
func addtocartapicalling () { let headers = [ "cache-control": "no-cache",error) -> Void in if (error != nil) { print(error) } else { dispatchQueue.main.async(execute: { if let json = (try? JSONSerialization.jsonObject(with: data!,AnyObject> { let status = json["status"] as? Int; if(status == 1) { print("SUCCESS....") print(json) if let CartID = json["CartID"] as? Int { dispatchQueue.main.async(execute: { print("INSIDE CATEGORIES") print("CartID:\(CartID)") self.addtocartdata.append(Addtocartmodel(json:json)) }) } } } }) } }) dataTask.resume() } }
