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()
}
}
