[英]Converting Data from http request from JSON Dictionary of Dictionaries into one Array of Dictionaries in Swift
[英]Retrieving json data from http request in swift
我是新手,因此是個問題。 我想將我的http調用包裝到此簽名的函數中。
func httpPost()-> Any
該代碼有效,但如何將其包裝在所需的functio簽名中。
let headers = [
"Content-Type": "application/json",
"cache-control": "no-cache"
]
let parameters = [
"client_id": "xxx",
"client_secret": "yyy"
] as [String : Any]
let postData = try? JSONSerialization.data(withJSONObject: parameters, options: [])
var request = URLRequest(url: URL(string: "http://xxx.xxx")! 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) { (data, response, error) -> Void in
guard let data = data else {return}
do{
try validate(response)
let json = try JSONSerialization.jsonObject(with: data, options: [])
}catch{
print(error)
}
//print(String(describing: data))
}
dataTask.resume()
我想在這里將json對象返回為Any
在阻塞線程之前,您不能在異步函數中返回直接值,這是一個壞主意,因此您需要完成
func httpPost(completion:@escaping(_ ret:Any?,err:Error?) -> Void)
let headers = [
"Content-Type": "application/json",
"cache-control": "no-cache"
]
let parameters = [
"client_id": "xxx",
"client_secret": "yyy"
] as [String : Any]
let postData = try? JSONSerialization.data(withJSONObject: parameters, options: [])
var request = URLRequest(url: URL(string: "http://xxx.xxx")! 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) { (data, response, error) -> Void in
guard let data = data else {
completion(nil,error)
return
}
do{
try validate(response)
let json = try JSONSerialization.jsonObject(with: data, options: [])
completion(json,nil)
}catch{
print(error)
completion(nil,error)
}
//print(String(describing: data))
}
dataTask.resume()
}
打電話
httpPost { (json,error) in
print(json)
}
也最好將json分別轉換為[Any]
/ [String:Any]
以獲得Array / Dictionary響應
