如何在Swift 4中使用Alamofire 4.7解析JSON [英] How to parse JSON using Alamofire 4.7 in Swift 4
问题描述
我知道之前曾问过这个问题,但是答案是在Swift 3中使用的是旧版本的Alamofire。
I know this question was asked before, but answers were in Swift 3 and using older versions of Alamofire.
问题:可以吗? t弄清楚如何从JSON响应中检索数据,主要是 api_key 。
Problem: Can't figure out how to retrieve data from JSON response, mainly api_key.
以下是我的响应代码:
Alamofire.request(serverLink!, headers: headers).responseJSON{ response in
if response.value != nil {
//Some code to get api_key
print(response)
} else {
print("error")
}
当我打印(响应)
时,我得到以下信息:
When I print(response)
I get the following:
SUCCESS: {
user = {
"api_key" = 9a13f31770b80767a57d753961acbd3a18eb1370;
"created_on" = "2010-09-30T12:57:42Z";
firstname = Paul;
id = 4;
"last_login_on" = "2018-03-27T10:15:10+03:00";
lastname = Smith;
login = admin;
mail = "admin@demo.com";
status = 1;
};
}
我需要得到的是
api_key = 9a13f31770b80767a57d753961acbd3a18eb1370;
"api_key" = 9a13f31770b80767a57d753961acbd3a18eb1370;
它可以是数组形式,dict或仅包含以下字符串:
It could be in form of array, dict or just string containing:
9a13f31770b807 ...
9a13f31770b807...
有人可以向我解释如何从此请求中获取(解码)吗?
Could someone please explain to me how to get(decode) it from this request?
编辑
print(response.result。值):
RESPONSE: Optional({ user = { "api_key" = 9a13f31770b80767a57d753961acbd3a18eb1370; "created_on" = "2010-09-30T12:57:42Z"; firstname = Paul; id = 4; "last_login_on" = "2018-03-27T11:10:25+03:00"; lastname = Smith; login = admin; mail = "admin@demo.com"; status = 1; }; })
推荐答案
根据 docs ,这是访问序列化JSON响应的方式:
As per the docs, this is how you access the serialised JSON response:
if let json = response.result.value as? [String: Any] {
print("JSON: \(json)") // serialized json response
}
要访问 api_key
,您只需先打开成功字典和用户字典,然后就可以访问用户字典中的api_key属性
To access api_key
you just need to unwrap the success and user dictionaries first and then you can access the api_key property in the user dictionary.
guard let user = json["user"] as? [String: Any],
let apiKey = user["api_key"] as? String else {
print("Failed to parse JSON")
return
}
print(apiKey)
