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"; 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"; 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)更多推荐
