在Swift中发送带有参数（Parse Server API）的GET请求

Question

这是卷曲。

curl -X GET \ 
-H "X-Parse-Application-Id: XXXX" \ 
-H "X-Parse-REST-API-Key: XXXX" \ 
-G \ 
--data-urlencode "where={\"Area\":\"Vesu\"}" \ 
https://parseapi.back4app.com/classes/RESTAURANT 

如何通过URLSession向何处发送GET请求？

Answer 1

您需要对查询字符串进行编码，然后使用包含baseURL和查询的标头和URL创建URLRequest。最后，您需要拨打dataTask来执行您的请求。

let baseUrl = "https://parseapi.back4app.com/classes/RESTAURANT" 
guard let queryParameters = "where={\"Area\":\"Vesu\"}".addingPercentEncoding(withAllowedCharacters: .urlQueryAllowed) else {return} 
guard let url = URL(string: baseUrl+"?"+queryParameters) else {return} 
var urlRequest = URLRequest(url: url) 
urlRequest.allHTTPHeaderFields = ["X-Parse-Application-Id":"XXXX", "X-Parse-REST-API-Key":"XXXX"] 
URLSession.shared.dataTask(with: urlRequest, completionHandler: { data, response, error in 
    guard error == nil else { 
     print(error!); return 
    } 
    //handle data and/or response 
}).resume()
