谁能帮我解决这个 tnx。
最佳答案
我找到了一个更好的答案..
创建一个SecurityCertificateManager
import Foundation
import Alamofire
class SecurityCertificateManager {
static let sharedInstance = SecurityCertificateManager()
let defaultManager: Alamofire.SessionManager = {
let serverTrustPolicies: [String: ServerTrustPolicy] = [
"12.3.3.3": .disableEvaluation
]
let configuration = URLSessionConfiguration.default
configuration.httpAdditionalHeaders = Alamofire.SessionManager.defaultHTTPHeaders
return Alamofire.SessionManager(
configuration: configuration,
serverTrustPolicyManager: ServerTrustPolicyManager(policies: serverTrustPolicies)
)
}()
}
然后这样调用它
let service = CommanLinksUtility().getServiceAuthUrl()
let ticket = UserDefaults.standard.value(forKey: "servicket") as! String
let baseUrl = "https://12.3.3.3:5051/api/v1/user/find/all/1"
let header = [ "content-type" : "application/json", "url": service, "ticket" : ticket ]
SecurityCertificateManager.sharedInstance.defaultManager.request(baseUrl, method: .get, parameters: header as? [String : AnyObject], encoding: URLEncoding.queryString, headers: header)
.responseJSON { response in
let jsonResult = JSON(data: response.data!)
for anItem in jsonResult["result"].arrayValue {
}
}
