"Devin Rader"的回答非常完美。对于像我这样的其他用户,以下是SwiftRequest在swift 3.0中的完整转换代码。原始代码由Ricky Robinett提供。
如果有任何错误,请告诉我们。
谢谢。
import Foundation
public class SwiftRequest {
var session = URLSession.shared
public init() {
}
public func get(url: String, auth: [String: String] = [String: String](), params: [String: String] = [String: String](), callback: ((_ err: NSError?, _ response: HTTPURLResponse?, _ body: AnyObject?)->())? = nil) {

request(options: ["url" : url, "auth" : auth, "querystring": qs ], callback: callback )

public func post(url: String, data: [String: String] = [String: String](), auth: [String: String] = [String: String](), callback: ((_ err: NSError?, _ response: HTTPURLResponse?, _ body: AnyObject?)->())? = nil) {
let qs = dictToQueryString(data: data)
request(options: ["url": url, "method" : "POST", "body" : qs, "auth" : auth] , callback: callback)
}
func request(options: [String: Any], callback: ((_ err: NSError?, _ response: HTTPURLResponse?, _ body: AnyObject?)->())?) {
if( options["url"] == nil ) { return }
var urlString = options["url"] as! String
if( options["querystring"] != nil && (options["querystring"] as! String) != "" ) {

urlRequest.httpBody = postData
urlRequest.setValue("\(postData!.count)", forHTTPHeaderField: "Content-length")
}
if( options["auth"] != nil && (options["auth"] as! [String: String]).count > 0) {
var auth = options["auth"] as! [String: String]
if( auth["username"] != nil && auth["password"] != nil ) {

task.resume()
}
func request(url: String, callback: ((_ err: NSError?, _ response: HTTPURLResponse?, _ body: AnyObject?)->())? = nil) {

}
private func dictToQueryString(data: [String: String]) -> String {
var qs = ""
for (key, value) in data {
let encodedKey = encode(value: key)
let encodedValue = encode(value: value)
qs += "\(encodedKey)=\(encodedValue)&"
}
return qs
}
private func encode(value: String) -> String {
let queryCharacters = NSCharacterSet(charactersIn:" =\"#%/<>?@\\^`{}[]|&+").inverted
if let encodedValue:String = value.addingPercentEncoding(withAllowedCharacters: queryCharacters) {
return encodedValue
}
return value
}
}
使用上述类的示例代码,如“Devin Rader”所述
let URL = "https://api.twilio.com/2010-04-01/Accounts/\(myUserIdForBulkSmsMessageSending)/Messages"
var swiftRequest = SwiftRequest();
var data = [
"To" : "+\(replaceNumberToSendSms)",
"From" : "+\(replaceNumberFromSendSms)",
"Body" : message,
"MediaUrl" : theUrlEncodedMessage
];
swiftRequest.post(url: URL,
data: data,
auth: ["username" : myUserIdForBulkSmsMessageSending, "password" : myUserPasswordForBulkSmsMessageSending],
callback: {err, response, body in
if err == nil {
print("Success: \(String(describing: response))")
if let currentBody = body {
}
} else {
print("Error: \(String(describing: err))")
}
});
