Question

我正在尝试将NSURLRequest HTTPBody从NSData转换为Dictionary，以便访问其参数并运行检查。

 var parameters: [NSObject: AnyObject?] = [
            "method": "foo",
        ]
        var urlRequestString = "www.foobar.com/api/aMethod"
        var urlRequest = AFOAuth2Manager().requestSerializer.requestWithMethod("POST",
            URLString:urlRequestString ,
            parameters: postParameters,
            error: nil)

在另一种方法中，我尝试对上面构建的urlRequest进行检查，以确保NSURLRequest中的"method"包含正确的值"foo"。

我需要的是将HTTPBody转换为Dictionary（[NSObject: AnyObject]）这样我就可以检查"method"参数是否包含我需要的值。

我怎样才能实现这个目标？

Answer 1

试试这个：

func queryDictionaryForQueryString(query: String) -> Dictionary<String, String> {
    var dictionary = [String: String]()

    for keyValueString in query.componentsSeparatedByString("&") {
        var parts = keyValueString.componentsSeparatedByString("=")
        if parts.count < 2 { continue; }

        var key = parts[0].stringByRemovingPercentEncoding!
        var value = parts[1].stringByRemovingPercentEncoding!

        dictionary[key] = value
    }

    return dictionary
}

然后你可以

let httpBody = urlRequest.HTTPBody
let httpBodyString = NSString(data: httpBody!, encoding: NSUTF8StringEncoding) as! String
let queryDictionary = queryDictionaryForQueryString(httpBodyString)
println(queryDictionary["method"])

这是我的更多Swifty 3.0 NSURL扩展，以实现这一目标，无需安全：

extension NSURL {

    var paramsDictionary: [String : String]? {

        guard let parameterString = parameterString else {
            return nil
        }

        var dictionary: [String : String] = [:]
        parameterString.components(separatedBy: "&").forEach {
            let componants = $0.components(separatedBy: "=")
            guard let name = componants[0].removingPercentEncoding, let value = componants[1].removingPercentEncoding else {
                return
            }
            dictionary[name] = value
        }
        return dictionary.isEmpty ? nil : dictionary
    }
}

var url = NSURL(string: "https://www.testWebSite.com/index.php;param=value&testParam=test&thingParam=thing")
let params = url?.paramsDictionary //results in "Optional(["thingParam": "thing", "testParam": "test", "param": "value"])"

如何检索NSURLRequest的HTTPBody参数到字典：Swift中的[NSObject：AnyObject]
