【问题描述】：

我想在 swift 2.2 中使用 Alamofire for i 代码发送带有 .POST 请求的 Json 对象，如下所示：

let dictionary: [String: AnyObject] = [
            "cUserEmail" : "[e-mail]",
            "cUserPassword" : "abc",
            "cDeviceId" : "asdf"
        ]

        let url = NSURL(string: endPoint)

        let request = NSMutableURLRequest(URL:url!)
        request.HTTPMethod = "POST"
        request.setValue("application/json", forHTTPHeaderField: "Content-Type")

        request.HTTPBody = try! NSJSONSerialization.dataWithJSONObject(dictionary, options: NSJSONWritingOptions.PrettyPrinted)

        Alamofire.request(request)
            .responseJSON  response in
                // do whatever you want here
                switch response.result 
                case .Failure(let error):
                    print(error)
                case .Success(let responseObject):
                    print(responseObject)
                
        

但上面提到的代码不起作用。 以前，在objective-c中我使用的代码如下：

AFHTTPRequestOperationManager *manager = [AFHTTPRequestOperationManager manager];
    manager.responseSerializer = [AFJSONResponseSerializer serializer];
    manager.requestSerializer = [AFJSONRequestSerializer serializer];
    [manager.requestSerializer setValue:@"application/json" forHTTPHeaderField:@"Content-Type"];
    manager.securityPolicy.allowInvalidCertificates = YES;
 [manager POST:URLString parameters:dictionary success:^(AFHTTPRequestOperation *operation, id responseObject) 
 failure:^(AFHTTPRequestOperation *operation, NSError *error) 
];

简而言之，我想要 swift 2.2 与 Alamofire 的等效代码。

【参考方案1】：

尝试对这样的正文使用空选项：

request.HTTPBody = try! NSJSONSerialization.dataWithJSONObject(dictionary, options: [])

【参考方案2】：

我通过以下方法找到了我的解决方案 希望它对你有用...

let dictionary: [String: AnyObject] = [
            "cUserEmail" : "[e-mail]",
            "cUserPassword" : "abc",
            "cDeviceId" : "asdf"
        ]

let request2 = Alamofire.request(.POST, "http://localhost:8080/api/v1/register", parameters: dictionary, encoding: .JSON)
request2.validate()
request2.responseJSON(completionHandler:  (let response) in

    let data = response.data!
    do 
        let json = try NSJSONSerialization.JSONObjectWithData(data, options: .AllowFragments)
        print ( "json is \(json)")

     catch 
        print("error serializing JSON: \(error)")

        self.showAlert("Error :\(error)")
    
)
