Question

我最近升级到了Alamofire 2.0，现在我的Put请求失败了400错误，之前它正常工作。我用代码执行调用：

Alamofire.request(Router.Put(query: url, params: params, encoding: .JSON))
    .validate()
    .responseJSON() {
        (request, response, result) in

        print("request: \(request)")
        print("response: \(response)")
        print("result: \(result)")

        switch result {
        case .Success(_):
            // success
        case .Failure(let data, _):
            // error occured
        }
}

和我的自定义路由器类：

enum Router: URLRequestConvertible {

    case Get(query: String, params: [String: AnyObject]?)
    case Post(query: String, params: [String: AnyObject]?)
    case Put(query: String, params: [String: AnyObject]?, encoding: ParameterEncoding)
    case Delete(query: String, params: [String: AnyObject]?)

    var URLRequest: NSMutableURLRequest {
        var encodeMethod: Alamofire.ParameterEncoding = Alamofire.ParameterEncoding.URL

        // Default to GET
        var httpMethod: String = Alamofire.Method.GET.rawValue

        let (path, parameters): (String, [String: AnyObject]?) = {
            switch self {
            case .Get(let query, let params):
                // Set the request call
                httpMethod = Alamofire.Method.GET.rawValue
                // Return the query
                return (query, params)
            case .Post(let query, let params):
                // Set the request call
                httpMethod = Alamofire.Method.POST.rawValue
                // Return the query
                return (query, params)
            case .Put(let query, let params, let encoding):
                // Set the request call
                httpMethod = Alamofire.Method.PUT.rawValue
                // Set the encoding
                encodeMethod = encoding
                // Return the query
                return (query, params)
            case .Delete(let query, let params):
                // Set the request call
                httpMethod = Alamofire.Method.DELETE.rawValue
                // Return the query
                return (query, params)
            }
        }()

        // Create the URL Request
        let URLRequest = NSMutableURLRequest(URL: NSURL(string: Globals.BASE_URL + path)!)
        // set header fields
        if let key = NSUserDefaults.standardUserDefaults().stringForKey(Globals.NS_KEY_SESSION) {
            URLRequest.setValue(key, forHTTPHeaderField: "X-XX-API")
        }
        // Add user agent
        if let userAgent = NSUserDefaults.standardUserDefaults().stringForKey(Globals.NS_KEY_USER_AGENT) {
        URLRequest.setValue(userAgent, forHTTPHeaderField: "User-Agent")
        }

        // Set the HTTP method
        URLRequest.HTTPMethod = httpMethod

        URLRequest.cachePolicy = NSURLRequestCachePolicy.ReloadIgnoringLocalCacheData

        return encodeMethod.encode(URLRequest, parameters: parameters).0
    }
}

响应是：

，而不是呼叫成功

response: Optional(<NSHTTPURLResponse: 0x7fcee15b34d0> { URL: https://apiurl } { status code: 400, headers {
"Cache-Control" = "no-cache";
"Content-Length" = 26;
"Content-Type" = "application/json; charset=utf-8";
Date = "Tue, 15 Sep 2015 15:33:50 GMT";
Expires = "-1";
Pragma = "no-cache";
Server = "Microsoft-IIS/8.5";
} })

我调查了问题，在服务器端，Content-Type作为请求的空白，应该以{{1}}的形式进入。当请求中有正文数据时，application/json应自动添加。我设置了参数：

Content-Type

这有什么我可以错过的吗？在我升级到// Save the profile var params: [String: AnyObject] = ["indexPhoto": userProfile.indexPhoto, "dob": df.stringFromDate(userProfile.dob) as NSString, "identAs": userProfile.identAs] // Add manually since creating the dictionary all at once is too much for swift to handle params.updateValue(String(format:"%.2f", userProfile.heightIn), forKey: "heightIn") params.updateValue(String(format:"%.2f", userProfile.weightLbs), forKey: "weightLbs") params.updateValue(userProfile.eyes, forKey: "eyes") params.updateValue(userProfile.hair, forKey: "hair") ...之前，此通话工作正常。

也许有不同的方式，但我通过发送空params而不是nil修复了同样的问题。我在使用.PUT时不使用任何参数，因为该服务器不知道如何编码请求和响应（即使我在头文件中明确设置内容类型，我在服务器上收到空白内容类型）所以我的解决方案是发送空的参数，如下面的代码。希望它可以帮到某人。

var url = https://api.mysite.com/v1/issue/369613/delete

let params = ["":""]

let headers = NetworkConnection.addAuthorizationHeader(token, tokenType: tokenType)
manager.request(.PUT, url, parameters: params, encoding: .JSON, headers: headers)
        .responseJSON { response in
            if let JSONdata = response.result.value {
                print("JSONdata: \(JSONdata)")
            }
}

使请求失败的Alamofire 2.0
