Question

我在POST查询中遇到了一些问题;请帮忙。它总是向我发送400 Bad请求响应。我已经彻底检查了一切，但它只是不起作用。请帮忙。

代码是 -

struct RegisterService {

var authToken: String = ""
var baseURL = NSURL(string: "")

func getToken(name: String, email: String, password: String, cfmpassword: String, completion: (AuthToken? -> Void)) {

    let request = NSMutableURLRequest(URL: baseURL!)
    let session = NSURLSession.sharedSession()
    request.HTTPMethod = "POST"

    let params = ["accept":"on", "cfmpassword":"\(cfmpassword)", 
        "email":"\(email)", "name":"\(name)", "password":"\(password)"] 
        as Dictionary<String, AnyObject>

    do {
        request.HTTPBody = try NSJSONSerialization.dataWithJSONObject(params, options: [])
        request.addValue("application/json", forHTTPHeaderField: "Content-Type")
        request.addValue("application/json", forHTTPHeaderField: "Accept")
    } catch {
        print("Request Unsuccessful")
    }

    let task = session.dataTaskWithRequest(request, completionHandler: {data, response, error -> Void in

        print(request)
        print(data)
        print(response)
        if let httpResponse = response as? NSHTTPURLResponse {
            switch httpResponse.statusCode {
            case 200:
                // 2. Create JSON object with data
                do {
                    let jsonDictionary = try NSJSONSerialization.JSONObjectWithData(data!, options: []) as? [String: AnyObject]
                    let authToken = AuthToken(tokenDictionary: jsonDictionary!)
                    completion(authToken)
                } catch {
                    print("Fetch failed: \((error as NSError).localizedDescription)")
                }
            default:
                print("GET request not successful. HTTP status code: \(httpResponse.statusCode)")
                NSOperationQueue.mainQueue().addOperationWithBlock {
                    completion(nil)
                }
            }
        } else {
            print("Error: Not a valid HTTP response")
            NSOperationQueue.mainQueue().addOperationWithBlock {
                completion(nil)
            }
        }
    })

    task.resume()
}
}

let params = ["accept":"on", "cfmpassword":"\(cfmpassword)", "email":"\(email)", "name":"\(name)", "password":"\(password)"] as Dictionary<String, AnyObject>

let boundary:String = "---------------------------14737809831466499882746641449"

let body:NSMutableData = NSMutableData()

if params != nil
{
      for (key, value) in params!
      {
            body.appendString("--\(boundary)\r\n")
            body.appendString("Content-Disposition: form-data; name=\"\(key)\"\r\n\r\n")
            body.appendString("\(value)\r\n")
      }
}

body.appendString("--\(boundary)--\r\n")
request.setValue("\(body.length)", forHTTPHeaderField:"Content-Length")
request.HTTPBody = body
