此网址与谷歌API缩短，斯威夫特AFNetworking [英] Get url shortened with Google API, AFNetworking in Swift

问题描述

在谷歌文档（ https://developers.google.com/url-shortener/ V1 / getting_started ），使用谷歌URL缩短，我应该如下要求：

In Google documentation (https://developers.google.com/url-shortener/v1/getting_started), to use Google URL shortener, I should make a request as below:

https://www.googleapis.com/urlshortener/v1/url

内容类型：应用程序/ JSON

Content-Type: application/json

{longUrl： http://www.google.com/ }

{"longUrl": "http://www.google.com/"}

他们还说，我将不得不验证：

They also stated that I will have to authenticate:

每一个请求您的应用程序发送给谷歌URL缩短API
  需要确定您的应用程序谷歌。有两种方法来
  找出你的应用程序：使用OAuth 2.0令牌（这也
  授权请求）和/或使用应用程序的API密钥。

"Every request your application sends to the Google URL Shortener API needs to identify your application to Google. There are two ways to identify your application: using an OAuth 2.0 token (which also authorizes the request) and/or using the application's API key."

我选择了公共API密钥验证的方法：我创造了我的iOS应用程序的公钥。然后我用下面的code到POST（AFNetworking，使用SWIFT）：

I chose public API key as a method to authenticate: I create a public key for my iOS app. Then I use the following code to POST (AFNetworking, using Swift):

func getShortURL(longURL: String){
    let manager = AFHTTPRequestOperationManager()
    let params = [
        "longUrl": longURL
    ]
    manager.POST("https://www.googleapis.com/urlshortener/v1/url?key={my_key_inserted}", parameters: params, success: {
        (operation: AFHTTPRequestOperation!,responseObject: AnyObject!) in
            println("JSON: " + responseObject.description)
        },
        failure: { (operation: AFHTTPRequestOperation!,error: NSError!) in
            println("Error while requesting shortened: " + error.localizedDescription)
    })
} 

不过，我得到的日志：错误同时要求缩短：请求失败：错误的请求（400）

However, I got the log: Error while requesting shortened: Request failed: bad request (400).

请告诉我如何解决它。

推荐答案

你所缺的是设置AFNetworking串行此请求的权利。

What you are missing is setting the right AFNetworking serializer for this request.

由于谷歌的反应是JSON，你应该使用 AFJSONRequestSerializer 。

Since the Google response is in JSON, you should use AFJSONRequestSerializer.

添加 manager.requestSerializer = AFJSONRequestSerializer（）是这样的：

    let manager = AFHTTPRequestOperationManager()
    manager.requestSerializer = AFJSONRequestSerializer()
    let params = ["longUrl": "MYURL"]
    manager.POST("https://www.googleapis.com/urlshortener/v1/url?key=MYKEY", parameters: params, success: {(operation: AFHTTPRequestOperation!,responseObject: AnyObject!) in
        println("JSON: " + responseObject.description)
            }, failure: { (operation: AFHTTPRequestOperation!,error: NSError!) in
        println("Error while requesting shortened: " + error.localizedDescription)
    })
