Google search with Alamofire errors (iOS, Swift, JSON, HTML)

Question

Please, help! I was stuck for several months trying to do a simple Google Search on my Swift app, and I passed me through the wall!

I tried both with ALAMOFIRE and with a regular URLRequest, but since the result seems to be in HTML format only, I cannot parse the results correctly. Even when you look in HTML, the code is for a web page and it does NOT include search results.

I LOVE the search results to be in a simple dictionary. Here is my code:

let googleUrl:String = "https://cse.google.com/cse/publicurl?&output=json&cx=<MyGoogleKey>:<MyGoogleSKey>&q=q=+normal+search" // Trying with AlamoFire: Alamofire.request(googleUrl).response { response in print("Request: \(response.request)") print("Response: \(response.response)") print("Error: \(response.error)") }.responseJSON(completionHandler: { response in print("ResponseJSON: \(response)") }).responseData(completionHandler: { response in print("ResponseData: \(response)") }).responseString(completionHandler: { response in print("ResponseString: \(response)") }) 

As you can see, I am trying to respond in almost all types supported by Alamofire and I GET ANYTHING.

Here is error # 1 (. ResponseJSON ):

Data cannot be read because it is not in the correct format. ResponseJSON: FAILURE: responseSerializationFailed (Alamofire.AFError.ResponseSerializationFailureReason.jsonSerializationFailed (Error Domain = NSCocoaErrorDomain Code = 3840 "Invalid value around character 0." UserInfo = {NSDebugDescription = Invalid value around character 0.}))

Here's DATA Response (. ResponseData strong>): ResponseData: SUCCESS: 4337 bytes

Here is the HTML response (. ResponseString )

ResponseString: SUCCESS:

*> Google Custom Search

(function () {var cookie_path = '/ cse /'; var path_copy = '/ coop /'; window._gaq = window._ga ...._ AND_SO_ON_TILL_FULL_HTML_PAGE_IN_A_STRING .... *

* I only wish I had search results in a simple dictionary ...

Is anyone You are welcome?

It seems you are using a custom search API to embed in web pages.

This documentation is for what you want to do.

Here is an example of using as a search domain.

 import UIKit import Alamofire class ViewController: UIViewController { override func viewDidLoad() { super.viewDidLoad() search(query: "swift") { (results) in for result in results { dump(result) } } } func search(query:String, completion: @escaping (Array<SearchResult>)->()){ let id = "Custom search engine ID" let key = "API key" let url = "https://www.googleapis.com/customsearch/v1?key=\(key)&cx=\(id)&q=\(query)" Alamofire.request(url).responseJSON { (response) in var results = Array<SearchResult>() if let dict = response.value as? Dictionary<String,Any> { if let items = dict["items"] as? Array<Dictionary<String,Any>> { for item in items { if let result = SearchResult(dict: item) { results.append(result) } else { print("Incomplete search result data.") } } } } completion(results) } } } 

I have this structure to better save search results. It does not contain all the values ​​that give JSON results. I just selected them for testing.

 struct SearchResult { var displayLink: String var formattedUrl: String var htmlFormattedUrl: String var htmlSnippet: String var htmlTitle: String var link: String var snippet: String var title: String init?(dict:Dictionary<String,Any>) { guard let displayLink = dict["displayLink"] as? String, let formattedUrl = dict["formattedUrl"] as? String, let htmlFormattedUrl = dict["htmlFormattedUrl"] as? String, let htmlSnippet = dict["htmlSnippet"] as? String, let htmlTitle = dict["htmlTitle"] as? String, let link = dict["link"] as? String, let snippet = dict["snippet"] as? String, let title = dict["title"] as? String else { return nil } self.displayLink = displayLink self.formattedUrl = formattedUrl self.htmlFormattedUrl = htmlFormattedUrl self.htmlSnippet = htmlSnippet self.htmlTitle = htmlTitle self.link = link self.snippet = snippet self.title = title } } 

These are a few results that dump(result) prints.

 ▿ CustomGoogleSearch.SearchResult - displayLink: "stackoverflow.com" - formattedUrl: "https://stackoverflow.com/questions/tagged/swift" - htmlFormattedUrl: "https://stackoverflow.com/questions/tagged/<b>swift</b>" - htmlSnippet: "<b>Swift</b> is an open-source programming language developed by Apple.

Receiving keys

On this page, click the Get A Key button.

Then you need to select or create a Google project, then you will create an API key. So copy it here. let key = "API key"

For the search engine ID, go to the console . Now either select a search engine or create a new one. You will be taken to a page like this.

Press the Search engine ID button, a screen with your ID will appear on the screen, and then enter here let id = "Custom search engine ID"
