如何使用Zomato API對數據進行身份驗證和解析

Question

使用Zomato API密鑰，您如何進行身份驗證，搜索餐館並解析數據？

Answer 1

見代碼示例：

let zomatoKey = "<Your API Key>"   
    let centerLatitude = 19.06558, centerLongitude = 72.86215 
    let urlString = "https://developers.zomato.com/api/v2.1/search?&lat=\(centerLatitude)&lon=\(centerLongitude)"; 
    let url = NSURL(string: urlString) 

    if url != nil { 
     let request = NSMutableURLRequest(URL: url!) 
     request.HTTPMethod = "GET" 
     request.addValue("application/json", forHTTPHeaderField: "Accept") 
     request.addValue(zomatoKey, forHTTPHeaderField: "user_key") 

     let task = NSURLSession.sharedSession().dataTaskWithRequest(request, completionHandler: {(data, response, error) -> Void in 
      if error == nil { 
       let httpResponse = response as! NSHTTPURLResponse! 

       if httpResponse.statusCode == 200 { 
        do { 
         if let json = try NSJSONSerialization.JSONObjectWithData(data!, options: NSJSONReadingOptions.MutableContainers) as? NSDictionary { 
          if let restaurants = json["restaurants"] as? [NSDictionary] { 
           for rest in restaurants { 
            var searchResult = [String:AnyObject?]() 
            let restaurant = rest["restaurant"] as! NSDictionary 
            print(restaurant["id"] as? NSString) 
            print(restaurant["average_cost_for_two"] as? NSNumber) 
            print(restaurant["cuisines"] as? String) 
            print(restaurant["url"] as? String) 
            print(restaurant["thumb"] as? String) 
            if let location = restaurant["location"] as? NSDictionary { 
             print(location["address"] as? String) 
             print(location["city"] as? String) 
             print((location["latitude"] as? NSString).doubleValue) 
             print((location["longitude"] as? NSString).doubleValue) 
            } 
            print(restaurant["menu_url"] as? String) 
            print(restaurant["name"] as? String) 
            print(restaurant["phone_numbers"] as? String) 
            if let user_rating = restaurant["user_rating"] as? NSDictionary { 
             print(user_rating["aggregate_rating"] as? NSString) 
             print(user_rating["rating_color"] as? String) 
             print((user_rating["votes"] as? NSNumber)).doubleValue) 
            } 
           } 
          } 
         } 

        } catch { 
         print(error) 
        } 
       } 
      } 
     }) 

     task.resume() 
    }

這是我實現假設你有一個一流的餐廳

func getRestaurants() { 

    let url = NSURL(string: zomatoURLString) 

    if url != nil { 
     let request = NSMutableURLRequest(URL: url!) 
     request.HTTPMethod = "GET" 
     request.addValue("application/json", forHTTPHeaderField: "Accept") 
     request.addValue(zomatoKey, forHTTPHeaderField: "user_key") 

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

      if let error = error { 
       print(error) 
       return 
      } 

      //Parse Json data 

      if let data = data { 
       self.restaurants = self.parseJsonData(data) 

       //reload table 
       NSOperationQueue.mainQueue().addOperationWithBlock({() -> Void in 
        self.tableView.reloadData() 
       }) 

      } 
     }) 

     task.resume() 

    } 
} 


func parseJsonData(data: NSData) -> [Restaurant] { 

    do { 
     let jsonResult = try NSJSONSerialization.JSONObjectWithData(data, options: NSJSONReadingOptions.MutableContainers) as? NSDictionary 

     //Parse JSON DATA 
     let jsonRestaurants = jsonResult?["restaurants"] as! [AnyObject] 

     for res in jsonRestaurants { 
      let restaurant = Restaurant() 
      let myRestaurant = res["restaurant"] as! NSDictionary 
      restaurant.restaurantName = myRestaurant["name"] as! String 
      restaurant.restaurantType = myRestaurant["cuisines"] as! String 
      restaurant.restaurantImage = myRestaurant["thumb"] as! String 
      let location = myRestaurant["location"] as! [String: AnyObject] 
      restaurant.restaurantLocation = location["address"] as! String 
      restaurants.append(restaurant) 
     } 
    } catch { 
     print(error) 
    } 
    return restaurants 
}

如果運行您的遊樂場代碼，需要增加以下內容：

import PlaygroundSupport 

// [...] 

PlaygroundPage.current.needsIndefiniteExecution = true
