如何通過api從iOS應用程序發出http請求

Question

我正在使用xcode制作一個允許用戶搜索數據庫的應用程序。 這是goodzer.com數據庫，我想知道如何將他們的API放入ios應用程序中的http請求。 請幫忙。

Answer 1

使用像RestKit或AFNetworking這樣的框架。 它們都非常易於使用，並且可以立即連接到RESTful API：s。

您需要通過他們的網站注冊API密鑰。

搜索他們的數據庫看起來像這樣（使用AFNetworking）：

NSString url = @"http://api.goodzer.com/products/v0.1/search_in_store/?storeId=fAfVfDCd&query=ipad+case&priceRange=20:50&apiKey=<Your_API_key>";
AFHTTPRequestOperationManager *manager = [AFHTTPRequestOperationManager manager];
[manager GET:url parameters:nil success:^(AFHTTPRequestOperation *operation, id responseObject) {
    NSLog(@"JSON: %@", responseObject);
} failure:^(AFHTTPRequestOperation *operation, NSError *error) {
    NSLog(@"Error: %@", error);
}];

這將返回如下內容：

    "realtime_availability": true,
    "products_found": 199,
    "products": [
        {
