如何通过API从iOS应用程序发出http请求

Question

我正在使用 Xcode 制作一个应用程序，允许用户搜索数据库。这是 goodzer.com 数据库，我想知道如何将其 API 放入 iOS 应用程序内的 http 请求中。请有任何帮助。

Answer 1

使用RestKit或AFNetworking等框架。它们都非常易于使用，可让您立即连接到 RESTful API。

您需要通过他们的网站注册 API 密钥。

搜索他们的数据库看起来像这样（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);
}];

这将返回类似以下内容：

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