我正在为用PHP开发的REST API编写一些示例代码片段,虽然我可以设法获得一个"Ruby“示例,但我还没有找到一个像样的ASP.NET (图形)示例。我想知道是否有ASPer可以帮助翻译下面的PHP,它发出一个以JSON字符串作为有效负载的POST请求。
需要注意的主要事情是,POST需要一个命名参数"data“,它是一个JSON字符串。
$key='XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX'; // This would be your customer key
$map='USA';
$accountid='000'; // this would be your account id
// add some zips to an array
$zips[]=22201;
$zips[]=90210;
$zips[]=10001;
// We encode an array into JSON
$data = array("map" => $map, "zips"=>$zips, "accountid" => $accountid, "custkey" => $key);
$data_string = json_encode($data);
// IMPORTANT - the API takes only one POST parameter - data
$postdata="data=$data_string";
// we use curl here, but Zend has Rest interfaces as well...
$ch = curl_init('https://www.example.com//test/');
curl_setopt($ch, CURLOPT_CUSTOMREQUEST, 'POST');
curl_setopt($ch, CURLOPT_POSTFIELDS, $postdata);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_POST, 1); // make sure we submit a POST!
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, 0);
curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, 0);
$result = curl_exec($ch);
if (curl_errno($ch)) {
$result=curl_error($ch);
} else {
curl_close($ch);
}
$jsonObj=json_decode($result);
if($jsonObj->success){
$coordinates=$jsonObj->coordinates;
foreach($coordinates->coordinates as $coord){
//... application logic here ( construct XML for the map )
}
}谢谢你的帮助--我讨厌发布这样的东西,但也许它将来也会对其他人有帮助!

作为对评论的回应-我真正的帮助请求来自于缺乏一个ASP环境来调试/测试一个例子。例如- @Chris发布了一个链接,虽然从表面上翻译它看起来微不足道(尝试如下),但我的问题是我不仅仅是以普通的POST方式发送数据:
param=val¶m2=val2 它需要像这样:
data={JSONString}其中JSONString是由关联数组生成的。那么问题就出现在ASP中的关联数组(或者更确切地说没有关联数组?-- http://blog.cloudspotting.co.uk/2010/03/26/associative-arrays-in-asp-net/),然后如何将不存在的关联数组编码成JSON字符串,或者如果我尝试使用NamedValueCollection呢?ASP中对JSON的支持似乎也参差不齐,所以我肯定会需要一个特殊的接口?
using System.Web;
Uri address = new Uri("http://www.example.com/test/");
// Create the web request
HttpWebRequest request = WebRequest.Create(address) as HttpWebRequest;
// Set type to POST
request.Method = "POST";
request.ContentType = "application/x-www-form-urlencoded";
string key = "XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX";
string map = "USA";
string accountid = "000";
string data ="";
NameValueCollection data = new NameValueCollection();
data.Add("custkey", key);
data.Add("map", map);
data.Add("accountid", accountid);由于ASP实际上没有关联数组,如何将数据转换为JSON?
string jsondata="";
StringBuilder data = new StringBuilder();在使用UrlEncoding时,下面这行代码会中断吗?
data.Append("data=" + HttpUtility.UrlEncode(jsondata));
// Create a byte array of the data we want to send
byte[] byteData = UTF8Encoding.UTF8.GetBytes(data.ToString());
// Set the content length in the request headers
request.ContentLength = byteData.Length;
// Write data
using (Stream postStream = request.GetRequestStream())
{
postStream.Write(byteData, 0, byteData.Length);
}
// Get response
using (HttpWebResponse response = request.GetResponse() as HttpWebResponse)
{
// Get the response stream
StreamReader reader = new StreamReader(response.GetResponseStream());
// Console application output
string jsonResponse =reader.ReadToEnd());
}所以我想我的问题应该给出上面被黑客攻击的例子--有人能告诉我这是不是正确的,或者提供其他帮助?

你有没有尝试过jSon.Net?http://james.newtonking.com/pages/json-net.aspx示例:
Product product = new Product();
product.Name = "Apple";
product.Expiry = new DateTime(2008, 12, 28);
product.Price = 3.99M;
product.Sizes = new string[] { "Small", "Medium", "Large" };
string json = JsonConvert.SerializeObject(product);
//{
// "Name": "Apple",
// "Expiry": "2008-12-28T00:00:00",
// "Price": 3.99,
// "Sizes": [
// "Small",
// "Medium",
// "Large"
// ]
//}
Product deserializedProduct = JsonConvert.DeserializeObject<Product>(json);结合this tool,我发现它是目前最好的.Net/JSon组合。
