转换数组PHP数组到C＃ [英] Converting PHP array of arrays to C#

问题描述

我写一个C＃客户端进行第三方API（我使用的是RestSharp的NuGet包）。他们的文档包含PHP的例子，我必须转换为C＃。他们的大多数样本是足够简单，我已经能够将它们转换为C＃，但我与他们中的一个挣扎，因为它接受一个数组的数组。下面是从他们的文档样本：

  $ PARAMS =阵列（
'user_key'=>'X'， 
'的client_id'=>'X，
'标签'=>阵列（
阵列（
'语言'=>'EN_US'，
'名称'=>'英文标签'，
）
阵列（
'语言'=>'fr_CA'，
'名'=>法国标签 ，
）
）
）; 
 $ CH = curl_init（）; 
 curl_setopt（$ CH，CURLOPT_URL，'https://api.3rdparty.com/xxx/yyy'）; 
 curl_setopt（$ CH，CURLOPT_POST，真正的）; 
 curl_setopt（$ CH，CURLOPT_HTTPHEADER，阵列（'apikey：YOURAPIKEY'））; 
 curl_setopt（$ CH，CURLOPT_POSTFIELDS，http_build_query（$ params）方法）; 
 curl_setopt（$ CH，CURLOPT_RETURNTRANSFER，真正的）; 
 
 $结果= curl_exec（$ CH）; 
  

下面是我到目前为止有：

  VAR标签=新词典<字符串，字符串>（）
 {
 {EN_US，英文标识}，
 {fr_CA ，法国标签} 
}; 
 
变种要求=新RestRequest（/ XXX / YYY，Method.POST）{RequestFormat = DataFormat.Json}; 
 request.AddHeader（apikey，myApiKey）; 
 request.AddParameter（user_key，myUserKey）; 
 request.AddParameter（CLIENT_ID，myClientId）; 
 request.AddParameter（标签？）; 
 
 VAR的客户=新RestSharp.RestClient（https://api.3rdparty.com）
 {
超时=超时，
的UserAgent =我的。 NET REST客户端
}; 
 VAR响应= client.Execute（请求）; 
  

是否有人知道如何转换的标签字典成的格式，就相当于PHP的http_build_query ？

解决方案

http_build_query（$ params）方法产生输出看起来像这样

  user_key = X&安培; CLIENT_ID = X&放大器;标号％5B0％5D％5Blanguage％5D = EN_US&放大器;标号％5B0％5D％5Bname％5D =英语+标签和放大器;标号％5B1％5D％5Blanguage％5D = fr_CA&放大器;标号％5B1％5D％5Bname％5D =法语+标签
  

其中，解码，是这样的：

  user_key = X&安培; CLIENT_ID = X&放大器;标签[0] [语言] = EN_US&放大器;标签[0] [名] =英文标签和放大器;标号[1] [语言] = fr_CA&放大器;标号[1] [名] =法国标签
  

所以，你应该能够做到：

  VAR要求=新RestRequest（/ XXX / YYY，方法。 POST）; 
 request.AddHeader（apikey，myApiKey）; 
 request.AddParameter（user_key，myUserKey）; 
 request.AddParameter（CLIENT_ID，myClientId）; 
的foreach（在labels.Select VAR项目（（对我）=>新建{指数=我，语言= pair.Key，名称= pair.Value}））
 {
 request.AddParameter（的String.Format（标签[{0}] [语言]，item.index），item.language）; 
 request.AddParameter（的String.Format（标签[{0}] [名]，item.index），item.name）; 
} 
  

请注意，从试验，我注意到，RestSharp被编码空间 20％，而不是 + 。但愿不是问题。

I am writing a C# client for a 3rd party API (I'm using the RestSharp nuget package). Their documentation contains PHP examples which I must translate to C#. Most of their samples are simple enough and I have been able to convert them to C# but I am struggling with one of them because it accepts an array of arrays. Here's the sample from their documentation:

$params = array (
    'user_key' => 'X',
    'client_id'=> 'X,
    'label' => array(
        array(
            'language' => 'en_US',
            'name' => 'English label',
        ),
        array(
            'language' => 'fr_CA',
            'name' => 'French label',
        ),
    ),
);
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, 'https://api.3rdparty.com/xxx/yyy'); 
curl_setopt($ch, CURLOPT_POST, true);
curl_setopt($ch, CURLOPT_HTTPHEADER, array('apikey: YOURAPIKEY'));
curl_setopt($ch, CURLOPT_POSTFIELDS, http_build_query($params));
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);

$result = curl_exec($ch);

Here's what I have so far:

var labels = new Dictionary<string, string>() 
{
    { "en_US", "English Label" },
    { "fr_CA", "French Label" }
};

var request = new RestRequest("/xxx/yyy", Method.POST) { RequestFormat = DataFormat.Json };
request.AddHeader("apikey", myApiKey);
request.AddParameter("user_key", myUserKey);
request.AddParameter("client_id", myClientId);
request.AddParameter("label", ???);

var client = new RestSharp.RestClient("https://api.3rdparty.com")
{
    Timeout = timeout,
    UserAgent = "My .NET REST Client"
};
var response = client.Execute(request);

Does anybody know how to convert the "labels" dictionary into a format that would be equivalent to PHP's http_build_query?

解决方案

http_build_query($params) produces output that looks like this:

user_key=X&client_id=X&label%5B0%5D%5Blanguage%5D=en_US&label%5B0%5D%5Bname%5D=English+label&label%5B1%5D%5Blanguage%5D=fr_CA&label%5B1%5D%5Bname%5D=French+label

Which, decoded, looks like:

user_key=X&client_id=X&label[0][language]=en_US&label[0][name]=English label&label[1][language]=fr_CA&label[1][name]=French label

So, you should be able to do:

        var request = new RestRequest("/xxx/yyy", Method.POST);
        request.AddHeader("apikey", myApiKey);
        request.AddParameter("user_key", myUserKey);
        request.AddParameter("client_id", myClientId);
        foreach (var item in labels.Select((pair, i) => new { index = i, language = pair.Key, name = pair.Value }))
        {
            request.AddParameter(string.Format("label[{0}][language]", item.index), item.language);
            request.AddParameter(string.Format("label[{0}][name]", item.index), item.name);
        }

Note that, from experimentation, I have noticed that RestSharp is encoding a space as %20 rather than as +. Hopefully not a problem.
