JSON从C#发送但未在php中作为JSON接收

我的目的是将JSON从C#发送到PHP,然后在PHP端进一步解码,以便将其用于我的目的。
PHP结束时的错误是:

  

警告:json_decode()期望参数1为字符串,数组在第24行的/home3/alsonsrnd/public_html/test/sync.php中给出

我使用以下代码使用C#发送JSON到我的PHP代码:

  private void sendData()
     {
        var httpWebRequest = (HttpWebRequest)WebRequest.Create("http://alnnovative.com/test/sync.php");
        httpWebRequest.ContentType = "text/json";
        httpWebRequest.Method = "POST";

        using (var streamWriter = new StreamWriter(httpWebRequest.GetRequestStream()))
        {
            string json = "{\"user\":\"test\"," +
                          "\"password\":\"bla\"}";

            streamWriter.Write(json);
            streamWriter.Flush();
            streamWriter.Close();
        }

        var httpResponse = (HttpWebResponse)httpWebRequest.GetResponse();
        using (var streamReader = new StreamReader(httpResponse.GetResponseStream()))
        {
            var result = streamReader.ReadToEnd();
        }
    }

在PHP上我使用条带斜线和json_decode()来解码JSON。我的PHP代码给出的错误是接收到的字符串是一个数组而不是JSON,因此它不能使用json_decode对其进行解码。可能是什么原因呢?因为我从C#发送正确格式的JSON

我的PHP代码是:

if($_SERVER['REQUEST_METHOD'] == 'POST')
{
    $json=$_POST;
    if (get_magic_quotes_gpc()){
        $json = stripslashes($json);
    }

    //Decode JSON into an Array
    $data = json_decode($json);
}

答案 0 :(得分:0)

首先,您必须更改Content-Type标题

httpWebRequest.ContentType = "application/x-www-form-urlencoded";

其次,您要以错误的格式发送数据

using (var streamWriter = new StreamWriter(httpWebRequest.GetRequestStream()))
            {
                string json = "json=" + "{\"user\":\"test\"," +
                              "\"password\":\"bla\"}"; ;

                streamWriter.Write(json);
                streamWriter.Flush();
                streamWriter.Close();
            }

最后,你以错误的方式接收数据,$ _POST是一个数组,所以

if($_SERVER['REQUEST_METHOD'] == 'POST' && isset($_POST['json']))
{
    $json=$_POST['json'];
    if (get_magic_quotes_gpc()){
        $json = stripslashes($json);
    }
    //Decode JSON into an Array
    $data = json_decode($json, true);
}
