Question

我的代码工作（是的！）将json发送到服务器..会对重构的任何想法表示感谢

1）我的C＃代码将此json发送到服务器

{\ “名字\”：\ “比尔\”，\ “姓氏\”：\ “盖茨\” \ “电子邮件\”：\ “asdf@hotmail.com \”，\ “deviceUUID \”： \ “ABCDEFGHIJKLMNOPQRSTUVWXYZ \”}

我必须摆脱服务器端的斜线......不好。

2）我正在使用application / x-www-form-urlencoded并且可能想要使用application / json

Person p = new Person();
            p.firstName = "Bill";
            p.lastName = "Gates";
            p.email = "asdf@hotmail.com";
            p.deviceUUID = "abcdefghijklmnopqrstuvwxyz";

            HttpWebRequest request = (HttpWebRequest)WebRequest.Create(targetUri + "newuser.php");
            request.Method = "POST";
            request.ContentType = "application/x-www-form-urlencoded";
            //TODO request.ContentType = "application/json";

            JavaScriptSerializer serializer = new JavaScriptSerializer();
            string s = serializer.Serialize(p);
            textBox3.Text = s;

            string postData = "json=" + HttpUtility.UrlEncode(s);

            byte[] byteArray = Encoding.ASCII.GetBytes(postData);

            request.ContentLength = byteArray.Length;
            Stream dataStream = request.GetRequestStream();
            dataStream.Write(byteArray, 0, byteArray.Length);
            dataStream.Close ();

            WebResponse response = request.GetResponse();
            //textBox4.Text = (((HttpWebResponse)response).StatusDescription);
            dataStream = response.GetResponseStream ();

            StreamReader reader = new StreamReader(dataStream);
            string responseFromServer = reader.ReadToEnd ();
            textBox4.Text += responseFromServer;

            reader.Close ();
            dataStream.Close ();
            response.Close ();

服务器上的PHP代码：

$inbound = $_POST['json'];

// this strips out the \
$stripped = stripslashes($inbound);

$json_object = json_decode($stripped);
echo $json_object->{'firstName'};
echo $json_object->{'lastName'};
echo $json_object->{'email'};
echo $json_object->{'deviceUUID'};

Answer 1

你确定那里有那些斜杠吗？这是C＃编码字符串以供显示的调试器视图，但JavaScriptSerializer发出的实际值在标识符中没有任何斜杠。唯一被转义的是JSON值内容......

我发现这很容易使用：http://james.newtonking.com/archive/2008/02/11/linq-to-json-beta.aspx和http://james.newtonking.com/projects/json-net.aspx

Answer 3

好主意......我已经检查了VS，并在textBox3.Text = s上设置断点; 然后将鼠标悬停在上一行s上。它显示了这个：

s =“{\”firstName \“：\”Bill \“，\”lastName \“：\”Gates \“，\”email \“：\”asdf @ hotmail.com \“，\”deviceUUID \ “：\” ABCDEFGHIJKLMNOPQRSTUVWXYZ \ “}”

所以，我也检查了PHP方面：

$inbound = $_POST['json'];
var_dump($inbound);

的字符串（124） “{\” 名字\ “：\” 比尔\ “\ ”姓氏\“：\ ”盖茨\“，\ ”电子邮件\“：\ ”asdf@hotmail.com \“，\ ”deviceUUID \“：\” ABCDEFGHIJKLMNOPQRSTUVWXYZ \ “}”

Answer 4

JSON.NET非常棒且值得一试 - 它比JavaScriptSerializer更好地做了一些事情，但我知道JavaScriptSerializer（和任何其他JSON序列化程序）不会使用斜杠输出标识符。它是无效的JSON。

Answer 5

搞定了

有两个问题：

PHP服务器正在转发传入的数据，所以我不得不使用stripslashes。

http://nz.php.net/magic_quotes

同样在VS的房产上空盘旋，显示大幅削减但是

Debug.Write(s);

示：

[{"categoryid":"1","name":"funny","serverimageid":"1","dateuploaded":"2008-11-17 16:16:41","enabled":"\u0001"},{"categoryid":"2","name":"happy","serverimageid":"2","dateuploaded":"2008-11-17 16:17:00","enabled":"\u0001"},{"categoryid":"3","name":"sad","serverimageid":"3","dateuploaded":"2008-11-16 16:17:13","enabled":"\u0001"}]

谢谢大家。
