Unity:在Unity3D中使用HTTP PUT

Question

我是Unity的新手,在Unity中遇到RESTFul的一些问题.我想使用HTTP PUT更新服务器上的一些数据,但正如我在搜索网络时收到的那样,Unity中的WWWW类不支持HTTP PUT.我还尝试了一些与HTTP PUT相关的HttpWebRequest示例,但总是收到错误代码400:错误请求.

我怎么解决这个问题？我是否必须在更新时列出所有键值对,或者只需要列出我想要更改值的对？

如果您不是在寻找第三方插件并假设您的服务器支持它,那么您可以使用的一种方法是"X-HTTP-Method-Override"HTTP标头.您的客户端通过POST将数据发送到服务器,但服务器将此处理为X-HTTP-Method-Override标头中的值(例如PUT).

我之前使用过这个,效果很好,我们的服务器支持它.在Unity3d中使用它的一个例子是:

string url = "http://yourserver.com/endpoint";
byte[] body = Encoding.UTF8.GetBytes(json);    

Dictionary<string, string> headers = new Dictionary<string, string>();
headers.Add( "Content-Type", "application/json" );
headers.Add( "X-HTTP-Method-Override", "PUT" );
WWW www = new WWW(url, body, headers);

我使用 HttpWebRequest 通过以下代码使其工作

void updatePlayer(){
    var httpWebRequest = (HttpWebRequest)WebRequest.Create("http://yourAPIUrl");
    httpWebRequest.ContentType = "text/json";
    httpWebRequest.Method = "PUT";

    using (var streamWriter = new StreamWriter(httpWebRequest.GetRequestStream()))
    {
        string json = "{" +
            "'ID': '100'," +
            "'ClubName': 'DEF'," +
            "'Number': 102," +
            "'Name': 'AnNT'," +
            "'Position': 'GK'," +
            "'DateOfBirth': '2010-06-15T00:00:00'," +
            "'PlaceOfBirth': 'Hanoi'," +
            "'Weight': 55," +
            "'Height': 1.55," +
            "'Description': 'des'," +
            "'ImageLink': 'annt.png'," +
            "'Status': false," +
            "'Age': '12'" +
            "}";            
        streamWriter.Write(json);
    }
    var httpResponse = (HttpWebResponse)httpWebRequest.GetResponse();
    using (var streamReader = new StreamReader(httpResponse.GetResponseStream()))
    {
        var responseText = streamReader.ReadToEnd();
        //Now you have your response.
        //or false depending on information in the response
        Debug.Log(responseText);            
    }   
}
