我正在露天开发基于REST的网络服务,用于数据传输和扩展。想知道我可以通过REST协议发送/获取的最大数据量是多少?
任何参考都会非常有用。
问候。
答案 0 :(得分:2)
最大数据量大到2147000000.这就是为什么如果您的数据足够大,建议将其流式传输到您的REST服务。这是一个例子。
发件人/上传者应用程序或客户
var sb = new StringBuilder();
sb.Append("Just test data. You can send large one also");
var postData = sb.ToString();
var url = "REST Post method example http://localhost:2520/DataServices/TestPost";
var memoryStream = new MemoryStream();
var dataContractSerializer = new DataContractSerializer(typeof(string));
dataContractSerializer.WriteObject(memoryStream, postData);
var xmlData = Encoding.UTF8.GetString(memoryStream.ToArray(), 0, (int)memoryStream.Length);
var client = new WebClient();
client.UploadStringAsync(new Uri(url), "POST", "");
client.Headers["Content-Type"] = "text/xml";
client.UploadStringCompleted += (s, ea) =>
{
if (ea.Error != null) Console.WriteLine("An error has occured while processing your request");
var doc = XDocument.Parse(ea.Result);
if (doc.Root != null) Console.WriteLine(doc.Root.Value);
if (doc.Root != null && doc.Root.Value.Contains("1"))
{
string test = "test";
}
};
REST服务方法
[WebInvoke(UriTemplate = "TestPost", Method = "POST", BodyStyle = WebMessageBodyStyle.WrappedRequest, RequestFormat = WebMessageFormat.Xml)]
public string Publish(string market,string sportId, Stream streamdata)
{
var reader = new StreamReader(streamdata);
var res = reader.ReadToEnd();
reader.Close();
reader.Dispose();
}
不要忘记在REST服务配置文件中放置以下配置设置如果没有这个设置会导致错误
<system.web>
<compilation debug="true" targetFramework="4.0" />
<httpRuntime maxRequestLength="2147000000" maxQueryStringLength="2097151" maxUrlLength="2097151"/>
</system.web>
<system.webServer>
........
</system.webServer>
