Question

net wcf webinvoke 怎么post请求的json

Answer 1

测试实体类:(需要在客户端和服务端建了有相同字段名称的实体)

public class CompositeType
{
public CompositeType()
{
SubCompositeTypes = new List<SubCompositeType>() { new SubCompositeType() };
}
public bool BoolValue { get; set; }
public string StringValue { get; set; }
public List<SubCompositeType> SubCompositeTypes
{
get;
set;
}
}
public class SubCompositeType
{
bool boolValue = true;
string stringValue = "Hello ";
public bool BoolValue
{
get { return boolValue; }
set { boolValue = value; }
}
public string StringValue
{
get { return stringValue; }
set { stringValue = value; }
}
}

客户端请求代码:

#region JosnPost
CompositeType compositeType = new CompositeType
{
StringValue = "1",
BoolValue = false
};

DataContractJsonSerializer dcSerializer = new DataContractJsonSerializer(typeof(CompositeType));

MemoryStream stream = new MemoryStream();

dcSerializer.WriteObject(stream, compositeType);

string data = Encoding.UTF8.GetString(stream.ToArray(), 0, (int)stream.Length);

//HttpClient client = new HttpClient();

//client.DefaultRequestHeaders.Accept.Add(new MediaTypeWithQualityHeaderValue("application/json"));

string link = "http:// localhost:1766/Service1.svc/CreateUser";

//HttpResponseMessage respondse = await client.PostAsync(link, new StringContent(data));

//string dataWithJason = await respondse.Content.ReadAsStringAsync();

var request = (HttpWebRequest)WebRequest.Create(new Uri(link));
request.ContentType = "application/json";
request.Method = "POST";

using (var requestStream = await request.GetRequestStreamAsync())
{
var writer = new StreamWriter(requestStream);
writer.Write(data);
writer.Flush();
}

using (var resp = await request.GetResponseAsync())
{
using (var responseStream = resp.GetResponseStream())
{
var reader = new StreamReader(responseStream);
var result = reader.ReadToEnd();
}
}
