以下是创建客户端和POST对象的代码。我的理解是,设置AllowAutoRedirect = true将使客户端能够遵循重定向然后执行GET,并且我能够反序列化所述对象。到目前为止,我的测试证明是不成功的。有什么我可能会忽略的吗?
Web API端点:
public HttpResponseMessage Post([FromBody] Contact contact) {
try {
// Add user
...
var msg = Request.CreateResponse(HttpStatusCode.Created);
msg.Headers.Location = new Uri(Request.RequestUri + "/" + customer.Person.PersonID);
return msg;
} catch (ValidationException tve) {
var apiError = new ApiResponseMessage { Message = "Invalid contact" };
foreach (var message in FilterErrors(tve.Messages)) {
if (message.Contains("required", StringComparison.OrdinalIgnoreCase)) {
apiError.Errors.Add(new ApiErrorMessage {
Code = ErrorCode.RequiredPropertyNotProvided,
Message = message
});
} else {
apiError.Errors.Add(new ApiErrorMessage {
Code = ErrorCode.PropertyNotValid,
Message = message
});
}
}
return Request.CreateResponse(HttpStatusCode.BadRequest, apiError);
}
}
客户代码:
public Contact Post(Contact contact)
{
try
{
var handler = new HttpClientHandler { AllowAutoRedirect = true};
using (var client = new HttpClient(handler))
{
client.BaseAddress = new Uri(APIServer);
client.DefaultRequestHeaders.Accept.Add(new MediaTypeWithQualityHeaderValue("application/json"));
client.DefaultRequestHeaders.Add("X-ApiKey", APIKey.ToString());
var response = client.PostAsJsonAsync("v1/Contacts", contact).Result;
if (response.IsSuccessStatusCode)
{
Log.DebugFormat("Post v1/Contacts => {0} ({1})", response.StatusCode, response.ReasonPhrase);
var result = JsonConvert.DeserializeObject<Contact>(response.Content.ReadAsStringAsync().Result);
// This object is null
}
else
{
Log.ErrorFormat("Post v1/Contacts => {0} ({1})", response.StatusCode, response.ReasonPhrase);
var result = JsonConvert.DeserializeObject<ApiMessageResponse>(
response.Content.ReadAsStringAsync().Result);
}
}
}
catch (Exception exception)
{
Log.Error(exception);
}
return null;
}
Wireshark日志。
POST / v1 / Contacts HTTP / 1.1(application / json) HTTP / 1.1 201已创建 地点:http://api01.example.com/v1/Contacts/10135052
就是这样,就我所知,没有GET(http://api01.example.com/v1/Contacts/10135052)。

从您添加的日志跟踪中,看起来POST的响应是201(已创建);没有重定向。响应确实包含一个URL(在标题或正文中,很难说)但它并不意味着什么特别的。您的客户端需要解析URL本身并明确发出后续GET请求。
