我试图从.NET Core MVC应用程序进行简单的API调用:
using (var client = new HttpClient())
{
client.BaseAddress = new Uri("http://localhost:49897");
var response = client.GetAsync("some-route").Result;
var dataString = response.Content.ReadAsStringAsync().Result; // Unexpected data here. See below.
[...] // deserialize dataString
}
client.GetAsync(route)
成功点击API动作方法,最终会执行此操作:
public HttpResponseMessage Get([FromUri] BindingModel bindingModel)
{
List<SomeModel> resultObjects;
[...] // populate resultObjects with data
return Request.CreateResponse(HttpStatusCode.OK, resultObjects, new JsonMediaTypeFormatter());
}
但dataString
最终等于此:
"{\"version\":{\"major\":1,\"minor\":1,\"build\":-1,\"revision\":-1,\"majorRevision\":-1,\"minorRevision\":-1},\"content\":{\"objectType\":\"System.Object, System.Private.CoreLib, Version=4.0.0.0, Culture=neutral, PublicKeyToken=7cec85d7bea7798e\",\"formatter\":{\"indent\":false,\"serializerSettings\":{\"referenceLoopHandling\":0,\"missingMemberHandling\":0,\"objectCreationHandling\":0,\"nullValueHandling\":0,\"defaultValueHandling\":0,\"converters\":[],\"preserveReferencesHandling\":0,\"typeNameHandling\":0,\"metadataPropertyHandling\":0,\"typeNameAssemblyFormat\":0,\"typeNameAssemblyFormatHandling\":0,\"constructorHandling\":0,\"contractResolver\":null,\"equalityComparer\":null,\"referenceResolver\":null,\"referenceResolverProvider\":null,\"traceWriter\":null,\"binder\":null,\"serializationBinder\":null,\"error\":null,\"context\":{},\"dateFormatString\":\"yyyy'-'MM'-'dd'T'HH':'mm':'ss.FFFFFFFK\",\"maxDepth\":null,\"formatting\":0,\"dateFormatHandling\":0,\"dateTimeZoneHandling\":3,\"dateParseHandling\":1,\"floatFormatHandling\":0,\"floatParseHandling\":0,\"stringEscapeHandling\":0,\"culture\":{}}}}}"
或者,以JSON格式:
{
version: {
major: 1,
minor: 1,
[...]
},
content: {
objectType: "System.Object, System.Private.CoreLib, Version=4.0.0.0, Culture=neutral, PublicKeyToken=7cec85d7bea7798e"
formatter: {
indent: false,
serializerSettings: {
[...]
}
}
}
}
我的模型列表根本就没有。
究竟要归还什么,以及为什么我的回复模型列表不是?我查看了几个在线资源,我似乎正在按照他们展示的方式做事。这是一个非常棒的API调用,所以我不确定它是怎么回事。

究竟是什么回复,为什么我的回复中的模型列表不是?
您正在服务器端混合使用Web API 2和Core。您看到的数据是序列化的HttpResponseMessage
,它不再是框架的一部分,因此在从操作返回时它将其视为普通对象。
您需要使用.Net-Core的新语法
public IActionResult Get([FromUri] BindingModel bindingModel) {
List<SomeModel> resultObjects;
[...] // populate resultObjects with data
return Ok(resultObjects);
}
