在下面的代码中,始终get model为null,但对于[frombody] string参数却不存在 在WebApiConfig中设置cors
var cors = new EnableCorsAttribute(origins:"*",methods: "*", headers: "*");
config.EnableCors(cors);
//控制器
[Route("SaveorUpdateCategory")]
[HttpPost]
public IHttpActionResult SaveorUpdateCategory(ModelCategory model)
{
string res = objcate.SaveorUpdateCategory(model);
return Ok(res);
}
//角度服务
SaveorUpdateCategory( model: any): Observable<any> {
this.headers= new Headers({ 'Content-Type': 'application/json' })
this.options = new RequestOptions({ headers: this.headers });
let body = JSON.stringify(model);
return this._http.post(this.BaseURL+"Category/SaveorUpdateCategory", model, this.options)
.map((response: Response) => <any>response.json())
.catch(this.handleError);
}
模型样本为{categry:'Test',Id:'1'} 当传递单个变量获取值时,但模型始终为空
将cors安装为Microsoft.AspNet.WebApi.Cors安装包

使用FromBody如下更改您的Web api方法,
public void Disconnect([FromBody] ModelCategory model) { }
