405 (不允许使用的方法)2/4

Question

updateUserDetails(ename,ejobtitle,edept,eunit,equal,eaqser,empid)
{

  let url = GlobalVariable.BASE_API_URL + "api/updateUserProfile";    
  let headers = new Headers({'Content-Type':'application/json'});
  let options = new RequestOptions({headers:headers});
  const body = 
  {"empno":empid,"name":ename,"jobtitle":ejobtitle,"dept":edept,"unit":eunit,"qualification":equal,"aqinservice":eaqser}

  return this.http.post(url,body,options)
  .map(resp=>resp.json());    

}

API接口

[Route("api/updateUserProfile")]
    [HttpPost]       
    public HttpResponseMessage updateUserProfile(HttpResponseMessage Req)
    {
        try
        {
            string postData = new System.IO.StreamReader(HttpContext.Current.Request.InputStream).ReadToEnd();

            UserMaster.Instance.UpdateUserProfile(postData);
            var JSONString = new StringBuilder();
            JSONString.Append("{");
            JSONString.Append("\"status" + "\":" + "\"ok" + "\",");
            JSONString.Append("\"message" + "\":" + "\"Record Updated successfilly." + "\"");              
            JSONString.Append("}");
            var response = Request.CreateResponse(HttpStatusCode.OK);
            response.Content = new StringContent(JSONString.ToString(), System.Text.Encoding.UTF8, "application/json");
            return response;

        }
}

我得到了角4- 405的误差(方法不允许)

但它在Fiddler中运作得很好。

Answer 1

有很多方法可以这样做，其中之一就是可以使用Object.keys()和Object.values()方法从数据中提取键和值。

      keys:Array<String>;
      values:Array<String>;
    item={"em id":"101","name":"ABC","role":"admin"};

 myFun()
    {
     this.keys=Object.keys(this.item);
      this.values=Object.values(this.item);
    }

Answer 2

使用该对象最简单的方法就是给它命名并访问它的属性。

例如，

item = {"em id":"101","name":"ABC","role":"admin"}; 

然后像这样用它，

console.log("em_id is " + item.em_id + "name is " + item.name + "role is" + item.role );

但如果你真的想把它存储在变量里然后用同样的方式去做，

let em_id = item.em_id;
let name = item.name;
let role = item.role;

Answer 3

问题是“飞行前请求”。将OPTIONS方法添加到api中，然后只返回就可以了。
