Asp.net核心Webapi从Angular4应用获取空值 [英] Asp.net core webapi getting null value posted from Angular4 app
问题描述
我是Angular4
的新手,可以快速交付东西,所以没有时间充分学习它,所以请原谅我的问题:
I am new to Angular4
and in a situation to deliver the stuff quickly so have no time to learn it thoroughly so pardon if my question seems childish:
在我的Asp.Net Web API
中,我有Confirmemail API
,必须从Angular4应用程序中调用它,如下所示:
From my Asp.Net Web API
I have Confirmemail API
which has to be called from Angular4 application, looks like this:
Asp.net WebApi:
[HttpPost]
public async Task<object>ConfirmEmail([FromBody] string userid,[FromBody] string code)
{
}
在Angular4 Service API中:
ConfirmEmail(userid,code)
{
let url =`api/account/ConfirmEmail`;
let data= `userid=${userid}&code=${code}`;
console.log(data);
return this.http.post(url,data);
}
在这里,我在console.log中检查了数据是否正确,但是在webapi端,我发现这些字符串为null.我尝试删除[FromBody],但对我而言无效.
Here, I checked in console.log the data is coming properly, but at the webapi side I am finding these strings null. I tried removing [FromBody] but it didn't worked with me.
我真的不知道所缺少的是什么,准备所有这些东西几乎是一天,但没有取得任何成功.你们有什么解决方法吗?
I am really clueless what is missing, it is almost one day preparing all these things but have not got any success. Do you guys have any workaround?
推荐答案
对于从角度应用程序到API
的post
数据,请尝试在角度中进行以下操作:
For post
data to your API
from angular app try this in angular:
let url ="api/account/ConfirmEmail";
var userInfo = { "userid":userid, "code":code }
let content = JSON.stringify(userInfo);
let headers = new HttpHeaders();
headers.set("Content-Type", "application/json");
return this.http.post(url, content, { headers: headers, responseType: 'text'});
,并在您的API
中,以接收您的请求正文并反序列化:
and in your API
for receive your request body and deserialize this:
[HttpPost]
public async Task<object>ConfirmEmail([FromBody] UserInfo userInfo)
{
}
Public Class UserInfo
{
public long userid {get; set;}
public long code {get; set;}
}
要在 url 中发送数据,您应使用http get
这样的方法:
For send your data in url you should use http get
method like this:
角度:
let Params = new HttpParams();
Params = Params.append("userid", userid);
Params = Params.append("code", code);
return this.http.get(url , { params: Params });
Web API:
[HttpGet]
public async Task<object>ConfirmEmail(string userid, string code)
{
}
