[英]ASP.Net Core Passing HttpRequestMessage Parameter always empty
There is something weird with the passing parameter. 传递参数有些奇怪。 The function is being called, I can debug it, but the request is always empty.
正在调用该函数,我可以对其进行调试,但请求始终为空。
[EnableCors("SiteCorsPolicy")]
[ApiController]
[Route("api/[controller]")]
public class LineBotController : ControllerBase
{
private LineMessagingClient _lineMessagingClient;
public LineBotController()
{
_lineMessagingClient = new LineMessagingClient(Config._Configuration["Line:ChannelAccessToken"]);
}
[HttpPost]
public async Task<HttpResponseMessage> Post(HttpRequestMessage request)
{
try
{
var events = await request.GetWebhookEventsAsync(Config._Configuration["Line:ChannelSecret"]);
var app = new LineBotApp(_lineMessagingClient);
await app.RunAsync(events);
}
catch (Exception e)
{
Helpers.Log.Create("ERROR! " + e.Message);
}
return request.CreateResponse(HttpStatusCode.OK);
}
}
Is the HttpRequestMessage suppose to get every data from the request? HttpRequestMessage是否假设从请求中获取每个数据?
Some example of calling it: 调用它的一些例子:
var data = {
'to': 'xxx',
'messages':[
{
"type": "text",
"text": "Hello, world1"
},
{
"type": "text",
"text": "Hello, world2"
}
]
};
$.ajax({
type: 'POST',
contentType: "application/json; charset=utf-8",
dataType: 'json',
async: false,
data: JSON.stringify({request: data}),
url: url,
authorization: 'Bearer {Key}',
success: function (success) {
var x = success;
},
error: function (error) {
var x = error;
}
});
the url: https://localhost/api/LineBot url: https:// localhost / api / LineBot
Asp.net core no longer uses HttpRequestMessage
or HttpResponseMessage
. Asp.net核心不再使用
HttpRequestMessage
或HttpResponseMessage
。 you would need to convert the code from the Github Repository for the WebhookRequestMessageHelper
您需要从Github存储库转换
WebhookRequestMessageHelper
的代码
https://github.com/pierre3/LineMessagingApi/blob/master/Line.Messaging/Webhooks/WebhookRequestMessageHelper.cs https://github.com/pierre3/LineMessagingApi/blob/master/Line.Messaging/Webhooks/WebhookRequestMessageHelper.cs
/// <summary>
/// Verify if the request is valid, then returns LINE Webhook events from the request
/// </summary>
/// <param name="request">HttpRequestMessage</param>
/// <param name="channelSecret">ChannelSecret</param>
/// <returns>List of WebhookEvent</returns>
public static async Task<IEnumerable<WebhookEvent>> GetWebhookEventsAsync(this HttpRequestMessage request, string channelSecret)
{
if (request == null) { throw new ArgumentNullException(nameof(request)); }
if (channelSecret == null) { throw new ArgumentNullException(nameof(channelSecret)); }
var content = await request.Content.ReadAsStringAsync();
var xLineSignature = request.Headers.GetValues("X-Line-Signature").FirstOrDefault();
if (string.IsNullOrEmpty(xLineSignature) || !VerifySignature(channelSecret, xLineSignature, content))
{
throw new InvalidSignatureException("Signature validation faild.");
}
return WebhookEventParser.Parse(content);
}
so that it will work in .net core. 这样它才能在.net核心中运行。
[HttpPost]
public async Task<IActionResult> Post([FromBody] string content) {
try {
var events = WebhookEventParser.Parse(content);
var app = new LineBotApp(_lineMessagingClient);
await app.RunAsync(events);
} catch (Exception e) {
Helpers.Log.Create("ERROR! " + e.Message);
}
return Ok();
}
This is meant to be a simplified example which does not verify signature. 这是一个不验证签名的简化示例。
