我对邮递员和 c# 代码有疑问。我有两次对 API 的 post 调用,最后必须回调到另一个 API(webhook)。
我尝试通过 Postman 启动这两个调用,并且我确实获得了正确的回调响应。我的问题是,当我使用此代码时,我没有任何回调响应,但我从我调用的服务器获取了 200 条消息。我发送的 http post 调用的所有实现都遇到了同样的问题,并遇到了同样的问题。
public static void Main(string[] args)
{
// first call
var client = new RestClient("http://xxxxxxx/emails/attachments/");
client.Timeout = -1;
var request = new RestRequest(Method.POST);
request.AddHeader("Authorization",
"Bearer theToken");
request.AddFile("attachment",
"C:/Users/..../pdf.pdf");
IRestResponse response = client.Execute(request);
Console.WriteLine(response.Content);
var attachmentId = response.Content;
// second call
client = new RestClient("http://xxxxxxx/emails/");
client.Timeout = -1;
request = new RestRequest(Method.POST);
request.AddHeader("Accept", "application/json");
request.AddHeader("Content-Type", "application/json");
request.AddHeader("Authorization",
"Bearer theToken");
request.AddParameter("application/json",
"{\r\n \"subject\": \"email with attachment\",\r\n \"body\": \"Hi !!!l\\r\\n\",\r\n \"received_on\": \"2021-05-24T14:07:01.5874416+02:00\",\r\n \"author\": {\r\n \"name\": \"dvera@mymail.fr\",\r\n \"smtp_address\": \"\"\r\n },\r\n \"sender\": {\r\n \"name\": \"dvera@mymail.fr\",\r\n \"smtp_address\": \"\"\r\n },\r\n \"to\": [\r\n {\r\n \"name\": \"dvera@mymail.fr\",\r\n \"smtp_address\": \"\"\r\n }\r\n ],\r\n \"cc\": [\r\n {\r\n \"name\": \"\",\r\n \"smtp_address\": \"\"\r\n }\r\n ],\r\n \"attachments\": [\r\n " +
attachmentId + "\r\n ]\r\n}\r\n", ParameterType.RequestBody);
response = client.Execute(request);
Console.WriteLine(response.Content);
}
}
知道出了什么问题吗?奇怪的是,我每次拨打电话都会收到 200 条回复。
答案 0 :(得分:1)
我用这段代码解决了我的问题:
using (var client = new HttpClient())
{
using (var form = new MultipartFormDataContent())
{
client.DefaultRequestHeaders.Add("Authorization", "Bearer " + token);
var file = File.OpenRead(attachmentPath);
byte[] fileBytes = new byte[file.Length];
form.Add(new ByteArrayContent(fileBytes, 0, fileBytes.Length), "attachment", Path.GetFileName(attachmentPath));
HttpResponseMessage response = await client.PostAsync(url, form);
response.EnsureSuccessStatusCode();
var output = await response.Content.ReadAsStringAsync();
PostEmailAttachmentResponse returnValue = new PostEmailAttachmentResponse();
returnValue.Id = Int32.Parse(output);
return returnValue;
}
}
当我发送附件时,我以前的代码没有返回错误消息。服务器端出现问题,没有返回错误。
