我正在尝试将一个工作的postman POST调用实现到一个c#控制台应用程序,它正在给我:禁止403。 它正在调用API并且正在上传CSV文件。 这是邮递员的工作电话:

postman part 1

postmnan part2 我正在尝试几种选择。我已经实现了这个代码禁止403:

    HttpClient c = new HttpClient();
    var fileContent = new ByteArrayContent(System.IO.File.ReadAllBytes(@"C:\test7.csv"));
    fileContent.Headers.ContentDisposition = new ContentDispositionHeaderValue("attachment")
    {
        FileName = "test7.csv"
    };
    fileContent.Headers.ContentType = MediaTypeHeaderValue.Parse("text/csv");

      var parameters = new Dictionary<string, string>
    {
        { "secret", "mypassword" }
    };

    HttpContent DictionaryItems = new FormUrlEncodedContent(parameters);

    MultipartContent content = new MultipartContent();
    //content.Add(formData);
    content.Add(DictionaryItems);
    content.Add(fileContent);
    c.DefaultRequestHeaders.Accept.Add(new MediaTypeWithQualityHeaderValue("application/x-www-form-urlencoded"));
    var resultado = c.PostAsync("https://www.apiurl,com", content).Result;

我认为我没有把秘密(密码)放在正确的位置。 有什么帮助吗?

答案 0 :(得分:-1)

我得到了答案。这里:

        FileStream stream = File.OpenRead(@"C:\test7.csv");
        byte[] fileBytes = new byte[stream.Length];
        stream.Read(fileBytes, 0, fileBytes.Length);
        stream.Close();
        var byteArrayContent = new ByteArrayContent(fileBytes);
        byteArrayContent.Headers.ContentType = MediaTypeHeaderValue.Parse("text/csv");
        HttpClient httpClient = new HttpClient();
        MultipartFormDataContent form = new MultipartFormDataContent();

        form.Add(new StringContent("mypassword"), "secret");
        form.Add(byteArrayContent, "file", "testT.csv");
        HttpResponseMessage response = httpClient.PostAsync("https://www.apiurl.com", form).Result;
        httpClient.Dispose();
