我一直在研究Walmart API,但是当我运行代码时,我一直收到401错误或500错误
public void post()
{
byte[] data = Encoding.ASCII.GetBytes(
$"username={user}&password={password}");
HttpWebRequest request = (HttpWebRequest)WebRequest.Create("https://marketplace.walmartapis.com/v2/feeds?feedType=item");
request.Method = "POST";
request.Accept = "application/xml;";
request.ContentLength = data.Length;
request.Headers.Add("WM_SVC.NAME", "Walmart Marketplace");
request.Headers.Add(authId);
request.Headers.Add("WM_CONSUMER.ID", user);
request.Headers.Add( time);
request.Headers.Add(CorId);
using (Stream stream = request.GetRequestStream ())
{
stream.Write(data , 0, data.Length);
}
string responseContent = null;
using (WebResponse response = request.GetResponse())
{
using (Stream stream = response.GetResponseStream())
{
using (StreamReader sr99 = new StreamReader(stream))
{
responseContent = sr99.ReadToEnd();
}
}
}
MessageBox.Show(responseContent);
}
其中authID是由walmart提供的jar文件生成的签名 时间也是从jar文件生成的 CorID是随机生成的数字 而user是用户ID。
这是描述标头参数的链接。我错过了标题中的内容吗?
答案 0 :(得分:0)
您的请求存在多个问题。首先,您要提交一个feed,但是当它应该是multipart / form-data请求时,将它作为application / xml发送。除此之外,您的标题没有正确设置,目前使用C#向Walmart提交multipart / form-data请求时存在一个主要问题。我没有看到任何人通过C#成功向沃尔玛发送Feed的帖子。我目前正在使用C#执行一个批处理文件,然后触发一个能够发送multipart / form-data请求的Walmart Java SDK的修改版本。
以下的回复是针对除Feed之外的任何请求。我将从下面列出的示例开始,以熟悉您需要如何设置标头。这适用于大多数Walmart接口,但如果请求是feed样式请求,您将需要为multipart / form-data问题提出更好的解决方案,使用Java SDK或等待C#SDK。如果有人读到这个并且有关如何通过C#提交Feed的更好答案,我很乐意听到它!
以下是有效的application / xml请求示例。
string timestamp = CurrentTimeMillis().ToString().Trim();
string query = @"orders/"+poID+"/acknowledge";
string request = v3BaseUrl + query; //Constructed URI
string stringToSign = consumerId + "\n" +
request.Trim() + "\n" +
"POST" + "\n" +
timestamp + "\n";
string signedString = signData(stringToSign); //Your signed string
HttpWebRequest webRequest = (HttpWebRequest)WebRequest.Create(request);
webRequest.Accept = "application/xml";
webRequest.ContentType = "application/xml";
webRequest.Method = "POST";
webRequest.Headers.Add("WM_SVC.NAME", "Walmart Marketplace");
webRequest.Headers.Add("WM_SEC.AUTH_SIGNATURE", signedString);
webRequest.Headers.Add("WM_CONSUMER.ID", consumerId);
webRequest.Headers.Add("WM_SEC.TIMESTAMP", timestamp.ToString().Trim());
webRequest.Headers.Add("WM_QOS.CORRELATION_ID", Guid.NewGuid().ToString());
webRequest.Headers.Add("WM_CONSUMER.CHANNEL.TYPE", channelType);
webRequest.ContentLength = 0;
webRequest.Timeout = Timeout.Infinite;
webRequest.KeepAlive = true;
using (HttpWebResponse response = (HttpWebResponse)webRequest.GetResponse())
{
if (response.StatusCode == HttpStatusCode.OK)
{
success = true;
}
}
