403在C#中使用Webrequest时禁止出现错误,但在postman中有效
我有一个授权码,在调用api时,我需要将它和一些头值一起传递到主体中。当从邮递员那里尝试同样的方法时,它工作正常,但是C#Webclient抛出403错误 代码如下:- 公共字符串GetResponse(字符串AuthCode) {403在C#中使用Webrequest时禁止出现错误,但在postman中有效,c#,curl,asp.net-web-api,postman,C#,Curl,Asp.net Web Api,Postman,我有一个授权码,在调用api时,我需要将它和一些头值一起传递到主体中。当从邮递员那里尝试同样的方法时,它工作正常,但是C#Webclient抛出403错误 代码如下:- 公共字符串GetResponse(字符串AuthCode) { string url = "https://example.com//openam/oauth2/access_token?grant_type=authorization_code&realm=/cbpgatqa"; Uri uri = n

邮递员卷曲命令:-
从curl请求生成:

我想不出这个问题。有人能帮我解决这个问题吗?使用RestSharp并传递正确的headers值
var client = new RestClient("https://example.com/openam/oauth2/access_token?grant_type=authorization_code&realm=/cbpgatqa");
var request = new RestRequest(Method.POST);
request.AddHeader("Content-Type", "application/x-www-form-urlencoded");
request.AddHeader("Cache-Control", "no-cache");
request.AddHeader("Authorization", "Basic MzE4OGQwYjQtZTRlOC00MTZjLTg5NjAtZDNlYWFhMmNjY2IxOkx3NiVBa0x4NWtPM01rJTJ5RWwxbW1jR0ZYZmhTQmk1NHhIRCpzNiUyVUd5WXN0MCNVbyNMNWQhcVlpZE93djc=");
request.AddParameter("undefined", "code=" + AuthCode + "&redirect_uri=http%3A%2F%2Flocalhost%3A8080", ParameterType.RequestBody);
IRestResponse response = client.Execute(request);
using (var ms = new MemoryStream(Encoding.Unicode.GetBytes(response.Content)))
{
// Deserialization from JSON
DataContractJsonSerializer deserializer = new DataContractJsonSerializer(typeof(Token));
Token token = (Token)deserializer.ReadObject(ms);
return userinfo= GetuserInfo(token.id_token);
}
postData不是表单数据编码。请注意文章正文与curl的区别:
redirect\u uri=http%3A%2F%2folocalhost%3A8080%2F
尝试对redirect\u URl进行编码,但得到了相同的禁止错误:(也许您可以使用类似Fiddler的东西来显示这两种请求的完整示例?我还注意到,重定向uri在您的curl请求中以/
结尾,但在您的代码中没有。如果重定向uri有任何问题,它将给出如下错误:-{“error\u description”:“提供的重定向URI与预先注册的值不匹配。”,“错误”:“重定向URI不匹配”}我在postman中尝试过
