[英]How to make an Okhttp Request with “Content-type:application/x-www-form-urlencoded”?
[英]How to write controller class to allow content-type: application/json and application/x-www-form-urlencoded
我正在將請求作為內容類型發送到控制器類請求:application / json和application / x-www-form-urlencoded格式應該同時允許兩種類型。
但是,當我使用請求類型作為應用程序/ x-www-form-urlencoded時,它可以工作,但是當我使用請求應用程序/ json時,此代碼不起作用,它給出的響應狀態為400。 如何解決這個問題。
您需要為請求的“ Content-Type”標頭使用“ consumes”注釋元素,並為請求的“ Accept”標頭使用“ produces”注釋元素:
@RequestMapping(value = "/home",
method = RequestMethod.POST,
consumes = {"application/json", "application/x-www-form-urlencoded"},
produces = "application/json")
這些RequestMapping元素可用於Spring4。如果使用Spring 2,則需要使用“ params”元素,而不是“ consumes”和“ produces”元素:
@RequestMapping(value = "/home",
method = RequestMethod.POST,
params = {"content-type=application/json",
"content-type=application/x-www-form-urlencoded",
"Accept=application/json"})
使用Oauth2令牌
: public void login()
{
string userName = "abc@mailinator.com";
string password = "Pass@123";
//var registerResult = Register(userName, password);
//Console.WriteLine("Registration Status Code: {0}", registerResult);
string token = GetToken(userName, password);
Console.WriteLine("");
Console.WriteLine("Access Token:");
Console.WriteLine(token);
Dictionary<string, string> tokenDic = GetTokenDictionary(token);
GetUserInfo(tokenDic["access_token"]);
}
private const string baseUrl = "http://localhost/WebApplication4";
static string GetToken(string userName, string password)
{
var pairs = new List<KeyValuePair<string, string>>
{
new KeyValuePair<string, string>( "grant_type", "password" ),
new KeyValuePair<string, string>( "userName", userName ),
new KeyValuePair<string, string> ( "password", password )
};
var content = new FormUrlEncodedContent(pairs);
using (var client = new HttpClient())
{
var response = client.PostAsync(baseUrl + "/Token", content).Result;
return response.Content.ReadAsStringAsync().Result;
}
}
static Dictionary<string, string> GetTokenDictionary(string token)
{
// Deserialize the JSON into a Dictionary<string, string>
Dictionary<string, string> tokenDictionary = JsonConvert.DeserializeObject<Dictionary<string, string>>(token);
return tokenDictionary;
}
static HttpClient CreateClient(string accessToken = "")
{
var client = new HttpClient();
if (!string.IsNullOrWhiteSpace(accessToken))
{
client.DefaultRequestHeaders.Authorization =
new System.Net.Http.Headers.AuthenticationHeaderValue("Bearer", accessToken);
}
return client;
}
static string GetUserInfo(string token)
{
using (var client = CreateClient(token))
{
var response = client.GetAsync(baseUrl + "/api/Account/UserInfo").Result;
return response.Content.ReadAsStringAsync().Result;
}
}
<form id="form1" action="@ViewBag.Action" method="POST">
<div>
Access Token<br />
<input id="AccessToken" name="AccessToken" width="604" type="text" value="@ViewBag.AccessToken" />
<input id="Authorize" name="submit.Authorize" value="Authorize" type="submit" />
<br />
<br />
Refresh Tokensh Token<br />
<input id="RefreshToken" name="RefreshToken" width="604" type="text" value="@ViewBag.RefreshToken" />

<br />
<br />
<input id="CallApi" name="submit.CallApi" value="Access Protected Resource API" type="submit" />
</div>
<div>
@ViewBag.ApiResponse

</form>
獲取垃圾令牌
: public ActionResult Index()
{
ViewBag.AccessToken = Request.Form["AccessToken"] ?? "";
ViewBag.RefreshToken = Request.Form["RefreshToken"] ?? "";
ViewBag.Action = "";
ViewBag.ApiResponse = "";
InitializeWebServerClient();
var accessToken = Request.Form["AccessToken"];
if (string.IsNullOrEmpty(accessToken))
{
var authorizationState = _webServerClient.ProcessUserAuthorization(Request);
if (authorizationState != null)
{
ViewBag.AccessToken = authorizationState.AccessToken;
ViewBag.RefreshToken = authorizationState.RefreshToken;
ViewBag.Action = Request.Path;
}
}
if (!string.IsNullOrEmpty(Request.Form.Get("submit.Authorize")))
{
var userAuthorization = _webServerClient.PrepareRequestUserAuthorization(new[] { "bio", "notes" });
userAuthorization.Send(HttpContext);
Response.End();
}
else if (!string.IsNullOrEmpty(Request.Form.Get("submit.Refresh")))
{
var state = new AuthorizationState
{
AccessToken = Request.Form["AccessToken"],
RefreshToken = Request.Form["RefreshToken"]
};
if (_webServerClient.RefreshAuthorization(state))
{
ViewBag.AccessToken = state.AccessToken;
ViewBag.RefreshToken = state.RefreshToken;
}
}
else if (!string.IsNullOrEmpty(Request.Form.Get("submit.CallApi")))
{
var resourceServerUri = new Uri(Paths.ResourceServerBaseAddress);
var client = new HttpClient(_webServerClient.CreateAuthorizingHandler(accessToken));
var body = client.GetStringAsync(new Uri(resourceServerUri, Paths.MePath)).Result;
ViewBag.ApiResponse = body;
}
return View();
}
private void InitializeWebServerClient()
{
var authorizationServerUri = new Uri(Paths.AuthorizationServerBaseAddress);
var authorizationServer = new AuthorizationServerDescription
{
AuthorizationEndpoint = new Uri(authorizationServerUri, Paths.AuthorizePath),
TokenEndpoint = new Uri(authorizationServerUri, Paths.TokenPath)
};
_webServerClient = new WebServerClient(authorizationServer, Clients.Client1.Id, Clients.Client1.Secret);
}
}
您可以在@RequestMapping和xml中的ViewResolver中定義消耗屬性。 下面:
