grant_type参数无效或在获取新访问令牌以处理过期的访问令牌时缺少参数

Question

我在使用Box获取新访问令牌时出错。

{"error":"invalid_request","error_description":"Invalid grant_type parameter or parameter missing"}

下面是获取新框访问令牌的文档。

curl https://www.box.com/api/oauth2/token -d 'grant_type=refresh_token&refresh_token={valid refresh token}&client_id={your_client_id}&client_secret={your_client_secret}' -X POST

我将grant_type和refresh_token作为相同的刷新令牌传递。如果两者都不同，那么我需要为grant_type和refresh_token传递值。

我有办法了,

 NSString* refresh =your refresh token;

NSString* clientId =[NSString stringWithFormat:@"%@",[BoxSDK sharedSDK].OAuth2Session.clientID];
NSString* clientSecret =[NSString stringWithFormat:@"%@", [BoxSDK sharedSDK].OAuth2Session.clientSecret];

ASIFormDataRequest *postParams = [ASIFormDataRequest requestWithURL:[NSURL URLWithString:@"https://www.box.com/api/oauth2/token?"]];

[postParams setRequestMethod:@"POST"];

[postParams setPostValue:@"refresh_token" forKey:@"grant_type"];
[postParams setPostValue:refresh forKey:@"refresh_token"];
[postParams setPostValue:clientId forKey:@"client_id"];
[postParams setPostValue:clientSecret forKey:@"client_secret"];

[postParams startAsynchronous];
postParams.delegate = self ;
postParams.userInfo = [NSDictionary dictionaryWithObject:@"accessToken" forKey:@"id"];

NSLog(@"Url is ---> %@",postParams.url);
