iPhone：如何使用 NSURLCredential 获得 HTTPS Web 服务的基本身份验证

发布于 2024-08-23 07:16:28 字数 1229 浏览 10 评论 0原文

我正在尝试使用基本身份验证调用 https Web 服务（RESTful）。如果我将凭据放在 url 本身中，效果很好，但我宁愿将其添加到请求中，这样密码就不会出现，例如在异常中。

我正在使用以下代码：

    NSURLCredential *credential = [NSURLCredential credentialWithUser:@"myuser"
                                                             password:@"mypassword"
                                                          persistence:NSURLCredentialPersistenceForSession];

    NSURLProtectionSpace *protectionSpace = [[NSURLProtectionSpace alloc]
                                             initWithHost:@"example.com"
                                             port:443
                                             protocol:@"https"
                                             realm:nil
                                             authenticationMethod:NSURLAuthenticationMethodHTTPBasic];


    [[NSURLCredentialStorage sharedCredentialStorage]  setDefaultCredential:credential
                                                        forProtectionSpace:protectionSpace];

    NSURLConnection *theConnection = [NSURLConnection  connectionWithRequest:theRequest delegate:self];

但它不起作用。 didReceiveAuthenticationChallenge 委托方法被调用，我可以在其中添加凭据，但理想情况下我会随请求一起发送它。

有什么想法吗？

I am trying to call an https web service (RESTful) using basic authentication.
It works fine if I put the credentials in the url itself but I would rather add it to the request so that the password does not appear, for instance in an exception.

I am using the following code:

    NSURLCredential *credential = [NSURLCredential credentialWithUser:@"myuser"
                                                             password:@"mypassword"
                                                          persistence:NSURLCredentialPersistenceForSession];

    NSURLProtectionSpace *protectionSpace = [[NSURLProtectionSpace alloc]
                                             initWithHost:@"example.com"
                                             port:443
                                             protocol:@"https"
                                             realm:nil
                                             authenticationMethod:NSURLAuthenticationMethodHTTPBasic];


    [[NSURLCredentialStorage sharedCredentialStorage]  setDefaultCredential:credential
                                                        forProtectionSpace:protectionSpace];

    NSURLConnection *theConnection = [NSURLConnection  connectionWithRequest:theRequest delegate:self];

but it does not work. The didReceiveAuthenticationChallenge delegate method gets called and I can add a credential there but ideally I would send it with the request.

Any ideas?

如果是基本身份验证，请尝试在标头中发送凭据。每次都对我有用。

用于在请求标头中发送用户名和密码

NSString *authString = [[NSString stringWithFormat:@"%@:%@", userName, password] stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding];
NSString *finalAuth = base64 of authString;

在您的请求中，添加包含字段名称 Authorization 和值 "Basic " + FinalAuth 的标头

Try sending the credentials in the header if it is basic authentication. Works for me every time.

For sending the username and password in the header of the request

NSString *authString = [[NSString stringWithFormat:@"%@:%@", userName, password] stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding];
NSString *finalAuth = base64 of authString;

In your request, add a header with the field name Authorization and value "Basic " + finalAuth

我错过了您使用 NSURLConnection 的最后一行代码。确保您的代表正在响应：

- (BOOL)connection:(NSURLConnection *)connection canAuthenticateAgainstProtectionSpace:(NSURLProtectionSpace *)protectionSpace

并且为您的保护空间返回“是”。

另外，请确保您的委托正在响应：

- (void)connection:(NSURLConnection *)connection didReceiveAuthenticationChallenge:(NSURLAuthenticationChallenge *)challenge

在这里，您可以将您创建的凭据分配给proposalCredential属性中的NSURLAuthenticationChallenge，以及将您的NSURLProtectionSpace实例分配给NSURLAuthenticationChallenge 的 protectedSpace 属性。

I missed that last line of code where you are using NSURLConnection. Make sure that your delegate is responding to :

- (BOOL)connection:(NSURLConnection *)connection canAuthenticateAgainstProtectionSpace:(NSURLProtectionSpace *)protectionSpace

And is returning YES for your protectionSpace.

Also, make sure that your delegate is responding to :

- (void)connection:(NSURLConnection *)connection didReceiveAuthenticationChallenge:(NSURLAuthenticationChallenge *)challenge

Here you can assign the credential that you created to the NSURLAuthenticationChallenge in the proposedCredential property, as well as your NSURLProtectionSpace instance into the protectionSpace property of the NSURLAuthenticationChallenge.
