我需要从受密码保护的URL解析xml文件,我尝试了以下操作
NSURLCredential *credential = [NSURLCredential credentialWithUser:@"admin" password:@"123456" persistence:NSURLCredentialPersistenceForSession];
NSURLProtectionSpace *protectionSpace = [[NSURLProtectionSpace alloc]
initWithHost:@"xyz.com"
port:80
protocol:@"http"
realm:nil
authenticationMethod:NSURLAuthenticationMethodDefault];
[[NSURLCredentialStorage sharedCredentialStorage] setCredential:credential
forProtectionSpace:protectionSpace];
url = [NSURL URLWithString:urlString];
NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:url];
[request setHTTPMethod:@"GET"];
[request setValue:@"application/xml" forHTTPHeaderField:@"Content-Type"];
connection = [[NSURLConnection alloc] initWithRequest:request delegate:self];
NSURLResponse *response;
NSError *error;
NSData *returnData = [NSURLConnection sendSynchronousRequest:request returningResponse: &response error: &error];
NSString *dataStr=[[NSString alloc]initWithData:returnData encoding:NSUTF8StringEncoding];
NSLog(@"data == %@\n error in connecting == %@",dataStr,error);
我收到了以下回复
