我想使用AFNetworking进行批处理操作.我想下载3个json文件.
如何使用AFHTTPRequestOperation添加基本身份验证？
NSMutableArray *mutableOperations = [NSMutableArray array];
for (NSString *fileURL in filesToDownload) {
NSURLRequest *request = [NSURLRequest
requestWithURL:[NSURL URLWithString:fileURL]];
AFHTTPRequestOperation *operation = [[AFHTTPRequestOperation alloc]
initWithRequest:request];
[operation setCompletionBlockWithSuccess:^(AFHTTPRequestOperation *operation,id responSEObject) {
NSLog(@"success: %@",operation.responseString);
}
failure:^(AFHTTPRequestOperation *operation,NSError *error) {
NSLog(@"error: %@",operation.responseString);
}];
[mutableOperations addObject:operation];
}
NSArray *operations = [AFURLConnectionOperation batchOfRequestOperations:mutableOperations
progressBlock:^(NSUInteger numberOfFinishedOperations,NSUInteger totalNumberOfOperations) {
NSLog(@"%d of %d complete",numberOfFinishedOperations,totalNumberOfOperations);
} completionBlock:^(NSArray *operations) {
NSLog(@"All operations in batch complete");
}];
[[NSOperationQueue mainQueue] addOperations:operations waitUntilFinished:NO];
非常感谢你
解决方法
使用AuthenticationChallengeBlock来处理基本的身份验证挑战.
[operation setAuthenticationChallengeBlock:
^(NSURLConnection *connection,NSURLAuthenticationChallenge *challenge) {
NSURLCredential *cred = [NSURLCredential
credentialWithUser:@"username"
password:@"password"
persistence:NSURLCredentialPersistenceForSession];
[[challenge sender] useCredential:cred forAuthenticationChallenge:challenge];
}];
编辑：
另一个选择是通过请求头中的身份验证.
NSURLMutableRequest *request = [NSURLMutableRequest
requestWithURL:[NSURL URLWithString:fileURL]];
NSData* authData = [[[NSString
stringWithFormat:@"username:password"]
stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding]
dataUsingEncoding: NSASCIIStringEncoding];
NSString *finalAuth = [authData base64EncodedString];
finalAuth = [NSString stringWithFormat:@"Basic %@",finalAuth];
[request setValue:finalAuth forHTTPHeaderField:@"Authorization"];
另一个解决方案：
NSURLCredential *credential = [NSURLCredential
credentialWithUser:@"login"
password:@"password"
persistence:NSURLCredentialPersistenceForSession];
[operation setCredential:credential];
