我想在批处理操作中使用 AFNetworking。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
最佳答案
使用 AuthenticationChallengeBlock
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:
另一种选择是在请求 header 中传递身份验证。
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"];
另一种解决方案:
NSURLCredential *credential = [NSURLCredential
credentialWithUser:@"login"
password:@"password"
persistence:NSURLCredentialPersistenceForSession];
[operation setCredential:credential];
关于ios - 使用 AFHTTPRequestOperation 进行 AFNetworking 2 身份验证,我们在Stack Overflow上找到一个类似的问题: https://stackoverflow.com/questions/19587453/
