现在大家都喜欢用AFNetworking进行ios应用程序开发,因为有人维护。看来一下官方文档,把使用的代码简单罗列一下:
- Podfile
- platform :ios, '7.0'
- pod "AFNetworking", "~> 2.0"
方法一:GET 请求
- AFHTTPRequestOperationManager *manager = [AFHTTPRequestOperationManager manager];
- [manager GET:@"http://example.com/resources.json" parameters:nil success:^(AFHTTPRequestOperation *operation, id responseObject) {
- NSLog(@"JSON: %@", responseObject);
- } failure:^(AFHTTPRequestOperation *operation, NSError *error) {
- NSLog(@"Error: %@", error);
- }];
方法二:POST 请求
- AFHTTPRequestOperationManager *manager = [AFHTTPRequestOperationManager manager];
- NSDictionary *parameters = @{@"foo": @"bar"};
- [manager POST:@"http://example.com/resources.json" parameters:parameters success:^(AFHTTPRequestOperation *operation, id responseObject) {
- NSLog(@"JSON: %@", responseObject);
- } failure:^(AFHTTPRequestOperation *operation, NSError *error) {
- NSLog(@"Error: %@", error);
- }];
方法三:POST Multi-Part Request
- AFHTTPRequestOperationManager *manager = [AFHTTPRequestOperationManager manager];
- NSDictionary *parameters = @{@"foo": @"bar"};
- NSURL *filePath = [NSURL fileURLWithPath:@"file://path/to/image.png"];
- [manager POST:@"http://example.com/resources.json" parameters:parameters constructingBodyWithBlock:^(id formData) {
- [formData appendPartWithFileURL:filePath name:@"image" error:nil];
- } success:^(AFHTTPRequestOperation *operation, id responseObject) {
- NSLog(@"Success: %@", responseObject);
- } failure:^(AFHTTPRequestOperation *operation, NSError *error) {
- NSLog(@"Error: %@", error);
- }];
方法四:创建一个下载文件任务
- NSURLSessionConfiguration *configuration = [NSURLSessionConfiguration defaultSessionConfiguration];
- AFURLSessionManager *manager = [[AFURLSessionManager alloc] initWithSessionConfiguration:configuration];
- NSURL *URL = [NSURL URLWithString:@"http://example.com/download.zip"];
- NSURLRequest *request = [NSURLRequest requestWithURL:URL];
- NSURLSessionDownloadTask *downloadTask = [manager downloadTaskWithRequest:request progress:nil destination:^NSURL *(NSURL *targetPath, NSURLResponse *response) {
- NSURL *documentsDirectoryURL = [[NSFileManager defaultManager] URLForDirectory:NSDocumentDirectory inDomain:NSUserDomainMask appropriateForURL:nil create:NO error:nil];
- return [documentsDirectoryURL URLByAppendingPathComponent:[response suggestedFilename]];
- } completionHandler:^(NSURLResponse *response, NSURL *filePath, NSError *error) {
- NSLog(@"File downloaded to: %@", filePath);
- }];
- [downloadTask resume];
方法五:创建一个上传文件任务
- NSURLSessionConfiguration *configuration = [NSURLSessionConfiguration defaultSessionConfiguration];
- AFURLSessionManager *manager = [[AFURLSessionManager alloc] initWithSessionConfiguration:configuration];
- NSURL *URL = [NSURL URLWithString:@"http://example.com/upload"];
- NSURLRequest *request = [NSURLRequest requestWithURL:URL];
- NSURL *filePath = [NSURL fileURLWithPath:@"file://path/to/image.png"];
- NSURLSessionUploadTask *uploadTask = [manager uploadTaskWithRequest:request fromFile:filePath progress:nil completionHandler:^(NSURLResponse *response, id responseObject, NSError *error) {
- if (error) {
- NSLog(@"Error: %@", error);
- } else {
- NSLog(@"Success: %@ %@", response, responseObject);
- }
- }];
- [uploadTask resume];
方法六:创建一个上传文件任务并显示进度
- NSMutableURLRequest *request = [[AFHTTPRequestSerializer serializer] multipartFormRequestWithMethod:@"POST" URLString:@"http://example.com/upload" parameters:nil constructingBodyWithBlock:^(id formData) {
- [formData appendPartWithFileURL:[NSURL fileURLWithPath:@"file://path/to/image.jpg"] name:@"file" fileName:@"filename.jpg" mimeType:@"image/jpeg" error:nil];
- } error:nil];
- AFURLSessionManager *manager = [[AFURLSessionManager alloc] initWithSessionConfiguration:[NSURLSessionConfiguration defaultSessionConfiguration]];
- NSProgress *progress = nil;
- NSURLSessionUploadTask *uploadTask = [manager uploadTaskWithStreamedRequest:request progress:&progress completionHandler:^(NSURLResponse *response, id responseObject, NSError *error) {
- if (error) {
- NSLog(@"Error: %@", error);
- } else {
- NSLog(@"%@ %@", response, responseObject);
- }
- }];
- [uploadTask resume];
方法七:创建一个上传数据data任务
- NSURLSessionConfiguration *configuration = [NSURLSessionConfiguration defaultSessionConfiguration];
- AFURLSessionManager *manager = [[AFURLSessionManager alloc] initWithSessionConfiguration:configuration];
- NSURL *URL = [NSURL URLWithString:@"http://example.com/upload"];
- NSURLRequest *request = [NSURLRequest requestWithURL:URL];
- NSURLSessionDataTask *dataTask = [manager dataTaskWithRequest:request completionHandler:^(NSURLResponse *response, id responseObject, NSError *error) {
- if (error) {
- NSLog(@"Error: %@", error);
- } else {
- NSLog(@"%@ %@", response, responseObject);
- }
- }];
- [dataTask resume];
方法八:获取网络状态
- [[AFNetworkReachabilityManager sharedManager] setReachabilityStatusChangeBlock:^(AFNetworkReachabilityStatus status) {
- NSLog(@"Reachability: %@", AFStringFromNetworkReachabilityStatus(status));
- }];
方法九: HTTP Manager Reachability
- NSURL *baseURL = [NSURL URLWithString:@"http://example.com/"];
- AFHTTPRequestOperationManager *manager = [[AFHTTPRequestOperationManager alloc] initWithBaseURL:baseURL];
- NSOperationQueue *operationQueue = manager.operationQueue;
- [manager.reachabilityManager setReachabilityStatusChangeBlock:^(AFNetworkReachabilityStatus status) {
- switch (status) {
- case AFNetworkReachabilityStatusReachableViaWWAN:
- case AFNetworkReachabilityStatusReachableViaWiFi:
- [operationQueue setSuspended:NO];
- break;
- case AFNetworkReachabilityStatusNotReachable:
- default:
- [operationQueue setSuspended:YES];
- break;
- }
- }];
- [manager.reachabilityManager startMonitoring];
方法十:AFHTTPRequestOperation的GET请求
- NSURL *URL = [NSURL URLWithString:@"http://example.com/resources/123.json"];
- NSURLRequest *request = [NSURLRequest requestWithURL:URL];
- AFHTTPRequestOperation *op = [[AFHTTPRequestOperation alloc] initWithRequest:request];
- op.responseSerializer = [AFJSONResponseSerializer serializer];
- [op setCompletionBlockWithSuccess:^(AFHTTPRequestOperation *operation, id responseObject) {
- NSLog(@"JSON: %@", responseObject);
- } failure:^(AFHTTPRequestOperation *operation, NSError *error) {
- NSLog(@"Error: %@", error);
- }];
- [[NSOperationQueue mainQueue] addOperation:op];
方法十一:Batch of Operations
- NSMutableArray *mutableOperations = [NSMutableArray array];
- for (NSURL *fileURL in filesToUpload) {
- NSURLRequest *request = [[AFHTTPRequestSerializer serializer] multipartFormRequestWithMethod:@"POST" URLString:@"http://example.com/upload" parameters:nil constructingBodyWithBlock:^(id formData) {
- [formData appendPartWithFileURL:fileURL name:@"images[]" error:nil];
- }];
- AFHTTPRequestOperation *operation = [[AFHTTPRequestOperation alloc] initWithRequest:request];
- [mutableOperations addObject:operation];
- }
- NSArray *operations = [AFURLConnectionOperation batchOfRequestOperations:@[...] progressBlock:^(NSUInteger numberOfFinishedOperations, NSUInteger totalNumberOfOperations) {
- NSLog(@"%lu of %lu complete", numberOfFinishedOperations, totalNumberOfOperations);
- } completionBlock:^(NSArray *operations) {
- NSLog(@"All operations in batch complete");
- }];
- [[NSOperationQueue mainQueue] addOperations:operations waitUntilFinished:NO];
方法十二:获取请求的一些信息(我也没有用过,不太常用)
- Request Serialization
- Request serializers create requests from URL strings, encoding parameters as either a query string o r HTTP body.
- NSString *URLString = @"http://example.com";
- NSDictionary *parameters = @{@"foo": @"bar", @"baz": @[@1, @2, @3]};
- Query String Parameter Encoding
- [[AFHTTPRequestSerializer serializer] requestWithMethod:@"GET" URLString:URLString parameters:parameters error:nil];
- GET http://example.com?foo=bar&baz[]=1&baz[]=2&baz[]=3
- URL Form Parameter Encoding
- [[AFHTTPRequestSerializer serializer] requestWithMethod:@"POST" URLString:URLString parameters:parameters];
- POST http://example.com/
- Content-Type: application/x-www-form-urlencoded
- foo=bar&baz[]=1&baz[]=2&baz[]=3
- JSON Parameter Encoding
- [[AFJSONRequestSerializer serializer] requestWithMethod:@"POST" URLString:URLString parameters:parameters];
- POST http://example.com/
- Content-Type: application/json
- {"foo": "bar", "baz": [1,2,3]}
