AFNetworking 是一个能够快速使用的ios和mac os x下的网络框架,它是构建在Foundation URL Loading System之上的,封装了网络的抽象层,可以方便的使用,AFNetworking是一个模块化架构,拥有丰富api的框架。
一、HTTP请求与操作:
1、AFHTTPRequestOperationManager:
该类封装与Web应用程序进行通信通过HTTP,包括要求制作,响应序列化,网络可达性监控和安全性,以及要求经营管理的常见模式。
GET 请求:
[objc] view
plaincopyprint?

![](https://oscdn.geek-share.com/Uploads/Images/Content/201611/9e12f1d3e499fc949c886e7c9e0484f9)
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);
}];
POST 带有表单参数的POST请求:
[objc] view

![](https://oscdn.geek-share.com/Uploads/Images/Content/201611/9e12f1d3e499fc949c886e7c9e0484f9)
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);
}];
POST Multi-Part格式的表单文件上传请求:
[objc] view

![](https://oscdn.geek-share.com/Uploads/Images/Content/201611/9e12f1d3e499fc949c886e7c9e0484f9)
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<AFMultipartFormData> formData) {
[formData appendPartWithFileURL:filePath name:@"image" error:nil];
} success:^(AFHTTPRequestOperation *operation, id responseObject) {
NSLog(@"Success: %@", responseObject);
} failure:^(AFHTTPRequestOperation *operation, NSError *error) {
NSLog(@"Error: %@", error);
}];
二、Session管理:
1、AFURLSessionManager:创建和管理制定的NSURLSession对象
2、NSURLSessionConfiguration对象必须实现<NSURLSessionTaskDelegate>, <NSURLSessionDataDelegate>, <NSURLSessionDownloadDelegate>, <NSURLSessionDelegate>协议
创建一个下载任务:
[objc] view
plaincopyprint?
![](https://oscdn.geek-share.com/Uploads/Images/Content/201611/a7c8e286f463007e2a900848b93dd72c.png)
![](https://oscdn.geek-share.com/Uploads/Images/Content/201611/9e12f1d3e499fc949c886e7c9e0484f9)
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];
创建一个数据流任务:
[objc] view
plaincopyprint?
![](https://oscdn.geek-share.com/Uploads/Images/Content/201611/a7c8e286f463007e2a900848b93dd72c.png)
![](https://oscdn.geek-share.com/Uploads/Images/Content/201611/9e12f1d3e499fc949c886e7c9e0484f9)
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];
四、使用AFHTTPRequestOperation
1、AFHTTPRequestOperation是使用HTTP或HTTPS协议的AFURLConnectionOperation的子类。
它封装的获取后的HTTP状态和类型将决定请求的成功与否。
2、虽然AFHTTPRequestOperationManager通常是最好的去请求的方式,但是AFHTTPRequestOpersion也能够单独使用。
通过GET方式:
[objc] view
plaincopyprint?
![](https://oscdn.geek-share.com/Uploads/Images/Content/201611/a7c8e286f463007e2a900848b93dd72c.png)
![](https://oscdn.geek-share.com/Uploads/Images/Content/201611/9e12f1d3e499fc949c886e7c9e0484f9)
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];
连续操作多个:
[objc] view
plaincopyprint?
![](https://oscdn.geek-share.com/Uploads/Images/Content/201611/a7c8e286f463007e2a900848b93dd72c.png)
![](https://oscdn.geek-share.com/Uploads/Images/Content/201611/9e12f1d3e499fc949c886e7c9e0484f9)
NSMutableArray *mutableOperations = [NSMutableArray array];
for (NSURL *fileURL in filesToUpload) {
NSURLRequest *request = [[AFHTTPRequestSerializer serializer] multipartFormRequestWithMethod:@"POST" URLString:@"http://example.com/upload" parameters:nil constructingBodyWithBlock:^(id<AFMultipartFormData> 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];
