typedef void(^RequestCompletionBlock) (id result, BOOL succeed);

#import <AFNetworking.h>

• GET 請求

+ (void)commonRequestByGetWithURL:(NSString *)url parameters:(NSDictionary *)parameters completion:(RequestCompletionBlock)completion
{
    AFHTTPSessionManager *manager = [AFHTTPSessionManager manager];
    manager.requestSerializer=[AFJSONRequestSerializer serializer];
    manager.responseSerializer = [AFJSONResponseSerializer serializer];
    manager.requestSerializer.timeoutInterval = 30;
    [manager GET:url parameters:parameters success:^(NSURLSessionDataTask *task, id responseObject) {
        completion(responseObject,YES);
    } failure:^(NSURLSessionDataTask *task, NSError *error) {
        completion(error,NO);
    }];
    
}

• POST請求

+ (void)commonRequestByPostWithURL:(NSString *)url parameters:(NSDictionary *)parameters completion:(RequestCompletionBlock)completion
{
    AFHTTPSessionManager *manager = [AFHTTPSessionManager manager];
    manager.requestSerializer=[AFJSONRequestSerializer serializer];
    manager.responseSerializer = [AFJSONResponseSerializer serializer];
    [manager.requestSerializer setValue:@"text/json;charset=utf-8" forHTTPHeaderField:@"Content-Type"];
    manager.requestSerializer.timeoutInterval = 30;
    [manager POST:url parameters:parameters success:^(NSURLSessionDataTask *task, id responseObject) {
        completion(responseObject,YES);
    } failure:^(NSURLSessionDataTask *task, NSError *error) {
        completion(error,NO);
    }];
}

-上傳圖片

+ (void)commonUploadWithUrl:(NSString *)url image:(NSData *)imageData imageName:(NSString *)imageName completion:(RequestCompletionBlock)completion
{
    AFHTTPRequestOperationManager *manager = [AFHTTPRequestOperationManager manager];
    [manager POST:url parameters:nil constructingBodyWithBlock:^(id<AFMultipartFormData> formData) {
        NSString *newName = [NSString stringWithFormat:@"%@%@",imageName,@".png"];
        // 上傳圖片
        [formData appendPartWithFileData:imageData name:@"portrait" fileName:newName mimeType:@""];
        
    } success:^(AFHTTPRequestOperation *operation, id responseObject) {
        completion(responseObject,YES);
    } failure:^(AFHTTPRequestOperation *operation, NSError *error) {
        completion(error,NO);
    }];
}

-下載

+ (void)commonDownloadWithUrl:(NSString *)url filePath:(NSURL *)filePath completion:(RequestCompletionBlock)completion
{
    NSURLSessionConfiguration *configuration = [NSURLSessionConfiguration defaultSessionConfiguration];
    AFURLSessionManager *manager = [[AFURLSessionManager alloc] initWithSessionConfiguration:configuration];
    
//    NSURL *URL = [NSURL URLWithString:@"http://example.com/download.zip"];
    NSURL *URL = [NSURL URLWithString:url];
    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);
        if (error) {
