第八篇、封装NSURLSession网络请求框架
2024-08-21 18:15:58
主要功能介绍：
1.GET请求操作
2.POST请求操作
1.处理params参数（例如拼接成：usename="123"&password="123"）

#import "LYURLRequestSerialization.h" @interface LYURLRequestSerialization() @property (readwrite, nonatomic, strong) id value;

2.封装请求管理器
#import <Foundation/Foundation.h> @interface LYHTTPRequestOperationManager : NSObject -(void)driveTask:(nullable void(^)(NSData *__nullable data,NSURLResponse * __nullable response))success
failure:(nullable void (^)(NSError *__nullable error))failure; - (instancetype) initWithMethod:(NSString *)method URL:(NSString *)URL parameters:( id)parameters; @end
#import "LYHTTPRequestOperationManager.h"
#import "LYURLRequestSerialization.h" @interface LYHTTPRequestOperationManager() @property(nonatomic,strong) NSString *URL;
@property(nonatomic,strong) NSString *method;
@property(nonatomic,strong) NSDictionary *parameters;
@property(nonatomic,strong) NSMutableURLRequest *request;
@property(nonatomic,strong) NSURLSession *session;
@property(nonatomic,strong) NSURLSessionDataTask *task; @end @implementation LYHTTPRequestOperationManager - (instancetype)initWithMethod:(NSString *)method URL:(NSString *)URL parameters:(id)parameters
{
self = [super init];
if (!self) {
return nil;
}
self.URL = URL;
self.method = method;
self.parameters = parameters;
self.request = [NSMutableURLRequest requestWithURL:[NSURL URLWithString:URL]];
self.session = [NSURLSession sharedSession];
return self;
} -(void)test{
NSLog(@"URL = %@",self.URL);
} -(void)setRequest{
if ([self.method isEqual:@"GET"]&&self.parameters.count>) { self.request = [NSMutableURLRequest requestWithURL:[NSURL URLWithString:[[self.URL stringByAppendingString:@"?"] stringByAppendingString: [LYURLRequestSerialization LYQueryStringFromParameters:self.parameters]]]];
}
self.request.HTTPMethod = self.method; if (self.parameters.count>) {
[self.request addValue:@"application/x-www-form-urlencoded" forHTTPHeaderField:@"Content-Type"];
}
} -(void)setBody{
if (self.parameters.count>&&![self.method isEqual:@"GET"]) { self.request.HTTPBody = [[LYURLRequestSerialization LYQueryStringFromParameters:self.parameters] dataUsingEncoding:NSUTF8StringEncoding];
}
} -(void)setTaskWithSuccess:(void(^)(NSData *__nullable data,NSURLResponse * __nullable response))success
failure:(void (^)(NSError *__nullable error))failure
{
self.task = [self.session dataTaskWithRequest:self.request completionHandler:^(NSData * data,NSURLResponse *response,NSError *error){
if (error) {
failure(error);
}else{
if (success) {
success(data,response);
}
}
}];
[self.task resume];
} -(void)driveTask:(void(^)(NSData *__nullable data,NSURLResponse * __nullable response))success
failure:(void (^)(NSError *__nullable error))failure
{
[self setRequest];
[self setBody];
[self setTaskWithSuccess:success failure:failure];
}
@end
3.封装适配器
#import <Foundation/Foundation.h> @interface LyNetWork : NSObject +(void)requestWithMethod:(nullable NSString *)method
URL:(nullable NSString *)URL
success:(nullable void (^)(NSData *__nullable data,NSURLResponse * __nullable response))success
failure:(nullable void (^)(NSError *__nullable error))failure; +( void)requestGetWithURL:(nullable NSString *)URL
success:(nullable void (^)(NSData *__nullable data,NSURLResponse * __nullable response))success
failure:(nullable void (^)(NSError *__nullable error))failure; +(void)requestGetWithURL:(nullable NSString *)URL
parameters:(nullable id) parameters
success:(nullable void (^)(NSData *__nullable data,NSURLResponse * __nullable response))success
failure:(nullable void (^)(NSError *__nullable error))failure; +(void)requestPostWithURL:(nullable NSString *)URL
success:(nullable void (^)(NSData *__nullable data,NSURLResponse * __nullable response))success
failure:(nullable void (^)(NSError *__nullable error))failure; +(void)requestPostWithURL:(nullable NSString *)URL
parameters:(nullable id) parameters
success:(nullable void (^)(NSData *__nullable data,NSURLResponse * __nullable response))success
failure:(nullable void (^)(NSError *__nullable error))failure; @end
#import "LyNetWork.h"
#import "LYURLRequestSerialization.h"
#import "LYHTTPRequestOperationManager.h" @interface LyNetWork() @end @implementation LyNetWork //+(void)requestMethod:(NSString *)method
// URL:(NSString *)URL
// parameters:(id) parameters
// success:(void (^)(NSData *__nullable data,NSURLResponse * __nullable response))success
// failure:(void (^)(NSError *__nullable error))failure
//{
//
// LYHTTPRequestOperationManager *manange = [[LYHTTPRequestOperationManager alloc] initWithMethod:method URL:URL parameters:parameters];
// [manange driveTask:success failure:failure];
//} //不带parameters
+(void)requestWithMethod:(NSString *)method
URL:(NSString *)URL
success:(void (^)(NSData *__nullable data,NSURLResponse * __nullable response))success
failure:(void (^)(NSError *__nullable error))failure
{ LYHTTPRequestOperationManager *manange = [[LYHTTPRequestOperationManager alloc] initWithMethod:method URL:URL parameters:nil];
[manange driveTask:success failure:failure];
} //GET不带parameters
+(void)requestGetWithURL:(NSString *)URL
success:(void (^)(NSData *__nullable data,NSURLResponse * __nullable response))success
failure:(void (^)(NSError *__nullable error))failure
{ LYHTTPRequestOperationManager *manange = [[LYHTTPRequestOperationManager alloc] initWithMethod:@"GET" URL:URL parameters:nil];
[manange driveTask:success failure:failure];
}
//GET带parameters
+(void)requestGetWithURL:(NSString *)URL
parameters:(id) parameters
success:(void (^)(NSData *__nullable data,NSURLResponse * __nullable response))success
failure:(void (^)(NSError *__nullable error))failure
{ LYHTTPRequestOperationManager *manange = [[LYHTTPRequestOperationManager alloc] initWithMethod:@"GET" URL:URL parameters:parameters];
[manange driveTask:success failure:failure];
} //POST不带parameters
+(void)requestPostWithURL:(NSString *)URL
success:(void (^)(NSData *__nullable data,NSURLResponse * __nullable response))success
failure:(void (^)(NSError *__nullable error))failure
{ LYHTTPRequestOperationManager *manange = [[LYHTTPRequestOperationManager alloc] initWithMethod:@"POST" URL:URL parameters:nil];
[manange driveTask:success failure:failure];
}
//POST带parameters
+(void)requestPostWithURL:(NSString *)URL
parameters:(id) parameters
success:(void (^)(NSData *__nullable data,NSURLResponse * __nullable response))success
failure:(void (^)(NSError *__nullable error))failure
{ LYHTTPRequestOperationManager *manange = [[LYHTTPRequestOperationManager alloc] initWithMethod:@"POST" URL:URL parameters:parameters];
[manange driveTask:success failure:failure];
} @end
4.使用示例
NSString *postURL = @"http://cityuit.sinaapp.com/p.php";
NSString *getURL= @"http://cityuit.sinaapp.com/1.php"; id parmentersPost = @{
@"username":@"",
@"password":@""
};
id parmentersGet = @{
@"value":@"Lastday",
}; [LyNetWork requestWithMethod:@"POST"
URL:@"http://cityuit.sinaapp.com/1.php?value=Lastday"
success:^(NSData *data,NSURLResponse *response){
NSString *string = [[NSString alloc] initWithData:data encoding:NSUTF8StringEncoding];
NSLog(@"requestWithMethod = %@",string);
}
failure:^(NSError *error){
NSLog(@"====%@",error);
}]; [LyNetWork requestPostWithURL:postURL
parameters:parmentersPost
success:^(NSData *data,NSURLResponse *response){
NSString *string = [[NSString alloc] initWithData:data encoding:NSUTF8StringEncoding];
NSLog(@"requestPostWithURL(带参数) = %@",string);
}
failure:^(NSError *error){ }];
[LyNetWork requestPostWithURL:postURL
success:^(NSData *data,NSURLResponse *response){
NSString *string = [[NSString alloc] initWithData:data encoding:NSUTF8StringEncoding];
NSLog(@"requestPostWithURL(不带参数) = %@",string);
}
failure:^(NSError *error){ }]; [LyNetWork requestGetWithURL:getURL
parameters:parmentersGet
success:^(NSData *data,NSURLResponse *response){
NSString *string = [[NSString alloc] initWithData:data encoding:NSUTF8StringEncoding];
NSLog(@"requestGetWithURL(带参数) = %@",string);
}
failure:^(NSError *error){ }]; [LyNetWork requestGetWithURL:getURL
success:^(NSData *data,NSURLResponse *response){
NSString *string = [[NSString alloc] initWithData:data encoding:NSUTF8StringEncoding];
NSLog(@"requestGetWithURL(不带参数) = %@",string);
}
failure:^(NSError *error){ }];
