新建一个类
在.h文件中，提供网络相关的常用方法
GET请求
+(void)get:(NSString *)url params:(NSDictionary *)params success:(void (^)(id JSON))success failure:(void (^)(NSError *error))failure;
POST请求
+(void)post:(NSString *)url params:(NSDictionary *)params success:(void (^)(id JSON))success failure:(void (^)(NSError *error))failure;
PUT请求
+(void)put:(NSString *)url params:(NSDictionary *)params success:(void (^)(id JSON))success failure:(void (^)(NSError *error))failure;
网络状态监测
+(void)getDeviceNetWorkStates;
//+(UIAlertController *)showNetWorkStatusTipMesg:(NSString *)title ;
处理参数得到请求URL
+(NSString *)getURLwithParams:(NSString *)url secret:(NSString *)secret params:(NSMutableDictionary *)params;
在.m文件中实现方法
- GET
+ (void)get:(NSString *)url params:(NSDictionary *)params success:(void (^)(id))success failure:(void (^)(NSError *))failure
{
AFSecurityPolicy *policy = [[AFSecurityPolicy alloc] init];
[policy setAllowInvalidCertificates:YES]; //如果是需要验证自建证书，需要设置为YES
policy.validatesDomainName = NO;//不验证证书的域名
// 1.获得请求管理者
AFHTTPSessionManager * mgr = [AFHTTPSessionManager manager];
mgr.responseSerializer.acceptableContentTypes = [NSSet setWithObjects:@"application/json", @"text/json", @"text/javascript",@"text/html",@"text/css",@"text/plain", nil];
mgr.requestSerializer.timeoutInterval = timeout;
// mgr.operationQueue.maxConcurrentOperationCount = MaxOperationCountQueue;
// 2.发送GET请求
[mgr setSecurityPolicy:policy];
mgr.requestSerializer = [AFHTTPRequestSerializer serializer];
mgr.responseSerializer = [AFHTTPResponseSerializer serializer];
//添加 请求头
[mgr.requestSerializer setValue:@"abcd" forHTTPHeaderField:@"name"];
[mgr GET:url parameters:params progress:nil success:^(NSURLSessionDataTask * _Nonnull task, id _Nullable responseObject)
{
NSData *data = responseObject;
id JSON = [NSJSONSerialization JSONObjectWithData:data options:NSJSONReadingMutableContainers error:nil];
if (success) {
success(JSON);
}
} failure:^(NSURLSessionDataTask * _Nullable task, NSError * _Nonnull error) {
if (failure) {
failure(error);
}
}];
}
- POST
+ (void)post:(NSString *)url params:(NSDictionary *)params success:(void (^)(id))success failure:(void (^)(NSError *))failure
{
AFSecurityPolicy *policy = [[AFSecurityPolicy alloc] init];
[policy setAllowInvalidCertificates:YES];
// 1.获得请求管理者
AFHTTPSessionManager *mgr = [AFHTTPSessionManager manager];
mgr.responseSerializer.acceptableContentTypes = [NSSet setWithObjects:@"application/json", @"text/json", @"text/javascript",@"text/html",@"text/css",@"text/plain", nil];
mgr.requestSerializer.timeoutInterval = timeout;
// mgr.operationQueue.maxConcurrentOperationCount = MaxOperationCountQueue;
[mgr setSecurityPolicy:policy];
mgr.requestSerializer = [AFHTTPRequestSerializer serializer];
mgr.responseSerializer = [AFHTTPResponseSerializer serializer];
//添加 请求头
[mgr.requestSerializer setValue:@"abcd" forHTTPHeaderField:@"name"];
// 2.发送POST请求
[mgr POST:url parameters:params progress:nil success:^(NSURLSessionDataTask * _Nonnull task, id _Nullable responseObject) {
NSData *data = responseObject;
id JSON = [NSJSONSerialization JSONObjectWithData:data options:NSJSONReadingMutableContainers error:nil];
if (success) {
success(JSON);
}
} failure:^(NSURLSessionDataTask * _Nullable task, NSError * _Nonnull error) {
if (failure) {
failure(error);
}
}];
}
- PUT
+(void)put:(NSString *)url params:(NSDictionary *)params success:(void (^)(id))success failure:(void (^)(NSError *))failure{
AFSecurityPolicy *policy = [[AFSecurityPolicy alloc] init];
[policy setAllowInvalidCertificates:YES];
// 1.获得请求管理者
AFHTTPSessionManager *mgr = [AFHTTPSessionManager manager];
mgr.responseSerializer.acceptableContentTypes = [NSSet setWithObjects:@"application/json", @"text/json", @"text/javascript",@"text/html",@"text/css",@"text/plain", nil];
mgr.requestSerializer.timeoutInterval = timeout;
// mgr.operationQueue.maxConcurrentOperationCount = MaxOperationCountQueue;
[mgr setSecurityPolicy:policy];
mgr.requestSerializer = [AFHTTPRequestSerializer serializer];
mgr.responseSerializer = [AFHTTPResponseSerializer serializer];
[mgr PUT:url parameters:params success:^(NSURLSessionDataTask * _Nonnull task, id _Nullable responseObject) {
if (success) {
success(responseObject);
}
}failure:^(NSURLSessionDataTask * _Nullable task, NSError * _Nonnull error) {
if (failure) {
failure(error);
}
}];
}
- 同步请求
+ (void)setAppleEnv{
BOOL __block reqProcessed = NO;
NSString *URLString = @"http://......."
NSURLSession *session = [NSURLSession sharedSession];
[[session dataTaskWithURL:[NSURL URLWithString:URLString]
completionHandler:^(NSData *data,
NSURLResponse *response,
NSError *error) {
//接收
PDMessage *message = [PDMessage mj_objectWithKeyValues:data];
if (message.code == 0) {
NSLog(@"----0 shenhe code=0");
}else if ( message.code == 1){
NSLog(@"----0 product code=1");
}
reqProcessed = true;
}] resume];
while (!reqProcessed) {
[NSThread sleepForTimeInterval:0];
}
}
- 参数排序，拼接，加密，获得URL
+(NSString *)getURLwithParams:(NSString *)url secret:(NSString *)secret params:(NSMutableDictionary *)params{
//排序
NSArray * sortedKeys = [[params allKeys] sortedArrayUsingSelector: @selector(caseInsensitiveCompare:)];
NSMutableString *sparam = [[NSMutableString alloc] init];
for (int i = 0; i < sortedKeys.count; i++) {
NSString *key = [sortedKeys objectAtIndex:i];
NSString *value = [params objectForKey:key];
if (i == 0) {
[sparam appendFormat:@"%@=%@",key,value];
}else{
[sparam appendFormat:@"&%@=%@",key,value];
}
}
if(secret != nil){
//--加密工具方法
PDEncryptionTools *enCoder = [[PDEncryptionTools alloc] init];
NSString *sign = [enCoder getEncryption:sparam secret:secret];
params[@"sign"] = sign;
//拼接
[sparam appendFormat:@"&sign=%@",sign];
}
//请求地址
NSString *requestURL = [NSString stringWithFormat:@"%@?%@",url,sparam];
return requestURL;
}
- 网络状态监测
使用通知发布状态信息
+(void)getDeviceNetWorkStates{
AFNetworkReachabilityManager *manager = [AFNetworkReachabilityManager sharedManager];
[manager startMonitoring];
[manager setReachabilityStatusChangeBlock:^(AFNetworkReachabilityStatus status) {
switch (status) {
case AFNetworkReachabilityStatusReachableViaWWAN:
[[NSNotificationCenter defaultCenter] postNotificationName:@"netWorkState" object:nil userInfo:@{@"state":[NSString stringWithFormat:@"%zd",1]}];
break;
case AFNetworkReachabilityStatusReachableViaWiFi:
[[NSNotificationCenter defaultCenter] postNotificationName:@"netWorkState" object:nil userInfo:@{@"state":[NSString stringWithFormat:@"%zd",1]}];
break;
case AFNetworkReachabilityStatusNotReachable:
[[NSNotificationCenter defaultCenter] postNotificationName:@"netWorkState" object:nil userInfo:@{@"state":[NSString stringWithFormat:@"%zd",0]}];
break;
case AFNetworkReachabilityStatusUnknown:
[[NSNotificationCenter defaultCenter] postNotificationName:@"netWorkState" object:nil userInfo:@{@"state":[NSString stringWithFormat:@"%zd",-1]}];
break;
default:
break;
}
}];
}
