今天在项目中要封装一个请求头但是用如下方法总是失败：
求其原因不知道：
于是乎改用了属性对象后居然成功了。。：

-(void)GET:(NSString *)url params:(NSMutableDictionary *)params success:(void (^)(id))success failure:(void (^)(NSError *))failure{
NSLog(@"%@",_manager.requestSerializer.HTTPRequestHeaders);
[_manager GET:url parameters:nil progress:nil success:^(NSURLSessionDataTask * _Nonnull task, id _Nullable responseObject) {
success(responseObject);
} failure:^(NSURLSessionDataTask * _Nullable task, NSError * _Nonnull error) {
failure(error);
}];
}
-(void)setHttpRequestheader:(NSDictionary *)headerFieldValueDictionary{
_manager.requestSerializer.timeoutInterval=10.0f;
if (headerFieldValueDictionary != nil) {
for (id httpHeaderField in headerFieldValueDictionary.allKeys) {
id value = headerFieldValueDictionary[httpHeaderField];
if ([httpHeaderField isKindOfClass:[NSString class]] && [value isKindOfClass:[NSString class]]) {
[_manager.requestSerializer setValue:(NSString *)value forHTTPHeaderField:(NSString *)httpHeaderField];//这种情况设置就成功了。。
} else {
NSLog(@"Error, class of key/value in headerFieldValueDictionary should be NSString.");
}
}
}
}

AFNetworking的坑真不少。。
