http请求
ios10之后访问http请求需要在info.plist中加入字段

<key>NSAppTransportSecurity</key>
<dict>
<key>NSAllowsArbitraryLoads</key>
<true/>
</dict>

核心模块

AFHTTPSessionManager是继承于AFURLSessionManager的，我们一般做网络请求都是用这个类，但是它本身是没有做实事的，只是做了一些简单的封装，把请求逻辑分发给父类AFURLSessionManager或者其它类去做。
AFHTTPSessionManager
Get请求
+(void)getJokeBySort:(NSString *)sort
page:(int)page
pageSize:(int)size
time:(NSString *)time
key:(NSString *)key
success:(void (^)( NSDictionary *resultDic))success
failure:(void (^)( NSError *error))failure{
AFHTTPSessionManager *manager = [AFHTTPSessionManager manager];
/*
requestSerializer 上传的参数是什么格式的
AFHTTPRequestSerializer 普通的http的编码格式，二进制 sort=sort&page=page,默认
AFJSONRequestSerializerjson 编码格式 "{"sort":"sort","page":"page"}"
AFPropertyListRequestSerializerplist 编码格式
*/
manager.requestSerializer = [AFHTTPRequestSerializer serializer];
/*
请求超时设置
*/
manager.requestSerializer.timeoutInterval = 20.f;
/*
[AFHTTPResponseSerializer serializer]; 直接使用“服务器本来返回的数据”，不做任何解析
[AFJSONResponseSerializer serializer]; 解析服务器数据,返回的是JSON数据,默认的
[AFXMLParserResponseSerializer serializer]; 解析服务器数据,返回的XML数据
*/
manager.responseSerializer = [AFHTTPResponseSerializer serializer];
/*
如果想在header里加东西的话token/User-Agent/Content-Type
[manager.requestSerializer setValue:token forHTTPHeaderField:@"token"];
*/
NSDictionary *para = @{
@"sort":sort,
@"page":[NSNumber numberWithInt:page],
@"pageSize":[NSNumber numberWithInt:size],
@"time":time,
@"key":key
};
NSString *url =@"http://v.juhe.cn/joke/content/list.php";
[manager GET:url parameters:para progress:^(NSProgress * _Nonnull downloadProgress) {

Post请求(x-www-form-urlencoded)

默认的Content-Type为application/x-www-form-urlencoded,且body中没有参数

-(void)postLogin{
[DataManager loginUserName:@"lt\\jinguanyd6" passWord:@"111111" Success:^(NSDictionary * _Nonnull resultDic) {

post请求(form-data形式需要上传文件)
+ (void)postImageSuccess:(void(^)(void))success
failure:(void(^)(NSError *error))failure{

[formData appendPartWithFormData:[@"611" dataUsingEncoding:NSUTF8StringEncoding] name:@"feedbackId"];
/*
*该方法的参数
1\. appendPartWithFileData：要上传的照片[二进制流]
2\. name：对应网站上[upload.php中]处理文件的字段（比如upload）
3\. fileName：要保存在服务器上的文件名
4\. mimeType：上传的文件的类型
*/
[formData appendPartWithFileData:imageData name:@"file" fileName:@"file.jpg" mimeType:@"image/jpeg"];

NSLog(@"---------%@",responseObject);
} failure:^(NSURLSessionDataTask * _Nullable task, NSError * _Nonnull error) {

}
AFURLSessionManager
post请求body中有参数,可配置Content-type
/*
post,body中有参数

+(void)cheakNewVisionSuccess:(void (^)( NSDictionary *resultDic))success
failure:(void (^)( NSError *error))failure{

});
}
return;
}
//设置Content-type为text/html; charset=utf-8,对应postman-body-raw-text/html
[mutaRequest addValue: @"text/html; charset=utf-8" forHTTPHeaderField:@"Content-Type"];
//添加body
NSString*body=@"{\"os\":\"2\"}";
[mutaRequest setHTTPBody:[body dataUsingEncoding:NSUTF8StringEncoding]];
__block NSURLSessionDataTask *dataTask = nil;
dataTask = [manager dataTaskWithRequest:mutaRequest uploadProgress:^(NSProgress * _Nonnull uploadProgress) {

if (error) {
if (failure) {
failure(error);
}
} else {
if (success) {
success(responseObject);
}
}
}];
[dataTask resume];
}
Content-Type
Content-Type代表发送端（客户端|服务器）发送的实体数据的数据类型。
比如：Content-Type：text/html;
代表发送端发送的数据格式是html
-
常见的媒体格式类型如下：
text/html ： HTML格式
text/plain ：纯文本格式
text/xml ： XML格式
image/gif ：gif图片格式
image/jpeg ：jpg图片格式
image/png：png图片格式 -
以application开头的媒体格式类型：
application/xhtml+xml ：XHTML格式
application/xml ： XML数据格式
application/atom+xml ：Atom XML聚合格式
application/json ： JSON数据格式
application/pdf ：pdf格式
application/msword ： Word文档格式
application/octet-stream ： 二进制流数据（如常见的文件下载）
application/x-www-form-urlencoded ： <form encType=””>中默认的encType，form表单数据被编码为key/value格式发送到服务器（表单默认的提交数据的格式） -
以audio开头的常见媒体格式文件：
'audio/x-wav' : wav文件
'audio/x-ms-wma' : wma 文件
'audio/mp3' : mp3文件 -
以video开头的常见媒体格式文件：
'video/x-ms-wmv' : wmv文件
'video/mpeg4' : mp4文件
'video/avi' : avi文件 -
另外一种常见的媒体格式是上传文件之时使用的：
multipart/form-data ： 需要在表单中进行文件上传时，就需要使用该格式
Content-Type 被指定为 application/x-www-form-urlencoded；例如 JQuery 和 QWrap 的 Ajax，Content-Type 默认值都是「application/x-www-form-urlencoded;charset=utf-8」
