post请求体封装如下：

- (void)postWithUrl:(NSString *)url body:(NSData *)body  success:(void(^)(NSDictionary *response))success failure:(void(^)(NSError *error))failur

{

NSString *requestUrl = @“”;

AFURLSessionManager *manager = [[AFURLSessionManager alloc] initWithSessionConfiguration:[NSURLSessionConfiguration defaultSessionConfiguration]];

//如果你不需要将通过body传 那就参数放入parameters里面

NSMutableURLRequest *request = [[AFHTTPRequestSerializer serializer] requestWithMethod:@"POST" URLString:requestUrl parameters:nil error:nil];

NSLog(@"requestURL:%@",requestUrl);

request.timeoutInterval= 10;

[request setValue:@"application/json" forHTTPHeaderField:@"Content-Type"];

// 设置body 在这里将参数放入到body

[request setHTTPBody:body];

AFHTTPResponseSerializer *responseSerializer = [AFHTTPResponseSerializer serializer];

responseSerializer.acceptableContentTypes = [NSSet setWithObjects:@"application/json",

@"text/html",

@"text/json",

@"text/javascript",

@"text/plain",

nil];

manager.responseSerializer = responseSerializer;

[[manager dataTaskWithRequest:request uploadProgress:nil downloadProgress:nil completionHandler:^(NSURLResponse *response,id responseObject,NSError *error){

if(responseObject!=nil){

success(responseObject);

}

if (error) {

failure(error);

}

}]resume];

}

调用：

NSDictionary *dict = @{@"name":@"hello",@"sex":@"男"};

NSData *data =    [NSJSONSerialization dataWithJSONObject:dict options:NSUTF8StringEncoding error:nil];

[self postWithUrl:@"" body:data showLoading:0 success:^(NSDictionary *response) {

//NSString *result = [[NSString alloc] initWithData:response  encoding:NSUTF8StringEncoding];

NSDictionary *resultDic = [NSJSONSerialization JSONObjectWithData:response options:NSJSONReadingMutableLeaves error:nil];  //解析

NSLog(@"%@",result);

} failure:^(NSError *error) {

}];

 

IOS AFN 通过body传递参数给服务器

2017-07-10 20:19 行走在砂砾中 

1. 此段代码适用于请求接口时传参为json格式，而非常见的dictionary。同时设置请求头的Content-Type: application/json;charset=UTF-8
2. 先将AFN文件导入 或者pod 。

AFNetwoking的默认Content-Type是application/x-www-form-urlencodem。若服务器要求Content-Type为applicaiton/json，为了和服务器对应，就必须修改AFNetworking的Content-Type

===========刚在其他博主里看到更省事的代码，下面的这段代码不推荐。可以直接略过用第二段代码块===

1.  
   NSDictionary *parameters= @{@"client_type":@"你的参数",@"你的参数":@"1"};
2.  
    
3.  
   //设置参数 根据你们服务器的格式设置。我们的后台需要传的是json格式的
4.  
    
5.  
   NSData *jsonData = [NSJSONSerialization dataWithJSONObject:parameters 
6.  
   options:NSJSONWritingPrettyPrinte  error:nil];
7.  
    
8.  
    //afn请求
9.  
    AFURLSessionManager *manager = [[AFURLSessionManager alloc] initWithSessionConfiguration:
10.  
    [NSURLSessionConfiguration defaultSessionConfiguration]];
11.  
     
12.  
          NSString * requestUrl  = @"你的请求地址";
13.  
        //如果你不需要在请求体里传参 那就参数放入parameters里面
14.  
          NSMutableURLRequest *request = [[AFHTTPRequestSerializer serializer]
15.  
    requestWithMethod:@"POST" URLString:requestUrl parameters:nil error:nil];
16.  
     
17.  
    // NSLog(@"requestURL:%@",requestUrl);
18.  
    request.timeoutInterval= 10;
19.  
     
20.  
    //这句话很重要，设置"Content-Type"类型 json类型跟后台大哥的一致
21.  
    [request setValue:@"application/json" forHTTPHeaderField:@"Content-Type"];
22.  
        // 设置参数放入到body请求体里。后台大哥让参数放在请求体里，因为没写这句代码，我TM调试浪费了半天
23.  
        [request setHTTPBody:jsonData];
24.  
     
25.  
        AFHTTPResponseSerializer *responseSerializer = [AFHTTPResponseSerializer serializer];
26.  
        responseSerializer.acceptableContentTypes = [NSSet setWithObjects:@"application/json",
27.  
    @"text/html","text/json", @"text/javascript",@"text/plain",  nil];
28.  
     
29.  
            manager.responseSerializer = responseSerializer;
30.  
     
31.  
        [[manager dataTaskWithRequest:request uploadProgress:nil downloadProgress:nil
32.  
    completionHandler:^(NSURLResponse *response,id responseObject,NSError *error){
33.  
     
34.  
               if(responseObject!=nil){
35.  
     
36.  
                   NSString *result = [[NSString alloc] initWithData:responseObject 
37.  
    encoding:NSUTF8StringEncoding];
38.  
      NSLog(@"%@",result);
39.  
     
40.  
               }
41.  
     
42.  
           }]resume];

    第二种解决方法：推荐

1.  
    
2.  
   NSDictionary *parameters= @{@"client_type":@"你的参数",@"你的参数":@"1"};
3.  
    
4.  
    
5.  
    
6.  
   AFHTTPSessionManager *session = [AFHTTPSessionManager manager];
7.  
   session.responseSerializer.acceptableContentTypes = [NSSet setWithObjects:@"application/json", @"text/html", @"text/plain", nil];
8.  
   //post 发送json格式数据的时候加上这两句。
9.  
   session.requestSerializer = [AFJSONRequestSerializer serializer];
10.  
    session.responseSerializer = [AFJSONResponseSerializer serializer];
11.  
    session.requestSerializer.timeoutInterval = 15;
12.  
    // NSString * requestUrl = @"http://47.244.143.48:8080/auth/getVerificationCode";
13.  
    NSString * requestUrl = @"http://192.168.1.10:8080/auth/getVerificationCode";
14.  
    [session POST:requestUrl parameters:parameters progress:^(NSProgress * _Nonnull uploadProgress) {
15.  
     
16.  
    } success:^(NSURLSessionDataTask * _Nonnull task, id _Nullable responseObject) {
17.  
    if (responseObject) {
18.  
    NSLog(@"post成功了%@",responseObject);
19.  
    }
20.  
     
21.  
    } failure:^(NSURLSessionDataTask * _Nullable task, NSError * _Nonnull error) {
22.  
    if (error) {
23.  
    NSLog(@"post失败了%@",error);
24.  
    }
25.  
    }];
