我已经浏览了关于此主题的多篇文章，但无法解决问题。 - 我在邮递员以下结果：客观c - 试图将“原始”“application/json”数据发布到服务器API

请求通过邮递员发送与以下原料 - 应用程序/ JSON体：收到

成功响应：

然而，当我尝试使用以下代码获得相同的工作时

NSDictionary *postContent = @{ @"interests" : @"[\"TECHNOLOGY\",\"COOKING\",\"FINANCE\",\"SPORTS\",\"PHOTOGRAPHY\",\"FASHION\"]", @"user" : @"0", @"deviceId" : @"abcd", @"country_code" : @"IN" }; 

NSError *error = nil; 
NSData *postdata = [NSJSONSerialization dataWithJSONObject:postContent options:0 error:&error]; 

NSString *postLength = [NSString stringWithFormat:@"%lu", (unsigned long)[postdata length]]; 

NSMutableURLRequest *request = [[NSMutableURLRequest alloc] init]; 
[request setURL:[NSURL URLWithString:HOME_VIEWS]]; 
[request setValue:@"application/json" forHTTPHeaderField:@"Content-Type"]; 
[request setHTTPMethod:@"POST"]; 
[request setValue:postLength forHTTPHeaderField:@"Content-Length"]; 
[request setHTTPBody:postdata]; 

NSURLSession *session = [NSURLSession sessionWithConfiguration:[NSURLSessionConfiguration defaultSessionConfiguration]]; 
[[session dataTaskWithRequest:request completionHandler:^(NSData *data, NSURLResponse *response, NSError *error) { 
    NSString *requestReply = [[NSString alloc] initWithData:data encoding:NSASCIIStringEncoding]; 
    NSLog(@"requestReply: %@", requestReply); 
}] resume];

我总是零字节的数据得到以下错误：

 { status code: 404, headers { 
    Connection = close; 
    "Content-Type" = "application/json; charset=utf-8"; 
    Date = "Thu, 15 Dec 2016 11:51:29 GMT"; 
    "Set-Cookie" = "JSESSIONID=B0FE830D979F7BFAD0DDA67AEB9E2999.views; Path=/proliphiq"; 
    "Transfer-Encoding" = Identity; 
    "X-Powered-By" = "Servlet 2.5; JBoss-5.0/JBossWeb-2.1"; 
} }

404通常意味着未找到URL。你确定'[NSURL URLWithString：HOME_VIEWS]'指向一个有效的网址吗？三重检查一个。 – Ramon

嗨拉蒙 - 是的，这是正确的。我打印了URL并在浏览器中使用，并且工作正常。 POSTman也使用相同的URL –

进口 “AFNetworking.h”

NSString *url = [NSString stringWithFormat:Url]; 
//NSDictionary *parameters = @{@"age": @(_age.intValue)}; 
NSDictionary *parameters = @{@"age": @(66)}; 

AFHTTPSessionManager *manager = [AFHTTPSessionManager manager]; 
manager.responseSerializer = [AFJSONResponseSerializer serializerWithReadingOptions:NSJSONReadingAllowFragments]; 
manager.requestSerializer = [AFJSONRequestSerializer serializer]; 
[manager.requestSerializer setValue:@"application/json" forHTTPHeaderField:@"Content-Type"]; 
[manager POST:url parameters:parameters progress:nil success:^(NSURLSessionDataTask *task, id responseObject){ 


    NSLog(@"JSON--Age: %@", responseObject); 
    NSDictionary *value = [responseObject objectForKey:@"data"]; 
    NSLog(@"JSON--Age-Stock: %@", [value objectForKey:@"stock"]); 

} failure:^(NSURLSessionDataTask *task, NSError *error) { 
    NSLog(@"Error--: %@", error); 
}];
