我收到此错误，但不知道为什么：/

2015-02-19 10:53:45.005 Agendize[4233:60b] Error Domain=com.alamofire.error.serialization.response Code=-1011 "Request failed: not found (404)" UserInfo=0x1782e4980 com.alamofire.serialization.response.error.response=<NSHTTPURLResponse: 0x17022e3c0>  URL: https://mylink   status code: 404, headers 
Connection = "keep-alive";
"Content-Length" = 104;
Date = "Thu, 19 Feb 2015 16:12:32 GMT";
Server = "nginx/1.1.19";

这是我的 xcode 请求：

NSError *error;
NSData *jsonData = [NSJSONSerialization dataWithJSONObject:parametersDictionary options:NSJSONWritingPrettyPrinted error:&error];

NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:url
                                                       cachePolicy:NSURLRequestReloadIgnoringCacheData  timeoutInterval:10];

[request setHTTPMethod:@"POST"];
[request setValue:@"Basic: someValue" forHTTPHeaderField:@"Authorization"];
[request setValue: @"application/json" forHTTPHeaderField:@"Content-Type"];
[request setHTTPBody:jsonData];

AFHTTPRequestOperation *operation = [[AFHTTPRequestOperation alloc] initWithRequest:request];

请帮忙！！！

【问题讨论】：

所以...你的错误是告诉你你的请求没有找到你正在寻找的任何东西。使用您提供的占位符数据，无法确定问题所在。使用 REST 客户端来测试您的端点和请求。查看Postman

【参考方案1】：

NSError *error=nil;
NSString *url = @"Your URL to post data";
NSData *jsonRequestDict= [NSJSONSerialization dataWithJSONObject:userDict options:NSJSONWritingPrettyPrinted error:&error];
NSString *jsonCommand=[[NSString alloc] initWithData:jsonRequestDict encoding:NSUTF8StringEncoding];
NSLog(@"***jsonCommand***%@",jsonCommand);

NSDictionary *params =[NSDictionary dictionaryWithObjectsAndKeys:jsonCommand,@"requestParam", nil];
AFHTTPRequestOperationManager *manager = [AFHTTPRequestOperationManager manager];
manager.requestSerializer = [AFHTTPRequestSerializer serializer];
manager.responseSerializer = [AFHTTPResponseSerializer serializer];  //AFHTTPResponseSerializer serializer
manager.responseSerializer.acceptableContentTypes = [manager.responseSerializer.acceptableContentTypes setByAddingObject:@"text/html"];

[manager POST:url parameters:params constructingBodyWithBlock:^(id<AFMultipartFormData> formData) 

 success:^(AFHTTPRequestOperation *operation, id responseObject) 
    NSError *error=nil;
    NSString *responseStr = [[NSString alloc] initWithData:responseObject encoding:NSUTF8StringEncoding];
    NSLog(@"Request Successful, response '%@'", responseStr);
    NSMutableDictionary *jsonResponseDict= [NSJSONSerialization JSONObjectWithData:responseObject options:kNilOptions error:&error];
    NSLog(@"Response Dictionary:: %@",jsonResponseDict);

 failure:^(AFHTTPRequestOperation *operation, NSError *error) 
    NSLog(@"Error: %@", error);
];
