我正在尝试使用 RestKit 将 POST 请求中的 JSON 数据发送到服务器，但出现错误
Expected content type {(
"application/x-www-form-urlencoded",
"application/json"
)}, got text/plain
我写的代码是：
NSURL *url=[NSURL URLWithString:[NSString stringWithFormat:@"%@%@",BASE_SERVICE_URL,TASK_SERVICE_URL]];
RKObjectMapping *mapping=[RKObjectMapping mappingForClass:[LoginData class]];
[mapping addAttributeMappingsFromDictionary:@{@"s":@"status",
@"message":@"message"}];
RKResponseDescriptor *descriptor=[RKResponseDescriptor responseDescriptorWithMapping:mapping method:RKRequestMethodPOST pathPattern:nil keyPath:@"" statusCodes:0];
NSMutableURLRequest *request=[[NSMutableURLRequest alloc]initWithURL:url];
[request setHTTPMethod:@"POST"];
[request addValue:@"application/json" forHTTPHeaderField:@"Content-Type"];
NSDictionary *dict=@{@"task":@"storeProfile",
@"fdate":@"01.01.2013",
@"tdate":@"19.08.2013",
@"keyword":@"taxi && cab",
@"AlertHours":@"120",
@"AlertDay":@"0",
@"AlertTimeStart":@"12:00",
@"AlertTimeEnd":@"18:00",
@"topic":@[
@{@"tname":@"Politics"},
@{@"tname":@"Economy"}
],
@"publication":@[
@{@"pname":@"Vijay Times Online"},
@{@"pname":@"Leisure Opportunities"}
]
};
NSError *error=nil;
NSData *jsonData=[NSJSONSerialization dataWithJSONObject:dict options:kNilOptions error:&error];
if (error) {
NSLog(@"%@",error.localizedDescription);
return;
}
[request setHTTPBody:jsonData];
operation=[[RKObjectRequestOperation alloc]initWithRequest:request responseDescriptors:@[descriptor]];
[operation setCompletionBlockWithSuccess:^(RKObjectRequestOperation *operation, RKMappingResult *mappingResult) {
LoginData *data=[mappingResult.dictionary objectForKey:@""];
NSLog(@"%@",data.message);
} failure:^(RKObjectRequestOperation *operation, NSError *error) {
NSLog(@"ERROR:%@",error.localizedDescription);
}];
[operation start];
有人可以帮我弄清楚到底是什么问题吗？我也尝试将内容类型设置如下：
[request addValue:@"application/application/x-www-form-urlencoded; charset=UTF-8" forHTTPHeaderField:@"Content-Type"];
