我正在尝试将POST
一个对象发送到服务器,但它无效。这就是我在做的事情。仅供参考,我正在使用MagicalRecords进行CoreData
轻松处理。
DBComments *comment = [DBComments MR_createEntity];
comment.body = @"This is body";
comment.subject = @"This is subject";
comment.commentable_id = [NSNumber numberWithInt:291110];
comment.send_email = [NSNumber numberWithBool:YES];
[[RKObjectManager sharedManager] postObject:comment path:URL_COMMENTS
parameters:nil
success:^(RKObjectRequestOperation *operation, RKMappingResult *mappingResult) {
KLog(@"success");
} failure:^(RKObjectRequestOperation *operation, NSError *error) {
KLog(@"fail");
}];
但我得到以下回应:
E restkit.network:RKObjectRequestOperation.m:576 Object request failed: Underlying HTTP request operation failed with error: Error Domain=org.restkit.RestKit.ErrorDomain Code=-1011 "Expected status code in (200-299), got 400" UserInfo=0x11b688c0 {NSLocalizedRecoverySuggestion={"error":"body is missing, commentable_id is missing"}, AFNetworkingOperationFailingURLRequestErrorKey=<NSMutableURLRequest: 0xc632e50> { URL: http://10.28.79.98:3002/comments }, NSErrorFailingURLKey=http://10.28.79.98:3002/comments, NSLocalizedDescription=Expected status code in (200-299), got 400, AFNetworkingOperationFailingURLResponseErrorKey=<NSHTTPURLResponse: 0xc23cf70> { URL: http://10.28.79.98:3002/comments } { status code: 400, headers {
"Cache-Control" = "no-cache";
Connection = "Keep-Alive";
"Content-Length" = 54;
"Content-Type" = "application/json";
Date = "Fri, 28 Mar 2014 07:45:01 GMT";
Server = "WEBrick/1.3.1 (Ruby/1.9.3/2012-04-20)";
"X-Request-Id" = c8b765e61a8d44020be26e9b3267096e;
"X-Runtime" = "0.010554";
"X-Ua-Compatible" = "IE=Edge";
} }}
正如您在响应中看到的那样,值未被POST
{"error":"body is missing, commentable_id is missing"}
这是我的映射配置
[objectManager addRequestDescriptorsFromArray:@[
// Comments
[RKRequestDescriptor requestDescriptorWithMapping:[self commentsRequestMapping]
objectClass:[DBComments class]
rootKeyPath:@""
method:RKRequestMethodPOST],
]];
- (RKObjectMapping *)commentsRequestMapping {
RKObjectMapping *commentsRequestMapping = [RKObjectMapping requestMapping];
[commentsRequestMapping addAttributeMappingsFromDictionary:@{
@"body" : @"body",
@"commentable_id" : @"commentable_id",
@"commentable_type" : @"commentable_type",
@"created_at" : @"created_at",
@"id" : @"id",
@"lft" : @"lft",
@"parent_id" : @"parent_id",
@"rgt" : @"rgt",
@"subject" : @"subject",
@"title" : @"title",
@"updated_at" : @"updated_at",
@"user_id" : @"user_id",
@"send_email" : @"send_email",
}];
return commentsRequestMapping;
}
我从未成功使用postObject
。我错过了什么吗?请帮忙。

如果服务器需要一组扁平的内容,那么请求描述符应该有一个nil密钥路径,而不是一个空字符串。
您发送的内容与服务器所需的内容相匹配非常重要,您应该使用跟踪日志记录和Charles(或类似工具)的组合来验证代码实际生成的内容。
