我刚刚开始使用RestKit 0.20.0,我在创建格式良好的
JSON请求时遇到了麻烦.
我得到这个(从休息工具包日志)：
request.body=title=A%20glorIoUs%20walk%20in%20the%20woods&startDateTime=2013-01-13%2016%3A09%3A33%20%2B0000&endDateTime=2013-01-13%2016%3A09%3A43%20%2B0000&points[][longitude]=-122.0307725&points[][latitude]=37.3310798&points[][longitude]=-122.0307334&points[][latitude]=37.33154242&points[][longitude]=-122.03075743&points[][latitude]=37.33138305&points[][longitude]=-122.03075659&points[][latitude]=37.33131185&points[][longitude]=-122.03057969&points[][latitude]=37.33156519&points[][longitude]=-122.03075535&points[][latitude]=37.33144466&points[][longitude]=-122.03076342&points[][latitude]=37.33123666&points[][longitude]=-122.03074488&points[][latitude]=37.33149482&points[][longitude]=-122.03068145&points[][latitude]=37.33155419&points[][longitude]=-122.03062909&points[][latitude]=37.33156564&points[][longitude]=-122.03076853&points[][latitude]=37.33115792
当我想要这个(带有大括号的普通json对象和points属性的数组)时：
{
title: "Something",startDateTime: "dateinfo",endDateTime: "moredateinfo",points: [
{
latitude: "37.33131313",longitude: "122.4325454"
},{
latitude: "37.33131313",longitude: "122.4325454"
}
]
}
我有两个主要对象：DLWalk包含一个DLPoint对象的NSSet(它们是CoreData对象,但目前我忽略了它,只关注创建HTTP请求)
这是我用来创建请求的代码：
// Point mapping
RKObjectMapping *mappingPoint = [RKObjectMapping requestMapping];
[mappingPoint addAttributeMappingsFromArray:@[@"latitude",@"longitude"]];
RKRequestDescriptor *reqDescPoint = [RKRequestDescriptor requestDescriptorWithMapping:mappingPoint objectClass:[DLPoint class] rootKeyPath:nil];
// Walk mapping
RKObjectMapping *mappingWalk = [RKObjectMapping requestMapping];
[mappingWalk addAttributeMappingsFromArray:@[@"endDateTime",@"startDateTime",@"title"]];
RKRequestDescriptor *reqDescWalk = [RKRequestDescriptor requestDescriptorWithMapping:mappingWalk objectClass:[DLWalk class] rootKeyPath:nil];
// Define the relationship mapping
[mappingWalk addPropertyMapping:[RKRelationshipMapping relationshipMappingFromKeyPath:@"points" toKeyPath:@"points" withMapping:mappingPoint]];
RKObjectManager *manager = [RKObjectManager managerWithBaseURL:[NSURL URLWithString:@"http://192.168.1.10:8080"]];
[manager addRequestDescriptor:reqDescWalk];
[manager addRequestDescriptor:reqDescPoint];
[manager addResponseDescriptor:responseDescriptor];
// POST to create
[manager postObject:walk path:@"/walk/save" parameters:nil success:nil failure:nil];
所以问题是：为什么我的POST主体中没有看到正常的JSON对象？
解决方法
你得到的是request.body是URL编码的,这是RESTKit的默认行为,通常工作正常.
如果您希望它是JSON编码的,只需在发布查询之前插入此行
manager.requestSerializationMIMEType=RKMIMETypeJSON;
有关这方面的更多信息,请查看RKObjectManager类的API文档：
requestSerializationMIMEType
