Ios 带休息套件的邮政

我有一个JSON结束路径，它接受以下格式的post请求

  {'values': [
    {
     "date":<measurement date as Unix time stamp>
     "value":<weight>
    }
    {
     "date":<measurement date as Unix time stamp>
     "value":<weight>
    }
     ...]}

数据结构的编辑

我的数据结构很简单（我想）：

---

我想发布一个包含条目的EntryCollection。EntryCollection的映射是“entries->values”，Entry的映射是“date->date，weight->value”。

在任何情况下，您的JSON请求负载必须确认为以下数据结构：

NSArray

   |
   |______NSDictionary ->Key: Date Value: weight
   |                   ->Key: value Value: weight
   |
   |______NSDictionary ->Key: Date Value: weight
   |                   ->Key: value Value: weight
   |
   |______NSDictionary ->Key: Date Value: weight
                       ->Key: value Value: weight

---

NSArray

和

NSDictionary

都与

JSON

数据格式完全兼容。我不知道您的底层对象结构，但最终这个数组应该作为请求负载

NSData

发布，您就可以完成了。

好吧，如果您在映射方面有问题，那么您必须显示您的模型、类和映射，或者将

RKLogConfigureByName（“RestKit/ObjectMapping”，RKLogLevelTrace）放入其中在代码中的某个地方，让我们看看输出

另一种选择是，如果您的实体结构与要发布到服务器的内容不同，则可以使用嵌入式
AFNetworking
client并执行简单的请求

 [[RKObjectManager sharedManager].HTTPClient postPath:@"" parameters:nil success:^(AFHTTPRequestOperation *operation, id responseObject) {
        NSLog(@"WHOOO");

    } failure:^(AFHTTPRequestOperation *operation, NSError *error) {
        //
    }];

我找到了解决办法。事实证明，我需要一个关系映射来描述JSON中隐含的层次结构。因为每个值实体都没有类型，所以我创建了一个“空”映射，并将关系映射添加到其中。
我还忘了设置正确的MIMEType和反转类的属性映射。我想需要在restkit中呆上几天才能掌握它

RKObjectMapping *entryMapping = [RKObjectMapping requestMapping];
        [entryMapping addAttributeMappingsFromDictionary:[SingleEntry attributesMapping]];
        RKObjectMapping *entrySerializedMapping = [entryMapping inverseMapping];

    RKRelationshipMapping *entryRelationship = [RKRelationshipMapping relationshipMappingFromKeyPath:@"entries" toKeyPath:@"values" withMapping:entrySerializedMapping];

    RKObjectMapping *valueMapping = [RKObjectMapping requestMapping];

    [valueMapping addPropertyMapping:valueMapping];

    RKRequestDescriptor *descriptor = [RKRequestDescriptor requestDescriptorWithMapping:valueMapping objectClass:[EntriesCollection class] rootKeyPath:nil];

    [self.objectManager addRequestDescriptor:descriptor];
    self.objectManager.requestSerializationMIMEType = RKMIMETypeJSON;

    NSString *path = [self pathForPOST];

    [self.objectManager postObject:entryCollection path:path parameters:nil success:nil failure:nil];

JSON可以有一个字典作为根，这对映射问题没有任何帮助……您的类结构确实不清楚，因为您的映射中有许多不同的类，并且大多数映射都是局部的。您可能会发现创建映射更容易，就好像您正在解析JSON，然后使用相反的方法。否则您需要显示完整的类结构。我已经用数据结构更新了我的问题。
 [[RKObjectManager sharedManager].HTTPClient postPath:@"" parameters:nil success:^(AFHTTPRequestOperation *operation, id responseObject) {
        NSLog(@"WHOOO");

    } failure:^(AFHTTPRequestOperation *operation, NSError *error) {
        //
    }];

RKObjectMapping *entryMapping = [RKObjectMapping requestMapping];
        [entryMapping addAttributeMappingsFromDictionary:[SingleEntry attributesMapping]];
        RKObjectMapping *entrySerializedMapping = [entryMapping inverseMapping];

    RKRelationshipMapping *entryRelationship = [RKRelationshipMapping relationshipMappingFromKeyPath:@"entries" toKeyPath:@"values" withMapping:entrySerializedMapping];

    RKObjectMapping *valueMapping = [RKObjectMapping requestMapping];

    [valueMapping addPropertyMapping:valueMapping];

    RKRequestDescriptor *descriptor = [RKRequestDescriptor requestDescriptorWithMapping:valueMapping objectClass:[EntriesCollection class] rootKeyPath:nil];

    [self.objectManager addRequestDescriptor:descriptor];
    self.objectManager.requestSerializationMIMEType = RKMIMETypeJSON;

    NSString *path = [self pathForPOST];

    [self.objectManager postObject:entryCollection path:path parameters:nil success:nil failure:nil];
