RESTKit POST请求教程 [英] RESTKit POST Request Tutorial

问题描述

我想知道是否有关于如何使用RESTKit进行POST请求的特定教程.我看过一些教程，但没有发现任何这样的内容:这正是您使用RESTKit进行POST请求的方式."非常感谢您的帮助.

I would like to know if there is a specific tutorial on how to do a POST request with RESTKit. I have looked at some tutorials but I haven't found any that say, "This is exactly how you do a POST request with RESTKit." Help is much appreciated.

推荐答案

假设您已经有一个映射模型，您可以简单地执行以下操作:

Assuming you already have a mapped model, you can simply perform this:

首先，假设您的映射中有一个，则用responseDescriptor的inverseMapping设置requestDescriptor.

First, set a requestDescriptor with the inverseMapping of your responseDescriptor, assuming you have one with your mapping.

//This is used for mapping responses, you already should have one of this. PS:[Data mapping] is a method that returns an RKObjectMapping for my model. You should create yours or use a previous created one
RKResponseDescriptor *responseDescriptor = [RKResponseDescriptor responseDescriptorWithMapping:[Data mapping] pathPattern:nil keyPath:@"data" statusCodes:statusCodeSet];
[[RKObjectManager sharedInstance] addResponseDescriptor:responseDescriptor];

//Inverse mapping, to perform a POST
RKRequestDescriptor *requestDescriptor = [RKRequestDescriptor requestDescriptorWithMapping:[[Data mapping] inverseMapping]  objectClass:[Data class] rootKeyPath:nil];
[[RKObjectManager sharedInstance] addRequestDescriptor:requestDescriptor];

在那之后，要执行POST，只需简单地调用下面的方法. Restkit将获取您尝试发布的实例，对其进行序列化并发送到所选的路径.

After that, to perform a POST, just simply call the method below. Restkit will get the instance that you are trying to post, serialize it and send to the path chosen.

[[RKObjectManager sharedInstance] postObject:instanceOfYourModel path:yourPathHere parameters:nil success:^(RKObjectRequestOperation *operation, RKMappingResult *mappingResult) {
    NSLog(@"Success");

} failure:^(RKObjectRequestOperation *operation, NSError *error) {
    NSLog(@"Error");
}];

如果您没有映射的模型，请告诉我，以便我们可以尝试其他尝试.

If you don't have a mapped model, let me know so we can try something else.
