Question

我刚刚开始使用RestKit，并且在Rk 0.20上线时已经到了，文档和演示是落后的。网上的大多数内容都是0.10卢比，而且0.20版本有很大的变化。

当新版本即将启动并运行时，我不想回到早期版本。

我在URL“test.myserver.com”上有一个JSON资源，它返回一个简单的数据报 - { “id_user”：“4401”， “datalocation”：“4401”， “国家”：“英国”， “数据”：“testdata”， “登录”：“Fred Bloggs”， “password”：“579c0cb0ed2dc25db121283f7a98cc71”， “accessLevel”：“2”， “timestamp”：“1012”， “datahash”：“2749da29f20ce7a85092323f193adee8” }

我很确定我已经对Mappings等进行了排序，但我的服务需要身份验证，因此我需要将请求中的用户名和密码传递给服务器。

到目前为止我已经知道了

NSURL *url = [NSURL URLWithString:@"http://test.myserver.com"];
NSURLRequest *request = [NSURLRequest requestWithURL:url];
RKObjectRequestOperation *objectRequestOperation = [[RKObjectRequestOperation alloc] initWithRequest:request responseDescriptors:@[ responseDescriptor ]];

[objectRequestOperation setCompletionBlockWithSuccess:^(RKObjectRequestOperation *operation, RKMappingResult *mappingResult) {
RKLogInfo(@"Load collection of Articles: %@", mappingResult.array);
} failure:^(RKObjectRequestOperation *operation, NSError *error) {
RKLogError(@"Operation failed with error: %@", error);
}];

         [objectRequestOperation start];

似乎与服务器联系但不可避免地记录以下错误

restkit.network:RKObjectRequestOperation.m:296对象请求失败：基础HTTP请求操作失败，错误：错误Domain = org.restkit.RestKit.ErrorDomain Code = -1011“预期状态代码在（200-299），得到401“UserInfo = 0x7884030 {NSLocalizedRecoverySuggestion = { “错误”：{ “代码”：401， “message”：“未经授权：需要验证” } }，AFNetworkingOperationFailingURLRequestErrorKey = http：//elancovision.umfundi.com> ;, NSErrorFailingURLKey = http://elancovision.umfundi.com，NSLocalizedDescription =（200-299）中的预期状态代码，获得401，AFNetworkingOperationFailingURLResponseErrorKey =}

问题当然是我如何在请求中添加用户名和密码。

抱歉这个noob问题！

Answer 1

使用基本HTTP身份验证时，应在每个请求的HTTP请求授权头字段中插入用户名和密码。

首先，我建议您使用RKObjectManager来集中请求和映射的配置。 http://restkit.org/api/latest/Classes/RKObjectManager.html RKObjectManager可以存储网络参数（通过AFNetworking Library），然后根据用户名/密码，路径，对象映射构建适当的http查询。

调整你的例子，它会给出类似的东西：

NSURL* url = [[NSURL alloc]initWithString:@"http://test.myserver.com"];
RKObjectManager* objectManager = [RKObjectManager managerWithBaseURL:url];
[objectManager.HTTPClient setAuthorizationHeaderWithUsername:@"username" password:@"password"];

//NSURLRequest *request = [NSURLRequest requestWithURL:url];
NSURLRequest *request = [objectManager requestWithObject:nil method:RKRequestMethodGET path:@"/yourAPI/yourmethod" parameters:nil];

RKObjectRequestOperation *objectRequestOperation = [[RKObjectRequestOperation alloc] initWithRequest:request responseDescriptors:@[ responseDescriptor ]];

[objectRequestOperation setCompletionBlockWithSuccess:^(RKObjectRequestOperation *operation, RKMappingResult *mappingResult) {
        RKLogInfo(@"Load collection of Articles: %@", mappingResult.array);
    } failure:^(RKObjectRequestOperation *operation, NSError *error) {
        RKLogError(@"Operation failed with error: %@", error);
    }];

[objectRequestOperation start];

如果身份验证有效，那么查看RESTKit wiki应该会为您提供构建正确映射的下一个提示：https://github.com/RestKit/RestKit/wiki/Object-mapping

我的解决方案：

// Build a RestKit manager object to look after the restful stuff
RKObjectManager *manager =  [RKObjectManager managerWithBaseURL:[NSURL URLWithString:@"http://test.myserver.com"]];;

// Hash the GUI input password string and pass the username in plain text
NSString *md5PW = [umfundiCommon md5:passwordField.text];           
[manager.HTTPClient setAuthorizationHeaderWithUsername:userField.text password:md5PW];

RKObjectMapping *WebResponse = [RKObjectMapping mappingForClass:[WSObject class]];

        [WebResponse addAttributeMappingsFromDictionary:@{@"id_user":@"id_user", @"datalocation": @"datalocation", @"country":@"country", @"data": @"data", @"login": @"login", @"password": @"password", @"accessLevel": @"accessLevel", @"timestamp": @"timestamp", @"datahash": @"datahash"}];

RKResponseDescriptor *responseDescriptor = [RKResponseDescriptor responseDescriptorWithMapping:WebResponse pathPattern:nil keyPath:nil statusCodes:RKStatusCodeIndexSetForClass(RKStatusCodeClassSuccessful)];
// Add the above response descriptor to the manager
[manager addResponseDescriptor:responseDescriptor];

// the getObject makes the call using the stuff assembled into the manager Object and drops into either the success or the failure routines.
[manager getObject:nil path:@"" parameters:nil success:^(RKObjectRequestOperation *operation, RKMappingResult *result)
{
NSLog (@"Server WS call success:");

NSArray *theresults = [result array];              
for (WSObject *item in theresults) {
    NSLog(@"datahash=%@",item.datahash);
    NSLog(@"user_id=%@",item.id_user);
    }
}  failure:^(RKObjectRequestOperation * operation, NSError * error)
    {
    NSLog (@"Server WS call failure: operation: %@ \n\nerror: %@", operation, error);
    }];
