Restkit Get with Params & Block with Shared Client

问题

It won't let me attached the params to the request, what am I doing wrong? Params is a Dictionary and endString adds to the sharedClient baseURL.

[[RKClient sharedClient] get:endString usingBlock:^(RKRequest *loader){
    loader.params = [RKParams paramsWithDictionary:params];
    loader.onDidLoadResponse = ^(RKResponse *response) {

        [self parseJSONDictFromResponse:response];
    };


    loader.onDidFailLoadWithError = ^(NSError *error) {
        NSLog(@"error2:%@",error);
    };
}];

I get this error:RestKit was asked to retransmit a new body stream for a request. Possible connection error or authentication challenge?

I think you are on the right track. Below is from a working example I found here, about 2/3 the way down the page. Another option for you may be to append the params directly to the URL. I'm not sure if that's feasible for you, but if your parameters are simple then it may be.

- (void)authenticateWithLogin:(NSString *)login password:(NSString *)password onLoad:(RKRequestDidLoadResponseBlock)loadBlock onFail:(RKRequestDidFailLoadWithErrorBlock)failBlock
{
    [[RKClient sharedClient] post:@"/login" usingBlock:^(RKRequest *request) {
        request.params = [NSDictionary dictionaryWithKeysAndObjects:
                          @"employee[email]", login,
                          @"employee[password]", password,
                          nil];
        request.onDidLoadResponse = ^(RKResponse *response) {

            id parsedResponse = [response parsedBody:NULL];
            NSString *token = [parsedResponse valueForKey:@"authentication_token"];
            //NSLog(@"response: [%@] %@", [parsedResponse class], parsedResponse);

            if (token.length > 0) {
                NSLog(@"response status: %d, token: %@", response.statusCode, token);
                [[RKClient sharedClient] setValue:token forHTTPHeaderField:@"X-Rabatme-Auth-Token"];

                if (loadBlock) loadBlock(response);
            }

            [self fireErrorBlock:failBlock onErrorInResponse:response];
        };
        request.onDidFailLoadWithError = failBlock;
    }];
}
