Question

现在,我正在对我的代码做一个巨大的重新构思,我想统一我使用雷斯基特的方式。我已经将RPC的通话方式与我的API服务器和REST的通话方式区分开来。

使用物体绘图和 RPC 调用RKClient 调用RCC。此外,我使用街区而不是代表,这是件好事,但我对它如何运作有些怀疑。

这是我之前的代码, 它很好地张贴了对象, 并用代表手动绘制地图, 之后是使用不发送参数的区块的新代码。

//This was the old way...
- (void) upload: (KFMedia *) pic {

    RKParams* imageParams = [RKParams params];
    NSData* imageData = UIImageJPEGRepresentation(pic.image, 0.7f);
    [imageParams setData:imageData MIMEType:@"image/jpg" forParam:@"FileUpload"];

    [[RKClient sharedClient] post:@"/api/upload/" params:imageParams delegate:self]; 

}

//This is the new way I m trying...
- (void) upload: (KFMedia *) pic onLoad:(RKObjectLoaderDidLoadObjectBlock) loadBlock onError:(RKRequestDidFailLoadWithErrorBlock)failBlock{

    RKParams* imageParams = [RKParams params];
    NSData* imageData = UIImageJPEGRepresentation(pic.image, 0.7f);
    [imageParams setData:imageData MIMEType:@"image/jpg" forParam:@"FileUpload"];

    [[RKObjectManager sharedManager] loadObjectsAtResourcePath:@"/api/upload/" usingBlock:^(RKObjectLoader *loader) {

        //Trying to set params here, but it seems that I m not sending anything :(
        loader.params = imageParams;
        loader.objectMapping = [[RKObjectManager sharedManager].mappingProvider objectMappingForClass:[KFMedia class]];
        loader.delegate = self;
        loader.onDidLoadObject = loadBlock;
        loader.onDidFailWithError = failBlock;
        loader.onDidFailLoadWithError = failBlock;
        loader.onDidLoadResponse = ^(RKResponse *response) {
            [self fireErrorBlock:failBlock onErrorInResponse:response];
        };

    }];

}

我发送的请求是空的,这意味着参数没有被正确发送或设置。对于如何使参数发挥作用有什么想法?

我刚刚解决了问题。要发送加载的附加参数ObjectsAtResourtPath 您必须强制使用

loader.method = RKRequestMethodPOST;

该守则如下:

- (void) upload: (KFMedia *) pic onLoad:(RKObjectLoaderDidLoadObjectBlock) loadBlock onError:(RKRequestDidFailLoadWithErrorBlock)failBlock{

    RKParams* imageParams = [RKParams params];
    NSData* imageData = UIImageJPEGRepresentation(pic.image, 0.7f);
    [imageParams setData:imageData MIMEType:@"image/jpg" forParam:@"FileUpload"];

    [[RKObjectManager sharedManager] loadObjectsAtResourcePath:@"/api/upload/" usingBlock:^(RKObjectLoader *loader) {

        loader.method = RKRequestMethodPOST; //This line solved the problem
        loader.params = imageParams;
        loader.objectMapping = [[RKObjectManager sharedManager].mappingProvider objectMappingForClass:[KFMedia class]];
        loader.delegate = self;
        loader.onDidLoadObject = loadBlock;
        loader.onDidFailWithError = failBlock;
        loader.onDidFailLoadWithError = failBlock;
        loader.onDidLoadResponse = ^(RKResponse *response) {
            [self fireErrorBlock:failBlock onErrorInResponse:response];
        };

    }];

}
