objective-c - ios sdk 上传文件，怎样在swift中调用？

问题描述

问 题

   let up = UpYunFormUploader()
    let successBlocker = { (response:HTTPURLResponse,responseBody:NSDictionary) -> Void in
        
        logger.info("response body %@", responseBody)
        let url = responseBody.object(forKey:"url") as! String
        logger.info("file url：https://%@.b0.upaiyun.com/%@", CST_UPYUN_VP_BUCKET , url)
            onSuccess(url)
        } as! UpLoaderSuccessBlock
        
  编译器提示

Cast from '(HTTPURLResponse, NSDictionary) -> Void' to unrelated type 'UpLoaderSuccessBlock' (aka '(Optional<HTTPURLResponse>, Optional<Dictionary<AnyHashable, Any>>) -> ()') always fails

解决方案

successBlocker闭包与UpLoaderSuccessBlock类型不匹配
UpLoaderSuccessBlock的类型应该是(HTTPURLResponse?, [AnyHashable: Any]?) -> ()
可以修改response和responseBody的类型

let successBlocker = { (response: HTTPURLResponse?,responseBody: [AnyHashable: Any]?) -> Void in
            
    logger.info("response body %@", responseBody)
    let url = responseBody.object(forKey:"url") as! String
    logger.info("file url：https://%@.b0.upaiyun.com/%@", CST_UPYUN_VP_BUCKET , url)
    onSuccess(url)
} as! UpLoaderSuccessBlock
