NSURL is (null)

有次在做client跟server的溝通使用ASIHTTPRequest做資料傳輸

卻發現

什麼都沒作用直接

- (void)requestFailed:(ASIHTTPRequest *)request

還跑去叫server的人來看php為什麼資料會吐不出來

也跑了error的錯誤來看

Error Error Domain=ASIHTTPRequestErrorDomain Code=5 "Unable to create request (bad url?)" UserInfo=0x8b599e0 {NSLocalizedDescription=Unable to create request (bad url?)}

後來仔細檢測

發現再

NSString to NSURL這邊出了問題而且很奇怪的是

一個中文字不會出現這樣的問題真是妙了

NSString *url_str = [NSString stringWithFormat:@"%@%@&Keyword=%@", area_cate_poi_str, AppDelegate.lag_id, searchbar.text]; NSLog(@"getPoiServer url_str is %@", url_str); NSURL *url = [NSURL URLWithString:url_str]; NSLog(@"url is %@", url); ASIHTTPRequest *request_poi = [ASIHTTPRequest requestWithURL:url]; [request_poi setDelegate:self]; [request_poi startAsynchronous];

後來發現NSString to NSURL會發生這樣的狀況 才知道是本身語法的問題跟sever沒關係 後來才知道要先幫NSString轉成UTF8格式
NSString *url_str = [NSString stringWithFormat:@"%@%@&Keyword=%@", area_cate_poi_str, AppDelegate.lag_id, searchbar.text]; url_str = [url_str stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding]; NSURL *url = [NSURL URLWithString:url_str]; NSLog(@"url url_str is %@", url); ASIHTTPRequest *request_poi = [ASIHTTPRequest requestWithURL:url]; [request_poi setDelegate:self]; [request_poi startAsynchronous];
