iOS開發-url包含中文報錯解決辦法

標籤：des   style   blog   class   code   tar   

經常, 我們用通過這樣的方法調用API。

    NSString* urlString = [NSString stringWithFormat:@"http://api.douban.com/v2/movie/search?q=%@", content];        NSURL *url = [NSURL URLWithString:urlString];    testRequest = [ASIHTTPRequest requestWithURL:url];    [testRequest setDelegate:self];    [testRequest startAsynchronous];

但是, 當路徑中存在中文的時候. ASI就無法正常訪問那個url。

報錯如下:

Error Domain=ASIHTTPRequestErrorDomain Code=5 "Unable to create request (bad url?)" UserInfo=0x109697090 {NSLocalizedDescription=Unable to create request (bad url?)}

解決辦法:

轉碼.

urlString = [urlString stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding];

完整代碼:

    NSString* urlString = [NSString stringWithFormat:@"http://api.douban.com/v2/movie/search?q=%@", content];        urlString = [urlString stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding];    NSURL *url = [NSURL URLWithString:urlString];    testRequest = [ASIHTTPRequest requestWithURL:url];    [testRequest setDelegate:self];    [testRequest startAsynchronous];
