iOS开发-url包含中文报错解决办法

经常, 我们用通过这样的方法调用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, 当路径中存在中文的时候. ASI就无法正常访问那个url。

报错如下:

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

解决办法:

转码.

	urlString = [urlString stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding];

完整代码:

    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];
