常常, 我们用通过这个方案调用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];
可是, 当路径中存在中文的时候. ASI就无法正常訪问那个url。
报错例如以下:
Error Domain=ASIHTTPRequestErrorDomain Code=5 "Unable to create request (bad url?)" UserInfo=0x109697090 {NSLocalizedDescription=Unable to create request (bad url?)}
解决的方法:
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];
