NSURLConnection-中文URL处理

如果url中直接有中文，而不做任何处理的话，不会解析，返回为空。需要转码。

// 将中文URL进行转码
    urlStr = [urlStr stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding];

GET

- (void)get
{
    // 0.请求路径
    NSString *urlStr = @"http://120.25.226.186:32812/login2?username=小码哥&pwd=520it";
    // 将中文URL进行转码
    urlStr = [urlStr stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding];
    NSURL *url = [NSURL URLWithString:urlStr];
    
    // 1.创建请求对象
    NSURLRequest *request = [NSURLRequest requestWithURL:url];
    
    // 2.发送请求
    [NSURLConnection sendAsynchronousRequest:request queue:[[NSOperationQueue alloc] init] completionHandler:^(NSURLResponse *response, NSData *data, NSError *connectionError) {
        // 3.解析服务器返回的数据（解析成字符串）
        NSString *string = [[NSString alloc] initWithData:data encoding:NSUTF8StringEncoding];
        NSLog(@"%@", string);
    }];
}

POST

- (void)post
{
    // 0.请求路径
    NSString *urlStr = @"http://120.25.226.186:32812/login2";
    NSURL *url = [NSURL URLWithString:urlStr];
    
    // 1.创建请求对象
    NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:url];
    request.HTTPMethod = @"POST";
    request.HTTPBody = [@"username=小码哥&pwd=520it" dataUsingEncoding:NSUTF8StringEncoding];
    
    // 2.发送请求
    [NSURLConnection sendAsynchronousRequest:request queue:[[NSOperationQueue alloc] init] completionHandler:^(NSURLResponse *response, NSData *data, NSError *connectionError) {
        // 3.解析服务器返回的数据（解析成字符串）
        NSString *string = [[NSString alloc] initWithData:data encoding:NSUTF8StringEncoding];
        NSLog(@"%@", string);
    }];
}
