iOS UIWebView如何加载POST，GET请求，传递参数

• POST请求传参：

NSMutableURLRequest *request = [[NSMutableURLRequest alloc] initWithURL:[NSURL URLWithString:self.urlStr]];
NSString *requestBody = [NSString stringWithFormat:@"uid=%@",@"123"];
    
[request setHTTPMethod:@"POST"];
[request setHTTPBody:[requestBody dataUsingEncoding:NSUTF8StringEncoding]];
[self.webView loadRequest:request];

• GET请求传参

NSString *urlStr = @"https://www.baidu.com?uid=lj&pwd=123";
NSURL *url = [NSURL URLWithString:urlStr];
NSURLRequest *request = [NSURLRequest requestWithURL:url];
[self.webView loadRequest:request];
