分解url转为post请求

来源：互联网发布：手机的危害数据英文编辑：程序博客网时间：2024/05/19 22:02

一些情况下，为了安全起见，我们需要把get方式的http请求处理成post方式。

比如，我们从后台拿到一个访问链接，如：http://www.test.qq.com/api/do?type=1&reason=test&flag=2

希望按如下方式发送请求：

post url：http://www.test.qq.com/api/do

post 参数：type 1

reason test

flag 2

怎么做呢，贴个比较简单的方式，直接做url分解就可以了。

-(void)approval:(NSString *)approvalUrl{    NSRange curRange = [approvalUrl rangeOfString:@"?"];    NSString *baseUrl = [approvalUrl mutableCopy];    NSString *paramStr = @"";    if (curRange.location != NSNotFound) {        baseUrl = [approvalUrl substringToIndex:curRange.location];        paramStr = [approvalUrl substringFromIndex:curRange.location+1];    }        NSURL *url = [NSURL URLWithString:[baseUrl stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding]];    NSLog(@"url is:%@", url);        NSDictionary *paramDic = [Utils parametersWithSeparator:@"=" delimiter:@"&" url:paramStr];       ASIFormDataRequest *request=[ASIFormDataRequest requestWithURL:url];    NSEnumerator *enumerator = [paramDic keyEnumerator];    id object;    while (object = [enumerator nextObject]) {        NSString *key = [NSString stringWithFormat:@"%@", object];        NSString *value = [NSString stringWithFormat:@"%@", [paramDic valueForKey:key]];        [request setPostValue:value forKey:key];    }        [request setTimeOutSeconds:5];    [request setCachePolicy:NSURLRequestReloadIgnoringCacheData];    [request setDelegate:self];    [request setDidFinishSelector:@selector(requestSuccess:)];    [request setDidFailSelector:@selector(requestError:)];    [request setValidatesSecureCertificate:NO];    [request startAsynchronous];}

当然，如果需要做更复杂的url分解，可以考虑下正则表达式，后面再研究。
