iOS与php进行简单的post交互

最近研究了一下这方面的知识,现在贴出代码做一个总结

首先是iOS端的

- (void)viewDidLoad{    [super viewDidLoad];        mydata = [[NSMutableData alloc]initWithCapacity:0];    NSURL *url = [NSURL URLWithString:@"http://localhost/test/postDemo.php"];        //创建请求    NSMutableURLRequest *request = [[NSMutableURLRequest alloc]initWithURL:url cachePolicy:NSURLRequestUseProtocolCachePolicy timeoutInterval:60];        [request setHTTPMethod:@"POST"];        NSNumber *s = [NSNumber numberWithInt:22];        NSMutableDictionary *dict = [[NSMutableDictionary alloc]initWithObjectsAndKeys:[@"com.xinmei365.font" stringByEncodingURIComponent],@"package",s,@"version",@"11",@"channel",@"22",@"type",@"zh",@"lang", nil];        NSString *param = [dict JSONString];       NSData *data = [param dataUsingEncoding:NSUTF8StringEncoding];        //加入json参数    [request setHTTPBody:data];        NSURLConnection *contect = [[NSURLConnection alloc]initWithRequest:request delegate:self];//    [contect start];    }- (void)connection:(NSURLConnection *)connection didReceiveResponse:(NSURLResponse *)response{    mydata.length = 0;}- (void)connection:(NSURLConnection *)connection didReceiveData:(NSData *)data  {    [mydata appendData:data];}- (void)connectionDidFinishLoading:(NSURLConnection *)connection{    NSString *str = [[NSString alloc]initWithData:mydata encoding:NSUTF8StringEncoding];    NSDictionary *dict = [str objectFromJSONString];    NSLog(@"%@",dict);    }- (void)connection:(NSURLConnection *)connection didFailWithError:(NSError *)error{    NSLog(@"error");}

下面是php,相当于传上去,再传回来

<?php if (!empty($GLOBALS['HTTP_RAW_POST_DATA']))    {        $command =  isset($GLOBALS['HTTP_RAW_POST_DATA']) ? $GLOBALS['HTTP_RAW_POST_DATA'] : file_get_contents("php://input");        $j = json_decode($command,TRUE);//true,转化成数组    }        echo json_encode($j);

注意:先设置php.ini中的always_populate_raw_post_data值设为On,这样表示可以接受data数据(这个php.ini是隐藏在etc目录下的,一般的搜索可能也许也搜索不到,需要自己用终端搞定这个问题,如果没有设置的话,可以参考下面的代码)

if (!empty($GLOBALS['HTTP_RAW_POST_DATA']))    {        $command =  isset($GLOBALS['HTTP_RAW_POST_DATA']) ? $GLOBALS['HTTP_RAW_POST_DATA'] : file_get_contents("php://input");        $j = json_decode($command,TRUE);        echo json_encode($j);    }else if(file_get_contents("php://input")){        $command = file_get_contents("php://input");        $j = json_decode($command,TRUE);        echo json_encode($j);    }else{        echo json_encode("error!!!!!!!!!");    }
