URL GET/POST 请求 Objective-c
我必须
<?php
if(@$_GET['option']) {
echo "You said \"{$_GET['option']}\"";
}else if(@$_POST['option']) {
echo "You said \"{$_POST['option']}\"";
}
?>
使用此代码向 localhost: ive 发送 get 或 post 请求：
NSURLRequest *request = [NSURLRequest requestWithURL:[NSURL URLWithString:@"http://localhost/wsh/index.php?option=Hello"]];
NSData *response = [NSURLConnection sendSynchronousRequest:request returningResponse:nil error:nil];
NSString *get = [[NSString alloc] initWithData:response encoding:NSUTF8StringEncoding];
它可以工作，但在代码中一次。如果我再做一次，应用程序就会终止。
我尝试使用 ASIFormDataRequest：
ASIFormDataRequest *request = [[[ASIFormDataRequest alloc] initWithURL:@"http://localhost/wsh/index.php"] autorelease];
[request setPostValue:@"option" forKey:@"myFormField1"];
[request start];
NSError *error = [request error];
if (!error) {
NSString *response = [request responseString];
NSLog(response);
}else{
NSLog(@"error");
}
它说：
2010-01-07 13:20:34.964 WSH[3351:903] -[NSCFString absoluteURL]: unrecognized selector sent to instance 0x160f8
2010-01-07 13:20:34.966 WSH[3351:903] error
对不起我的英语
I have to send get or post request to localhost:
<?php
if(@$_GET['option']) {
echo "You said \"{$_GET['option']}\"";
}else if(@$_POST['option']) {
echo "You said \"{$_POST['option']}\"";
}
?>
ive using this code:
NSURLRequest *request = [NSURLRequest requestWithURL:[NSURL URLWithString:@"http://localhost/wsh/index.php?option=Hello"]];
NSData *response = [NSURLConnection sendSynchronousRequest:request returningResponse:nil error:nil];
NSString *get = [[NSString alloc] initWithData:response encoding:NSUTF8StringEncoding];
it works, but one time in code. if ill do it another one time, application has terminate.
Im try to use ASIFormDataRequest:
ASIFormDataRequest *request = [[[ASIFormDataRequest alloc] initWithURL:@"http://localhost/wsh/index.php"] autorelease];
[request setPostValue:@"option" forKey:@"myFormField1"];
[request start];
NSError *error = [request error];
if (!error) {
NSString *response = [request responseString];
NSLog(response);
}else{
NSLog(@"error");
}

2010-01-07 13:20:34.964 WSH[3351:903] -[NSCFString absoluteURL]: unrecognized selector sent to instance 0x160f8
2010-01-07 13:20:34.966 WSH[3351:903] error

您正在使用纯
NSString文字，其中需要NSURL对象： [...]initWithURL:@"http://localhost/wsh/index.html php"[...]将其更改为
initWithURL:[NSURL URLWithString:@"http://localhost/wsh/index.php"]。You are using a plain
NSStringliteral where anNSURLobject is expected: [...]initWithURL:@"http://localhost/wsh/index.php"[...]Change this to
initWithURL:[NSURL URLWithString:@"http://localhost/wsh/index.php"].我想知道您是否还应该切换后值的值和键，即将行更改
为
I wonder if also you should switch the value and key for the post values, ie change the line
to
