你想通过 Http
协议向服务器发送一个 Get
的包装请求,并在这个请求中添加了一些请
求参数.
向远程服务器发送一个
GET
请求,然后解析返回的数据。通常一个 GET
请求是添加了
一些参数的,这些参数一般是添加在 URL
请求中。
我准备了一个 GET
形式的 webservice
接口,你可以通过 http://pixolity.com/get.php
来进
行请求。
/* URL = http://pixolity.com/get.php?param1=First¶m2=Second */ NSString *urlAsString = @"http://pixolity.com/get.php";
urlAsString = [urlAsString stringByAppendingString:@"?param1=First"]; urlAsString = [urlAsString stringByAppendingString:@"¶m2=Second"];
NSURL *url = [NSURL URLWithString:urlAsString];
NSMutableURLRequest *urlRequest = [NSMutableURLRequest requestWithURL:url]; [urlRequest setTimeoutInterval:30.0f];
[urlRequest setHTTPMethod:@"GET"];
NSOperationQueue *queue = [[NSOperationQueue alloc] init];
[NSURLConnection sendAsynchronousRequest:urlRequest queue:queue completionHandler:^(NSURLResponse *response,

NSData *data, NSError *error) {
if ([data length] >0 && error == nil){
NSString *html = [[NSString alloc] initWithData:data encoding:NSUTF8StringEncoding];
NSLog(@"HTML = %@", html); }
else if ([data length] == 0 && error == nil){
NSLog(@"Nothing was downloaded."); }
else if (error != nil){
NSLog(@"Error happened = %@", error);
} }];
post请求：
NSString *urlAsString = @"http://pixolity.com/post.php";
urlAsString = [urlAsString stringByAppendingString:@"?param1=First"];
urlAsString = [urlAsString stringByAppendingString:@"¶m2=Second"];
NSURL *url = [NSURL URLWithString:urlAsString];
NSMutableURLRequest *urlRequest = [NSMutableURLRequest requestWithURL:url]; [urlRequest setTimeoutInterval:30.0f];
[urlRequest setHTTPMethod:@"POST"];
NSString *body = @"bodyParam1=BodyValue1&bodyParam2=BodyValue2"; [urlRequest setHTTPBody:[body dataUsingEncoding:NSUTF8StringEncoding]]; NSOperationQueue *queue = [[NSOperationQueue alloc] init];
[NSURLConnection sendAsynchronousRequest:urlRequest queue:queue completionHandler:^(NSURLResponse *response,
NSData *data, NSError *error) {
if ([data length] >0 && error == nil){
NSString *html = [[NSString alloc] initWithData:data encoding:NSUTF8StringEncoding];
NSLog(@"HTML = %@", html); }
else if ([data length] == 0 && error == nil){
NSLog(@"Nothing was downloaded."); }
else if (error != nil){
NSLog(@"Error happened = %@", error);
} }];
delete请求：
NSString *urlAsString = @"http://pixolity.com/delete.php";
urlAsString = [urlAsString stringByAppendingString:@"?param1=First"];
urlAsString = [urlAsString stringByAppendingString:@"¶m2=Second"];
NSURL *url = [NSURL URLWithString:urlAsString];
NSMutableURLRequest *urlRequest = [NSMutableURLRequest requestWithURL:url];
[urlRequest setTimeoutInterval:30.0f];
[urlRequest setHTTPMethod:@"DELETE"];
NSString *body = @"bodyParam1=BodyValue1&bodyParam2=BodyValue2";
[urlRequest setHTTPBody:[body dataUsingEncoding:NSUTF8StringEncoding]];
NSOperationQueue *queue = [[NSOperationQueue alloc] init];
[NSURLConnection sendAsynchronousRequest:urlRequest queue:queue completionHandler:
^(NSURLResponse *response, NSData *data, NSError *error) {
if ([data length] >0 && error == nil){
NSString *html = [[NSString alloc] initWithData:data encoding:NSUTF8StringEncoding];
NSLog(@"HTML = %@", html); }
else if ([data length] == 0 && error == nil){
NSLog(@"Nothing was downloaded."); }
else if (error != nil){
NSLog(@"Error happened = %@", error);
} }];
put请求：
NSString *urlAsString=@"http://pixolity.com/put.php";
urlAsString=[urlAsString stringByAppendingString:@"?param1=First"];
urlAsString=[urlAsString stringByAppendingString:@"¶m2=Second"];
NSURL *url=[NSURL URLWithString:urlAsString];
NSMutableURLRequest *urlRequest=[NSMutableURLRequest requestWithURL:url];
[urlRequest setTimeoutInterval:30.0f];
[urlRequest setHTTPMethod:@"PUT"];
NSString *body=@"bodyParaml=BodyValuel&bodyParam2=BodyValue2";
[urlRequest setHTTPBody:[body dataUsingEncoding:NSUTF8StringEncoding]];
NSOperationQueue *queue=[[NSOperationQueue alloc] init];
[NSURLConnection sendAsynchronousRequest:urlRequest queue:queue completionHandler:^(NSURLResponse *response, NSData *data, NSError *error) {
if ([data length]>0&&error==nil) {
NSString *html=[[NSString alloc] initWithData:data encoding:NSUTF8StringEncoding];
NSLog(@"HTML=%@",html);
}else if([data length]==0&&error==nil){
NSLog(@"Nothing was downLoaded.");
}else if(error!=nil){
NSLog(@"Error Happened=%@",error);
}
}];
