在Objective-C中简单的http post示例？ [英] Simple http post example in Objective-C?

问题描述

我有一个需要登录（用户名和密码）的php网页。我有用户输入信息进入应用程序很好..但我需要一个例子，如何做一个POST请求到网站。支持网站上的苹果示例是相当复杂的显示图片上传..我应该更简单..我只想发布2行文字..
任何人都有什么好的例子？

I have a php webpage that requires a login (userid & password). I have the user enter the information into the app just fine.. but I need an example on how to do a POST request to a website. The apple example on the support site is rather complicated showing a picture upload.. mine should be simpler.. I just want to post 2 lines of text.. Anyone have any good examples?

推荐答案

NSString *post = @"key1=val1&key2=val2";
NSData *postData = [post dataUsingEncoding:NSASCIIStringEncoding allowLossyConversion:YES];

NSString *postLength = [NSString stringWithFormat:@"%d", [postData length]];

NSMutableURLRequest *request = [[[NSMutableURLRequest alloc] init] autorelease];
[request setURL:[NSURL URLWithString:@"http://www.nowhere.com/sendFormHere.php"]];
[request setHTTPMethod:@"POST"];
[request setValue:postLength forHTTPHeaderField:@"Content-Length"];
[request setValue:@"application/x-www-form-urlencoded" forHTTPHeaderField:@"Content-Type"];
[request setHTTPBody:postData];

这是我最近使用的，它对我来说很好。
