如何在Objective-C中通过http POST发送NSMutableDictionary [英] How to send NSMutableDictionary via http POST in Objective-C

问题描述

我有一个带有一些歌曲数据的NSMutableDictionary（例如key：Artist对象：Passion Pit），我需要将其作为http POST变量发送到服务器。我一整天都在阅读示例，无法弄清楚如何转换字典的值和键，然后将它们发送到URL。

I have an NSMutableDictionary with some song data (for example key: "Artist" object: "Passion Pit") that I need to send to a server as http POST variables. I have been reading examples all day and cannot figure out how to convert my dictionary's values and keys and then send them to a URL.

iPhone SDK是否为您提供了一种方法这样做或者是否有我应该下载的源代码？

Does the iPhone SDK give you a means of doing that or is there source code that I should be downloading?

感谢您的帮助！

推荐答案

最简单的解决方案是使用 ASIHTTPRequest 库。以下是文档中的示例：

The easiest solution is to use the ASIHTTPRequest library. Here's an example from documentation:

ASIFormDataRequest *request = [ASIFormDataRequest requestWithURL:url];
[request setPostValue:@"Ben" forKey:@"first_name"];
[request setPostValue:@"Copsey" forKey:@"last_name"];
[request setFile:@"/Users/ben/Desktop/ben.jpg" forKey:@"photo"];
