NSURLRequest - 编码NSURLRequest的URL url POST Body（iPhone objective-C） [英] NSURLRequest - encode url for NSURLRequest POST Body (iPhone objective-C)

问题描述

我使用NSURLRequest发送帖子。

  NSURL * url = [NSURL URLWithString：someUrlString]; 
 NSMutableURLRequest * theRequest = [NSMutableURLRequest requestWithURL：url]; 
 NSString * msgLength = [NSString stringWithFormat：@％d，[parameterString length]]; 
 [theRequest addValue：msgLength forHTTPHeaderField：@Content-Length]; 
 [theRequest setHTTPMethod：@POST]; 
 [theRequest setHTTPBody：[parameterString dataUsingEncoding：NSUTF8StringEncoding]]; 
 

在请求正文中，我编码以下NVP：

returnURL = http://someSite.com

帖子正在成功，但我收到一个错误。

returnURL =




< http：％2F％2FsomeSite.com

同样的错误。

Todd Ditchendorf的HTTP客户端，具有相同的结果。

我知道我必须编码这个错误，有人可以告诉我我做错了什么？

感谢

**更新：
感谢那些回答。我错过了一个&符号在我的NVP值。所以当然，一旦我修复它，一切都很好。我怀疑，在身体的一个url的编码是不正确的。我不使用ASIHTTPRequest框架，但它确实帮助我解决问题（overkill我需要的）。

解决方案

请考虑使用Ben Copsey的 ASIHTTPRequest 框架用于生成和发送同步和异步HTTTP请求/ p>

  ASIFormDataRequest * request = [[[ASIFormDataRequest alloc] initWithURL：@http://someSite.com] autorelease]; 
 [request setPostValue：@myValue1forKey：@myFormField1]; 
 [request setPostValue：@myValue2forKey：@myFormField2]; 
 //等
 [request start]; 
 NSError * error = [request error]; 
 if（！error）
 NSString * response = [request responseString]; 
  

他的框架是一个巨大的节省时间。

I am sending a post using NSURLRequest.

NSURL *url = [NSURL URLWithString:someUrlString];
NSMutableURLRequest *theRequest = [NSMutableURLRequest requestWithURL:url];
NSString *msgLength = [NSString stringWithFormat:@"%d", [parameterString length]];
[theRequest addValue: msgLength forHTTPHeaderField:@"Content-Length"];
[theRequest setHTTPMethod:@"POST"];
[theRequest setHTTPBody: [parameterString dataUsingEncoding:NSUTF8StringEncoding]];

Within the body of the Request I am encoding the following NVP:

returnURL=http://someSite.com

The post is going through successfully, but I get an error back. The error states an invalid url.

So, I changed it to:

returnURL=http:%2F%2FsomeSite.com

With the same error.

I have also double checked it with Todd Ditchendorf's HTTP Client, with the same results.

I know I must be encoding this wrong can someone tell me what I am doing wrong?

Thanks Corey

**UPDATE: Thanks to those who answered. I missed an ampersand in my NVP values. So of course, as soon as I fixed it, everything was fine. What I suspectede, the encoding of a url in the body of the post was incorrect. I am not using the ASIHTTPRequest framework, but it did help me troubleshoot the problem (overkill for what I needed). **

解决方案

Consider using Ben Copsey's ASIHTTPRequest framework for generating and sending synchronous and asynchronous HTTTP requests (POST and GET):

ASIFormDataRequest *request = [[[ASIFormDataRequest alloc] initWithURL:@"http://someSite.com"] autorelease];
[request setPostValue:@"myValue1" forKey:@"myFormField1"];
[request setPostValue:@"myValue2" forKey:@"myFormField2"];
// etc.
[request start];
NSError *error = [request error];
if (!error)
  NSString *response = [request responseString];

His framework is a huge time-saver.
