HTTP 请求未设置内容长度

我正在尝试使用 Google Data API 在某些地方上传 CSV 文件。

我有这段代码：

NSMutableURLRequest *request = [[NSMutableURLRequest alloc] initWithURL:[NSURL URLWithString:direccion]];

NSMutableURLRequest *request = [[NSMutableURLRequest alloc] initWithURL:[NSURL URLWithString:direccion]];

NSData *postData = [creacionCSV dataUsingEncoding:NSASCIIStringEncoding allowLossyConversion:YES];
NSString *postLength = [NSString stringWithFormat:@"%d",[postData length]];
[request setValue:postLength forHTTPHeaderField:@"Content-Length"];
[request setValue:@"2.0" forHTTPHeaderField:@"GData-Version"];
[request setValue:@"application/vnd.google-earth.kml+xml" forHTTPHeaderField:@"Content-Type"];
[request setValue:@"Mapa de prueba" forHTTPHeaderField:@"Slug"];
[request setHTTPBody:postData];
[request setHTTPMethod:@"POST"];

NSData *datosRecibidos;
datosRecibidos = [NSURLConnection sendSynchronousRequest:request returningResponse:nil error:nil];
NSString *token = [[NSString alloc] initWithData:datosRecibidos encoding:NSASCIIStringEncoding];
NSLog(@"%@",token);

其中 creacionCSV 是包含所有 KML 代码的 NSString。执行后，我从服务器获得了这个答案：

<html lang=en>
  <meta charset=utf-8>
  <title>Error 411 (Length Required)!!1</title>
  <style> [...] </style>
  <a href=//www.google.com/ id=g><img src=//www.google.com/images/logo_sm.gif alt=Google></a>
  <p><b>411.</b> <ins>That’s an error.</ins>
  <p>POST requests require a <code>Content-length</code> header.  
  <ins>That’s all we know.</ins>

所以我收到了 411 错误。我检查了标题，它既不为零也不为空。为什么我的帖子没有采用该标头？

非常感谢！

I'm trying to use Google Data API to upload a CSV file with some places.

I've this piece of code:

NSMutableURLRequest *request = [[NSMutableURLRequest alloc] initWithURL:[NSURL URLWithString:direccion]];

NSMutableURLRequest *request = [[NSMutableURLRequest alloc] initWithURL:[NSURL URLWithString:direccion]];

NSData *postData = [creacionCSV dataUsingEncoding:NSASCIIStringEncoding allowLossyConversion:YES];
NSString *postLength = [NSString stringWithFormat:@"%d",[postData length]];
[request setValue:postLength forHTTPHeaderField:@"Content-Length"];
[request setValue:@"2.0" forHTTPHeaderField:@"GData-Version"];
[request setValue:@"application/vnd.google-earth.kml+xml" forHTTPHeaderField:@"Content-Type"];
[request setValue:@"Mapa de prueba" forHTTPHeaderField:@"Slug"];
[request setHTTPBody:postData];
[request setHTTPMethod:@"POST"];

NSData *datosRecibidos;
datosRecibidos = [NSURLConnection sendSynchronousRequest:request returningResponse:nil error:nil];
NSString *token = [[NSString alloc] initWithData:datosRecibidos encoding:NSASCIIStringEncoding];
NSLog(@"%@",token);

Where creacionCSV is an NSString with all the KML code.
Once executed, I've obtained this answe from server:

<html lang=en>
  <meta charset=utf-8>
  <title>Error 411 (Length Required)!!1</title>
  <style> [...] </style>
  <a href=//www.google.com/ id=g><img src=//www.google.com/images/logo_sm.gif alt=Google></a>
  <p><b>411.</b> <ins>That’s an error.</ins>
  <p>POST requests require a <code>Content-length</code> header.  
  <ins>That’s all we know.</ins>

So I'm getting that 411 Error. I've checked the header and it's not nil nor empty. Why is not taking that header my POST?

Many thanks!
