Question

NSMutableURLRequest* post = [NSMutableURLRequest requestWithURL: [NSURL URLWithString:   @"http://test.com/upload.php"]];

  [post setHTTPMethod: @"POST"];


  NSString *boundary = [NSString stringWithString:@"---------------------------     3587343183674357"];

NSString *contentType = [NSString stringWithFormat:@"multipart/form-data; boundary=%@",boundary];

[post addValue:contentType forHTTPHeaderField: @"Content-Type"];


body = [NSMutableData data];

[body appendData:[[NSString stringWithFormat:@"\r\n--%@\r\n",boundary] dataUsingEncoding:NSUTF8StringEncoding]];

[body appendData:[[NSString stringWithString:@"Content-Disposition: form-data; name=\"textfile\"; filename=\"test.txt\"\r\n"] dataUsingEncoding:NSUTF8StringEncoding]];

[body appendData:[[NSString stringWithString:@"Content-Type: application/multipart/form-data \r\n\r\n"] dataUsingEncoding:NSUTF8StringEncoding]];


 NSString* str= @"teststring";
NSData* data=[str dataUsingEncoding:NSUTF8StringEncoding];
[body appendData:data];

[body appendData:[[NSString stringWithFormat:@"\r\n--%@--\r\n",boundary] dataUsingEncoding:NSUTF8StringEncoding]];


[post setHTTPBody:body];

发送文本文件后，我检查我的服务器，testtring被发送并附加为参数的一部分。不，实际上我希望它位于名为test.txt的文件中，并且位于目录中。那么如何将数据作为test.txt文件发送到目录中呢？我不希望它只是参数的一部分吗？

您要将数据写入文档目录吗？然后使用此代码...

NSString *documentsDirectory = [NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES) objectAtIndex:0];
[data writeToFile:[NSString stringWithFormat:@"%@/test.txt", documentsDirectory] atomically:YES];

IPhone HTTP Post Text Data并保存为文本文件
