iphone - 上传pdf数据到服务器

Question

我想将我的 pdf 文件数据与一些用户数据(如 userId 和文件名)一起发送到服务器。

我已经尝试了 2 种解决方案，但没有在后端获得 pdf 文件。即使我的文档目录中有 pdf 文件，它也能成功打开。

尝试过 1:

-(void)uploadDock{
NSString *fileName =[NSString stringWithFormat: @"%@.pdf",@"Inspection"];
    NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory,NSUserDomainMask, YES);
    NSString *documentsDirectory = [paths objectAtIndex:0];
    NSString *path = [documentsDirectory stringByAppendingPathComponent:fileName];
    NSData *data=[NSData dataWithContentsOfFile:path];
    NSString *content=[data base64EncodedString];
    NSUserDefaults *userDefaults = [NSUserDefaults standardUserDefaults];


if ([self.responseData retainCount]) {
    NSLog(@"Do nothing");
    [self.responseData release];
}
self.responseData=[[NSMutableData alloc]init];
NSURL *url = [NSURL URLWithString:@"http://abcgroup.delivery-projects.com:81/api/index.php?keyword=docinsert"];

//self.request = [NSMutableURLRequest requestWithURL:url
//cachePolicy:NSURLRequestUseProtocolCachePolicy timeoutInterval:60.0];

self.request = [NSMutableURLRequest requestWithURL:url];
NSLog(@"Requst %@",request);
NSString *userid=[userDefaults valueForKey:@"UIDD"];
NSString *title=fileName;
NSString *docname=fileName;
NSString *size=[NSString stringWithFormat:@"%d",[data length]];
NSString *post = [NSString stringWithFormat:@"userid=%@&title=%@&docname=%@&size=%@&content=%@",userid,title,docname,size,content];
NSData *postData = [post dataUsingEncoding:NSUTF8StringEncoding];
[self.request setHTTPMethod:@"POST"];

//NSString *POSTBoundary = [NSString stringWithFormat:@"0xKhTmLbOuNdArY"];
//[self.request addValue:[NSString stringWithFormat:@"multipart/form-data; boundary=%@\r\n", POSTBoundary] forHTTPHeaderField:@"Content-Type"];

[self.request setValue:[NSString stringWithFormat:@"%d", postData.length] forHTTPHeaderField:@"Content-Length"];
[self.request setValue:@"application/x-www-form-urlencoded charset=utf-8" forHTTPHeaderField:@"Content-Type"];
[self.request setHTTPBody:postData];
[NSURLConnection connectionWithRequest:self.request delegate:self];
}

我使用以下功能上传图片、音频和视频，稍作修改。 在此函数中，urloptions 是您要与 userId 和 fileName 等文件一起发送的查询字符串。

没有机会上传 PDF，但希望这对您有所帮助。

-(NSString *)uploadFile:(NSString *)urloptions: (NSString *) ext :(NSData *)imageData{

NSURL *url=[NSURL URLWithString:[NSString stringWithFormat:@"%@&%@",APP_URL,urloptions]];   
NSMutableURLRequest *request = [[[NSMutableURLRequest alloc] init] autorelease];
[request setURL:url];
[request setHTTPMethod:@"POST"];

NSString *boundary = [NSString stringWithString:@"---------------------------14737809831466499882746641449"];
NSString *contentType = [NSString stringWithFormat:@"multipart/form-data; boundary=%@", boundary];
[request addValue:contentType forHTTPHeaderField:@"Content-Type"];

NSMutableData *body = [NSMutableData data];
[body appendData:[[NSString stringWithFormat:@"\r\n--%@\r\n", boundary] dataUsingEncoding:NSUTF8StringEncoding]];
[body appendData:[[NSString stringWithFormat:@"Content-Disposition: form-data; name=\"formFile\"; filename=\".%@\"\r\n",ext] dataUsingEncoding:NSUTF8StringEncoding]];
[body appendData:[[NSString stringWithString:@"Content-Type: application/octet-stream\r\n\r\n"] dataUsingEncoding:NSUTF8StringEncoding]];
[body appendData:[NSData dataWithData:imageData]];
[body appendData:[[NSString stringWithFormat:@"\r\n--%@--\r\n", boundary] dataUsingEncoding:NSUTF8StringEncoding]];
[request setHTTPBody:body];

NSData *returnData = [NSURLConnection sendSynchronousRequest:request returningResponse:nil error:nil];
NSString *returnString = [[[NSString alloc] initWithData:returnData encoding:NSUTF8StringEncoding] autorelease];

//NSLog(@"%@",returnString);
return returnString ;

 //[returnString release];

}
