我尝试了很多方法。上传没有任何帮助。有些代码通过在模拟器中工作将视频上传到服务器。但是不要通过在设备上工作来上传服务器中的视频。请帮助我提供工作建议
我最近的代码是：
NSURL *urlvalue = [NSURL fileURLWithPath:self.videoPath];
NSLog(@"The urlvalue is = %@",urlvalue);
NSData *urldata = [NSData dataWithContentsOfURL:urlvalue];
//NSURL *fileURL = [NSURL fileURLWithPath:videoPath];
//NSLog(@"fileurl is = %@",fileURL);
//NSData *videoData1 = [videoPath dataUsingEncoding:NSUTF8StringEncoding];
//NSData *videoData1=[NSData dataWithContentsOfFile:videoPath];
NSData *videoData1=urldata;
//NSLog(@"URL FOR VIDEO = %@",videoData);
NSString *postLength = [NSString stringWithFormat:@"%d", [videoData1 length]];
NSMutableURLRequest *request = [[NSMutableURLRequest alloc] init];
[request setURL:[NSURL URLWithString:[NSString stringWithFormat:@"http://demo.xyzxyzxyz.com/client/vine-clone/mobile/video_upload"]]];
[request setHTTPMethod:@"POST"];
[request setTimeoutInterval:60000];
NSString *boundary = [NSString stringWithFormat:@"---------------------------14737809831466499882746641449"];
[request setValue:postLength forHTTPHeaderField:@"Content-Length"];
NSString *contentType = [NSString stringWithFormat:@"multipart/form-data; boundary=%@",boundary];
[request addValue:contentType forHTTPHeaderField: @"Content-Type"];
NSMutableData *body = [NSMutableData data];
//video
[body appendData:[[NSString stringWithFormat:@"\r\n--%@\r\n",boundary] dataUsingEncoding:NSUTF8StringEncoding]];
//[body appendData:[@"Content-Disposition: form-data; name=\"uploadedfile\"; filename=\"video.mp4\"\r\n" dataUsingEncoding:NSUTF8StringEncoding]];
//Video Name with Date-Time
NSDateFormatter *dateFormat=[[NSDateFormatter alloc]init];
[dateFormat setDateFormat:@"yyyy-MM-dd-hh:mm:ssa"];
NSString *currDate = [dateFormat stringFromDate:[NSDate date]];
NSString *str = [NSString stringWithFormat:@"Content-Disposition: form-data; name=\"file\"; filename=\"video-%@.mov\"\r\n", currDate];
NSLog(@"String name:: %@",str);
[body appendData:[[NSString stringWithString:str] dataUsingEncoding:NSUTF8StringEncoding]];
//[body appendData:[[NSString stringWithFormat:@"Content-Disposition: form-data; name=\"uploadedfile\"; filename=\"video.mp4\"\r\n"] dataUsingEncoding:NSUTF8StringEncoding]];
//[body appendData:[[NSString stringWithString:@"Content-Type: application/octet-stream\r\n\r\n"] dataUsingEncoding:NSUTF8StringEncoding]];
[body appendData:[[NSString stringWithFormat:@"Content-Type: application/octet-stream\r\n\r\n"] dataUsingEncoding:NSUTF8StringEncoding]];
[body appendData:[NSData dataWithData:videoData1]];
//[body appendData:videoData];
[body appendData:[[NSString stringWithFormat:@"\r\n--%@--\r\n",boundary] dataUsingEncoding:NSUTF8StringEncoding]];
//set the body to the request
[request setHTTPBody:body];
// send the request
NSError *error13;
NSData *returnData = [NSURLConnection sendSynchronousRequest:request returningResponse:nil error:&error13];
if(error13 != nil)
{
NSLog(@"erro is = %@",error13);
}
NSLog(@"return data %@",returnData);
NSString *returnString = [[NSString alloc] initWithData:returnData encoding:NSUTF8StringEncoding];
NSLog(@"response from server is= %@",returnString);

我有几年前在Objective-C中编写的课程，用于生成文件上传请求。
首先，您创建了一个数据类，并加载了您为请求使用的参数。头文件如下所示：
#import <Foundation/Foundation.h>
@interface SDAPIRequestData : NSObject
// the url string you're calling to upload your file data to
@property (nonatomic, strong) NSString *urlString;
// the name of the file you're putting into the body
@property (nonatomic, strong) NSString *filename;
// the data you're trying to upload
@property (nonatomic, strong) NSData *filedata;
@end
生成请求的类如下所示:(首先是头文件）
#import <Foundation/Foundation.h>
#import "SDAPIRequestData.h"
@interface SDAPIFileRequestSetup : NSObject
// init the class and pass the object containing the file data you just created
-(id) initWithRequestData:(SDAPIRequestData *)requestData;
// take the data generated and convert to a request to send via NSURLConnection or NSURLSession
-(NSURLRequest*) toRequest;
@end
现在执行繁重的实现文件：
#import "SDAPIFileRequestSetup.h"
@interface SDAPIFileRequestSetup()
@property (nonatomic, strong) NSString *urlString;
@property (nonatomic, strong) NSString *contentType;
@property (nonatomic, strong) NSString *httpMethod;
@property (nonatomic, strong) NSData *fileData;
@property (nonatomic, strong) NSString *boundary;
@property (nonatomic, strong) NSString *fileType;
@property (nonatomic, strong) NSString *filename;
@property (nonatomic, strong) NSMutableData *body;
@end
@implementation SDAPIFileRequestSetup
@synthesize boundary = _boundary,
fileType = _fileType,
filename = _filename,
contentType = _contentType
;
-(id) initWithRequestData:(SDAPIRequestData *)requestData
{
if (self = [super init])
{
// setup instance properties with request parameters and default values
self.urlString = requestData.urlString;
self.filename = requestData.filename;
self.httpMethod = @"POST";
self.boundary = @"-----------------------------7771935987712374---------------------";
self.contentType = [NSString stringWithFormat:@"multipart/form-data boundary=%@",self.boundary];
self.fileData = requestData.filedata;
// load any post parameters we want to include with the file data in the request
[self setupPostParameters];
// now add the file data to the request data
[self setupFileParameters];
}
return self;
}
// this is called after instantiation to generate a request to be sent to the api
-(NSURLRequest*) toRequest
{
// create the request
NSMutableURLRequest *request = [[NSMutableURLRequest alloc] initWithURL:self.url cachePolicy:NSURLRequestReloadIgnoringLocalAndRemoteCacheData timeoutInterval:30];
// set any custom headers you need set
// set the request method
[request setHTTPMethod: self.httpMethod];
// setup our content type header
[request setValue: self.contentType forHTTPHeaderField: @"Content-Type"];
// set the header for our post data length
[request setValue: self.contentLength forHTTPHeaderField: @"Content-Length"];
// set the post data
[request setHTTPBody: self.body];
return request;
}
// step 1
-(void) setupPostParameters
{
// generate post parameters
NSDictionary *params = @{
// ADD ANY OTHER POST PARAMETERS YOUR API NEEDS HERE
@"type" : self.fileType,
};
// setup post variables
[params enumerateKeysAndObjectsUsingBlock:^(id key, id obj, BOOL *stop)
{
[self.body appendData:[[NSString stringWithFormat:@"--%@\r\n", self.boundary] dataUsingEncoding:NSUTF8StringEncoding]];
[self.body appendData:[[NSString stringWithFormat:@"Content-Disposition: form-data; name=\"%@\"\r\n\r\n", key] dataUsingEncoding:NSUTF8StringEncoding]];
[self.body appendData:[[NSString stringWithFormat:@"%@\r\n", obj] dataUsingEncoding:NSUTF8StringEncoding]];
}];
}
-(void) setupFileParameters
{
// setup file parameters
if (self.fileData)
{
[self.body appendData:[[NSString stringWithFormat:@"--%@\r\n", self.boundary] dataUsingEncoding:NSUTF8StringEncoding]];
[self.body appendData:[[NSString stringWithFormat:@"Content-Disposition: form-data; name=\"file\"; filename=\"%@\"\r\n", self.filename] dataUsingEncoding:NSUTF8StringEncoding]];
[self.body appendData:[[NSString stringWithFormat:@"Content-Type: %@\r\n\r\n", self.fileType] dataUsingEncoding:NSUTF8StringEncoding]];
[self.body appendData:self.fileData];
[self.body appendData:[[NSString stringWithFormat:@"\r\n"] dataUsingEncoding:NSUTF8StringEncoding]];
}
// set the http body
[self.body appendData:[[NSString stringWithFormat:@"--%@--\r\n", self.boundary] dataUsingEncoding:NSUTF8StringEncoding]];
}
-(NSURL*) url
{
return [NSURL URLWithString:self.urlString];
}
-(NSString*)contentLength
{
return [NSString stringWithFormat:@"%lu",(unsigned long)[self.body length]];
}
-(void)setFilename:(NSString *)filename
{
_filename = filename;
// get the file extension
NSString *fileExt = [[filename pathExtension] lowercaseString];
// get our extension map
NSDictionary *extMap = [self filetypeToExtensionMap];
// retrieve the file type or default to png
NSString *newType = extMap[fileExt] ? extMap[fileExt] : @"image/png";
// set the filetype to go with the file extension
[self setFileType:newType];
}
-(NSString*)filename
{
return _filename;
}
-(NSDictionary*)filetypeToExtensionMap
{
return @{@"png" : @"image/png",
@"jpg" : @"image/jpg",
@"jpeg" : @"image/jpeg",
@"avi" : @"video/avi",
@"mpeg" : @"video/mpeg",
@"mpg" : @"video/mpg",
@"mov" : @"video/mov",
@"3gp" : @"video/3gp",
@"wmv" : @"video/wmv",
@"mp4" : @"video/mp4",
@"mpv" : @"video/mpv"
};
}
-(NSMutableData*) body
{
if (! _body)
{
_body = [NSMutableData data];
}
return _body;
}

使用创建SDApiRequestData实例并填充属性。然后创建SDApiFileRequestSetup的实例并传递刚刚创建的数据实例。实例化后，请调用“请求”。使用NSURLSession或NSURLConnection生成传递给服务器的请求的方法。
