如何将视频上传到目标C中的服务器ios

Question

我已经尝试了很多方法。没有什么有助于上传。一些代码通过在模拟器中工作将视频上传到服务器。但不能通过设备上传视频到服务器上。请帮我一起工作的意见

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);

我有一个类我几年前写在Objective-C，用于生成文件上传请求。

首先有一个数据类，您可以创建并加载用于请求的参数。头文件看起来是这样的：

#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 

产生该请求的类看起来是这样的：（第一头文件）

#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 

现在的执行文件，做繁重：

#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; 
} 

@end 

使用创建您的SDApiRequestData实例并填充属性。然后创建一个SDApiFileRequestSetup的实例并传递刚刚创建的数据实例。实例化后，调用'toRequest'方法来生成使用NSURLSession或NSURLConnection传递给服务器的请求。
