iPhone carica file multipart utilizzando AFNetworking

Question

Nella mia app iOS voglio caricare il file con l'API java usando NSMutableURLRequest per file multipart. ecco la forma che mostra il parametro.

<form action="API_URL" encType='multipart/form-data' method=post> 
      <input type=file name="files"> 
      <input type=submit value="Upload Attempt Files"> 

EDIT form2

 <form action='URL' method="post" encType='multipart/form-data'> 
<input name="key1" value='123'> 
<input name="key2" value='asdf'> 
<input name="key3" value='qwerty'> 
<input name="key4" value='aaa'> 
<input name="key5" value='aaa'> 
<input name="key6" value='false'> 
<input type="file" name="files"> 
<input type=submit value="Create Forum Posts"> 
    </form>   

Come posso raggiungere questo obiettivo.

qui questo Question mostra come caricare file multipart utilizzando AFNetworking in iOS (obiettivo c). Ma non sto ottenendo come inserire parametri come da modulo che sto usando.

prega di aiutare e suggerire

Answer 1

Guardando il tuo HTML, il name del vostro <input type=file> è files, e, quindi, è necessario utilizzare @"files" come parametro al metodo nameappendPartWithFileData. Ad esempio, con AFNetworking 3.x:

AFHTTPSessionManager *manager = [AFHTTPSessionManager manager]; 

[manager POST:urlString parameters:nil constructingBodyWithBlock:^(id<AFMultipartFormData> formData) { 
    [formData appendPartWithFileData:imageData 
           name:@"files" 
          fileName:photoName mimeType:@"image/jpeg"]; 

    [formData appendPartWithFormData:[key1 dataUsingEncoding:NSUTF8StringEncoding] 
           name:@"key1"]; 

    [formData appendPartWithFormData:[key2 dataUsingEncoding:NSUTF8StringEncoding] 
           name:@"key2"]; 

    // etc. 
} progress:nil success:^(NSURLSessionDataTask *task, id responseObject) { 
    NSLog(@"Response: %@", responseObject); 
} failure:^(NSURLSessionDataTask *task, NSError *error) { 
    NSLog(@"Error: %@", error); 
}];

-(void) makePhotoUploadRequest{ 

    NSArray *keys = [[NSArray alloc]initWithObjects:@"UserID", @"CompanyName" ,@"Location",@"Latitude",@"Longitude",@"Tagline",@"Goals",@"ColorName",nil]; 
    NSArray *values =[[NSArray alloc]initWithObjects:@"103",@"queppelin",@"Jaiur",@"11.3" ,@"12.3",@"Let's do it",@"Let's do it",@"Let's do it", nil]; 
    NSMutableURLRequest *request = [[NSMutableURLRequest alloc] init]; 

    NSURL *baseUrl = [NSURL URLWithString:[NSString stringWithFormat:@"%@%@/%@/RegisterCompanyUser",serverRequest,serverPort,serverName]]; 

    NSString *charset = (NSString *)CFStringConvertEncodingToIANACharSetName(CFStringConvertNSStringEncodingToEncoding(NSUTF8StringEncoding)); 
    [request setURL:baseUrl]; 
    [request setHTTPMethod:@"POST"]; 

    NSString *boundary = @"0xKhTmLbOuNdArY"; 
    NSString *endBoundary = [NSString stringWithFormat:@"\r\n--%@\r\n", boundary]; 

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

    NSMutableData *tempPostData = [NSMutableData data]; 
    [tempPostData appendData:[[NSString stringWithFormat:@"--%@\r\n", boundary] dataUsingEncoding:NSUTF8StringEncoding]]; 


      for(int i=0;i<keys.count;i++){ 
       NSString *str = values[i]; 
       NSString *key =keys[i]; 
       NSLog(@"Key Value pair: %@-%@",key,str); 
       [tempPostData appendData:[[NSString stringWithFormat:@"Content-Disposition: form-data; name=\"%@\"\r\n\r\n", key] dataUsingEncoding:NSUTF8StringEncoding]]; 
       [tempPostData appendData:[str dataUsingEncoding:NSUTF8StringEncoding]]; 
       // [tempPostData appendData:[@"\r\n--%@\r\n",boundary dataUsingEncoding:NSUTF8StringEncoding]]; 
        [tempPostData appendData:[endBoundary dataUsingEncoding:NSUTF8StringEncoding]]; 

     } 





    // Sample file to send as data 
    [tempPostData appendData:[[NSString stringWithFormat:@"Content-Disposition: form-data; name=\"Image\"; filename=\"%@\"\r\n", @"company-logo.png"] dataUsingEncoding:NSUTF8StringEncoding]]; 
    [tempPostData appendData:[[NSString stringWithString:@"Content-Type: application/octet-stream\r\n\r\n"] dataUsingEncoding:NSUTF8StringEncoding]]; 

    UIImage *myImageObj = [UIImage imageNamed:@"company-logo.png"]; 
    NSData *mydata= UIImagePNGRepresentation(myImageObj); 
    NSLog(@"Image data:%d",mydata.length); 
     [tempPostData appendData:mydata]; 

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

    NSURLConnection *theConnection = [[NSURLConnection alloc] initWithRequest:request delegate:self]; 
    if(theConnection) 
    { 
     dataWebService = [NSMutableData data] ; 
     NSLog(@"request uploading successful"); 
    } 
    else 
    { 
     NSLog(@"theConnection is NULL"); 
    } 


}
