iphone - 从 iphone 同步(上传)远程服务器上的多个数据

Question

我正在尝试从 iPhone 同步或上传远程服务器上的数据，但没有成功。我从 1 周开始尝试，但没有成功。
如何解决这个问题。我正在使用 NSURLConnection 方法或任何提供想法的方法ASIHTTPRequest 方法 但我是 ASIHTTPRequest 的新手。我只需要这个方法用于这个代码:

- (void)sendRequestforContent
{   
    //this for finding the date of sync on the server
    NSDate* date = [NSDate date];
    //Create the dateformatter object
    NSDateFormatter* formatter = [[[NSDateFormatter alloc] init] autorelease];
    //Set the required date format
    [formatter setDateFormat:@"dd-MMM-yyyy"];
    //Get the string date
    NSString* str = [formatter stringFromDate:date];

    NSError *error = nil; 

    NSHTTPURLResponse *response = nil; 
    NSMutableData *postBody = [NSMutableData data];
    NSURL *url = [NSURL URLWithString:@"http://www.google.com"]; 

    NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:url]; 

    NSString *boundary = @"-------------------a9d8vyb89089dy70"; 

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

    [request setHTTPMethod:@"POST"]; 

    [request setValue:contentType forHTTPHeaderField:@"Content-Type"];

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

    //this is for TOKEN_API
    [postBody appendData:[@"Content-disposition: form-data; name=\"Token\"\r\n\r\n" dataUsingEncoding:NSUTF8StringEncoding]]; 

    [postBody appendData:[tokenapi dataUsingEncoding:NSUTF8StringEncoding]]; 

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

    //this for the CONTENT_ID
    [postBody appendData:[@"Content-disposition: form-data; name=\"contentID\"\r\n\r\n" dataUsingEncoding:NSUTF8StringEncoding]]; 

    [postBody appendData:[content_id dataUsingEncoding:NSUTF8StringEncoding]]; 

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

    //this for the CONTENTTYPE_ID
    [postBody appendData:[@"Content-disposition: form-data; name=\"contentTypeID\"\r\n\r\n" dataUsingEncoding:NSUTF8StringEncoding]]; 
    NSString *ContentTypeString = [NSString stringWithFormat:@"%d",content_type];
    [postBody appendData:[ContentTypeString dataUsingEncoding:NSUTF8StringEncoding]]; 

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


    //this for the CONTENT_Location_Id
    [postBody appendData:[@"Content-disposition: form-data; name=\"contentLocationID\"\r\n\r\n" dataUsingEncoding:NSUTF8StringEncoding]]; 

    [postBody appendData:[contenLocation_id dataUsingEncoding:NSUTF8StringEncoding]]; 

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


    //this is for the User_Caption
    [postBody appendData:[@"Content-disposition: form-data; name=\"userCaption\"\r\n\r\n" dataUsingEncoding:NSUTF8StringEncoding]]; 

    [postBody appendData:[user_caption dataUsingEncoding:NSUTF8StringEncoding]]; 

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


    //this is for the User_Comment
    [postBody appendData:[@"Content-disposition: form-data; name=\"userComment\"\r\n\r\n" dataUsingEncoding:NSUTF8StringEncoding]]; 

    [postBody appendData:[user_comment dataUsingEncoding:NSUTF8StringEncoding]]; 

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



    //this for the Tags
    [postBody appendData:[@"Content-disposition: form-data; name=\"tags\"\r\n\r\n" dataUsingEncoding:NSUTF8StringEncoding]]; 

    [postBody appendData:[tag dataUsingEncoding:NSUTF8StringEncoding]]; 

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


    //this for the Date_Record
    [postBody appendData:[@"Content-disposition: form-data; name=\"dateRecorded\"\r\n\r\n" dataUsingEncoding:NSUTF8StringEncoding]]; 

    [postBody appendData:[date_recorded dataUsingEncoding:NSUTF8StringEncoding]]; 

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

    //this for the image_data
    [postBody appendData:[[NSString stringWithFormat:@"Content-disposition: form-data; name=\"image_file\"; filename=\"%@\"\r\n",@"image.jpg"] dataUsingEncoding:NSUTF8StringEncoding]];

    [postBody appendData:[@"Content-Type: image/jpg\r\n\r\n" dataUsingEncoding:NSUTF8StringEncoding]];

    [postBody appendData:image];

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



    //this for the Share_type
    [postBody appendData:[@"Content-disposition: form-data; name=\"shareType\"\r\n\r\n" dataUsingEncoding:NSUTF8StringEncoding]]; 
    NSString *ShareString = [NSString stringWithFormat:@"%d",share_type];
    [postBody appendData:[ShareString dataUsingEncoding:NSUTF8StringEncoding]]; 

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

    //this for the Views
    [postBody appendData:[@"Content-disposition: form-data; name=\"views\"\r\n\r\n" dataUsingEncoding:NSUTF8StringEncoding]]; 
     NSString *ViewsString = [NSString stringWithFormat:@"%d",views];
    [postBody appendData:[ViewsString dataUsingEncoding:NSUTF8StringEncoding]]; 

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


    //this for the PLAY_time
    [postBody appendData:[@"Content-disposition: form-data; name=\"playTime\"\r\n\r\n" dataUsingEncoding:NSUTF8StringEncoding]]; 
    NSString *TimeString = [NSString stringWithFormat:@"%d",play_time];
    [postBody appendData:[TimeString dataUsingEncoding:NSUTF8StringEncoding]]; 

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


    //this for the Posted_By
    [postBody appendData:[@"Content-disposition: form-data; name=\"postedBy\"\r\n\r\n" dataUsingEncoding:NSUTF8StringEncoding]]; 
    [postBody appendData:[postred_by dataUsingEncoding:NSUTF8StringEncoding]]; 


    //this for the AVG_Rating
    [postBody appendData:[[NSString stringWithFormat:@"\r\n--%@\r\n", boundary] dataUsingEncoding:NSUTF8StringEncoding]];

    [postBody appendData:[@"Content-disposition: form-data; name=\"avgRating\"\r\n\r\n" dataUsingEncoding:NSUTF8StringEncoding]]; 
    NSString *AvgString = [NSString stringWithFormat:@"%d",avg_rating];
    [postBody appendData:[AvgString dataUsingEncoding:NSUTF8StringEncoding]]; 

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


    [postBody appendData:[@"Content-disposition: form-data; name=\"LastSyncDate\"\r\n\r\n" dataUsingEncoding:NSUTF8StringEncoding]]; 
    [postBody appendData:[str dataUsingEncoding:NSUTF8StringEncoding]]; 

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


    [request setHTTPBody:postBody];

    NSData *shoutData = [NSURLConnection sendSynchronousRequest:request returningResponse:&response error:&error];

    NSString *returnString = [[NSString alloc] initWithData:shoutData encoding:NSUTF8StringEncoding];
    NSLog(@"%@", returnString);
}

它不会进入这个方法

- (void)connectionDidFinishLoading:(NSURLConnection *)connection 
{      
    loginStatus = [[NSString alloc] initWithBytes: [webData mutableBytes] length:[webData length] encoding:NSUTF8StringEncoding]; 
    NSLog(@"%@", loginStatus);  
} 

它在控制台上显示 HTML 页面。

Answer 1

NSString *urlString = [[NSString alloc] initWithString:@"http://192.168.0.1:96/JourneyMapperAPI?RequestType=Content&Command=New"];
NSURL *url = [[NSURL alloc] initWithString:urlString];

NSMutableData *postBody;//Here comes your data that you have created in the question
NSString *msgLength = [[NSString alloc] initWithFormat:@"%d", [postBody length]];//use either [postBody length] or [postBody bytes], I am not sure about it

ASIFormDataRequest *serverRequest = [ASIFormDataRequest requestWithURL:url];
[serverRequest addRequestHeader:@"Content-Type" value:@"text/xml; charset=utf-8"];
[serverRequest addRequestHeader:@"Content-Length" value:msgLength];
[serverRequest appendPostData:postBody];
[serverRequest setDelegate:self];
[serverRequest setDidFinishSelector:@selector(sendAlertsRequestDone:)];
[serverRequest setDidFailSelector:@selector(sendAlertsRequestWentWrong:)];
[serverRequest setUploadProgressDelegate:progressView];// here progressView is UIProgressbar
[serverRequest startAsynchronous];

[urlString release];
[url release];
[postBody release];
[msgLength release];
