ios 从iOS上传图片到PHP服务器

Upload image to the PHP server from iOS

提问by Vinay Jain

I know this question has been asked earlier as well but my issue is a bit different.

我知道之前也有人问过这个问题，但我的问题有点不同。

I want to upload an image to the PHP server and i want to send more parameters along with an image from an iOS. I searched on the google and found two solutions:

我想将图像上传到 PHP 服务器，并且我想从 iOS 发送更多参数以及图像。我在谷歌上搜索，找到了两个解决方案：

1. Either we will send an image as Base64encoded string in JSON. Referred link.

2. Or we will upload an image to server using form data. I have referred this link. If someone refers me this way, then please help me to add more parameters in this API.

1. 要么我们将图像作为Base64编码字符串发送到JSON. 参考链接。

2. 或者我们将使用表单数据将图像上传到服务器。我已经提到了这个链接。如果有人以这种方式引用我，那么请帮助我在此 API 中添加更多参数。

Now my question is, which one is the best way to upload an image to the server and i have to send more parameters (username, password and more details) in the same web service call.

现在我的问题是，哪一种是将图像上传到服务器的最佳方式，我必须在同一个 Web 服务调用中发送更多参数（用户名、密码和更多详细信息）。

Thanks in advance.

提前致谢。

You can upload image from iOS App to PHP serverlike this two way:

您可以通过PHP server以下两种方式从 iOS 应用上传图像：

Using New AFNetworking:

使用新的 AFNetworking：

#import "AFHTTPRequestOperation.h"
#import "AFHTTPRequestOperationManager.h"

    NSString *stringUrl =@"http://www.myserverurl.com/file/uloaddetails.php?"
    NSString *string =@"http://myimageurkstrn.com/img/myimage.png"       
    NSURL *filePath = [NSURL fileURLWithPath:string];

   NSDictionary *parameters  = [NSDictionary dictionaryWithObjectsAndKeys:userid,@"id",String_FullName,@"fname",String_Email,@"emailid",String_City,@"city",String_Country,@"country",String_City,@"state",String_TextView,@"bio", nil];

    AFHTTPRequestOperationManager *manager = [AFHTTPRequestOperationManager manager];

    [manager POST:stringUrl parameters:parameters constructingBodyWithBlock:^(id<AFMultipartFormData> formData)
     {
         [formData appendPartWithFileURL:filePath name:@"userfile" error:nil];//here userfile is a paramiter for your image 
     }
     success:^(AFHTTPRequestOperation *operation, id responseObject)
     {
         NSLog(@"%@",[responseObject valueForKey:@"Root"]);
         Alert_Success_fail = [[UIAlertView alloc] initWithTitle:@"myappname" message:string delegate:self cancelButtonTitle:@"ok" otherButtonTitles:nil, nil];
         [Alert_Success_fail show];     

     }
     failure:^(AFHTTPRequestOperation *operation, NSError *error)
     {
         Alert_Success_fail = [[UIAlertView alloc] initWithTitle:@"myappname" message:[error localizedDescription] delegate:self cancelButtonTitle:@"ok" otherButtonTitles:nil, nil];
         [Alert_Success_fail show];

     }];

Second use NSURLConnection:

第二次使用 NSURLConnection：

-(void)uploadImage
    {       
        NSData *imageData = UIImagePNGRepresentation(yourImage);

        NSString *urlString = [ NSString stringWithFormat:@"http://yourUploadImageURl.php?intid=%@",1];

        NSMutableURLRequest *request = [[[NSMutableURLRequest alloc] init] autorelease];
        [request setURL:[NSURL URLWithString:urlString]];
        [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 stringWithString:[NSString stringWithFormat:@"Content-Disposition: form-data; name=\"userfile\"; filename=\"%@\"\r\n", 1]] 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];

        [NSURLConnection sendSynchronousRequest:request returningResponse:nil error:nil];
    }

This both way working fine for uploading image from app to php server hope this helps for you.

这两种方式都可以很好地将图像从应用程序上传到 php 服务器，希望这对您有所帮助。

Using AFNetworkingthis is how I do it:

使用AFNetworking这就是我的做法：

NSMutableDictionary *params = [[NSMutableDictionary alloc]init];
    [params setObject:@"myUserName" forKey:@"username"];
    [params setObject:@"1234" forKey:@"password"];
    [[AFHTTPRequestOperationLogger sharedLogger] startLogging];
    NSData *imageData;
    NSString *urlStr = [NSString stringWithFormat:@"http://www.url.com"];
    NSURL *url = [NSURL URLWithString:urlStr];

    AFHTTPClient *httpClient = [[AFHTTPClient alloc] initWithBaseURL:url];
       imageData = UIImageJPEGRepresentation(mediaFile, 0.5);


    NSMutableURLRequest *request = [httpClient multipartFormRequestWithMethod:@"POST" path:nil parameters:params constructingBodyWithBlock: ^(id <AFMultipartFormData>formData)
    {
              [formData appendPartWithFileData:imageData name:@"mediaFile" fileName:@"picture.png" mimeType:@"image/png"];
    }];

    AFJSONRequestOperation *operation = [AFJSONRequestOperation JSONRequestOperationWithRequest:request

    success:^(NSURLRequest *request, NSHTTPURLResponse *response, id JSON)
    {

        UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"File was uploaded" message:@""
                                                       delegate:self cancelButtonTitle:@"Close" otherButtonTitles: nil];
        [alert show];
    }
    failure:^(NSURLRequest *request , NSURLResponse *response , NSError *error , id JSON)
    {
        NSLog(@"request: %@",request);
        NSLog(@"Failed: %@",[error localizedDescription]);
    }];


    [operation setUploadProgressBlock:^(NSUInteger bytesWritten, long long totalBytesWritten, long long totalBytesExpectedToWrite)
    {
        NSLog(@"Sent %lld of %lld bytes", totalBytesWritten, totalBytesExpectedToWrite);
    }];
    [httpClient enqueueHTTPRequestOperation:operation];

Try this this is work for me.
