从iOS上传图像到PHP服务器 [英] Upload image to the PHP server from iOS

问题描述

我知道这个问题也早先被问过，但我的问题有点不同。

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

我想将图像上传到PHP服务器，我想要从iOS发送更多参数和图像。
我在谷歌上搜索并找到了两个解决方案：

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:

1. 我们要么发送图片 Base64 JSON 中的编码字符串。推荐链接。

1. Either we will send an image as Base64 encoded string in JSON. Referred link.

或者我们将使用表单数据将图像上传到服务器。我已经推荐了这个链接。如果有人这样引用我，那么请帮我在这个API中添加更多参数。

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.

现在我的问题是，哪一个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）。

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.

提前致谢。

推荐答案

您可以将图像从iOS App上传到 PHP服务器喜欢这两种方式：

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

使用新的AFNetworking ：

Using New 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];

     }];

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];
    }

这种方式适用于将图像从app上传到php服务器希望这会有所帮助对你而言。

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