上传图像到网络服务器从ios到PHP

Question

我有一个应用程序，我在上传一些数据到Web服务器。

这是我从谷歌的链接中获得的代码。

UIImage * img = [UIImage imageNamed:@"register_btn.png"]; 

    NSData *imageData = UIImageJPEGRepresentation(img, 90); 
    NSString *urlString = @"http://tes.in/testservices/User.php"; 

    NSMutableURLRequest *request = [[NSMutableURLRequest alloc] init]; 
    [request setURL:[NSURL URLWithString:urlString]]; 
    [request setHTTPMethod:@"POST"]; 

    NSString *boundary = @"------------------------1473780983146499882746641449"; 
    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 stringWithFormat:@"Content-Disposition: form-data;filename=\a.jpg\"\r\n"] dataUsingEncoding:NSUTF8StringEncoding]]; 
    [body appendData:[[NSString stringWithFormat:@"Content-Type: application/json\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]; 

    NSData *returnData = [NSURLConnection sendSynchronousRequest:request returningResponse:nil error:nil]; 
    NSString *returnString =[[NSString alloc] initWithData:returnData encoding:NSUTF8StringEncoding]; 
     //profile_photo_link 
    NSLog(@"%@",returnString); 

但我没有得到什么，我需要在代码中传递。

我的照片上传参数是“photo_link”。我已经给出了PHP web服务的链接。

我知道这里有很多问题，但我不知道在哪里传递我的参数以及如何检查请求字符串。

如果可能的话，请任何人都可以给我PHP的代码来解码图像。

请帮帮我。

在此先感谢。

试试这个代码：

-(void)uploadImageOnServer:(NSData *)imageData forId:(NSString *)imageId 
{    
    NSURL *strURL = @"http://webserver.com/....";//give your URL here 

    // setting up the request object now 
    NSMutableURLRequest *request = [[NSMutableURLRequest alloc] init] ; 
    [request setURL:strURL]; 
    [request setHTTPMethod:@"POST"]; 

    NSString *boundary = @"---------------------------147378098314876653456641449"; 
    NSString *contentType = [NSString stringWithFormat:@"multipart/form-data; boundary=%@",boundary]; 
    [request addValue:contentType forHTTPHeaderField: @"Content-Type"]; 

    /* 
    now lets create the body of the post 
    */ 
    NSMutableData *body = [NSMutableData data]; 

    [body appendData:[[NSString stringWithFormat:@"\r\n--%@\r\n",boundary] dataUsingEncoding:NSUTF8StringEncoding]]; 
    NSString *stringData = [NSString stringWithFormat:@"Content-Disposition: form-data; name=\"Documents\"; filename=\%@.jpg\r\n",imageId]; 
    [body appendData: [stringData dataUsingEncoding:NSUTF8StringEncoding]]; 
    [body appendData:[@"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]]; 
    // setting the body of the post to the request 
    [request setHTTPBody:body]; 

    // now lets make the connection to the web 
    NSData *returnData = [NSURLConnection sendSynchronousRequest:request returningResponse:nil error:nil]; 


    NSString *returnString = [[NSString alloc] initWithData:returnData encoding:NSUTF8StringEncoding]; 

    NSLog(@"%@",returnString); 
} 

“文档”是您要的图像保存到后端服务器的文件夹名称。

祝你好运！
