iOS将图像和数据发布到PHP mySQL数据库

我试图张贴多个图片连同文本数据到我的PHP页面，然后到mySQL数据库，但我得到一个400错误响应，我无法发布任何东西。

我能够只发布数据或只有图片，但不能两个在一起。
看来我没有正确设置POST。

我需要张贴很多图片，但是现在只是想要一个滚动 。

任何帮助将不胜感激！

NSData *imageData = UIImageJPEGRepresentation(_image1.image, 10); //Add boundary NSMutableString *boundary = [NSMutableString stringWithString:@"----Boundary+"]; //Append 5 random chars to the end of the boundary for(int i = 0; i < 5; i++){ BOOL lowercase = arc4random() % 2; if(lowercase){ [boundary appendFormat:@"%c", (arc4random() % 26) + 97]; } else { [boundary appendFormat:@"%c", (arc4random() % 26) + 65]; } //Commit to mySQL Database NSString *post = [NSString stringWithFormat:@"title=%@&price=%@&description=%@&latitude=%@&longitude=%@&location=%@&category_id=%@",sellTitle, sellPrice, sellDescription, sellLatitude, sellLongitude, sellLocation, sellCategory]; NSLog(@"PostData: %@",post); NSURL *url=[NSURL URLWithString:@"http://myURL/testphp.php"]; NSData *postData = [post dataUsingEncoding:NSASCIIStringEncoding]; NSString *postLength = [NSString stringWithFormat:@"%d", [postData length]]; NSMutableURLRequest *request = [[NSMutableURLRequest alloc] init]; [request setURL:url]; [request setHTTPMethod:@"POST"]; [request setValue:postLength forHTTPHeaderField:@"Content-Length"]; [request setValue:@"application/x-www-form-urlencoded" forHTTPHeaderField:@"Content-Type"]; [request setHTTPBody:postData]; //PICTURE STUFF 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; name=\"image\"; filename=\"picture.png\"\r\n"] 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]; NSError *error = [[NSError alloc] init]; NSHTTPURLResponse *response = nil; NSData *urlData=[NSURLConnection sendSynchronousRequest:request returningResponse:&response error:&error]; NSLog(@"Response code:%d", [response statusCode]); if ([response statusCode] >=200 && [response statusCode] <300) { NSString *responseData = [[NSString alloc] initWithData:urlData encoding:NSUTF8StringEncoding]; NSLog(@"Respinse ==> %@", responseData); //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); NSLog(@"%@",boundary); NSLog(@"Title Saved: %@", sellTitle);

这是我设法为此工作的代码。 这是完美的工作。

  //begin new method NSString *urlString = @"http://www.yourURLforPostingData.com"; NSMutableURLRequest *request = [[NSMutableURLRequest alloc] init]; [request setURL:[NSURL URLWithString:urlString]]; [request setHTTPMethod:@"POST"]; NSMutableData *body = [NSMutableData data]; NSString *boundary = @"---------------------------14737809831466499882746641449"; NSString *contentType = [NSString stringWithFormat:@"multipart/form-data; boundary=%@", boundary]; [request addValue:contentType forHTTPHeaderField:@"Content-Type"]; // picture NSData *imageData = UIImageJPEGRepresentation(_image1.image, .25); [body appendData:[[NSString stringWithFormat:@"\r\n--%@\r\n",boundary] dataUsingEncoding:NSUTF8StringEncoding]]; [body appendData:[[NSString stringWithFormat:@"Content-Disposition: form-data; name=\"image\"; filename=\"picture.png\"\r\n"] 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]]; // Description Text NSString *description = [defaults objectForKey:@"description"]; [body appendData:[[NSString stringWithFormat:@"--%@\r\n", boundary] dataUsingEncoding:NSUTF8StringEncoding]]; [body appendData:[[NSString stringWithFormat:@"Content-Disposition: form-data; name=\"description\"\r\n\r\n"] dataUsingEncoding:NSUTF8StringEncoding]]; [body appendData:[[NSString stringWithString:description] dataUsingEncoding:NSUTF8StringEncoding]]; [body appendData:[@"\r\n" dataUsingEncoding:NSUTF8StringEncoding]]; // Title Text NSString *title = [defaults objectForKey:@"sellTitle"]; [body appendData:[[NSString stringWithFormat:@"--%@\r\n", boundary] dataUsingEncoding:NSUTF8StringEncoding]]; [body appendData:[[NSString stringWithFormat:@"Content-Disposition: form-data; name=\"title\"\r\n\r\n"] dataUsingEncoding:NSUTF8StringEncoding]]; [body appendData:[[NSString stringWithString:title] dataUsingEncoding:NSUTF8StringEncoding]]; [body appendData:[@"\r\n" dataUsingEncoding:NSUTF8StringEncoding]]; // close form [body appendData:[[NSString stringWithFormat:@"--%@--\r\n", boundary] dataUsingEncoding:NSUTF8StringEncoding]]; // set request body [request setHTTPBody:body]; //return and test NSData *returnData = [NSURLConnection sendSynchronousRequest:request returningResponse:nil error:nil]; NSString *returnString = [[NSString alloc] initWithData:returnData encoding:NSUTF8StringEncoding]; NSLog(@"%@", returnString); //END NEW METHOD
