Php 在iOS/Objective-C上通过一个请求向服务器发送字符串和图像、音频、视频

我想发送信息以及多媒体文件，如果发现。所有文件都保存在NSString和NSData中，只需一个HTTP请求。信息和多媒体文件未成功附加到正文中。我可以成功地发送信息，但不能在一个HTTP请求中发送多媒体文件

iOS文件 PHP文件

我使用AFN网络，这是有效的

AFHTTPRequestOperationManager *manager = [AFHTTPRequestOperationManager manager];

NSDictionary *parameters = @{@"value1": @"value1",
                             @"value2": @"value2",
                             @"value3": @"value1",
                             };
// BASIC AUTH (if you need):
manager.securityPolicy.allowInvalidCertificates = YES;
manager.requestSerializer = [AFHTTPRequestSerializer serializer];
//[manager.requestSerializer setAuthorizationHeaderFieldWithUsername:@"foo" password:@"bar"];
// BASIC AUTH END

NSString *URLString = @"php file";

/// !!! only jpg, have to cover png as well
manager.requestSerializer = [AFHTTPRequestSerializer serializer];
manager.responseSerializer = [AFHTTPResponseSerializer serializer];

manager.responseSerializer.acceptableContentTypes = [NSSet setWithObject:@"text/html"];
[manager POST:URLString parameters:parameters constructingBodyWithBlock:^(id<AFMultipartFormData> formData) {


    if (image) {
        [formData appendPartWithFileData:image name:@"image" fileName:[NSString stringWithFormat:@"%@.jpg",dateString] mimeType:@"image/jpeg"];
        NSLog(@"image: %@",image);
    }

    if (video) {
        [formData appendPartWithFileData:video name:@"video" fileName:[NSString stringWithFormat:@"%@.mp4",dateString] mimeType:@"video/quicktime"];
        NSLog(@"video: %@",video);
    }

    if (audio) {
        [formData appendPartWithFileData:audio name:@"audio" fileName:[NSString stringWithFormat:@"%@.mp3",dateString] mimeType:@"audio/m4a"];
        NSLog(@"audio: %@",audio);
    }
} success:^(AFHTTPRequestOperation *operation, id responseObject) {
    NSLog(@"Success %@", responseObject);
} failure:^(AFHTTPRequestOperation *operation, NSError *error) {
    UIAlertView *alert=[[UIAlertView alloc]initWithTitle:@"Failure" message:@"Sending Failure" delegate:self cancelButtonTitle:@"OK" otherButtonTitles:nil, nil];
    [alert show];
    NSLog(@"Failure %@, %@", error, operation.responseString);
}];

[self dismissViewControllerAnimated:NO completion:nil];

希望这能起作用

客户端代码在哪里？我用它上传，但它不起作用。发布的PHP代码无效：有19{和20}。

//My PHP file is like this:
<?php

        // Check for proper request
        if (isset($_POST['value1'])) {
            $value1 = $_POST['value1'];
            $value2 = $_POST['value2'];
            $value3 = $_POST['value3'];

            // Insert data into the info table

            $query = "INSERT INTO `info` (`value1`, `value2`, `value3) VALUES ('$value1', '$value2', '$value3')";
            $result = mysql_query($query);
            if ($result) {
                echo "Successfully sent your data!\n";

                $target_path = "multimedia/";
