AFNetworking表单请求（在一个请求中上传多个文件） [英] AFNetworking Form Request (Multiple File uploads in One Request)

问题描述

我们正在开发iOS应用程序。该应用程序在一个请求中提供单个和多个文件上载选项。我正在使用AFNetworking进行单个文件上传，并且工作正常。现在，我们需要支持多个文件上传。我有我的html代码实际上是从web上传多个文件。我需要从iOS应用程序做同样的事情。任何人都可以建议我们如何使用AFNetworking做同样的事情？

We are developing an iOS application. The app is providing single as well as multiple file upload options in one single request. I'm using AFNetworking for single file uploads and which works fine. Now, we need to support multiple file upload. I have got the html code with me which actually does the multiple file uploads from the web.I need to do the same from iOS app. Can anybody suggest how do we do the same using AFNetworking?

<form method="post" action="upload.php?key=ac2a04cc7b6d4420fa5e5eb1701fb0cc1acf7916&channelid=1" enctype="multipart/form-data">
<label>Title:</label> <input name="title" value="My Video Title" /><br />
<label>Date:</label> <input name="date" value="<?php echo time(); ?>" /><br />
<label>Location:</label> <input name="location" value="Sydney, Australia" /><br />
<textarea name="description">The description of the photo/video goes here</textarea><br />
<input name="file[]" type="file" multiple="multiple" /><br />

推荐答案

使用下面的代码将多个文件发送到您的表单。如果需要更改任何内容，请根据您的需要进行自定义。

Use below code to send multiple file to your form. Customize as per your need if required to change anything.

  NSArray *imageArray = [NSArray arrayWithObjects:[UIImage imageNamed:@"close_button.png"],[UIImage imageNamed:@"done_button.png"], nil];
    __block int i=1;
    AFHTTPClient *httpClient = [[AFHTTPClient alloc] initWithBaseURL:@"yoururl"];
    NSMutableURLRequest *request=nil;
        request = [httpClient multipartFormRequestWithMethod:@"POST" path:@"yoururl" parameters:nil constructingBodyWithBlock: ^(id <AFMultipartFormData>formData)
        {
            for(UIImage *eachImage in imageArray)
            {
                NSData *imageData = UIImagePNGRepresentation(eachImage);
                [formData appendPartWithFileData:imageData name:[NSString stringWithFormat:@"file%d",i] fileName:[NSString stringWithFormat:@"abc%d.png",i] mimeType:@"image/png"];
                i++;
            }

        }];

    AFHTTPRequestOperation *operation = [[AFHTTPRequestOperation alloc] initWithRequest:request];
    [httpClient registerHTTPOperationClass:[AFHTTPRequestOperation class]];

    [operation setCompletionBlockWithSuccess:^(AFHTTPRequestOperation *operation, id responseObject)
     {
         NSData *data = (NSData *)responseObject;
         NSString *str = [[NSString alloc] initWithData:data encoding:NSUTF8StringEncoding];
         NSLog(@"Response -> %@",str);

     } failure:^(AFHTTPRequestOperation *operation, NSError *error)
     {
         NSLog(@"Error -> %@",[error localizedDescription]);
     }];

在服务器端我已经检查过test.php代码，我刚刚打印了print_r（$ _ FILES）并且在我的情况下打印以后对不起让你猜测。

On server side I have checked with test.php code, I have just printed print_r($_FILES) and it prints following in my case sorry to keep you guessing.

Response -> Array
(
    [file1] => Array
        (
            [name] => abc1.png
            [type] => image/png
            [tmp_name] => /tmp/phpiWbxSn
            [error] => 0
            [size] => 1997
        )

    [file2] => Array
        (
            [name] => abc2.png
            [type] => image/png
            [tmp_name] => /tmp/phpwtWTE8
            [error] => 0
            [size] => 1847
        )
)
