POST'ing WebClient中的数组(C#/。NET)数组、POST、ing、NET

2023-09-02 10:52:06 作者:可爱到炸

我有,有一个WebRequest的是一个POST增加了多次相同的密钥,从而使其成为一个数组在PHP,Java小等,我想改写这个来使用Web客户端眼中的.NET应用程序,但如果我叫Web客户端的QueryString.Add()使用相同的密钥多次,它只是附加了新的价值观,使值数组的一个逗号分隔的单个值代替。

I've got a .net application that has a WebRequest that to a POST adds multiple times the same key, thus making it an array in the eyes of PHP, Java Servlets etc. I wanted to rewrite this to using WebClient, but if I call WebClient's QueryString.Add() with the same key multiple times, it just appends the new values, making a comma-separated single value instead of an array of values.

我使用后的WebClient的UploadFile()我的要求,因为除了这些元数据,我想一个文件发布。

I post my request using WebClient's UploadFile() because in addition to these metadata I want a file posted.

我如何使用Web客户端来发布值,而不是单个值的数组(逗号分隔值)?

How can I use WebClient to post an array of values instead of a single value (of comma-separated values)?

推荐答案

PHP只是一个分析器转换以数组格式发送到一个数组多个值。 格式为< arrayName中><键>。

PHP simply uses a parser to convert multiple values sent with array format to an array. The format is <arrayName>[<key>].

所以,如果你想从 $收到PHP数组_ GET 添加这些查询参数: X [键1] X [密钥2] $ _ GET ['X'] 在PHP将是一个包含有2项: [X] =&GT;阵列(2){[键1] =&GT; &LT;凡是&GT; [键2] =&GT; &LT;凡是&GT; }

So if you want to receive an array in PHP from $_GET add these query parameters: x[key1] and x[key2]. $_GET['x'] in PHP will be an array with 2 items: ["x"]=> array(2) { ["key1"]=> <whatever> ["key2"]=> <whatever> }.

修改 - 你可以试试这个扩展方法:

Edit - you can try this extension method:

public static class WebClientExtension
{
    public static void AddArray(this WebClient webClient, string key, params string[] values)
    {
        int index = webClient.QueryString.Count;

        foreach (string value in values)
        {
            webClient.QueryString.Add(key + "[" + index + "]", value);
            index++;
        }
    }
}

在code:

and in code:

webClient.AddArray("x", "1", "2", "3");
webClient.AddArray("x", "4");

或手动:

webClient.QueryString.Add("x[key1]", "4");
webClient.QueryString.Add("x[key2]", "1");

有没有错误检查,等等。你可以自己做:)

There is no error checking, etc. You can do it yourself :)
