我应该对POST数据进行URL编码吗？ [英] Should I URL-encode POST data?

问题描述

我正在将数据发布到外部API（使用PHP，如果它是相关的）。

I'm POSTing data to an external API (using PHP, if it's relevant).

我应该对我传递的POST变量进行URL编码吗？

Should I URL-encode the POST variables that I pass?

或者我只需要URL-编码GET数据？

Or do I only need to URL-encode GET data?

谢谢！

更新：这是我的PHP，如果相关：

UPDATE: This is my PHP, in case it is relevant:

$fields = array(
    'mediaupload'=>$file_field,
    'username'=>urlencode($_POST["username"]),
    'password'=>urlencode($_POST["password"]),
    'latitude'=>urlencode($_POST["latitude"]),
    'longitude'=>urlencode($_POST["longitude"]),
    'datetime'=>urlencode($_POST["datetime"]),
    'category'=>urlencode($_POST["category"]),
    'metacategory'=>urlencode($_POST["metacategory"]),
    'caption'=>($_POST["description"])
);
$fields_string = http_build_query($fields);
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL,$url);
curl_setopt($ch,CURLOPT_POST,count($fields));
curl_setopt($ch,CURLOPT_POSTFIELDS,$fields);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
$response = curl_exec($ch);

推荐答案

一般答案

您问题的一般答案取决于它。您可以通过指定HTTP标头中的Content-Type来决定。

General Answer

The general answer to your question is that it depends. And you get to decide by specifying what your "Content-Type" is in the HTTP headers.

值application / x-www-form-urlencoded表示你的POST主体需要像GET参数字符串一样进行URL编码。值multipart / form-data表示您将使用内容分隔符而不是url编码内容。

A value of "application/x-www-form-urlencoded" means that your POST body will need to be URL encoded just like a GET parameter string. A value of "multipart/form-data" means that you'll be using content delimiters and NOT url encoding the content.

对于您正在使用的PHP库（CURL）的特定答案，您应该阅读此处的文档。

For an answer specific to the PHP libraries you're using (CURL), you should read the documentation here.

这里是相关信息：

CURLOPT_POST

TRUE做一个常规的HTTP POST。
此POST是普通的application / x-www-form-urlencoded类型，最常用于HTML表单。

TRUE to do a regular HTTP POST. This POST is the normal application/x-www-form-urlencoded kind, most commonly used by HTML forms.

CURLOPT_POSTFIELDS

在HTTPPOST操作中发布的完整数据。要发布文件，请在文件前加上@并使用完整路径。可以通过使用格式为'; type = mimetype'的类型的文件名来明确指定文件类型。此参数可以作为urlencoded字符串传递，如'para1 = val1& para2 = val2& ...'，或者作为一个数组，字段名称为键，字段数据为值。如果value是数组，则Content-Type标头将设置为multipart / form-data。从PHP 5.2.0开始，如果使用@前缀将文件传递给此选项，则value必须是数组。

The full data to post in a HTTP "POST" operation. To post a file, prepend a filename with @ and use the full path. The filetype can be explicitly specified by following the filename with the type in the format ';type=mimetype'. This parameter can either be passed as a urlencoded string like 'para1=val1&para2=val2&...' or as an array with the field name as key and field data as value. If value is an array, the Content-Type header will be set to multipart/form-data. As of PHP 5.2.0, value must be an array if files are passed to this option with the @ prefix.
