Question

我正在使用我在互联网上找到的修改过的php脚本作为javascript和twitter api 1.1之间的代理（我需要这样做，因为javascript不能执行oauth操作，而api 1.1要求完全相同：认证）。

脚本工作正常 - 直到我搜索主题标签，然后oauth失败。

以下是我在搜索@ z25org

时从twitter获得的curl_info的示例

url: http://api.twitter.com/1.1/search/tweets.json?q=%40z25org
content_type: application/json;charset=utf-8
http_code: 200

正如你所看到的那样（http_code：200）。但是当我搜索主题标签时：

url: http://api.twitter.com/1.1/search/tweets.json?q=%23z25org
content_type: application/json; charset=utf-8
http_code: 401

我得到http_code 401：未经授权的访问。杰森：

{"errors":[{"message":"Could not authenticate you","code":32}]}

这是我的PHP代码:(嗯，最重要的部分）

<?php
// Some characters that need to be replaced
$specialCharacters = array(
    "@"=>"%40",
    "#"=>"%23",
    " "=>"%20",
    ""=>""
);

/*
* Ok, no more config should really be needed. Yay!
*/

// We'll get the URL from $_GET[]. Make sure the url is url encoded, for example encodeURIComponent('statuses/user_timeline.json?screen_name=MikeRogers0&count=10&include_rts=false&exclude_replies=true')
if(!isset($_GET['url'])){
    die('No URL set');
}

$url = $_GET['url'];

// Figure out the URL parmaters
$url_parts = parse_url($url);
parse_str($url_parts['query'], $url_arguments);

$full_url = $config['base_url'].$url; // Url with the query on it.
$base_url = $config['base_url'].$url_parts['path']; // Url without the query.

if (!dbglog(" > ORIGINAL: ".$full_url)) { die("Huh?"); }

// Replace characters
foreach($specialCharacters as $lookup => $replace) {
    $full_url = str_replace($lookup,$replace,$full_url);
}

if (!dbglog(" > REPLACED: ".$full_url)) { die("Huh?"); }

构建this library时，我遇到了同样的问题。

This commit特别可能会提供更多信息。

您基本上遇到的问题是您的URL编码不正确 - 甚至可能是两次。如果您从上面的源代码中查看代码（它非常相似，似乎已经在那里进行了修改），那么它将完全按照您的需要工作。

TLDR：请改用上述单个文件，或者只复制/粘贴代码。这几乎是你想要的。

OP发现：他还尝试将其替换为%2523（其中%25 = %）。我们仍然建议您查看上面的图书馆。
