使用HTML表单，cURL和PHP将文件上传到Imageshack API [英] Uploading files to Imageshack API using HTML form, cURL and PHP

问题描述

我有一些麻烦上传文件到Imageshack的API。我使用多部分/表单数据形式获取文件。

I am having some trouble uploading files to Imageshack's API. I use a multipart/form-data form to get the file.

index.php：

index.php:

<form method="post" enctype="multipart/form-data" action="upload.php">
    <input type="file" name="fileupload"/>
    <input type="submit" value="Go"/>
</form>

通常我会没有问题，但是数据必须发送到 http://imageshack.us/upload_api.php ，并且响应在其服务器上的XML样式的HTML页面中返回，因此有真的没有什么我可以用它。因此，我决定通过PHP cURL脚本传递表单，并在同一页面上获取响应。

Normally I would have no problem with this, however the data must be sent to http://imageshack.us/upload_api.php and the response is given back in an XML styled HTML page on their server so there's really nothing I can do with it. So I decided to pass the form through a PHP cURL script and getting the response on the same page.

upload.php：

upload.php:

<?php
    $url = 'http://imageshack.us/upload_api.php';
    $key = '4BEILRTV5ff57ecb70867e8becb2c4b5e695bdb4';
    $max_file_size = '5242880';
    $temp = $_FILES["fileupload"]["tmp_name"];
    $name = $_FILES["fileupload"]["name"];

    $ch = curl_init();
    curl_setopt($ch, CURLOPT_HEADER, 0);
    curl_setopt($ch, CURLOPT_VERBOSE, 0);
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
    curl_setopt($ch, CURLOPT_USERAGENT, "Mozilla/4.0 (compatible;)");
    curl_setopt($ch, CURLOPT_URL, $url);
    curl_setopt($ch, CURLOPT_POST, true);

    $post = array(
        "fileupload" => '@' . $temp,
        "key" => $key,
        "max_file_size" => $max_file_size
    );
    curl_setopt($ch, CURLOPT_POSTFIELDS, $post);
    $response = curl_exec($ch);
    echo $response;
?>

一开始我得到了一堆错误，但现在我没有得到任何回应。甚至没有错误。

At first I was getting a bunch of errors, but now I don't get any response. Not even an error.

有关使用此方法的任何建议都非常好！

Any suggestions on using this method would be great!

推荐答案

我不得不在post选项中包含format=>'json'，并使用json_decode来解析信息。这是upload.php脚本。

I had to include "format" => 'json' into the post options and use json_decode to parse the info. Here's the upload.php script.

<?php
    $url = 'http://imageshack.us/upload_api.php';
    $key = '4BEILRTV5ff57ecb70867e8becb2c4b5e695bdb4';
    $max_file_size = '5242880';
    $temp = $_FILES["fileupload"]["tmp_name"];

    $ch = curl_init();
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, true); 
    curl_setopt($ch, CURLOPT_POST, true);
    curl_setopt($ch, CURLOPT_URL, $url);

    $post = array(
        "fileupload" => '@' . $temp,
        "key" => $key,
        "format" => 'json',
        "max_file_size" => $max_file_size,
        "Content-type" => "multipart/form-data"
    );
    curl_setopt($ch, CURLOPT_POSTFIELDS, $post);
    $response = curl_exec($ch);
    $json_a=json_decode($response,true);
    echo $json_a[links][image_link];
?>
