HP ALM 11使用PHP和cURL上載附件

Question

我需要在HP的ALM 11中上傳附件到測試。為此，我創建了一個基於cURL的自定義PHP函數，以使用ALM的REST API。 這是代碼：

public function attachment($project, $domain, $entity, $id, $filename)
{
    $qc = $this->qc_cookie;
    $ckfile = $this->ckfile;
    $eol = "\n\n";
    $mime_boundary=md5(time());

    $file_to_upload = '--'.$mime_boundary. $eol;
    $file_to_upload .= 'Content-Disposition: form-data; name="filename"';
    $file_to_upload .= $eol;
    $file_to_upload .= $filename;
    $file_to_upload .= $eol;
    $file_to_upload .= $eol;
    $file_to_upload .= '--'.$mime_boundary. $eol;
    $file_to_upload .= 'Content-Disposition: form-data; name="description"';
    $file_to_upload .= $eol;
    $file_to_upload .= 'Test';
    $file_to_upload .= $eol;
    $file_to_upload .= $eol;
    $file_to_upload .= '--'.$mime_boundary. $eol;
    $file_to_upload .= 'Content-Disposition: form-data; name="file"; filename="'.$filename.'"';
    $file_to_upload .= $eol;
    $file_to_upload .= 'Content-Type: text/plain';
    $file_to_upload .= $eol;
    $file_to_upload .= 'Content-Transfer-Encoding: base64' . $eol . $eol;
    $handle = fopen($filename, 'r');
    $file_to_upload .=  fread($handle,filesize($filename));
    $file_to_upload .= $eol;
    $file_to_upload .= '--'.$mime_boundary.'--'. $eol.$eol;
    fclose($handle);

    $header = array("POST /qcbin/rest/domains/".$domain."/projects/".$project."/".$entity.'/'.$id.'/attachments'." HTTP/1.1",
        'Content-Type: multipart/form-data; boundary='.$mime_boundary,
        //'Content-Length: '.strlen($file_to_upload)
        );
    curl_setopt($qc, CURLOPT_HTTPHEADER, $header);   
    curl_setopt($qc, CURLOPT_POSTFIELDS, $file_to_upload); 
    curl_setopt($qc, CURLOPT_COOKIEFILE, $ckfile);
    curl_setopt($qc, CURLOPT_RETURNTRANSFER, true);
    curl_setopt($qc, CURLOPT_URL, $this->url."/qcbin/rest/domains/".$this->domain."/projects/".$this->project."/".$entity."/".$id.'/attachments');
    return curl_exec($qc);
}

當我將請求發送到指定的URL時，我從ALM收到以下錯誤：

<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<QCRestException>
    <Id>qccore.general-error</Id>
    <Title>Illegal multi-part arguments. Attachment wasn't created.</Title>
    <StackTrace>java.lang.IllegalArgumentException: Illegal multi-part arguments. Attachment wasn't created.&#xD;
at org.hp.qc.web.restapi.attachments.AttachmentsResource.createAttachmentMutliPart(AttachmentsResource.java:141)&#xD;

at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:25)&#xD;
at java.lang.reflect.Method.invoke(Method.java:597)&#xD;
...

我想知道我做錯了什么。 我正在遵循API參考中指定的POST字段結構。 謝謝。

Answer 1

我剛剛解決了這個問題而且非常高興。 我的問題是我在標題中用破折號定義邊界，正如它們在正文中被引用一樣。 這不對。

以下是一個適合我的示例（基於REST API文檔）：

頭：

Content-Type: multipart/form-data; boundary=myboundary

身體：

--myboundary
Content-Disposition: form-data; name="filename"

anna.txt
--myboundary
Content-Disposition: form-data; name="file"; filename="anna.txt"

banana
--myboundary--

我仍然無法上傳二進制附件，但這對我來說是一個很大的改進。

編輯 - 以下powershell代碼適用於我上傳任何文件類型：

$contents = gc "my file path"
$body = @"
--boundary
Content-Disposition: form-data; name="filename"

$name
--boundary
Content-Disposition: form-data; name="file"; filename="$name"

$contents
--boundary--
"@

$headers = @{"Content-Length" = $body.Length; "Content-Type" = "multipart/form-data; boundary=$boundary"}

Invoke-RestMethod -Uri "ALM attachment URI" -Method Post -ContentType "multipart/form-data;boundary=boundary" -WebSession $global:session -Body $body

編輯：這是我的上一次更新 - 一個通過REST API成功上傳附件的python函數。 請注意，它是更大的庫的一部分，但希望您明白這一點：

def upload_attachment(self, entity_type, id, file_name):
        """
        Name
            upload_attachment
        Description
            Uploads an attachment to the supplied entity
        Parameters
            entity_type: the entity type - i.e. 'test-instance', 'run', etc.
            id: the integer id of the entity
            file_name: the name of the file in the local filesystem
        Returns
        """
        print 'Uploading attachment to %s id=%s' % (entity_type, id)
        with open(file_name, 'rb') as file:
            bin_data = file.read()
        qurl = '%s/qcbin/rest/domains/%s/projects/%s/%s/%s/attachments' % \
            (self.url, self.domain, self.project, entity_type, id)
        headers = {'Content-Type' : 'multipart/form-data; boundary=uploadboundary'}
        body = """--uploadboundary
Content-Disposition: form-data; name="filename"

%s
--uploadboundary
Content-Disposition: form-data; name="file"; filename="%s"

%s
--uploadboundary--""" % (file_name, file_name, bin_data)

    rsp = self.session.post(qurl, data=body, headers=headers)
    if rsp.status_code != 201:
            raise Exception('Failed to upload %s - code=%s message=%s' % \
            (file_name, rsp.status_code, rsp.text))

我希望有人覺得這很有用。

編輯：代碼無法正常工作，因為它是更大的庫的一部分。 這是一個如何使用內容'Hello !!'發布一個名為'hello.txt'的簡單文本文件的示例 它是用上面的代碼生成的：

頭：

'Content-Type': 'multipart/form-data; boundary=uploadboundary'

身體：

--uploadboundary
Content-Disposition: form-data; name="filename"

hello.txt
--uploadboundary
Content-Disposition: form-data; name="file"; filename="hello.txt"

Hello!!
--uploadboundary--
