我在 Salesforce Apex 类中使用 IDOL API 将 pdf 文件转换为 html。
当我使用简单的 html 时，例如：
<html>
<body>
<form action="https://api.idolondemand.com/1/api/sync/viewdocument/v1"
method="Post" enctype="multipart/form-data">
<input type="hidden" name="raw_html" value="true"/>
<input type="hidden" name="apikey"
value="{apikey removed}"/>
<input type='FILE' name='file'/><br/>
<input type='submit' name='upload_btn' value='Submit'/>
</form>
</body>
</html>
那么这是有效的。但是当我使用 APEX 代码时httprequest，这是一个错误的请求。
我的 APEX 代码是：
public HTTPResponse uploadFile(Attachment file){
//String boundary = '---------------------\n';
String header = '\n';
header += 'Content-Disposition: form-data; name="file"; filename="'
+ file.Name +'"\nContent-Type: application/pdf\n\n';
String footer = '\n';
String querybody = '\n Content-Disposition: form-data;
name="raw_html"\n\n'+true+'\n';
querybody = querybody + '\n Content-Disposition: form-data;
name="apikey"\n\n {apikey removed} \n\n';
//base64 encoded body
String bodyEncoded = EncodingUtil.base64Encode(file.body);
//last encoded body bytes
String last4Bytes =
bodyEncoded.substring(bodyEncoded.length()-4,bodyEncoded.length());
//if the last 4 bytes encoded base64 ends with the padding character (=
or ==) then re-encode those bytes with the footer
//to ensure the padding is added only at the end of the body
if(last4Bytes.endsWith('='))
{
Blob decoded4Bytes = EncodingUtil.base64Decode(last4Bytes);
HttpRequest tmp = new HttpRequest();
tmp.setBodyAsBlob(decoded4Bytes);
String last4BytesFooter = tmp.getBody()+footer;
bodyEncoded = querybody + header +
bodyEncoded.substring(0,bodyEncoded.length()-4) +
EncodingUtil.base64Encode(Blob.valueOf(last4BytesFooter)) +
footer;
}
else
{
bodyEncoded = querybody + header + bodyEncoded + footer;
}
bodyEncoded = querybody;// + header + bodyEncoded + footer;
System.debug('>>>>>>>>>>>>>>>>>>>>>>' + bodyEncoded);
HttpRequest req = new HttpRequest();
req.setHeader('Content-Type','multipart/mixed');
req.setMethod('POST');
req.setEndpoint('https://api.idolondemand.com/1/api/sync/viewdocument/v1'
);
req.setBody(bodyEncoded);
req.setTimeout(120000);
req.setHeader('Content-Length', String.valueof(req.getBody().length()));
Http http = new Http();
Httpresponse res = http.send(req);
return res;
}
我的视觉力量页面仅包含：
<apex:page controller="IDOLService">
<apex:form >
<apex:pageBlock title="File Input">
<apex:pageBlockSection >
<apex:pageBlockSectionItem >
<apex:inputFile value="{!file.body}" filename="{!file.Name}"/>
<apex:commandButton action="{!showPreview}" value="Show Preview"/>
</apex:pageBlockSectionItem>
</apex:pageBlockSection>
</apex:pageBlock>
<apex:outputpanel id="docpanel">
{!result}
</apex:outputpanel>
</apex:form>
</apex:page>
这给了我 7005 错误，错误的请求。
