Question

我尝试通过cts：uri-match返回所有文档。不仅是uri，还有整个文档。所以我在/ app / customer /中放了一些文档，现在我创建了这个REST API扩展端点。但是当我无法通过这些文件返回实际文件时。

看起来我的查询正在运行（＆＃34;产生6个结果＆＃34;）但输出格式错误。

这是我的错误：

<rapi:error 
    xmlns:rapi="http://marklogic.com/rest-api">
    <rapi:status-code>400</rapi:status-code>
    <rapi:status>Bad Request</rapi:status>
    <rapi:message-code>RESTAPI-INVALIDRESULT</rapi:message-code>
    <rapi:message>RESTAPI-INVALIDRESULT: (err:FOER0000) Invalid result:  reason: GET     extension produced 6 results and 1 mime types: customers</rapi:message>
</rapi:error>

这是我的扩展程序：

xquery version "1.0-ml";

module namespace foo = "http://marklogic.com/rest-api/resource/customers";
declare namespace roxy = "http://marklogic.com/roxy";
declare namespace pub = "http://acme.com/foo/publisher/1.0";

declare 
%roxy:params("id=xs:string")

function foo:get(
    $context as map:map,
    $params  as map:map
) as document-node()*
{
    map:put($context, "output-types", "application/xml"),
    xdmp:set-response-code(200, "OK"),
    foo:getCustomersByXPath($params)
};

declare function foo:getCustomersByXPath(
    $params  as map:map
) as document-node()* {
    let $set := cts:uri-match("/app/customer/*")
    let $id := map:get($params,"id")
    for $x in doc($set)
    return doc($x)            
};

检查目录中的数据：

http://myserver:myport/v1/search?q=&directory=/app/customer/

结果：

Answer 1

get（）扩展函数可以返回多个文档，这些文档可以有不同的mime类型。

尝试将output-types键设置为每个返回文档具有一个mime类型字符串的序列。在您的情况下，可能是每个字符串都是＆＃34; application / xml＆＃34;
