从java端上传文件到REST是可行的，而不是从python

我们正在测试Saperion REST web服务，除文件上传外，一切正常。java方面一切正常：

public HttpResponse insertDocument(String docId) throws IOException {

    RestClient client = new RestClient();

    byte[][] file1 = null;
    System.out.println("insertDocument: Reading attachment files to insert...");
    try {

        file1 = new byte[][]
                {

                 client.readFile("/usr/local/www/test.pdf")

                };

    } catch (Exception ex) {
        System.out.println("******** insertDocument catch ******");
        System.out.println("insertDocument: File not read...");
        System.out.println("insertDocument: Error: " + ex.getMessage());
    }

    HttpClient httpclient = new DefaultHttpClient();

    try {
        String url = SERVER + INSERT_DOCUMENT_OPERATION;
        System.out.println("insertDocument: url - " + url + "/" + docId);

        HttpPost httpPost = new HttpPost(url);
        httpPost.setHeader("Accept", "text/plain");
        httpPost.setHeaders(getAuthentication());


        // META
        String str = "<query id=\"001\">" +
                "<docid>" + docId + "</docid>" +
                "<dochead>" +
                "</dochead>" +
                "<attachments count=\"" + file1.length + "\">";


        for (int i = 0; i < file1.length; i++) {
            str += "<entry><filename>" + docId + "_" + i + ".pdf" + "</filename>" +
                    "<filedata/>" +
                    "</entry>";
        }

        str += "</attachments>" +
                "</query>";

        System.out.println("insertDocument: str - " + str);

        MultipartEntity entity = new MultipartEntity();
        entity.addPart("xmlString", new StringBody(str));

        for (byte[] file : file1)
            entity.addPart("file", new ByteArrayBody(file, "file"));

        httpPost.setEntity(entity);


        HttpResponse response = httpclient.execute(httpPost);

        System.out.println("insertDocument: return response ...");
        return response;

    } finally {
        httpclient.getConnectionManager().shutdown();
    }
}

public HttpResponse insertDocument（字符串docId）引发IOException{
RestClient=newrestclient（）；
字节[][]file1=null；
System.out.println（“插入文档：读取要插入的附件文件…”）；
试一试{
file1=新字节[][]
{
client.readFile（“/usr/local/www/test.pdf”）
};
}捕获（例外情况除外）{
System.out.println（“*********insertDocument catch*******”）；
System.out.println（“insertDocument:File not read…”）；
System.out.println（“insertDocument:Error:+ex.getMessage（））；
}
HttpClient HttpClient=新的DefaultHttpClient（）；
试一试{
字符串url=服务器+插入文档\u操作；
System.out.println（“insertDocument:url-”+url+“/”+docId）；
HttpPost HttpPost=新的HttpPost（url）；
httpPost.setHeader（“接受”、“文本/普通”）；
setHeaders（getAuthentication（））；
//元
字符串str=“”+
“”+docId+“”+
"" +

"";
for（int i=0；i

因此，java和python请求的内容实际上是相同的，但java上传成功，但python生成的404未找到。

您的帖子URL在java和python中是不同的。在java中是

/saperion/services/rest/insertDocument

，而在python中是

http://appdevel4.kada.lan/saperion/services/rest/insertDocument/56

。在进行比较之前，请确保您的请求是相同的。

谢谢：）在Python中只保留insertDocument修复了该问题。谢谢：）在Python中只保留insertDocument修复了该问题。
