Question

我需要将Apache HttpComponents用于其HttpMime多部分库。但是，当使用HttpComponents和库存java.net类显示完全相同的来电时，HttpComponents会失败：

private void getUrl(URI targeturl, String token) throws IOException {

    String AUTH = "Authorization";
    String OAUTH = "OAuth ";

    System.out.println("Impl1:");
    HttpGet htg = new HttpGet(targeturl);
    htg.addHeader(AUTH, OAUTH + token);
    HttpResponse response = new DefaultHttpClient().execute(new HttpGet(targeturl));
    System.out.println(response);
    String resp = EntityUtils.toString(response.getEntity());
    System.out.println(resp);

    System.out.println("\nImpl 2:");
    HttpURLConnection conn = (HttpURLConnection) uriToUrl(targeturl).openConnection();
    conn.setDoOutput(true);
    conn.setRequestMethod("GET");
    conn.setRequestProperty(AUTH, OAUTH + token);
    System.out.print(conn.getResponseCode());
    System.out.println(" " + conn.getResponseMessage());

    StringWriter writer = new StringWriter();
    IOUtils.copy(conn.getInputStream(), writer);
    System.out.println(writer.toString());
}

//for known good uris ONLY
private URL uriToUrl(URI uri) {
    try {
        return uri.toURL();
    } catch (MalformedURLException mue) {
        throw new Error(mue); //something is seriously fuxxored
    }
}

结果输出为：

Impl1:
HTTP/1.1 401 Unauthorized [Access-Control-Allow-Headers: Authorization, Access-Control-Allow-Methods: POST, GET, PUT, DELETE, OPTIONS, Access-Control-Allow-Origin: *, Content-Length: 51, Content-Type: application/json, Date: Sat, 20 Jul 2013 00:03:42 GMT]
{"status":401,"data":null,"error":["Unauthorized"]}

Impl 2:
200 OK
{"status":200,"data":{...},"error":null}

HttpComponents是客户端4.2.5，核心4.2.4，java是1.6.0-24。设置看起来与我相同，但必须有一些区别。它是什么？

Answer 1

这是一个愚蠢的编码错误。

HttpResponse response = new DefaultHttpClient().execute(new HttpGet(targeturl));

应该是

HttpResponse response = new DefaultHttpClient().execute(htg);

Apache HttpComponents失败，HttpURLConnection适用于同一个调用
