我需要为用户登录创建一个发布请求。我正在设置 Content-Length 标头，但是当我发布请求时，它会给出org.apache.http.client.HttpResponseException: Length Required

我的代码

        DefaultHttpClient httpclient = new DefaultHttpClient();

        JSONObject data = new JSONObject();
        data.put("UserName", username);
        data.put("Password", password);
        data.put("RememberMe", false);

        HttpPost httpost = new HttpPost(LOGIN_PATH);
        StringEntity se = new StringEntity(data.toString());
        httpost.setEntity(se);

        httpost.setHeader("Accept", "application/json");
        httpost.setHeader("Content-Type", "application/json");
        httpost.setHeader("Content-Length",""+se.getContentLength());

        ResponseHandler responseHandler = new BasicResponseHandler();
        return httpclient.execute(httpost, responseHandler);

当我设置 Content-Length 标头时，它给出“Content-Length 标头已经存在”，当删除 content-length 标头时，它给出“需要长度”

谢谢。

改变

 httpost.setHeader("Content-Lenght",""+se.getContentLength());

至

 httpost.setHeader("Content-Length",""+se.getContentLength());

因为目前您正在传递Content-Lenght（长度拼写错误）而不是Content-Length 作为setHeader方法的关键
