如何在 Android 中设置选项 Header 和 HTTP POST 请求中的内容

Question

我在 Android 中使用了 HttpPost 和 HttpURLConnection 来发送带有以下 Headers 和内容的请求：

Headers: api_key: 9a8akx8badkaxxxx, 速度：0，声音：男，韵律：1， Cache-Control: no-cache

内容（Content-Type：text/plain）：大家好

这些是我的代码： *使用 HttpPost：

        HttpClient client = new DefaultHttpClient();
        HttpPost post = new HttpPost(requestURL);
        post.addHeader("api_key", "9a8akx8badkaxxxx");
        post.addHeader("speed", "0");
        post.addHeader("voice", "male");
        post.addHeader("prosody", "1");
        post.addHeader("Cache-Control", "no-cache");
        List <NameValuePair> nvps = new ArrayList <NameValuePair>();
        nvps.add(new BasicNameValuePair("data[body]", "Hello everyone"));
        AbstractHttpEntity ent= null;

        ent = new UrlEncodedFormEntity(nvps, HTTP.UTF_8);

        ent.setContentType("application/x-www-form-urlencoded; charset=UTF-8");
        ent.setContentEncoding("UTF-8");
        post.setEntity(ent);
        post.setURI(new URI("http://api.openfpt.vn/text2speech/v4"));
        HttpResponse response =client.execute(post);

*使用 HttpURLConnection:

    URL url = new URL(requestURL);
    HttpURLConnection conn = (HttpURLConnection) url.openConnection();
    conn.setDoOutput(true);
    conn.setInstanceFollowRedirects(false);
    conn.setRequestMethod("POST");
    conn.setRequestProperty("api_key", "9a8akx8badkaxxxx");
    conn.setRequestProperty("Content-Type", "text/plain");
    conn.setRequestProperty("speed", "0");
    conn.setRequestProperty("voice", "male");
    conn.setRequestProperty("prosody", "1");
    conn.setRequestProperty("Cache-Control", "no-cache");

然后不知道把内容"Hello everyone"放入HttpURLConnection

的方法

结果总是出错。但是当我在 Firefox 中使用 add-on HttpRequester 时，响应正常。请帮助我在 Android

中创建和设置 Http 请求

Answer 1

试试这个来设置 content-type:

        HttpPost httppost = new HttpPost(builder.getUrl());
        httppost.setHeader(HTTP.CONTENT_TYPE,
                "text/plain;charset=UTF-8");

要任意设置headers，我觉得应该是这样的：

        httppost.setHeader("api_key", "9a8akx8badkaxxxx");
        httppost.setHeader("speed", "0");
        httppost.setHeader("voice", "male");
        httppost.setHeader("voice", "male");
        httppost.setHeader("prosody", "1");
        httppost.setHeader("Cache-Control", "no-cache");

要发送数据，请为您的 post 字段选择一个名称（此处为 Fn 和 IdDevice）：

        List<NameValuePair> nameValuePairs = new ArrayList<>(1);
        // nameValuePairs.add(new BasicNameValuePair("Fn",function));
        // nameValuePairs.add(new BasicNameValuePair("IdDevice",IdDevice));

编辑开始

         nameValuePairs.add(new BasicNameValuePair("Content","Hello everyone"));

编辑结束

        httppost.setEntity(new UrlEncodedFormEntity(nameValuePairs));

最后，执行 post 请求：

        // Execute HTTP Post Request
        HttpResponse response = httpclient.execute(httppost);
