如何在Android中的HTTP POST请求中设置选项标头和内容 [英] How to set the option Header and Content in HTTP POST Resquest in Android

问题描述

我在Android中使用HttpPost和HttpURLConnection发送带有以下标头和内容的请求:

I used HttpPost and HttpURLConnection in Android to send the request with following Headers and Contents:

标题:api_key:9a8akx8badkaxxxx，速度:0，声音:男，韵律:1，缓存控制:无缓存

Headers: api_key: 9a8akx8badkaxxxx, speed: 0, voice: male, prosody: 1, Cache-Control: no-cache

内容(内容类型:文本/纯文本):大家好

Contents (with Content-Type: text/plain): Hello everyone

这些是我的代码:*使用HttpPost:

These are my code: *Using the 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:

*Using the 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");

然后我不知道将内容"Hello Everyone"放入HttpURLConnection的方法

and then I don't know the method to put the content "Hello everyone" into HttpURLConnection

结果总是错误.但是，当我在Firefox中使用附加的HttpRequester时，响应就可以了.请帮助我在Android中创建和设置Http请求

The result always error. But when I use the add-on HttpRequester in Firefox, the response is OK. please help me to create and set Http Request in Android

推荐答案

尝试使用此方法设置内容类型:

Try this to set the content-type:

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

要设置任意标头，我认为应该这样做:

To set arbitrary headers, I believe it should be done like this:

        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，请为您的帖子字段选择一个名称(此处为Fn和IdDevice):

To send the data, choose a name for your post field (here Fn and 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，执行发布请求:

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