android - 在 android 中使用 HttpPost 发布 JsonArray 和字符串参数

Question

我尝试了很多使用 HttpPost 发送数据的方法，但我没有成功，如果有人知道这个请帮忙？

我的服务网址是:
http://xxxxx/xxx/abc.php?id=xx&name=xxx&data=[{.....}]

当我从浏览器中点击时它工作正常但从我的代码 data=[{}] 没有发送。

我最后的尝试是:
1--->

String serviceUrl = "http://xxxxx/xxx/abc.php"; 


DefaultHttpClient httpClient = new DefaultHttpClient();
        HttpPost httpPost = new HttpPost(serviceUrl);
        httpPost.setHeader("id", "xx");
        httpPost.setHeader("name", "xxx");
        httpPost.setHeader("Content-Type", "application/json");
        StringEntity entity = new StringEntity(jsonArr.toString(), HTTP.UTF_8);
        httpPost.setEntity(entity);
        HttpResponse httpResponse = httpClient.execute(httpPost);
        HttpEntity httpEntity = httpResponse.getEntity();
        json_str = EntityUtils.toString(httpEntity);

2--->

ArrayList<NameValuePair> nameValuePairs = new ArrayList<NameValuePair>();
    nameValuePairs.add(new BasicNameValuePair("id", "xx") );
    nameValuePairs.add(new BasicNameValuePair("name", "xxx"));      
    nameValuePairs.add(new BasicNameValuePair("data", jsonArr.toString()));

        DefaultHttpClient httpClient = new DefaultHttpClient();
        HttpPost httpPost = new HttpPost(serviceUrl);
        httpPost.setHeader("Content-Type", "application/json"); 
        StringEntity entity = new StringEntity(nameValuePairs.toString(), HTTP.UTF_8);
        httpPost.setEntity(entity);
        HttpResponse httpResponse = httpClient.execute(httpPost);
        HttpEntity httpEntity = httpResponse.getEntity();
        json_str = EntityUtils.toString(httpEntity);

3--->

ArrayList<NameValuePair> nameValuePairs = new ArrayList<NameValuePair>();
nameValuePairs.add(new BasicNameValuePair("id", "xx") );
nameValuePairs.add(new BasicNameValuePair("name", "xxx"));
DefaultHttpClient httpClient = new DefaultHttpClient();
HttpPost httpPost = new HttpPost(serviceUrl);
httpPost.setHeader("Content-Type", "application/json");
httpPost.setEntity(new UrlEncodedFormEntity(nameValuePairs));   
StringEntity entity = new StringEntity(jsonArr.toString(), HTTP.UTF_8);
httpPost.setEntity(entity);
HttpResponse httpResponse = httpClient.execute(httpPost);
HttpEntity httpEntity = httpResponse.getEntity();
json_str = EntityUtils.toString(httpEntity);

输出:得到的响应与我在浏览器上使用 url 'http://xxxxx/xxx/abc.php?id=xx&name=xxx'(没有数据参数)得到的响应相同，我认为这意味着 data=[{}] 没有使用我的代码中的 simple_string_parameters 发送。

Answer 1

Tried lot of way to send data using HttpPost but not succeed

=> 是的，这很明显，因为您的网络服务 URL 遵循的是 GET 方法，而不是 POST。

http://xxxxx/xxx/abc.php?id=xx&name=xxx&data=[ {.....}]

所以我建议您尝试使用 HTTPGet 方法而不是 HTTPPost。
