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，但都没有成功，如果有人知道，请帮忙？

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

当我从浏览器点击但我的代码data=[{}] 没有发送时，它工作正常。

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'（不带数据参数）得到的响应相同， 我的意思是 data=[{}] 没有从我的代码中使用 simple_string_parameters 发送。

Answer 1

尝试了很多使用 HttpPost 发送数据的方法，但没有成功

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

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

所以我建议你尝试HTTPGet 方法而不是HTTPPost。

检查adding parameters to a HTTP GET request in Android这个答案？
