java http post 怎么设置 raw格式

调试微信推广支持中二维码生成api的接口，使用chrome浏览器的postman插件，post请求时有一个选项是form-data，或者raw，使用raw可以请求成功，from-data不知道怎么组装key和value所以一直失败。非常不明白raw是什么意思，google百度都没有相关的解释。后来研究发现，其实raw方式使用的是纯字符串的数据上传方式，所以在POST之前，可能需要手工的把一些json/text/xml格式的数据转换成字符串，是一种post原始请求，区别于form-data这种常用的key-value方式。
public static String result; public static void httpTest() throws ClientProtocolException, IOException { String token = "R5amyr6NyXCtWdScmNiuvVwBCJztfByZDUGaE2V0NwOUheW4XYlvUusYkrViTYt584RgcyXRhjxAJZG3rFlPLg"; String url = "https://api.weixin.qq.com/cgi-bin/qrcode/create?access_token=" + token; String json = "{"action_name":"QR_LIMIT_SCENE","action_info":{"scene":{"scene_id":234}}}"; HttpClient httpClient = new DefaultHttpClient(); HttpPost post = new HttpPost(url); StringEntity postingString = new StringEntity(json);// json传递 post.setEntity(postingString); post.setHeader("Content-type", "application/json"); HttpResponse response = httpClient.execute(post); String content = EntityUtils.toString(response.getEntity()); // Log.i("test",content); System.out.println(content); result = content; }

以上代码中需要导入

import org.apache.http.HttpResponse; import org.apache.http.client.ClientProtocolException; import org.apache.http.client.HttpClient; import org.apache.http.client.methods.HttpPost; import org.apache.http.entity.StringEntity; import org.apache.http.impl.client.DefaultHttpClient; import org.apache.http.util.EntityUtils;

Android中自带org.apache.http相关库文件，所以可以快捷键(ctrl+shift+o)一次导入成功。

服务器端对提交的数据的具体要求是怎样的 ~ ~

public static String result; public static void httpTest() throws ClientProtocolException, IOException { String token = "R5amyr6NyXCtWdScmNiuvVwBCJztfByZDUGaE2V0NwOUheW4XYlvUusYkrViTYt584RgcyXRhjxAJZG3rFlPLg"; String url = "https://api.weixin.qq.com/cgi-bin/qrcode/create?access_token=" + token; String json = "{\"action_name\":\"QR_LIMIT_SCENE\",\"action_info\":{\"scene\":{\"scene_id\":234}}}"; HttpClient httpClient = new DefaultHttpClient(); HttpPost post = new HttpPost(url); StringEntity postingString = new StringEntity(json);// json传递 post.setEntity(postingString); post.setHeader("Content-type", "application/json"); HttpResponse response = httpClient.execute(post); String content = EntityUtils.toString(response.getEntity()); // Log.i("test",content); System.out.println(content); result = content; }
