| 1 | +> 最近在写一个小项目，需要涉及到前端向后端发送一个jsonArray，然后我们后端采用的是node的koa框架，所以需要用http发送，然后这个http包含着一个content即可 |

|
| 3 | +```` |
| 4 | +移动端的发送代码 |
| 5 | +
|
| 6 | +JSONArray jsonArray = new JSONArray(); |
| 7 | + for (int i = 0; i < 5; i++) { |
| 8 | + JSONObject object = new JSONObject(); |
| 9 | + try { |
| 10 | + object.put("user_id", "11111111111"); |
| 11 | + object.put("user_name", "2222222222"); |
| 12 | + object.put("user_phone", "33333333333"); |
| 13 | + object.put("user_address", "444444444444"); |
| 14 | + object.put("product_id", "5555555555"); |
| 15 | + object.put("product_name", "666666666666"); |
| 16 | + object.put("product_price", "77777777777"); |
| 17 | + object.put("product_count", "88888888888"); |
| 18 | + } catch (JSONException e) { |
| 19 | + Log.i("lin", "---lin's log---> 进入 catch"); |
| 20 | + e.printStackTrace(); |
| 21 | + } |
| 22 | + jsonArray.put(object); |
| 23 | + } |
| 24 | + String content = jsonArray.toString(); |
| 25 | + OkHttpUtils |
| 26 | + .postString() |
| 27 | + .url("http://172.20.10.4:3008/testjson") |
| 28 | + .content(content) |
| 29 | + .build() |
| 30 | + .execute(new StringCallback() { |
| 31 | + @Override public void onError(Request request, Exception e) { |
| 32 | + Toast.makeText(TestActivity.this, "error", Toast.LENGTH_SHORT).show(); |
| 33 | + Log.i("lin", "---lin's log---> error " + e.toString()); |
| 34 | + } |
| 35 | +
|
| 36 | + @Override public void onResponse(String response) { |
| 37 | + Toast.makeText(TestActivity.this, "onResponse", Toast.LENGTH_SHORT).show(); |
| 38 | + Log.i("lin", "---lin's log---> response " + response); |
| 39 | + } |
| 40 | + }); |
| 41 | +
|
| 42 | +
|
| 43 | +```` |
| 44 | + |
| 45 | + |
| 46 | +后端接收的代码： |
| 47 | + |
| 48 | +```` |
| 49 | +var koa = require('koa'); |
| 50 | +var controller = require('koa-route'); |
| 51 | +var parse = require('co-body'); |
| 52 | +var app = koa(); |
| 53 | +
|
| 54 | +app.use(controller.post('/testjson', function*() { |
| 55 | + console.log("接收到请求~"); |
| 56 | + var item = yield parse(this); |
| 57 | + var jsonList = eval(item); |
| 58 | + for (var i = 0; i < jsonList.length; i++) { |
| 59 | + console.log(jsonList[i].user_id); |
| 60 | + console.log(jsonList[i].user_name); |
| 61 | + } |
| 62 | +
|
| 63 | + this.set('Cache-Control', 'no-cache'); |
| 64 | + this.body = "100"; |
| 65 | +})); |
| 66 | +
|
| 67 | +
|
| 68 | +
|
| 69 | +
|
| 70 | +```` |
| 71 | + |
| 72 | + |
| 73 | + |
| 74 | + |
| 75 | +以上便可以实现，前端向后端发送jsonArray并将其解析的过程啦~ |
