下面是androidstudio發(fā)送json數(shù)據(jù)的代碼，應(yīng)該是發(fā)送成功了，但是arduino顯示"parseObject()?failed" public?void?openLed(){ ????String?url?=?"http://api.heclouds.com/cmds?device_id=xxxxxxxx"; ????RequestParams?params?=?new?RequestParams(url); ????params.addHeader("api-key","xxxxxxxxx"); ????params.addHeader("Content-Type","application/x-www-form-urlencoded;?charset=UTF-8"); ????params.addHeader("accept",?"*/*"); ????params.addHeader("Connection",?"Keep-Alive"); ????params.addHeader("Charset",?"UTF-8"); ????params.addBodyParameter("code","led-0"); ????x.http().post(params,?new?Callback.CommonCallback<String>()?{ ????????@Override ????????public?void?onSuccess(String?result)?{ ????????????Log.e("bean",result); ????????} ????????@Override ????????public?void?onError(Throwable?ex,?boolean?isOnCallback)?{ ????????????Log.e("bean","error"); ????????} ????????@Override ????????public?void?onCancelled(CancelledException?cex)?{ ????????} ????????@Override ????????public?void?onFinished()?{ ????????????Log.e("bean","finish"); ????????} ????}); } 下面是arduinoIDE解析json數(shù)據(jù)代碼： void?parseOneNetMqttResponse(char*?payload){ ???Serial.println("start?parseOneNetMqttResponse"); ??????StaticJsonBuffer<300>?jsonBuffer; ???????//?StaticJsonBuffer?在棧區(qū)分配內(nèi)存???它也可以被?DynamicJsonBuffer（內(nèi)存在堆區(qū)分配）?代替 ????????//?DynamicJsonBuffer??jsonBuffer; ??????JsonObject&?root?=?jsonBuffer.parseObject(payload); ??????//?Test?if?parsing?succeeds. ???????if?(!root.success()) ???????{???????Serial.println("parseObject()?failed");???????return?;???} ????????String?code?=?root["code"]; ???????????if(strcmp(code.c_str(),"code=led-1")==0) ???????????{?????????????i=1;digitalWrite(D7,?LOW);????????} ????????????else?if(strcmp(code.c_str(),"code=led-0")==1) ????????????{????????????i=0;digitalWrite(D7,?HIGH);????????} ????????}
