请求报文示例 请求报文示例

1. // request.js https://XXXXXXXX/XXX/yy/yyy
2. var API_URL = 'https://XXXXXXXX/XXX/'
3. function request(method, requestHandler) {
4. var api_key = 'XXX' //用于加密的key
5. var APPEND_URL = requestHandler.url
6. var tradeId = requestHandler.tradeId
7. // 获取当前时间戳
8. var timestamp = getDate(new Date)
9. var param = {
10. "head": {

12. "tradeId": tradeId,
13. "validCode": "",

15. // "token" : wx.getStorageSync('token')
16. },
17. "body": {

26. plainStr = head_dic.tradeId + head_dic.timestamp +head_dic.userId+head_dic.token+api_key
27. } else {
28. plainStr = head_dic.tradeId + head_dic.timestamp +api_key
29. }
30. var validCode1 = utilMd5.hexMD5(plainStr) // md5加密
31. var validCode = validCode1.toUpperCase()
32. head_dic.validCode = validCode
33. param.head = head_dic
34. param.body = requestHandler.params
35.  
36. wx.request({
37. url: API_URL + APPEND_URL+'.json',
38. data: { param: JSON.stringify(param) }, //json转son字符串
39. method: method, // OPTIONS, GET, HEAD, POST, PUT, DELETE, TRACE, CONNECT
40. header: {
41. 'content-Type': 'application/x-www-form-urlencoded'
42. }, // 设置请求的 header
43.  
44. success: function (res) {
45. //注意：可以对参数解密等处理
46. requestHandler.success(res)
47. },
48. fail: function () {
49. requestHandler.fail()
50. },
51. complete: function () {
