消息推送，也就是用戶向公眾賬號發送的消息的類型，目前支持的有文本、圖片、地理位置、鏈接、事件消息等五種，公眾賬號的回復消息有三種，文本、音樂、圖文。

我開發兩個公眾平臺的應用，一個是天氣寶寶，一個是翻譯寶寶，其中天氣寶寶返回的是圖文信息、翻譯寶寶返回的是文字信息，截圖如下：

?

接下來將以這兩個應用為例講解公眾平臺應用的開發。

翻譯寶寶使用的是有道翻譯的api，但是有道翻譯的api是有使用限制的，每個小時不超過1000次，對于大部分人來說，這已經夠了，申請的地址：http://fanyi.youdao.com/openapi?path=data-mode?，申請完后就有API Key了。

下面是翻譯寶寶第一版本的源碼：

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52 53 54 55 56 57 58 59 60 61 62 63 64 65 66 67 68 69 70 71 72 73 74 75 76 77 78 79 80 81 82 83 84 85 86 87 88 89 90 91 92 93 94 95 96 97 98 99 100 101 102 103 104 105 106 107 108 109 110 111 112 113 114 115 116 117 118 119 120 121 122 123 124 125 126 127
