创建应用

记下自己的 APIkey和 Secret Key写入代码对应的位置

代码如下：

# coding=utf-8

import sys
import json

# 保证兼容python2以及python3
IS_PY3 = sys.version_info.major == 3
if IS_PY3:
    from urllib.request import urlopen
    from urllib.request import Request
    from urllib.error import URLError
    from urllib.parse import urlencode
    from urllib.parse import quote_plus
else:
    import urllib2
    from urllib import quote_plus
    from urllib2 import urlopen
    from urllib2 import Request
    from urllib2 import URLError
    from urllib import urlencode

# 替换你的 API_KEY
API_KEY = '你的APIKEY'

# 替换你的 SECRET_KEY
SECRET_KEY = '你的Secret Key'

# 信息内容文本
TEXT = "这里填写你要转成语音的文字"

TTS_URL = 'http://tsn.baidu.com/text2audio'

"""  TOKEN start """

TOKEN_URL = 'http://openapi.baidu.com/oauth/2.0/token'
# 发音人选择, 基础音库：0为度小美，1为度小宇，3为度逍遥，4为度丫丫，

# 语速，取值0-15，默认为5中语速

    tex = quote_plus(TEXT)  # 此处TEXT需要两次urlencode

    params = {'tok': token, 'tex': tex, 'per':PER,'cuid': "quickstart",
              'lan': 'zh', 'ctp': 1}  # lan ctp 固定参数

    data = urlencode(params)

    req = Request(TTS_URL, data.encode('utf-8'))
    has_error = False
    try:
        f = urlopen(req)
        result_str = f.read()

        headers = dict((name.lower(), value) for name, value in f.headers.items())

        has_error = ('content-type' not in headers.keys() or headers['content-type'].find('audio/') < 0)
    except  URLError as err:
        print('http response http code : ' + str(err.code))
        result_str = err.read()
        has_error = True

    import time
    localtime = time.localtime(time.time())
    time = str(time.strftime('%Y%m%d%H%M%S',time.localtime(time.time())))
    save_file = "errorinfo.txt" if has_error else time+'.mp3'

    with open(save_file, 'wb') as of:
        of.write(result_str)

    if has_error:
        if (IS_PY3):
            result_str = str(result_str, 'utf-8')
        print("api error:" + result_str)

    print("file saved as : " + save_file)

运行后会生成一个时间名称的 MP3，相关的参数我已经在代码里写了注释，需要的话加入到代码91行 的 params里就可以了

如果报以下错误信息是因为百度申请的资源还没下来，或者你还没有申请免费资源。
{"err_detail":"16: Open api characters limit reached","err_msg":"16: Open api characters limit reached","err_no":502,"err_subcode":16,"tts_logid":3405513447}

有问题留言或私信的可以一起研究。
