我只是从服务器获取标头，二进制数据和TTSStatus，但现在我得到的只是标头，二进制，标头，二进制和TTSStatus.当我刚从服务器获取标头，二进制数据和TTSStatus时，以下代码可以正常工作.
I was just getting a header, binary data and TTSStatus from the server but now I am getting as above nothing but getting header, binary, header, binary and TTSStatus. The below code is working fine when I was just getting a header, binary data and TTSStatus from the server.
有人可以告诉我如何进行修改吗?
Can someone please tell me how to modify it ?
for part in msg.walk():
content_type = part.get_content_type()
payload = part.get_payload()
try:
#if there is no reference file exist then create one based on the response
if content_type == "audio/x-wav" and len(payload):
ref_filename = get_filename('pcm', output_filename + '_ref', outputfolder)
if not os.path.exists(ref_filename):
with open(ref_filename, 'wb') as f_pcm:
f_pcm.write(payload)
else:
print "[Warning] Reference PCM file is already there"
cur_filename = get_filename('pcm', output_filename, outputfolder)
if len(cur_filename):
with open(cur_filename, 'wb') as f_pcm:
f_pcm.write(payload)
else:
print "[ERROR] Not able to create a Response PCM file \n"
Error_Status = compare_files(ref_filename, cur_filename)
#copy the header or the json response from the server
elif content_type == "application/json":
with open(get_filename('json', output_filename, outputfolder), 'w') as f_json:
f_json.write(payload)
except:
print "\n[ERROR] Can't Create Reference PCM or Response JSON files!"
Error_Status = 1
推荐答案
看来您有时会为每个请求找回两个PCM块.以前，第二个条目为空.
It appears you are sometimes getting two PCM blocks back for each request. Previously the second entry was empty.
以下内容将在每个文件的末尾添加一个段号.它基于我的原始代码，因此您需要将更改应用于当前的完整脚本:
The following will add a segment number to the end of each file. It is based on my original code, so you will need to apply the changes to your full current script:
data = "MIME-Version: 1.0\nContent-Type: {}\n{}".format(res.getheader('content-type'), res.read())
msg = email.message_from_string(data)
segment = 1
for part in msg.walk():
content_type = part.get_content_type()
payload = part.get_payload()
if content_type == "audio/x-wav" and len(payload):
pcm_filename = '{}_{}'.format(output_filename, segment)
segment += 1
ref_filename = get_filename('pcm', pcm_filename + '_ref', LNG)
if not os.path.exists(ref_filename):
with open(ref_filename, 'wb') as f_pcm:
f_pcm.write(payload)
cur_filename = get_filename('pcm', pcm_filename, LNG)
with open(cur_filename, 'wb') as f_pcm:
f_pcm.write(payload)
compare_files(ref_filename, cur_filename)
elif content_type == "application/json":
with open(get_filename('json', output_filename, LNG), 'w') as f_json:
f_json.write(payload)
您还可以更改以下行:
output_filename = "".join([x if x.isalnum() else "_" for x in required_text[:80]]).replace('__', '_').strip('_')
这将具有从输出文件名中删除所有双下划线或尾随下划线的作用.
This will have the effect of removing any double underscores or trailing underscores from your output file names.
或者，如果要将所有段附加在一起，则可以尝试以下版本.不幸的是，我无法重新创建多段响应，因此无法对其进行测试，以查看是否可以将各个段附加在一起并使其仍然正确播放:
Alternatively, if you want to append all of the segments together, you could try something like the following version. Unfortunately, I was not able to recreate the multi-segment response and so was not able to test this to see if it is possible to just append the various segments together and for it to still play correctly:
data = "MIME-Version: 1.0\nContent-Type: {}\n{}".format(res.getheader('content-type'), res.read())
msg = email.message_from_string(data)
wav_data = []
for part in msg.walk():
content_type = part.get_content_type()
payload = part.get_payload()
if content_type == "audio/x-wav" and len(payload):
wav_data.append(payload)
elif content_type == "application/json":
with open(get_filename('json', output_filename, LNG), 'w') as f_json:
f_json.write(payload)
if len(wav_data):
payload = ''.join(wav_data)
ref_filename = get_filename('pcm', output_filename + '_ref', LNG)
if not os.path.exists(ref_filename):
with open(ref_filename, 'wb') as f_pcm:
f_pcm.write(payload)
cur_filename = get_filename('pcm', output_filename, LNG)
with open(cur_filename, 'wb') as f_pcm:
f_pcm.write(payload)
compare_files(ref_filename, cur_filename)
