Question

以下一组代码在我有短文本但我给它一个更长的文本时会有效：https://pastebin.com/PLinyN65

import os
import json
from watson_developer_cloud import ToneAnalyzerV3 
from glob import glob

with open(credentials.txt) as cred:
    data = cred.readlines()
    UserName = data[0]
    PassWord = data[1]

tone_analyzer = ToneAnalyzerV3(
                username=UserName,
                password=PassWord,
                version='2016-05-19')

pth = '../input/*.txt'
txtFiles = glob(pth)
for file in txtFiles:
    baseName = os.path.basename(file) 
    name = baseName.split('.')

with open(file) as f:
    txt = f.read()

    with open('../output/{}.json'.format(name[0]), 'w') as outFile:
        json.dump(tone_analyzer.tone(text=txt, sentences='false'), outFile, separators=(',', ': '), indent=2)

我收到错误：

WatsonException: Error: Invalid JSON input, Code: 400

当我尝试在此网络链接上手动输入文字时：https://tone-analyzer-demo.mybluemix.net/

我收到错误：request entity too large

请告知我如何从ToneAnalyzerV3获得json格式所需的音调分析分数。

查看Tone Analyzer API Explorer，您可以看到每个请求可以处理的文本数量有限制：

Tone Analyzer服务支持最多128 KB的文本，或大约1000 句子。不能分析少于三个单词的句子。

Tone Analyzer API Explorer

您提供的文本为165,743字节（168 KB），大于服务支持的内容。我尝试在API Explorer中输入上面提供的文本，并收到与上面相同的错误：

{
  "code": 400,
  "sub_code": "C00013",
  "error": "Invalid JSON input"
}

作为解决方案，您需要使用低于最大128 KB文本的文本输入。
