获取TypeError:Python中的字符串索引必须是整数

我正在尝试使用API从网站获取数据

我的代码如下：

import requests
import json
import urllib2, base64
import sys

proxy = urllib2.ProxyHandler({'https': 'http://proxy.wdf.sap.corp:8080'})
opener = urllib2.build_opener(proxy)
urllib2.install_opener(opener)

username='xxx@xxx.com' # API Username
password='xxxxxxxxxxxxxxxxxxx' # API Password Token Code
THOUSANDEYES_API_URL='https://api.thousandeyes.com/v6/usage.json'


request = urllib2.Request(THOUSANDEYES_API_URL)
base64string = base64.encodestring('%s:%s' % (username, password)).replace('\n', '')
request.add_header("Authorization", "Basic %s" % base64string)
result = urllib2.urlopen(request)
data = json.load(result)

#save output in text file

orig_stdout = sys.stdout
f = open ('usage.txt', 'w')
sys.stdout = f

#print data

for i in data['usage']:
        print "Month Start: " + i['monthStart']
        print "Month End: " + i['monthEnd']
        print "Account Group Name:  " + i['accountGroupName']
        print "Test Name: " + i['testName']
        print "\n"

sys.stdout = orig_stdout
f.close()

当我运行此脚本时，我发现以下提到的错误：

回溯（最后一次调用）：文件“/te\u license\u usage.py”， 第32行，输入 打印“月开始：”+i['monthStart']类型错误：字符串索引必须是整数

请建议解决方案。

您不需要迭代

数据。

不是列表

试试看：

print "Month Start: " + data['usage']["quota"]['monthStart']         #Key "quota"
print "Month Start: " + data['usage']["quota"]['monthEnd']
for j in data['usage']['tests']:                                     #Iterate Key 'tests'
    print "Account Group Name:  " + j['accountGroupName']
    print "Test Name: " + j['testName']

Month Start: 2016-04-28 00:00:00
Month Start: 2016-05-28 00:00:00
Account Group Name:  Documentation
Test Name: https://app.thousandeyes.com
Account Group Name:  Documentation
Test Name: https://support.thousandeyes.com

输出：

print "Month Start: " + data['usage']["quota"]['monthStart']         #Key "quota"
print "Month Start: " + data['usage']["quota"]['monthEnd']
for j in data['usage']['tests']:                                     #Iterate Key 'tests'
    print "Account Group Name:  " + j['accountGroupName']
    print "Test Name: " + j['testName']

Month Start: 2016-04-28 00:00:00
Month Start: 2016-05-28 00:00:00

data['usage']

包含一个列表，如错误中所示：

 print "Month Start: " + i['monthStart'] TypeError: string indices must be integers

所以使用

数据['usage'][0]

：

for i in data['usage'][0]:
    print "Month Start: " + i['monthStart']
    print "Month End: " + i['monthEnd']
    print "Account Group Name:  " + i['accountGroupName']
    print "Test Name: " + i['testName']
    print "\n"

嗨，拉凯什，谢谢你的支持。我仍然收到相同的错误。对于数据中的I['usage']：print“Month Start:”+I[“quota”['monthStart']print“Month End:”+I[“quota”['monthEnd']对于I['tests']中的j:+I[“quota”['monthEnd']print“帐户组名称：”+j['accountGroupName']print“测试名称：”+j['testName']回溯（最近一次调用）：文件“/te_license_usage.py”，第32行，打印“月开始：”+i[“quota”][“monthStart”]类型错误：字符串索引必须是整数更新的snippet.Great。它现在正在工作。感谢Rakesh对您的大力支持。欢迎您。如果您可以发布一组返回的虚拟数据，这将非常有用。该站点请求登录证书，因为它不工作。正在执行以下错误回溯（最近一次调用last）：文件“/te_license_usage.py”，第31行，in for i in data['usage'][0]：KeyError:0
