python解析URL中含有特殊符号的地址

摘要

今天在用curl调用一个solr地址查询数据的时候报错，发现是因为URL地址中含有[ 中括号 导致的，既然shell的curl命令不行，想着Python的urllib包可以解析URL地址，那就尝试这个

curl 执行报错

错误的情况：

root@pts/3 $ curl "http://192.168.xxx.xxx:8983/solr/core1_shard2_replica1/select?q=*:*&fq=sex:1&fq=activeTime_tdt:[NOW-20MINUTE TO NOW]&wt=json&indent=true"
curl: (3) [globbing] error: bad range specification after pos 96

如果去掉中间包含中括号的查询条件则用curl没有问题

root@pts/3 $ curl "http://192.168.xxx.xxx:8983/solr/core1_shard2_replica1/select?q=*:*&fq=sex:1&wt=json&indent=true"
{
  "responseHeader":{
    "status":0,
    "QTime":8,
    "params":{
      "q":"*:*",
      "indent":"true",
      "fq":"sex:1",
      "wt":"json"}},
      ...

python urllib

这里给出具体的例子

root@pts/3 $ python
Python 2.7.5 (default, Nov 20 2015, 02:00:19)
[GCC 4.8.5 20150623 (Red Hat 4.8.5-4)] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> import urllib
>>> urlstr = "http://192.168.xxx.xxx:8983/solr/core1_shard2_replica1/select?q=*:*&fq=sex:1&fq=activeTime_tdt:[NOW-20MINUTE TO NOW]&wt=json&indent=true"
>>> result = urllib.urlopen(urlstr)
>>> print(result)
36354168 whose fp = 0x7f437fe03c50>>
>>> print(result.read())
{
  "responseHeader":{
    "status":0,
    "QTime":11,
    "params":{
      "q":"*:*",
      "indent":"true",
      "fq":["sex:1",
        "activeTime_tdt:[NOW-20MINUTE TO NOW]"],
      "wt":"json"}},

最后可以结合Python的正则表达式来等来实现自己个性化的需求
