python curl

要通过python'；s子进程或pycurl,python,curl,subprocess,pycurl,Python,Curl,Subprocess,Pycurl,我有以下命令，它将用户添加到gerrit实例的管理员组中 curl -X POST -H "Content-Type:application/json;charset=UTF-8" -u nidhi:pswd http://host_ip:port/a/groups/Administrators/members.add -d '{"members":["user@example.com"]}' 当我在终端上运行这个命令时，它运行得很好，并给出了预期的输出但是，我想在python中使用子进程

我有以下命令，它将用户添加到

gerrit

实例的管理员组中

 curl -X POST -H "Content-Type:application/json;charset=UTF-8" -u nidhi:pswd http://host_ip:port/a/groups/Administrators/members.add -d '{"members":["user@example.com"]}'

当我在终端上运行这个命令时，它运行得很好，并给出了预期的输出

但是，我想在python中使用

子进程

或

pycurl

库执行此命令

使用

子流程

我编写了以下代码

def add_user_to_administrator(u_name,url):
    bashCommand = 'curl -X POST -H "Content-Type:application/json;charset=UTF-8" -u nidhi:pswd http://'+url+'/a/groups/Administrators/members.add -d '+"'"+'{"members":["$u_n@example.com"]}'+"'"
    bashCommand = string.Template(bashCommand).substitute({'u_n':u_name})
    print bashCommand.split()
    process = subprocess.Popen(bashCommand.split())

它不显示任何错误，但在管理员组中看不到任何更改

我使用

pycurl

尝试了同样的方法

def add_user_to_administrator2(u_name,url):
    pf = json.dumps({"members":[str(str(u_name)+"@example.com")]})
    headers = ['Content-Type:application/json;charset=UTF-8']
    pageContents = StringIO.StringIO()


    p = pycurl.Curl()
    p.setopt(pycurl.FOLLOWLOCATION, 1)
    p.setopt(pycurl.POST, 1)
    p.setopt(pycurl.HTTPHEADER, headers)
    p.setopt(pycurl.POSTFIELDS, pf)
    p.setopt(pycurl.WRITEFUNCTION, pageContents.write)
    p.setopt(pycurl.VERBOSE, True)
    p.setopt(pycurl.DEBUGFUNCTION, test)
    p.setopt(pycurl.USERPWD, "nidhi:pswd")
    pass_url=str("http://"+url+"/a/groups/Administrators/Administrators/members.add").rstrip('\n')
    print pass_url
    p.setopt(pycurl.URL, pass_url)
    p.perform()

    p.close() 
    pageContents.seek(0)
    print pageContents.readlines()

这会引发一个错误，它找不到帐户

成员

提到的变量

url

的形式为host\u ip:port

为了纠正这些错误，我做了很多努力。我不知道我哪里出错了。任何帮助都将不胜感激

您应该尝试[
```
urllib2
```
]（
```
python2
```
）或（
```
python3
```
）发布json数据
对于
```
subprocess.Popen
```
：
```
subprocess.Popen.communicate
```
（）可能会给您提供帮助，或者只需在shell中执行bash命令即可查看差异
对于
```
pycurl
```
，我没有使用它，但请您添加错误信息
