Question

我正在尝试使用配置解析器读取文件路径，然后从该文件读取

>>> cfg_file = './crawler.config'                                                                                          
>>> config = SafeConfigParser()                                                                                            
>>> config.read(cfg_file)
['./crawler.config']
>>> f = config.get('default', 'sites_file')
>>> with open(f) as fp:
...     print fp.read()
... 
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
IOError: [Errno 2] No such file or directory: u'"/home/avi/src/typo.csv"'
>>>

我认为Unicode存在问题。我无法找到解决方案。如果我直接将文件名作为字符串传递它可以正常工作。任何帮助解决这个问题都将受到赞赏。

Answer 1

(function($) {
  var dom;

  /* Cache the necessary DOM nodes for this module. */
  var cacheDOM = function() {
    dom = {};
    dom.document = $(document);
    dom.template = dom.document.find('#tmplt');
    dom.inputModal = dom.template.find('.modal__input');           // that's empty
    dom.formCircle = dom.template.find('.modal__form--invalid');   // that's empty
  };

  /* Change the image based on the validity of the input's value. */
  var inputModalValid = function() {
    var
      /* Cache the child nodes of the template's own DOM. */
      nodes = $(dom.template.prop('content').children),

      /* Cache the input and the image. */
      $input = nodes.find('.modal__input'),
      $check = nodes.find('.modal__form--invalid');

    /* Set an event listener for the 'keyup' event. */
    $input.on('keyup', function() {
      /* Check the validity of the input. */
      if (this.checkValidity() == true) {
        $check.attr("src", 'src/images/checkmark-circle.png');
      } else {
        $check.attr("src", "src/images/circle-form.png");
      }
    });
  }

  /* Initialize the module. */
  cacheDOM();
  inputModalValid();
}(jQuery));

可能是＆＃34; /home/avi/src/typo.csv"

不存在

f = config.get('default', 'sites_file')

您正在尝试阅读不存在的文件

Answer 2

尝试将配置中＆＃39; sites_file＆＃39; 的值从/home/avi/src/typo.csv更改为"/home/avi/src/typo.csv"

或

在打开文件之前替换引号。

例如：

with open(f.replace('"', '')) as fp: print fp.read()

在python中打开文件的奇怪错误
