python - 如何使用 Robobrowser 提交带有获取操作的表单

Question

我正在使用 robobrowser 库，我遇到了一个表单:

<form action="/results" id="search">
            <div class="s_ctr">
                <fieldset>
                    <label class="jaw" for="ln">Search by Name</label><input type="text" placeholder="Search by Name" autocomplete="off" value="" tabindex="1" name="ln" maxlength="255" class="name" id="ln" data-key="true"><span>near</span><label class="jaw" for="loc">Enter City, State</label><input type="text" placeholder="Enter City, State" autocomplete="off" value="" tabindex="2" name="loc" maxlength="255" class="location" id="loc" data-key="true">
                </fieldset>
                <input type="submit" value="Find Physician" class="orange-btn" tabindex="4" id="btn-submit">

            </div>
        </form>

我的代码:

search_form = browser.get_form(id='search')
search_form        
search_form.fields['1']= name
search_form.fields['2']= address
# # Submit the form
browser.submit_form(search_form)
browser

我收到以下错误和回溯:

Traceback:

  114.                     response = wrapped_callback(request, *callback_args, **callback_kwargs)

  118.             payload.add(field.serialize(), field.payload_key)    

Exception Type: AttributeError at /ph/
Exception Value: 'unicode' object has no attribute 'serialize'

这个表单可以用robobrowser提交吗？

Answer 1

问题在于您设置表单域值的方式。要更改字段的值，请写入其 value 属性:

form.fields['ln'].value = name
# Or, as a shortcut...
form['ln'].value = name

您的示例代码实际上没有设置表单字段的值，而是用 unicode 对象替换了字段。运行 form['ln'] = name 不会将 ln 字段的值设置为 name；它删除 ln 字段并将其替换为name 字符串。然后，当表单尝试序列化其内容时，它会尝试调用其每个字段的 serialize 方法。但是字符串没有定义那个方法，这导致了你遇到的回溯。
