如何获取我的输出并删除此异常?
How can i get my output and remove this Exception?
预先感谢
推荐答案
要检查您的代码,我尝试了以下操作:
To check your code I tried the following:
@Test
public void test1() throws Exception {
System.setProperty("webdriver.chrome.driver", "t:\\Others\\chromedriver.exe");
WebDriver driver = new ChromeDriver();
String url = "http://www.upmandiparishad.in/commodityWiseAll.aspx";
driver.get(url);
Thread.sleep(5000);
new Select(driver.findElement(By.id("ctl00_ContentPlaceHolder1_ddl_commodity"))).selectByVisibleText("Paddy");
Thread.sleep(5000);
driver.findElement(By.id("ctl00_ContentPlaceHolder1_txt_rate")).sendKeys("27/03/2014");
Thread.sleep(5000);
driver.findElement(By.id("ctl00_ContentPlaceHolder1_btn_show")).click();
Thread.sleep(5000);
driver.close();
}
它可以与FireFox(29.0)和Chrome(34.0)驱动程序正常工作.我使用了以下jar-s:
It works fine with FireFox (29.0) and Chrome (34.0) drivers. I used the following jar-s:
- selenium-server-standalone-2.41.0.jar
- selenium-java-2.41.0.jar
- junit-dep-4.11.jar
- hamcrest-core-1.3.jar
您应该检查项目的构建路径并添加适当的jar.但是,如果打开它,则可以在selenium-server-standalone-2.XY.0.jar中找到丢失的类文件:selenium-server-standalone-2.41.0.jar \ org \ apache \ http \ entity \ ContentType
You should check your project build path and add the appropriate jar-s. But you can find the missing class file in the selenium-server-standalone-2.XY.0.jar if you open it: selenium-server-standalone-2.41.0.jar\org\apache\http\entity\ContentType
另一种方法是使用包含缺少的类文件的httpcore.jar(httpcore-4.3.jar).
Another way is to use httpcore.jar (httpcore-4.3.jar) that contains the missing class file.
