Javascript 为什么我能'；t使用Jquery传递简单数组

我有一些简单的代码

HTTP状态400–错误请求 类型状态报告

消息所需字符串[]参数“testCaseNames”不存在

当它使用chrome开发者工具清晰地位于formData部分时

flowName: gsaasggsa
params[]: QUERY=select 1 from cuvar
params[]: PASSWORD=xasf
params[]: USERNAME={{ 0.OUTPUT }}
params[]: PASSWORD=xxx
params[]: USERNAME={{ 0.OUTPUT }}
testCaseNames[]: sql_test
testCaseNames[]: test_loginFail
testCaseNames[]: test_loginSuccess

我在这里错过了什么？为什么我不能通过它

$.ajax({
    type: 'post',
    url: "/flow/import",
    data: {
        linkageObject: linkageObject,
        flowName: flowName,
        params: params,
        testCaseNames: testCaseNames
    },
    success: function() {
        new PNotify({
            title: 'Flow Creation',
            text: 'Flow was imported successfully. It is available for use',
            type: 'success'
        });
        location.href = "/execute-flow";
    }
});

控制器

@RequestMapping(value = "/flow/import" , method = RequestMethod.POST
public @ResponseBody String importFlow(
    HttpSession session,
    @RequestParam("flowName") String flowName,
    @RequestParam("testCaseNames") String[] testCaseNames,
    @RequestParam(value = "params", required = false) String[] params,
    @RequestParam(value = "linkageObject", required = false) String linkageObject) { 

}

编辑：我没有放置linkageObject

linkageObject=%22%7B%5C%22operators%5C%22%3A%7B%5C%22operator0%5C%22%3A%7B%5C%22top%5C%22%3A160%2C%5C%22left%5C%22%3A640%2C%5C%22properties%5C%22%3A%7B%5C%22title%5C%22%3A%5C%22sql_test+(SQL)%5C%22%2C%5C%22inputs%5C%22%3A%7B%5C%22input_0%5C%22%3A%7B%5C%22label%5C%22%3A%5C%22QUERY%5C%22%7D%7D%2C%5C%22outputs%5C%22%3A%7B%5C%22output_0%5C%22%3A%7B%5C%22label%5C%22%3A%5C%22OUTPUT%5C%22%7D%7D%7D%7D%2C%5C%22operator1%5C%22%3A%7B%5C%22top%5C%22%3A260%2C%5C%22left%5C%22%3A920%2C%5C%22properties%5C%22%3A%7B%5C%22title%5C%22%3A%5C%22test_loginFail+(CSR)%5C%22%2C%5C%22inputs%5C%22%3A%7B%5C%22input_0%5C%22%3A%7B%5C%22label%5C%22%3A%5C%22USERNAME%5C%22%7D%2C%5C%22input_1%5C%22%3A%7B%5C%22label%5C%22%3A%5C%22PASSWORD%5C%22%7D%7D%2C%5C%22outputs%5C%22%3A%7B%7D%7D%7D%2C%5C%22operator2%5C%22%3A%7B%5C%22top%5C%22%3A100%2C%5C%22left%5C%22%3A920%2C%5C%22properties%5C%22%3A%7B%5C%22title%5C%22%3A%5C%22test_loginSuccess+(CSR)%5C%22%2C%5C%22inputs%5C%22%3A%7B%5C%22input_0%5C%22%3A%7B%5C%22label%5C%22%3A%5C%22USERNAME%5C%22%7D%2C%5C%22input_1%5C%22%3A%7B%5C%22label%5C%22%3A%5C%22PASSWORD%5C%22%7D%7D%2C%5C%22outputs%5C%22%3A%7B%7D%7D%7D%7D%2C%5C%22links%5C%22%3A%7B%5C%221%5C%22%3A%7B%5C%22fromOperator%5C%22%3A%5C%22operator0%5C%22%2C%5C%22fromConnector%5C%22%3A%5C%22output_0%5C%22%2C%5C%22fromSubConnector%5C%22%3A0%2C%5C%22toOperator%5C%22%3A%5C%22operator2%5C%22%2C%5C%22toConnector%5C%22%3A%5C%22input_0%5C%22%2C%5C%22toSubConnector%5C%22%3A0%7D%2C%5C%222%5C%22%3A%7B%5C%22fromOperator%5C%22%3A%5C%22operator0%5C%22%2C%5C%22fromConnector%5C%22%3A%5C%22output_0%5C%22%2C%5C%22fromSubConnector%5C%22%3A0%2C%5C%22toOperator%5C%22%3A%5C%22operator1%5C%22%2C%5C%22toConnector%5C%22%3A%5C%22input_0%5C%22%2C%5C%22toSubConnector%5C%22%3A0%7D%7D%2C%5C%22operatorTypes%5C%22%3A%7B%7D%7D%22&flowName=gsaasggsa&params%5B%5D=QUERY%3Dselect+1+from+cuvar&params%5B%5D=PASSWORD%3Dxasf&params%5B%5D=USERNAME%3D%7B%7B+0.OUTPUT+%7D%7D&params%5B%5D=PASSWORD%3Dxxx&params%5B%5D=USERNAME%3D%7B%7B+0.OUTPUT+%7D%7D&testCaseNames%5B%5D=sql_test&testCaseNames%5B%5D=test_loginFail&testCaseNames%5B%5D=test_loginSuccess

在Chrome developer tools的“网络”选项卡下，您是否可以获取

表单数据/请求有效负载

“原始”数据（单击

查看源代码

）然后把这些信息放在你的问题中？另外，在

请求标题中
内容类型说什么？内容类型：text/html；charset=utf-8。我将在编辑中发布源代码。在有人说是关于linkageObject之前，并不是因为如果我删除，我会得到相同的错误。你提交的是testCaseNames[]…因此，在java代码中尝试
@RequestParam（“testCaseNames[]）
@Joschi-lol它起作用了。。。
