对节点快速服务器的 Angular 7.x 查询被转换为字符对象数组答案

【问题标题】：Angular 7.x query to node express server is converted to an object array of characters对节点快速服务器的 Angular 7.x 查询被转换为字符对象数组

【问题描述】：

我正在向 node express 服务器发送一个查询字符串。当我访问 req.query 属性时，它是一个字符数组，而不是普通对象或我发送的字符串。有什么想法吗？

已发送查询

const data = await this.cspCrudService.findOne(stringQuery);

服务

findAll(params: any): Promise<T[]> {
 THIS LINE BELOW WAS THE PROBLEM
 const query = StringUtil.toMongoQueryString(params);
 return this.httpClient.get<T[]>(`${this.url}${this.endpoint}/${query}`).toPromise();
}

"位置[$regex]=^F&location[$options]=i"

req.query


{"0":"l","1":"o","2":"c","3":"a","4":"t","5":"i","6":"o","7":"n","8":"[","9":"$","10":"r","11":"e","12":"g","13":"e","14":"x","15":"]","16":"=","17":"^","18":"F","19":"","20":"l","21":"o","22":"c","23":"a","24":"t","25":"i","26":"o","27":"n","28":"[","29":"$","30":"o","31":"p","32":"t","33":"i","34":"o","35":"n","36":"s","37":"]","38":"=","39":"i"}

你怎么寄的？插入Http请求的代码。
@MaihanNijat 在您请求代码后，我注意到了问题。我前段时间添加了“StringUtil.toMongoQueryString”函数并忘记了它在那里。删除后它起作用了。谢谢

我前段时间添加了一个“StringUtil.toMongoQueryString”函数进行测试，但忘记了它在那里。删除后一切正常。
