HTTP请求字符串解析

时间：2025-03-20 07:46:04

开发物流项目，编写接口的时候，遇到了这样的一个url需要解析，url如下：

http://***/get?$filter=(CreatedOn ge datetime'2016-07-21T00%3A00%3A00') and (SortFlag eq 'A') and(PhoneNo eq '13486391009') and (Execution eq '02' or Execution eq'03')&$top=1&$skip=0&$expand=NavCustomerPurchaseOrder

如果是使用$链接的字符串，可以直接使用spring的参数方式接收

@ResponseBody
@RequestMapping("/get")
public Map getDriverFreightOrder(@RequestParam(value="$filter",required=true) String filter,
@RequestParam(value="$top",required=false) Integer top,
@RequestParam(value="$skip",required=false) Integer skip,
@RequestParam(value="$TorId",required=false) String torId) {

通过这样解析之后，变量都可以获取对应的值，现在的问题就是对filter=(CreatedOn ge datetime'2016-07-21T00%3A00%3A00') and (SortFlag eq 'A') and(PhoneNo eq '13486391009') and (Execution eq '02' or Execution eq'03')这个字符串进行解析

1、当时太忙了，懒得思考，就用了最原始的方法（事实证明写程序懒不得，要有足够充分的思考，不然后面会浪费更多的时间，还会影响）

（按照位置使用indexOf取值）

		String filter = "(CreatedOn ge datetime'2016-07-21T00%3A00%3A00') and (SortFlag eq 'A-A') and (PhoneNo eq '15717177064') and (Execution eq '0-2' or Execution eq '0-3') and (ProcessStatus eq '20' or ProcessStatus eq '1-0' or ProcessStatus eq '3---0')";
		String PhoneNo = null;
		String Execution = null;
		String SortFlag = null;
		String startDateString = null;
		String endDateString = null;
		String tempProcessStatus = null;

		if (("PhoneNo eq")) {
			int b = ("PhoneNo eq");
			String tempString = (b);
			PhoneNo = (12, 23);
			(PhoneNo);
		}



2、后来接口调用的时候出问题了，因为方法一是按照固定长度取值的，比如说PhoneNo eq '13486391009'，一点长度发生变化，比如变成PhoneNo eq '134'，长度不一致，接口妥妥滴会报错。后来改进了这个方法，示例如下：通过定位左右单引号来定位字符串，就不会出现长度取值错误的情况了。

filter=(CreatedOn ge datetime'2016-07-21T00%3A00%3A00') and (SortFlag eq 'A') and(PhoneNo eq '13486391009') and (Execution eq '02' or Execution eq'03')
String tempString = null;
if (("PhoneNo eq")) {
//截取为PhoneNo eq '10000000000001') and (Execution eq '0-2' or Execution eq '0-3')
tempString = (("PhoneNo eq"));
//截取为10000000000001') and (Execution eq '0-2' or Execution eq '0-3')
//tempString = (("'")+1);
tempString = ("PhoneNo eq '", "");
//截取为10000000000001
PhoneNo = (0,("'"));
(PhoneNo);

}
if (("Execution eq")) {
tempString = (("Execution eq"));
tempString = (("'")+1);
Execution = (0,("'"));
(Execution);
}
if (("SortFlag eq")) {
tempString = (("SortFlag eq"));
tempString = (("'")+1);
SortFlag = (0,("'"));
(SortFlag);
}
if (("CreatedOn ge")) {
tempString = (("CreatedOn ge"));
tempString = (("'")+1);
startDateString = (0,("'"));
(startDateString);
startDateString = ("T", " ");
}
if (("CreatedOn le")) {
tempString = (("CreatedOn le"));
tempString = (("'")+1);
endDateString = (0,("'"));
(endDateString);
endDateString = ("T", " ");
}


// 对$ProcessStatus的解析
List<String> processStatusList = new ArrayList<String>();
while (("ProcessStatus eq")) {
tempString = (("ProcessStatus eq"));
tempString = (("'")+1);
tempProcessStatus = (0,("'"));
(tempProcessStatus);
filter = ("ProcessStatus eq", " ");
}


3、方法二算是能够满足解决方案，但是结果还是太麻烦了一点，后来同事告知一种方法，使用replace来解决，确实方便了很多。

filter=(CreatedOn ge datetime'2016-07-21T00%3A00%3A00') and (SortFlag eq 'A') and(PhoneNo eq '13486391009') and (Execution eq '02' or Execution eq'03')
String[] list = (" and ");
List<String> processStatusList = new ArrayList<String>();
for(String tempString:list ){
if (("PhoneNo eq")) {
PhoneNo = ().replace("(PhoneNo eq '", "").replace("')", "");
}
if (("Execution eq")) {
Execution = ().replace("(Execution eq '", "").replace("')", "").substring(0,2);
}
if (("SortFlag eq")) {
SortFlag = ().replace("(SortFlag eq '", "").replace("')", "");
}
if (("CreatedOn ge")) {
(tempString);
startDateString = ().replace("(CreatedOn ge datetime'", "").replace("')", "");
startDateString = ("T", " ");
}
if (("CreatedOn le")) {
endDateString = ().replace("(CreatedOn le datetime'", "").replace("')", "");
endDateString = ("T", " ");
}
while (("ProcessStatus eq")) {
(tempString);
int b = ("ProcessStatus eq");
tempProcessStatus = (b + 18, b + 20);
(tempProcessStatus);
tempString = ("ProcessStatus eq", " ");
}
}

以下是完整的代码，可以直接运行测试

	public static void main(String[] args) {
