如何在JMeter中的POST主体中转义\ r \ n

I have a JSON response as follows,

我有一个JSON响应如下,

{ "name":"John Smith", "address": "#123\r\nRenault Road\r\n123456\r\n" }

{“name”:“John Smith”,“address”:“#123 \ r \ nRenault Road \ r \ n \ n123456 \ r \ n”}

and I need to extract the address and put it into my next POST request. I use the JSON Extractor as a post processing element and with $..address I set the extracted address to the variable address.

我需要提取地址并将其放入我的下一个POST请求中。我使用JSON Extractor作为后处理元素,使用$ ..地址我将提取的地址设置为变量地址。

In my next request, I use the following as the POST data,

在我的下一个请求中,我使用以下作为POST数据,

{ "id": "123456", "address": "${address}" }

{“id”:“123456”,“地址”:“$ {address}”}

So when I make the request I see the POST data as,

所以当我发出请求时,我看到POST数据为,

{ "id": "123456", "address": "#123 Renault Road 123456 " }

{“id”:“123456”,“地址”:“#123 Renault Road 123456”}

This breaks at my backend and nevertheless this payload is not identified as a valid JSON as well.

这在我的后端中断,然而这个有效负载也没有被识别为有效的JSON。

I want to make the request so that the POST data is as follow,

我想发出请求,以便POST数据如下,

{ "id": "123456", "address": "#123\r\nRenault Road\r\n123456\r\n" }

{“id”:“123456”,“address”:“#123 \ r \ nRenault Road \ r \ n \ n123456 \ r \ n”}

Any help to get this done is highly appreciated.

任何帮助完成这项工作的人都非常感谢。

If you really need to send these line breaks as \r\n you can use some scripting to convert them back.

如果您确实需要将这些换行符发送为\ r \ n,则可以使用某些脚本将其转换回来。

Add Beanshell PreProcessor as a child of the "next request" HTTP Request Sampler

将Beanshell PreProcessor添加为“下一个请求”HTTP请求采样器的子级

Put the following code into the PreProcessor's "Script" area:

将以下代码放入PreProcessor的“脚本”区域:
```
address = vars.get("address");
address = address.replaceAll("\\r\\n","\\\\r\\\\n");
vars.put("address", address);
```

The above script will convert line breaks to the textual representation.

上面的脚本会将换行符转换为文本表示。

vars is a shorthand for JMeterVariables class instance, it provides read/write access to all JMeter Variables

vars是JMeterVariables类实例的简写,它提供对所有JMeter变量的读/写访问

String.replaceAll() - is the method of String class which comes out of box with Java SDK
