问题描述
我需要解码一个字符串,并告诉它是否成功。我需要先调用/dummy.do
来对someString进行编码。 /displayapp
将使用其输出来解码并在解码的字符串中找到某些内容,然后返回shortString和成功值。
当我在浏览器中运行此代码时,我可以从/dummy.do
和/displayapp
获得响应并呈现。 /dummy.do
的响应为“长字符串”,而/displayapp
的响应为“短字符串”和“ true”。我什至可以在日志中获取“主机名未提供”。
当我在Postman中测试/dummy.do
时,我可以得到“长字符串”。但是,当我在Postman中测试/displayapp
时,我无法输出任何内容。
两个响应状态均为200,所以我不知道为什么它没有显示。如果已将其部署在我们的服务器中,则/displayapp
SampleUI.tsx
axios.post(contextpath + '/dummy.do',someString,{
transformRequest: [
(data,headers) => {
const formData = new FormData();
formData.set('someString',someString);
return formData;
}
]
})
.then(function (response) {
console.log('response dummy',response)
let longString = response.data.longString
let hostname = window.location.hostname
axios.post(contextpath + '/displayapp',{ longString,hostname },{
transformRequest: [
(data,headers) => {
const formData = new FormData();
formData.set('longString',longString);
formData.set('hostname',hostname);
return formData;
}
]
})
.then(function (response) {
console.log('response displayapp',response)
if (hostname == 'prodUrl.here') {
if (response.data.success == 'true') {
// some code here
}
else {
// some code here
}
}
else {
console.log('hostname not prod')
ReactDOM.render(<Main />,document.getElementById('root'));
}
})
})
SampleController.java
@RestController
public class SampleController {
@RequestMapping(value = "/dummy.do",method = RequestMethod.POST)
public Map<String,Object> dummy(HttpServletRequest request,HttpServletResponse response,String someString) throws Exception {
HashMap<String,Object> resultMap = new HashMap<String,Object>();
// will do some encoding of someString and will assign it to longString
// say value of longString is "Long String"
resultMap.put("longString",longString);
return resultMap;
}
@RequestMapping(value = "/displayapp")
public Map<String,Object> displayapp(HttpServletRequest request,String longString,String hostname) throws Exception {
HashMap<String,Object>();
// will do some decoding of longString,find something from the string and will assign it to shortString
// say value of shortString is "Short String"
resultMap.put("shortString",shortString);
resultMap.put("success","true");
return resultMap;
}
}```
