如何将json传递给nodejs请求发布方法？

Question

我尝试将json传递给nodejs post方法。但是我收到错误“必须指定搜索查询。”。我已经指定了搜索字符串并过滤了代码。你能建议导致这个错误的原因吗？

POSTMAN中的相同请求。

//Load the request module 
var express = require('express'); 
var request = require('request'); 
var app = express(); 

//Lets configure and request 
request({ 
    url: 'http://host:8080/rest/1.0/search', 
    qs: {query: 'nodejs*'}, 
    method: 'POST', 
    json: { 
     filter: 
     { 
      community: ['33862a97-44e5-4de5-9206-db0a61dd83ca'], 
      vocabulary: ['b80f3576-0642-4049-bb07-d72a0dd9e3e0','48029bb8-0585-4ed5-afaa-55014aebfcb3'], 
      type: {asset:['00000000-0000-0000-0000-000000011001']}, 
     }, 
     fields: ['name'] 

    } 
}, function(error, response, body){ 
    if(error) { 
     console.log(error); 
    } else { 
     console.log(response.statusCode, body); 
} 
}); 
app.listen(8080);

根据你postman截图可以通过摆脱qs: {query: 'nodejs*'}并添加json内同一尝试下面的代码。

//Load the request module 
var express = require('express'); 
var request = require('request'); 
var app = express(); 

//Lets configure and request 
request({ 
    url: 'http://host:8080/rest/1.0/search', 
    method: 'POST', 
    json: { 
     query: 'nodejs*', 
     filter: 
     { 
      community: ['33862a97-44e5-4de5-9206-db0a61dd83ca'], 
      vocabulary: ['b80f3576-0642-4049-bb07-d72a0dd9e3e0','48029bb8-0585-4ed5-afaa-55014aebfcb3'], 
      type: {asset:['00000000-0000-0000-0000-000000011001']}, 
     }, 
     fields: ['name'] 

    } 
}, function(error, response, body){ 
    if(error) { 
     console.log(error); 
    } else { 
     console.log(response.statusCode, body); 
} 
}); 
app.listen(8080);
