我正在使用nodejs 0.4.7发出请求,这是我的代码:
var post_data = JSON.stringify({
'compilation_level' : 'ADVANCED_OPTIMIZATIONS',
'output_format': 'json',
'warning_level' : 'QUIET',
'js_code' : code
});
var post_options = {
host: 'closure-compiler.appspot.com',
port: '80',
path: 'compile',
method: 'POST',
headers: {
'Content-Type': 'application/x-www-form-urlencoded',
'Content-Length': post_data.length
}
};
var post_req = http.request(post_options, function(res) {
res.setEncoding('utf8');
res.on('data', function (chunk) {
console.log('Response: ' + chunk);
});
});
post_req.write(post_data);
post_req.end();
我得到的回应是
Response: <HTML><HEAD><meta http-equiv="content-type" content="text/html;charset=utf-8">
<TITLE>302 Moved</TITLE></HEAD><BODY>
<H1>302 Moved</H1>
The document has moved
<A HREF="http://www.google.com/">here</A>.
</BODY></HTML>
为什么会这样?我究竟做错了什么 ?在tutorial中,它表示我已向@ {3}}发出POST请求...
答案 0 :(得分:5)
您正在尝试发送json数据:
var post_data = JSON.stringify({
'compilation_level' : 'ADVANCED_OPTIMIZATIONS',
'output_format': 'json',
'warning_level' : 'QUIET',
'js_code' : code
});
Google Closure Compiler API需要标准表单数据,因此您希望使用querystring
。您还需要指定所需的输出格式(我假设的编译代码),如指定的by their documentation:
var post_data = querystring.stringify({
'compilation_level' : 'ADVANCED_OPTIMIZATIONS',
'output_format': 'json',
'output_info': 'compiled_code',
'warning_level' : 'QUIET',
'js_code' : code
});
路径更好地声明如下:
path: '/compile',
以下是概念代码的完整证明:
var http = require('http');
var querystring = require('querystring');
var code ="// ADD YOUR CODE HERE\n" +
"function hello(name) {\n" +
" alert('Hello, ' + name);\n" +
"}\n" +
"hello('New user');\n";
var post_data = querystring.stringify({
'compilation_level' : 'ADVANCED_OPTIMIZATIONS',
'output_format': 'json',
'output_info': 'compiled_code',
'warning_level' : 'QUIET',
'js_code' : code
});
var post_options = {
host: 'closure-compiler.appspot.com',
port: '80',
path: '/compile',
method: 'POST',
headers: {
'Content-Type': 'application/x-www-form-urlencoded',
'Content-Length': post_data.length
}
};
var post_req = http.request(post_options, function(res) {
res.setEncoding('utf8');
res.on('data', function (chunk) {
console.log('Response: ' + chunk);
});
});
post_req.write(post_data);
post_req.end();
使用node.js
运行它会产生以下结果:
$ node test.js
Response: {"compiledCode":"alert(\"Hello, New user\");"}
