[英]Angular2. HTTP.POST doesn't work
this is my HTTP service right here : 这是我的HTTP服务:
postData(name, country) {
var body = JSON.stringify({
"name":name,
"country":country
});
console.log(name); // it outpus the correct value
console.log(country); // it outpus the correct value
return this.http.post('http://178.62.58.150:5000/api/cosmo/',body)
.map(res => {
res.text();
console.log(res.text());
})
.do(data => {
this.data = data;
// console.log(this.data);
})
}
It seems that it doesn't send the body to the POST request. 似乎它不会将正文发送到POST请求。
these output the correct value of the body 这些输出正确的身体价值
console.log(name);
console.log(country);
But 但
console.log(res.text());
It gives me a DB validation Error, which states that the body and country are required... 它给了我一个DB验证错误,该错误指出必须输入正文和国家/地区 ...
How do I send the body correctly? 如何正确发送尸体?
PS : I tested this with POSTMAN and it works! PS:我用POSTMAN测试了它,它可以工作!
Looks like the issue is in building the post params, try 看起来问题出在建立post params中,尝试
var body = JSON.stringify({
name: name,
country: country
})
Note that my hash keys are not strings, because stringify
will convert a JavaScript object to a JSON string. 请注意,我的哈希键不是字符串,因为
stringify
会将JavaScript对象转换为JSON字符串。
If this doesn't work, check with Google Developer tool on what your request is sending to the server. 如果这不起作用,请使用Google Developer工具检查您向服务器发送的请求。
I have added 我已经添加了
let headers = new Headers();
headers.append("Content-Type","application/json");
return this.http.post('http://178.62.58.150:5000/api/cosmo/',body,{headers:headers})
