SyntaxError:JSON位置0处出现意外的令牌C-Ionic 2 Http GET请求 [英] SyntaxError: Unexpected token C in JSON at position 0 - Ionic 2 Http GET request

问题描述

我正在尝试执行GET请求并从响应中检索数据.

this.http.get('http://localhost:8888/maneappback/more-items.php').subscribe(res => {
    console.log(res.json());
}, (err) => {
    console.log(err);
});

我收到错误SyntaxError: Unexpected token C in JSON at position 0.我还假设该错误与请求有关.

在服务器端，我像这样(PHP)发送数据:

echo json_encode($array);

解决方案

我只是没有意识到我在脚本中仍然有两个echo语句...这就是为什么它不被识别为JSON的原因./p>

I am trying to perform a GET request and retrieve the data from the response.

this.http.get('http://localhost:8888/maneappback/more-items.php').subscribe(res => {
    console.log(res.json());
}, (err) => {
    console.log(err);
});

I am getting the error SyntaxError: Unexpected token C in JSON at position 0. I am also assuming that the error is related to the request.

On my server side, I have the data being sent like this (PHP):

echo json_encode($array);

解决方案

I was just neglecting to realize that I still had two echo statements in the script...that is why it wasn't recognized as JSON.
