Question

我正在使用apollo-fetch来获取graphql数据。我结束了一个脚本错误，请求没有通过。我不确定在这样一个相当简单的请求中出了什么问题。请帮忙。

这是错误：

Uncaught (in promise) Error: Network request failed to return valid JSON
    at throwHttpError (apollo-fetch.js:41)
    at apollo-fetch.js:141
    at <anonymous>
    throwHttpError @ apollo-fetch.js:41
    (anonymous) @ apollo-fetch.js:141
    Promise rejected (async)

以下是代码：

const { createApolloFetch } = require('apollo-fetch');

PlayService.prototype.getPlays = function(playID) {
  const fetch = createApolloFetch({
    uri: 'graphql'
  });

 const playQuery = `query ($playid: String) {
   plays(id: $playid) {
    id
    items {
      nodes {
        id
        name
      }
    }
   }
 }`;
 fetch({
    query: playQuery,
    variables: { playid: playID }
  }).then((res) => {
    console.log(res.data);
  });
};

我最好的猜测是你的uri值不正确。你应该提供像这样的完全合格的uri

PlayService.prototype.getPlays = function(playID) {
  const fetch = createApolloFetch({
    uri: 'http://localhost:3000/graphql'
  });

对于简单的garphql查询，apollo-fetch最终会出现网络错误
