Question

我想从Parse.com云代码中获取相同的HTTP响应，调用Parse.Cloud.httpRequest，因为我已经从cUrl获得了。但我无法得到它。有谁知道我做错了什么？

cUrl示例：

curl https://api.chain.com/v2/bitcoin/transactions/917673efa435b483343ddfe373995df365260c617107d3f9de68abd4e97c981b/confidence?api-key-id=e8d5ed773cf24e31c149ae874eb23c74

来自cUrl的回复：

{
 "transaction_hash":"917673efa435b483343ddfe373995df365260c617107d3f9de68abd4e97c981b",
 "block_hash":"0000000000000000042568aae3c297f687caa1b7737d8dab8e7d7b5087fb87f5",
 "propagation_level":null,
 "double_spend":null
}

解析云代码示例：

Parse.Cloud.httpRequest({
  method: 'GET',
  url: "https://api.chain.com/v2/bitcoin/transactions/917673efa435b483343ddfe373995df365260c617107d3f9de68abd4e97c981b/confidence",
  params: {
    "api-key-id": "e8d5ed773cf24e31c149ae874eb23c74"
  },
  headers: {
    'Content-Type': 'application/json'
  }
}).then(function (httpResponse) {
    console.log("httpResponse:");
    console.log("status:" + httpResponse.status);
    console.log("text:" + httpResponse.text);
    console.log("headers:");
    console.log(httpResponse.headers);
  }, function (httpResponseError) {
      console.error('httpResponse failed with response code ');
      console.log(httpResponseError);
  });

来自Parse的HTTP响应记录如下：

我在响应的Parse日志中看到了不可读的数据。有可能解决它吗？

该内容采用gzip编码。线索在响应标题中 - 有一个“Content-Encoding”：返回“gzip”标题。

如果要在CURL中使用相同的输出，请尝试以下命令

curl -X "GET" "https://api.chain.com/v2/bitcoin/transactions/917673efa435b483343ddfe373995df365260c617107d3f9de68abd4e97c981b/confidence?api-key-id=e8d5ed773cf24e31c149ae874eb23c74" \
-H "Accept-Encoding: gzip" \
-H "Content-Type: application/json"

您可以通过在Accept-Encoding标头中传递标识来关闭gzip编码。

curl -X "GET" "https://api.chain.com/v2/bitcoin/transactions/917673efa435b483343ddfe373995df365260c617107d3f9de68abd4e97c981b/confidence?api-key-id=e8d5ed773cf24e31c149ae874eb23c74" \
-H "Accept-Encoding: identity" \
-H "Content-Type: application/json"

或者在您的云代码中......

Parse.Cloud.httpRequest({
  method: 'GET',
  url: "https://api.chain.com/v2/bitcoin/transactions/917673efa435b483343ddfe373995df365260c617107d3f9de68abd4e97c981b/confidence",
  params: {
    "api-key-id": "e8d5ed773cf24e31c149ae874eb23c74"
  },
  headers: {
    'Content-Type': 'application/json',
    'Accept-Encoding': 'identity'
  }
}).then(function (httpResponse) {
  ....

我没有对此进行测试，但希望 Parse不会覆盖您设置的值。

Parse.Cloud.httpRequest httpresponse与cUrl响应不匹配
